Abstract

The invention relates to a method for constructing the concrete screw post of screw drilling rod central pump, and a relative screw producer, wherein it can solve the problems as high cost and hard synchronization; it comprises: first using the long screw driller to drill the hole to preset length; then the hydraulic jack extends out the screw producer to rotate reversely and lift the drilling rod, while filling over-flow concrete into the hollowing drilling rod; then drawing out the drilling rod to insert into the steel bar cage.

Description

Technical field:

[0001] The invention relates to a construction method and a machine tool for building pile foundations. Background technique:

[0002] At present, there are many construction methods for concrete pouring piles in building construction. For example, the method of superfluid concrete pouring into piles cannot form threads in the pouring piles, which has the disadvantages of wasting concrete and high cost. However, the existing threaded pile construction The cost of the machine tool is high, the synchronization problem is difficult to solve, it is not easy to form threads, and it is difficult to succeed. Invention content:

[0003] The purpose of the present invention is to provide a construction method and a screw thread manufacturing device for auger rod center pumping superfluid concrete threaded piles which can improve the bearing capacity of piles and reduce construction costs.

[0004] Above-mentioned purpose realizes by following technical scheme: ...
