The invention provides a foundation pile reinforcement method, which belongs to the technical field of building construction methods. Drill a pre-filling hole with a diameter larger than that of the molded pipe at the design position; insert the reaming auxiliary tool in the pre-filled hole; put the explosive component from the upper opening of the molded tube, and the explosive component includes a number of explosive packs connected in series; Ignite the lead wire of the explosive package at the top of the shaped tube to form an enlarged diameter hole at the bottom of the prefilled hole; rotate the shaped tube, adjust the position of the spoke, and blast again according to the above steps to increase the diameter of the enlarged hole; After the diameter of the hole reaches the design size, place a reinforcement cage in the pre-filled hole, pour concrete, and vibrate the concrete to fill the diameter-expanding hole and the inside and outside of the reinforcement cage. ground piles. The invention has the advantages of high strength, high stability and the like.
Description
A method of strengthening the foundation with piles technical field The invention belongs to the technical field of building construction methods, and relates to a kind of foundation pile reinforcement method. Background technique The treatment method of building foundation has a lot of, wherein, concrete piling is a common foundation reinforcement method, undertakes construction. The beam-column structure of the building can enhance the bearing capacity and stability of the building. [0003] The cast-in-place pile is directly formed by opening a hole in the designed pile position, then adding a reinforcement cage in the hole, and then pouring concrete. for In order to further enhance the stability and bearing strength of the cast-in-place pile, there is a construction method of blasting the cast-in-place pile in the prior art. In the blasting pile-filling construction method, the explosive pack is first put into the bottom of the pile hole, in order to avoid the gra...
