Problems solved by technology

[0003] However, when the project involves super-long foundation piles, the cap is large, the upper structure is basically a long-span, and the large cross-section of the structure itself requires high safety requirements.
The design requires that the reinforcement be inserted into the pile foundation. Due to the depth of the reinforcement, the large diameter of the reinforcement, and the screw connection, the construction is difficult and the positioning requirements are particularly high. The positioning construction of the super-long foundation pile is particularly important. In the actual construction process, there are no effective solutions

Embodiment 1

[0046] Such as Figures 1 to 5 As shown, a super-long foundation pile foundation insertion reinforcement positioning construction method requires that the rotary excavation pile hole 13 is perpendicular to the ground level 12, the insertion reinforcement 14 is parallel to the rotary excavation pile hole 13 and inserted into the pile reinforcement 15, and the construction is carried out according to the following steps:

[0047] Step 1. Determine the length and quantity of ribs

[0048] A1. Make statistics on the need for reinforcement piles on site;

[0049] A2. Calculate the depth of the reinforcement according to the elevation of the top of the foundation pile;

[0050] A3. Number the foundation piles and determine the length and quantity of bars that need to be inserted;

[0051] Step 2: Fabrication of the rib-fixing bracket

[0052] According to the requirements of inserting ribs, make corresponding inserting rib fixing brackets. The inserting rib fixing brackets includ...

Abstract

The invention discloses a positioning construction method for foundation joint bars of a super long foundation pile and belongs to the field of joint bar construction of foundation piles in constructional engineering. The positioning construction method comprises the steps that the length and quantity of the joint bars are determined; fixing brackets of the joint bars are manufactured; the fixing brackets of the joint bars are mounted; the fixing brackets of the joint bars are fixed; the center lines of the joint bars are measured and positioned; the joint bars are constructed; elevations of the joint bars are controlled; the joint bars are fixed; and the joint bars are retested. According to the construction method, the fixing brackets and manufacturing, mounting and fixing working around the fixing brackets are added, the effects of positioning and constructing are played in actual operation, the positioning effect is obvious, and the quality, efficiency and safety in the construction process are improved.

Description

technical field [0001] The invention belongs to the field of foundation pile insertion reinforcement construction in construction engineering, and in particular relates to a super-long foundation pile foundation insertion reinforcement positioning construction method. Background technique [0002] With the development of the construction industry, the improvement of building functions and the improvement of building safety, the requirements for structural construction are getting higher and higher. Usually, the general structure uses pile foundations as the main bearing structure load, and pile foundations and caps as force transmission. For the structural body, it is convenient and fast to insert reinforcement inside the cap, and the construction process of inserting reinforcement for ordinary foundation piles does not have high requirements for positioning. [0003] However, when the project involves super-long foundation piles, the caps are large, the superstructure is ba...
