[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product - high-pressure pump high-pressure reciprocating pump]: (1) high-pressure reciprocating pump is suitable for: cleaning pumps, process pumps, copper pump urea, ammonia-based liquid formic acid dimethyl pump Food quality pumps, detergent slurry pump, ammonia pump, slurry pump, five sodium pump, booster pumps, injection pumps, descaling pump, pump, rust pumps, high pressure water atomizing assembly types: There are lying , fixed, mobile. Transmission type: a motor, diesel engines, gear box, pulleys, magnetic speed control, frequency control. Each species of pumps are equipped with safety relief valve, pump pressure can be adjusted. Soft Rock Tunnel horizontal jet grouting method in soft rock tunnel construction method of horizontal rotary jet large pile pile diameter soft ground treatment, comprising: a horizontal rotary jet drilling rig having a predetermined depth and diameter of the first type drilling; the completion of the first Injecting a type of drilling equipment after the previously prepared aqueous slurry supplied to the first type drilling end of Pier Soft Foundation pile, so as to exit the first type drill borehole drilling along a first type holes are formed from the inside out first type of pile; use the ejector apparatus length of the first type drilling depth previously prepared in the same first-shaped stiffening member is inserted into the first type of pile until the first type in a first type drilling the end of the bore; synchronized around the movable body by controlling the first bracket and the second supporting frame longitudinal axis to change the position of the spray boom of construction, to construct a monolithic curtain system; by synchronous control of the first support carrier and a second carriage lift height to narrow the horizontal rotary jet rig construction radius, so that inside the tunnel to be formed to form an array-like stable system.
