[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product - high-pressure pump] high pressure reciprocating pump features: High-pressure reciprocating pump pressure should generally be between 10MPa ~ 100MPa. It belongs to a positive displacement pump, with the working chamber cyclical changes in volume to achieve the purpose of transmission fluid; the original motivation of the mechanical energy by pressure feed pump directly into fluid energy; pump capacity depends only on changes in the value of the working volume of the chamber and Changes in the number of times per unit time, theoretically independent of discharge pressure. Reciprocating pump is by means of a hydraulic cylinder piston reciprocates in the working chamber (or through the diaphragm, bellows and other flexible element in the periodic elastic deformation of the working chamber) to the working chamber volume to generate a periodic change. Structurally, the reciprocating pump working chamber is from the outside world by means of sealing means sealing curtain triple pipe pile, through valve (suction and discharge valves) and the line of communication or closed. High Pressure Jet Roofbolter and high pressure jet grouting construction method in geotechnical engineering anchor a high pressure jet grouting anchor construction machinery and high-pressure jet grouting method anchors. Loose sand in the river and waterfront phase phase of the silt layer, not construction anchor pile sealing curtain factory, because: gravel rich in confined water, anchor into the hole hard, water will return loop cuff technique will produce piping, Chung sand, gushing water, ground subsidence and other accidents pile sealing curtain curtain wall construction, silt-free anchoring force, but to use high cost, long duration, for the inner city have supported method dirty qi. The present invention is to provide a new high-pressure jet grouting bolt rig, bolt rig the pressure rotating jet can vertical, horizontal, diagonal full range of construction Jet anchor piles and anti-floating, tension bolt, the high pressure Churning Roofbolter may be applied not only bigger and straight rotary jet cement anchor bolt head can expand construction. The above object of the present invention is to provide a new kind of high pressure jet grouting bolt rig, bolt high pressure jet grouting construction method to solve the soft soil of silt layer construction without anchoring force can not be the problem, it will be free, in loose gravel soil, in order to lower a hole tendon using casing up method, water will return cycle produces sudden Chung, Chung sand, gushing water, ground subsidence and other accidents.
