Filling pile concrete guide pipe assembling and disassembling device and construction method thereof

Abstract

The invention relates to a filling pile concrete guide pipe assembling and disassembling device which comprises a stand and a hoisting system. The stand is formed by connecting a base, a door frame and two slant struts; the door frame is connected with one side of the base; the lower ends of the two slant struts are connected with the other side of the base, and the upper ends of the two slant struts are connected with the upper parts of two door posts of the door frame; the hoisting system comprises a guide wheel, a hoisting machine, a steel wire rope and a pulley hoisting hook; the guide wheel is arranged in the center of the door frame; the hoisting machine is arranged at the middle part of the base and between the two slant struts; the steel wire rope is wound on the hoisting machine and passes by the guide wheel; and the pulley hoisting hook is used for assembling and disassembling a concrete guide pipe or hopper and connected with the steel wire rope. In the invention, the restriction of an automobile hoister on a filling pile extracting guide pipe is eliminated, the filling pile concrete guide pipe assembling and disassembling device has high efficiency, and the drilling and the filling can be carried out rapidly and continuously on the construction site. The filling pile concrete guide pipe assembling and disassembling device is used for manual hoisting based on the lever principle, and has the characteristics of simple structure and convenience for processing, can move flexibly, occupies less construction site, can be reutilized and can reduce the engineering cost; moreover the machine team is saved.

Description

technical field [0001] The invention relates to a device for installing and dismantling concrete conduits of cast-in-place piles and a construction method thereof. Background technique [0002] In the process of pile concrete pouring, the traditional positive and reverse circulation drilling machine can integrate drilling and pouring, that is, it does not need to invest in other auxiliary equipment for pouring, but directly uses its own hoist, etc. Relevant supporting facilities are used to perfuse and withdraw the catheter. However, the disadvantages of forward and reverse circulation drilling machines are that the on-site construction cannot be carried out continuously, and the pile-forming speed is slow, so rotary drilling machines have been more and more used recently. The characteristic of the rotary drilling rig is that the pile-forming speed is fast, but the drilling and pouring are separated, and there must be supporting equipment for pouring and pulling out the con...

Problems solved by technology

However, the disadvantages of forward and reverse circulation drilling machines are that the on-site construction cannot be carried out continuously, and the pile forming speed is slow, so the rotary drilling machine has been used more and more recently.

The characteristic of the rotary drilling rig is that the pile-forming speed is fast, but the drilling and pouring are separated, and there must be supporting equipment for pouring and pulling out the conduit. Therefore, in ordinary construction, a truck crane above 16T is often used for combined pouring. , this method is inflexible in operation, high in cost, and occupies a large construction site
