Embodiment

[0064]The underground excavation section of a North Station of a subway line 2 is located under the North Railway Station Road in front of the North Railway Station. The design adopts the "PBA" hole pile method for underground excavation construction, and it needs to be excavated in a small pilot tunnel with a width of 3.5m and a height of 4.5m Construction pile length 17.5m, diameter 1.0m and bored pile with pile length 17.5m, diameter 0.8m. According to the height of the small pilot hole, the maximum processing length of a single-section reinforcement cage shall not exceed 3.0m, and the reinforcement cage of each pile shall be divided into 6 sections and 5 assembly joints. How to complete the steel cage installation quickly and with high quality has become a key issue in construction.

[0065] After research, it was decided to use the mold method to process each section of the steel cage with high precision and assemble it at the opening in the small guide hole.

Abstract

The invention relates to a reinforcement cage and a manufacturing method thereof. The reinforcement cage comprises main reinforcements; the reinforcement cage is divided into a plurality of sections; the main reinforcements, an inner locating stirrup and an outer locating stirrup are arranged in each section of reinforcement cage; the length of the main reinforcements is the same; one ends of the main reinforcements are half wires, and one ends of the reinforcements are full wires; a main reinforcement joint between each section of reinforcement cage is provided with straight thread connectors; and the main reinforcements in each section of reinforcement cage are connected in one-to-one correspondence. The manufacturing method comprises the following steps of: blanking the reinforcements; performing thread rolling on the reinforcement cages; processing the reinforcement cages; storing and delivering the reinforcement cages; splicing the reinforcement cages, preassembling on a spot, putting the processed reinforcement cages end to end according to the sequence of the divided sections into a straight line, sequentially splicing from one end to another end, screwing the connectors one by one, and sequentially arranging the rest reinforcement cages; splicing orifices; and detecting. The invention solves the problem that the reinforcement cage needs to be divided into a plurality of sections for processing and splicing due to the limitation of construction condition. The invention has the characteristics that: the manufacturing method is simple to operate, and the reinforcement cage has high precision and installation rate.

Description

technical field [0001] The invention relates to various cast-in-place pile reinforcement cages in foundation engineering construction and a manufacturing method thereof. Background technique [0002] At present, most of the various large-scale civil engineering projects use piles as the foundation and enclosure structure. Sometimes, due to the constraints of the construction site, technical conditions and construction machinery, it is necessary to divide the reinforcement cage of a pile into multiple sections, and then install it on the site or at the opening To assemble. Welding connection is mostly used at present, the speed is slow, and the welding quality is difficult to guarantee, and the machining accuracy of mechanical joints cannot be guaranteed, the error is large, the main ribs are difficult to correspond one by one, and the gap is large. Contents of the invention [0003] The purpose of the present invention is to provide a reinforcement cage and a manufacturin...
