摘要:
A polymer injection method and apparatus for blocking piping in dikes and dams, uses non-water reacted two-component polymeric material to produce a hydra-insensitive expanding polymer for blocking piping channel. A transferring device is provided to the method, which includes an injection gun, an injector, and a hollow tube, wherein the injection gun connects with an entrance end of the hollow tube through the injector, and an outlet end of the hollow tube inserts into the entrance of the piping channel. The two components of the polymeric material are respectively transported to the injection gun, and are mixed and injected from the gun with high pressure, through the injector, to the hollow tube, and then pushed into the piping channel. Under the chemical reaction, the mixed material expands inside the receiver and becomes foamed solid from liquid, and then the polymer receiver inflates and blocks the piping channel quickly.

A directional fracture grouting method with polymer for seepage control of dikes and dams includes the steps of: arranging a plurality of directional fracture grouting holes at a predetermined distance along the axis of the dike or dam; forming the directional fracture grouting holes by pushing a special drilling tool; placing a hole-sealing grouting pipe and a fracture grouting pipe into each of the directional fracture holes; and injecting including the steps of firstly injecting a small amount of polymer material into the sealing-hole pipe, and secondly injecting predetermined amount of material into the fracture grouting pipe. Under the chemical reaction, the mixed material expands, fractures the soil along the guided directions, and forms a super thin polymer segment. Finally, the polymer segments are overlapped each other, and the seepage control system is constructed inside the dike or dam.

A self-adaption breathable cushion comprises a fixed base and a plurality of self-adaptive units integrated side by side and disposed on the fixed base; each of the adaptive units comprises a strap and an elastic member, the elastic member supports the strap to tension above the fixing, base, when the strap is pressed by the pressure and recessed downwards, the strap pulls the elastic member to be deformed, so that the self-adaptive unit moves downwards in a whole; when the pressure is removed, the elastic member is reset under its own elasticity, and the strap is also reset. The self-adaption breathable cushion can be self-adaptive deformed according to the weight of a human body to be borne, so as to be attached to the human body, making the human body more comfortable, ventilated and breathable, easy to clean, and inexpensive.

A suspending hydraulic pillar includes an oil cylinder, a movable prop, a handle-valve body, a reset spring, a top cover, a bottom seat, a three-way valve, a position-limiting steel wire, and a guide ring. The handle-valve body is provided between a port of the oil cylinder port and the moveable prop. Position-limiting steel wire, a guiding ring, and an oil inlet is located on a lower part of the moveable prop. The three-way valve is provided in the handle-valve body. A dust-prevention ring and a sealing ring are provided between the handle-valve body, the mvoable prop, and the oil cylinder. The handle-valve body is fixed on the oil cylinder by means of a connecting steel wire. The handle-valve body does not move up and down as the movable prop telescopically extends or contracts. The suspending hydraulic has good stability, high strength and supporting force, good sealing, and high anti-erosive capability.
