[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] triple tube rotary jet grouting materials and grouting material formulation requirements as the main material in cement sealing curtain pile, and adding different additives, may have a quick-setting early strong, frost and other properties. The type of cement slurry more, with different geological conditions and use, the slurry material vary. 1, high strength, suitable for consolidation of the body above the average strength of 20MPa engineering, high strength cement (not less than the strength level 42.5); add high-performance diffusion agent (such as intensity level of ordinary portland cement 32.5 NNO, triethanolamine, sodium nitrite, sodium silicate, etc.) and inorganic salts. 2, fillers, suitable for less demanding early strength works to reduce project cost. Commonly used fillers are fly ash, slag, etc. 3, antifreeze type, suitable for controlling frost heaving of the project. Commonly used additives are: zeolite powder, NNO, triethanolamine and sodium nitrite. Note should not use pozzolana cement triple tube sealing curtain pile, preferably with ordinary cement, slag cement grade can also be used. The company also produces high-pressure pumps and accessories: GZB-40C series of high-pressure injection pump and various sets of parts (seat, valve plate sealing curtain Buying pile, limit sets, a variety of seals sealing curtain pile production Manufacturers, O-rings, tower spring, stuffing, diaphragm, bottom cover, sleeve, core rod, copper gaskets, copper ring series: pressure rings, grommets, supporting ring, locking mother, support ring, plunger , the oil guide sleeve. and 35 pump accessories) The company's patented seat-strong, with easy disassembly, economical and durable than the original seat life increased by 3 times. Soft Rock Tunnel horizontal jet grouting method in soft rock tunnel horizontal jet grouting method comprising: using horizontal drilling rigs Jet has a predetermined depth and diameter of the first type drilling; after the completion of the first type drilling Grouting the device will end the previously prepared water is supplied to the first type of drilling mud, so as to exit the first type drill borehole drilling along the first type form a first type of pile from the inside out; with ejector means the length of the previously prepared drilling depth and the first type the same first-shaped stiffening member is inserted into the pile until the end of the first type first type borehole drilling along a first type; by controlling the first bracket and second support frame sync around the longitudinal axis of the movable body is rotated to change the position of the spray boom of construction, to construct a monolithic curtain system; by synchronous control of the first carriage and the second carriage lift height to reduce the level of Jet Construction radius rig, so to be formed inside the tunnel forming an array stabilization system.
