Green dismantling construction method combining concrete support static crush and splitting method
The invention relates to a green dismantling construction method combining concrete support static crush and a splitting method. The construction method comprises the main steps that 1, embedded parts are installed, and holes are buried; 2, concrete pouring is conducted on supports; 3, a dismantling platform is erected; 4, support fastening is conducted; 5, a hang rope of a crane is made to enter into lifting points; 6 static crush is conducted; 7, concrete is peeled through the splitting method; 8, reinforcing steel bars are cut through flame; 9, the supports are lifted away in sections. Reinforcing steel bar sleeves are arranged on waist bars and longitudinal bars at the end before concrete pouring is conducted on the concrete support, PVC embedded pipes are embedded in the end and the middle of the concrete support, and embedded screws are arranged at the end of the concrete support; after the concrete reaches the prospected strength, the end of the concrete support is stuck with reinforcing steel plates and fixed through bolts, prestress steel bars are arranged in the concrete support, and the prestress steel bars are tensioned tightly. The green dismantling construction method combining the concrete support static crush and the splitting method has the advantages of being easy to operate and small in interference to surroundings, and the good economical and technical benefit is achieved.
