320 tons of cement pipe jacking machine

HBXJS-B-320T / 1 cement pipe jacking machine structure and description: Hydraulic cement pipe jacking machine designed for large pipe jacking engineering design, generally used in cement pipe crossings, house building translation, construction of sewers and 2.0-3.0 Highway river crossing heat pipes and other engineering a host part: 320 tons of large diameter using a hydraulic cylinder, shape diameter 426MM, total length 1520MM, piston diameter 360MM, weight of 1.25 tonnes of hydraulic pump station unit :(. a motor pump station), motor with 5.5 kilowatts of three-phase induction motor, speed 1470- rev / min, 380 V 29.9 Safety, pressure gauge, oil pressure gauge, pressure relief valve (plate), gear pumps update 10MCY14 type plunger pumps, pressure can be up to 25Mpa, pilot switch (automatic valve), two-way Third tubing The top block piece. (vertical top) between the fuel tank and cement pipe to use. IV. stopper piece. (horizontal top ) stand in the front cement pipes, cement pipes to prevent the contact between the top block damage. V. unearthed a car unearthed with the tube. VI. Host Dimension (m) 1.52X0.5X0.5 VII. Pumping Dimensions (mm) 600X800X1150 eight host quality (kg) 1250 IX. Pumping mass (kg) 300 X. jacking force (kn) 300-500 XI. Maximum working pressure (mpa) 31.5 XII. Single carried away top .. (m) 1.1 / 1.0 thirteen single lay length (m) 50-70 fourteen pre-construction preparation work: excavation work before construction pit select the host into the work pit, select the excavation pit on After the success of the construction is critical. 1. First mastery construction section of underground facilities and pipelines obstacle in the selection jacking pit excavation work and work, such as (cable, cable, gas pipelines, heat pipes, sewers, water pipes The depth and location) at the same time to know whether the backfill the road obstructions garbage, stones, foundation, etc. 2. Determine grasp to understand the subsurface, before determining a route and location of the construction work of the pit to prevent the construction of top and back drag encountered obstacles damaged machinery and accessories sixteen construction methods: 1. Press the model dimensions first dug pit operation, after jail support, operations in case of soft soil pit or sand layer is required to lay around support to protect the machine and personnel safety. 2. After the first pit dug job track into the pit work, looking for the positive direction along the construction route, leveled. 3. Place the top of the machine into operation smoothly hanging pit, on the track. 4. The diameter required track direction forward dig earth excavated, the length of 2.5M-2.8M, has been resolved ahead unearthed. Dig soil can decide the length of the master according to the terrain and soil conditions. 5. smooth cement pipe hanging into the pit jobs . 6. The stopper cross on the back-end cross-cement pipes at the top position. 7. intact soil where, generally cement pipe jacking be divided into two, with the top block (vertical top) twice per performance of one meter. 8. Start the high pressure pump station, to be on top of the cylinder with the stopper force, checking After the support is solid, determined after a solid support, you can forward the cement pipe jacking. If silt soil, remove and then forward into the top, and so on until completed.
