Abstract: Apparatus for lining an irrigation canal with a sheet of fiber-reinforced plastic includes structure for depositing a layer of resin and fiber on a web of flexible carrier material, partially curing the resin prior to laying the sheet in the canal, and then laying the sheet in the canal while the resin is flexible enough to conform to the shape of the canal. The final curing of the resin takes place after the sheet is placed in the canal. A predetermined-shape wrinkle is induced in the carrier web before it is laid into the canal to assist in conforming the sheet to the canal shape without causing randomly placed wrinkles so that the sheet is smooth in the canal. The apparatus forms the sheet and is propelled so that it travels along the length of the canal, fabricating a continuous sheet as it travels. In one embodiment the carrier is a flexible but nonelastic material like kraft paper, coated on one side with wax or other film to prevent saturation by the resin.

Abstract: A process is provided for sealing a degas hole in a coal seam prior to mining of the coal therein which includes the steps of inserting a perforated liner into the degas hole substantially the entire length thereof and pumping grout down the center of the perforated liner to the end of the degas hole. As the end of the degas hole is filled with grout, pressure is increased to force grout through the perforations in the liner to fill the degas hole along the entire length thereof. The perforated liner is also useful in the election of methane gas prior to sealing of the degas hole and further ensures a clear path through the degas hole so that sloughing, or caving, of the degas hole prior to grouting does not interfere with the complete sealing of the degas hole.

Abstract: A movable form for lining irrigation ditches with concrete and simultaneously installing wire mesh into approximately the center of the wet concrete being poured.

Abstract: Method for the layered placing of upright or sloping dam cores of material bound with bitumen and/or plastic and/or a natural binder in a constant or upward-tapering thickness for dams such as barrage dams characterized in that the core material is placed from a silo of a travelling machine; that at the same time transitional material is placed, from one or more silos of that machine, alongside and against the placed core material; that the dam core is formed with the aid of a sliding formwork located on the machine to give lateral support to the core until and while the transitional material is placed; that the core material, immediately after it has been placed and before the transitional material is placed, is pre-compacted both vertically and laterally; and that subsequently the core material and the transitional material are (further) compacted.

Abstract: Reinforced concrete walls, particularly circular shafts are constructed in difficult and rocky ground by casting a pair of guide walls spaced apart a distance larger than the nominal thickness of the final wall structure and the trench excavation for the wall is carried out between the two guide walls. Initially, backfilling is of a plastic erodable mixture such as cement-bentonite, sand-cement-bentonite, which have no large aggregates. At the surface above the guide walls, forms are set for casting the reinforced structures which are to form the concrete wall per se and hollow pipes are embedded in the structure at spaced intervals, each with pipe couplings extending out of the concrete, along with the vertical runs of the steel reinforcing bars, for the next succeeding section. Water is then injected into the pipes gradually washing the erodable backfill material and facilitating the descent of the cast concrete section, which is lowered by jacks anchored to the guide walls.

Abstract: A paver embodying a vibrating pan for spreading concrete and smoothing and compacting the same on a sloping surface is described.

Abstract: Channel construction machinery is provided with a levelling and material lining application attachment to thus provide a continuous mode of channel construction operation in either the longitudinal or transverse direction of operation with respect to the longitudinal axis of the channel. The levelling and/or lining attachment is provided with at least one shaft which is mounted and driven so as to rotate. The length of the shaft is proportioned to the length of the embankment section to be worked on. Located about the circumference of the shaft are blade-like elements, whose surfaces are directed at an angle to the axis of the shaft. The shafts and angularly directed blades are mounted on implement carriers of the channel construction machine in a manner such that they oscillate by being connected to vibration actuators. The implement carriers, however, attached to the frame of the apparatus are isolated from the vibrations of the vibrator by damping elements.

Abstract: An apparatus is disclosed for the continuous longitudinal construction for canals. The apparatus performs a series of sequential operations required for the construction of a canal. The apparatus performs planing of the surfaces of the sidewall slopes of the canal and the canal bed followed by a smooth surfacing of the planed surfaces with a suitable planing material.The apparatus during the canal construction adjusts to the angle defined by the opposed sloped walls of the canal and is adapted so that the ground-engaging carriages are held against the sloped walls. In this manner, the heavy bridging structures which, in the prior art, extend from one berm of the canal, across the canal, and to the other berm, are eliminated. In addition, two or more apparatus frames are pivotally connected one behind the other. In this manner, continuous adjusting at the connecting hinge is performed as the canal is constructed according to the varying parameters of the canal.

Abstract: The canal paving machine has an elongated main frame supported in an elevated position on a pair of end frame structures each of which includes an upper mounting section, a lower traction section and an intermediate connecting section. One mounting section is movably supported on the main frame for movement longitudinally thereof to vary the longitudinal spacing between the end frame structures. Each traction section has front and rear traction units movably connected together to vary the spacing therebetween transversely of the main frame. The connecting section is vertically adjustable relative to the traction section and the upper mounting section is vertically adjustable relative to the connecting section. During a paving operation the upper sections are retracted relative to the connecting sections and the main frame adjusted relative to the ground surface by vertical adjustment only of the connecting sections.

Abstract: The open topped telescoping bunker body is filled from above and material in the body can be discharged when the tail gate at the rear is opened. A double acting push plate is used to push material through the open tail gate and material falling into the body ahead of the push plate during discharge can be ejected through the open front end of the body ahead of the plow blade. The plow blade levels the material to form a roadway as the skid mounted bunker is pulled forward. The blade can be raised to allow passage of men or material under the body. The push blade moves with and with respect to the moving part of the telescoping body.

A forming member (50) is supported for vertical movement at the open rear end of the hopper (41) and the forming member (50) with the sides and bottom of the ditch (10) together define an extrusion opening through which the concrete material passes. Control means (76) is associated with the forming member (50) for vertically adjusting the forming member (50) relative to the hopper (41) so that the slope, grade, or fall of the interior bottom wall (14) of the concrete lining is accurately controlled.

Abstract: An apparatus for distributing concrete, especially in the shuttering of gallery linings in mining and tunnel workings, comprises a transportable distribution mast carrying an articulated conduit for conveying concrete which is pivoted on a column which can rotate around its axis. The mast comprises a swivel extension forming the end section thereof, and a main boom which connects the column to the swivel extension, the swivel extension being foldable from above onto the main boom. The main boom is divided into several mast sections joined together by power-operated pivotal connections so that the mast is articulatable in a swivel plane containing the column axis, the range of relative pivotal movement between the mast sections being such that the main boom may be extended upwardly and forwardly from the folded position of the mast sections, with the swivel extension in its folded position, the power-operated pivotal connections of the main boom being disposed below the folded swivel extension.

Abstract: An earthen structure for holding back a body of water has a sloped surface which is paved with an overlapping arrangement of strips constructed of castable material. Each strip is formed by conveying castable material from a mobile receiving hopper that is propelled adjacent to the base of the earthen structure. A bridge conveyor projects laterally from the receiving hopper over the slope. The bridge conveyor deposits the castable material onto the slope forwardly of a spreader device that is advanced longitudinally relative to the slope by a prime mover. A scraper blade of the spreader device is positioned at a preselected elevation by a forwardly projecting sidewall which is connected to the blade and slidable on a previously formed strip. The sidewall maintains the castable material in front of the blade, as the advancing blade spreads the material in a longitudinal strip of a preselected thickness and having a lateral edge extending a preselected lateral dimension outwardly from the sloped surface.
