Shanghai Strong foundation CSM construction pile machine can be used in the construction of weathered rock, the construction depth can reach more than 60m, has the advantages of strong formation adaptability, fast construction speed, high wall quality, especially suitable for use in complex strata.
Shanghai Strong foundationCSMConstruction method pile machine can be in the construction of weathered rock, construction depth up to60mThe above,It has the advantages of strong formation adaptability, fast construction speed and high wall quality, especially suitable for use in complex strata.
1, obstacle clearing
Because the enclosure requires continuous construction, the underground obstacles in the enclosure construction area should be detected and cleared before construction to ensure smooth construction.
2, measuring the line
According to the owner to provide coordinate reference point, general layout drawing, enclosure construction drawing. The project department will release the pile position control line according to the drawing, set up temporary control piles, complete the technical review list, and submit it to the general contractor and the supervisor for acceptance after the company's professional personnel check it correctly.
3, excavate trench
According to the foundation pit perimeter0.4m3The dredge excavates the trench, and the trench size is1000×1200mm,The underground obstacles should be removed, and the soil in trench excavation should be treated in time to ensure the normal construction of double-wheel milling soil-cement mixing wall.
4,CSMThe working machine is in position
Under the unified command of the shift monitor, the piling machine is placed in place, and the steel plate is laid under the piling machine. Before moving, see clearly the situation of the upper, lower, left and right aspects, and remove obstacles in time. After moving, check the positioning situation and correct in time. The working machine should be smooth and straight, and the theodolite or line hammer should be used to observe to ensure the verticality of the drill; The positioning deviation of soil-cement mixing wall should be less than50mm. The horizontal deviation of the wall shall not exceed20mm, the depth shall not be less than the design wall depth and shall not be greater than the wall depth100mm, the vertical deviation of the wall body shall not exceed1/400.
