  • Patent number: 8911181
    Abstract: A method of inline mixing the exact amount of sodium silicate, catalyst and water to form a grout for injection into underground construction applications in order to eliminate waste of resources. The invention is comprised of a sodium silicate pump assembly and a water and catalyst pump assembly. A metering pump injects a catalyst into the water loop. The sodium silicate pump and the water and catalyst pump discharge lines are merged into one pipeline downstream. The single pipe is connected to a static inline mixer that ensures uniform mixing of all the components. The sodium silicate pump assembly and the water and catalyst pump assembly are hydraulically controlled. This allows an operator to vary the speed of the pump thereby controlling pump discharge.

    Abstract: The system and method to inject grout into a borehole uses a leader comprising opposite fore and aft portions, a pressure-bearing member between the fore and aft portions, and a leader passage extending from a fore opening at the leader fore portion to an aft opening in the leader aft portion. A tube is attached to the leader and connected to the leader aft opening. The leader is inserted into the borehole with the fore portion first. An impelling fluid is injected in the borehole downstream of the pressure-bearing member and exteriorly of the tube, resulting in pressure being applied on the pressure-bearing member and the leader consequently advancing towards the borehole bottom end, the leader carrying the tube with it to deploy the tube in the borehole. Upstream fluid located in the borehole upstream of the pressure-bearing member is evacuated out of the borehole through the leader passage and the tube.

    Abstract: A jet grout injection device is provided for depositing liquid grouting materials using a high pressure jet, that is compact and rapidly assembled and powered by an air compressor for safety considerations. An injection pipe and a high pressure swivel are connected with high pressure steel reinforced hydraulic hose to a grout pump. The high pressure swivel can withstand a range of 0-6000 psi. The injection pipe is rotated using two (02) 45° degree miter gears to transfer the rotation from the gear speed reducer. The air motor receives air from a compressor at a range of 0-100 psi and 0-180 cfm, the air motor 4 provides the torque to the gear speed reducer 3 that converts the rotation of the miter gears 1 to low speed 1-3 rpm with high torque. The device allows access to small rooms in subways, for example, that are buried under various structures or even rivers, that would be excessively expensive to access with a drilling rig on the ground surface, especially in urban environments.

  • Patent number: 7029207
    Abstract: A rapid-set injection system using high-speed jet fluid for forming a pile-shaped solid body in the ground has an injection rod which does not jam in the ground and which has two or three jet nozzles so that the injection rod linearly excavates the target ground. The injection rod has an excavating bit provided at a lower portion of the injection rod to inject downward a fluid to the outside of the injection rod in criss-crossing diagonal directions, with a drill bit coupled to a lower end of the excavating bit, a first agitating unit mounted to an upper end of the excavating bit to inject desired materials to the outside of the injection rod at different levels in different diagonal directions, and a second agitating unit mounted to an upper end of the first agitating unit to horizontally inject air to the outside of the injection rod.

  • Patent number: 6997642
    Abstract: The invention is a system for managing a plurality of areas of interest of a golf course. The system comprises a plurality of electromechanical subsystems and a programmable master control module. Each subsystem provides to a specific area at least one of air under pressure and a partial vacuum. In each area of interest, a local control module is responsive to a directive and to a datum. The local control module is configured to operate the subsystem and is in communication with the programmable master control module. The programmable master control module receives from at least two of the plurality of local control modules information representing a status of the respective specific area to which the local control module is dedicated, and in response to the information and to a command, the programmable master control module issues a directive to the local control module to operate the electromechanical subsystem.

  • Patent number: 6948881
    Abstract: An injection vessel for injecting liquid amendment into contaminated subsurface sediment in ecologically sensitive areas such as shallow water salt marshes, tidal flats, or fresh water wetlands is disclosed. The injection vessel described herein includes a shallow-draft floating platform that has an injection system mounted thereon. The injection system includes an injection grid containing a plurality of injection syringes that receive liquid amendment from a metering pump. The injection grid is lowered such that the output of the injection syringes is within the contaminated sediment. The metering pump provides the liquid amendment to the injection syringes and a fluid path is established that injects the liquid amendment into the contaminated sediment. A propulsion system mounted on the floating platform provides for locomotive and maneuvering power.

  • Patent number: 6939085
    Abstract: A soil aerating machine includes in combination a skid-steer and a basket resembling a loader bucket adapted for attachment to the skid-steer boom. An air pressure tank, an elongate air nozzle pipe, an air hammer, and air control valves for the air nozzle pipe and air hammer are carried within the basket. The elongate air nozzle is attached to the basket using a pivotal bearing surface, which permits controlled motion therebetween. The air hammer is used to assist with the driving of the elongate air nozzle pipe into an earthen medium. A blast of air is then released through the air nozzle pipe into the earth, to loosen and aerate packed or clogged soil. A method of restoring a septic system using the preferred apparatus is also described, as are various alternative apparatus and method steps.

  • Patent number: 6923597
    Abstract: Present in a tail shield (1) for a shield tunneling apparatus are a number of grouting lines (3) that are open to a tail shield end (4) and that can be supplied with filling material for grouting a ring gap (7) with the filling material, such as mortar, for example. In addition, additive material lines (8) that can be supplied with additive material are present, which empty into the grouting lines (3) in an end segment (12) of said grouting lines (3). As a result, an additive material, such as a solidification accelerator, for example, can be added immediately before the mixture is discharged into the ring gap (7), so that the risk of a blockage in the grouting lines (3), which are not accessible in the region of the tail shield end (4), is relatively low.

    Abstract: An apparatus and a process for injecting fluids while prevents backflow are provided. The apparatus comprises a) a hollow core pipe with an open end and a closed end, and containing exit ports in the peripheral wall that are closed when there is no, or low fluid pressure; b) a stationary valve seat, fitted in the pipe; c) an axial sliding plug, disposed to be received in the valve seat where there is no or low fluid pressure thereby closing the exit ports wherein an increase in fluid pressure causes the plug to slide toward the closed end and the opening of the exit ports; and d) a spring held in place between the slidable plug and the closed end, the spring continuously urging the plug in a direction away from the closed end.

  • Patent number: 6561737
    Abstract: This invention relates to a method of post preparation of an injection compound which is useable for injection in for instance existing rock cracks or cracks arisen in connection with blasting away rock during for instance tunnel driving, the injection compound having been subject to a preparation, leading to that the injection compound has been given qualities with regard to shape of the crack formations of the rock. According to the invention, the method is characterized in that the injection compound is subjected to a post preparation in the form of a passage through a wire netting, the size of the mesh and the wire dimension of which being determined from a judgement of the following points: the size of the cracks and the cavities in the rock; the tendency of the injection compound to build up filter cakes; desired rheological qualities of the injection compound. The invention also relates to a device for making the method possible.
