Abstract: A method for foundation consolidation combining vacuum preloading and geomembrane bag assembly loading, which comprises: digging a slurry pit, filling mud into the slurry pit and conducting vacuum preloading pumpdrainage for multiple times, laying the geomembrane bag assemblies above the soft slurry seam processed through vacuum preloading pumpdrainage inside the slurry pit to form a plurality of loading layers, and laying the geomembrane bag assemblies by piling geomembrane bags. In view of the engineering complexity and uneven settlement resulting from conventional vacuum preloading using slag loading, geomembrane bag for loading to overcome the adverse effects of slag loading. In the present invention, the drainage system and the geomembrane bag assemblies are laid out to fully leverage their perspective properties, so as to improve the transmission of vacuity in the whole soil mass, speed up the drainage rate, and increase the degree of consolidation.

Abstract: In a method for setting up a pipeline section of a pipe system in a heat network, which is provided for transferring a heat transfer fluid between a heat provider and a heat consumer, the pipeline section is subdivided into segments in a segmentation step. A segment characteristic variable is determined for each segment based on a physical soil characteristic variable. The determined segment characteristic variables of two adjacent segments differ by more than a predefined segment characteristic variable difference value. In a bedding determination step, segment embedding of a pipeline segment, introduced in the trench in this segment, in a water-permeable segment bedding material is predefined for each segment such that a heat loss of the heat transfer fluid transferred in the pipeline segment, which is averaged over the segment and is based on a unit of length, is lower than a predefined heat loss limit value.

Abstract: Delivery of a high volume of floating systems for wind turbines can make floating wind economic. The delivery can involve the standard design of sections, such as “tubes” or “cans,” comprising a rolled plate and ring stiffeners. The delivery can then involve the transportation of the sections in block to an assembly site that is closer to the planned installation point. The sections are used to manufacture floating vessels, such as semi-submersibles, buoyant towers, and/or spars, at the assembly site, which can include a barge with cranes. For semi-submersibles, the delivery can then involve the installation of the Tower, the nacelle, and blades using the barge cranes. Alternatively, for spars or buoyant towers, the nacelle and blades can be installed at an off-shore location using a platform, such as a standard jack-up vessel or a crane jacket.

Abstract: A cable puller and associated methods are shown. Useful example methods include pipe bursting using cable pullers as shown. Cable pullers and methods shown provide a mechanical advantage that increases an amount of cable pulled in one cycle. Selected examples are shown that include a pulley located on a distal end of a moving portion of an extending and contracting beam. The pulley and the mechanical advantage it supplies helps to improve the efficiency of the cable puller and reduce manufacturing cost of the cable puller.

Abstract: A boat lift is attached to piles driven into the earth or to another object. The boat lift is held in horizontal position relative to piles or the object to which it is attached, but vertical movement of the boat lift relative to the object is permitted. The boat lift is connected to the piles by modular units or cube constructs that have a post extending there through. The post has a blade extending from it. The blades are attached at an angle, according to the application, to pile guides that engage piles. The pile guides vertically traverse the piles, permitting the boat lift to move vertically relative to the object, but fixing the horizontal position of the boat lift.

Abstract: A module that is useful for receiving stormwater when buried in permeable media comprises a base from which a plurality of columns extends upwardly, to support two or more different-elevation horizontal plates. Each plate has a plurality of holes, through each of which a column extends. The plates are secured to the columns at their respective elevations by self-acting engaging means comprising a latch, e.g. a peg extending radially from the column, and a mating receiver, e.g., an elastically deflectable plate having a hole that receives the peg. The angular orientation around the column of the self-acting engaging means varies with the plate elevation, so that for example, the first plate is only engageable at the first elevation and the second plate is only engageable at the second elevation. A module is assembled by lifting or lowering each plate along the column lengths until the plate becomes automatically engaged at the particular plate's predetermined elevation.
