Problems solved by technology

[0003] In the prior art, the retaining piles installed vertically and the crown beams installed horizontally are cast on site. Since the external dimensions of the crown beams are usually relatively thick and have a certain weight, it is necessary to require the retaining piles to be solidified after construction. Only then can the pouring construction of the crown and beam be carried out. In this way, there are technical problems of relatively long construction period and general construction quality

Embodiment Construction

[0021] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0022] like figure 1 and 2 As shown, a method for constructing a retaining pile based on a tenon-and-mortise structure comprises the following steps:

[0023] Step 1: The vertical retaining piles 1 of the construction supporting piles are poured on site by means of artificial digging piles and mechanical hole forming, and the tenon 3 shape is poured on the top of the retaining piles 1; The transverse crown beam 2 of the pile guard, the crown beam 2 is formed with a socket 4 that matches the tenon. In this implementation, the tenon 3 is preferably cast into a trapezoidal table structure, and the lower part of the socket 4 is constructed into a trapezoidal hole shape.

[0024] In step 1, the pouring of the retaining pile 1 and the pouring of the tenon 1 may be completed in one pouring construction, or may be constructed in two steps. Regardless of t...

Abstract

The invention discloses a support pile construction method based on a tenon-and-mortise structure, which comprises the following steps of: 1, pouring a vertical retaining pile of a construction support pile, and pouring the top of the retaining pile into a tenon shape; meanwhile, a transverse top beam of the support pile is prefabricated through a prefabricated part technology, and a mortise connector matched with the tenon in shape is formed in the top beam; secondly, prefabricated top beams are hoisted to the tops of the retaining piles, a single top beam stretches across at least two retaining piles, and mortise connectors of the top beams are buckled on tenons at the top ends of the retaining piles; and 3, plugging the mortise joint from the upper surface of the crown beam. The construction method has the beneficial effects that the support pile crown beam is made of the prefabricated parts, the crown beam can be prefabricated and manufactured synchronously during retaining pile construction, then assembly and connection are conducted through the mortise and tenon joint process, and the technical advantages of being short in construction period, high in construction efficiency and high in support pile forming quality are achieved.

Description

technical field [0001] The invention relates to supporting pile construction, in particular to a supporting pile construction method based on a tenon-and-mortise structure. Background technique [0002] With the large-scale increase of social infrastructure and the continuous update and iteration of engineering construction technology, the proportion of slope treatment and foundation pit engineering is increasing. As a common supporting structure, supporting piles can be widely used For slope treatment and foundation pit engineering. [0003] In the prior art, the vertically arranged retaining piles and the horizontally arranged crown beams of the supporting piles are both cast on site. Since the external dimensions of the crown beams are usually thick and large and have a certain weight, it is necessary to require the retaining piles to be solidified after construction. Only then can the pouring construction of the crown beams be carried out. As a result, there are technic...
