Construction method of rapidly mounting and dismantling hanging die system for integrally pouring walling crib of inspection well

Abstract

The invention relates to a construction method of rapidly mounting and dismantling a hanging die system for integrally pouring the walling crib of an inspection well. The construction method comprisesthe following main construction steps: mounting a hanging die structure, assembling a bottom die, pouring the walling crib and a basement layer, and dismantling the hanging die structure. The hangingdie structure in the unfolded state is fixed on a cushion block on the circumference of the well; the elevation of a horizontal support rod is adjusted, and the bottom die meshed with the horizontalsupport rod is mounted on the horizontal support rod to further lower a side die cylinder so as to embed and press the side die cylinder in a limiting groove; then, the basement layer and the wallingcrib are poured, after the concrete reaches the design strength, the side die cylinder is spun upwards, a screw rod is lowered, and the bottom die is taken out of a wellhead one by one; and finally, the hanging die structure is adjusted to the folded state, a bolt is removed and the hanging die structure is dismantled. According to the construction method, installation and dismantling are convenient, the construction efficiency is high, recycling is realized, the integrity of the walling crib under construction and the basement layer is high, the problems that the working procedures are many,the consumed time is long, and the joint part of the road surface of the walling crib is likely to crack existing in the construction method of the traditional inspection wellhead department are solved, and the economic and technical benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and in particular relates to a construction method for rapid installation and disassembly of a hanging formwork system for integral pouring of an inspection well circle. Background technique [0002] The traditional inspection well head construction method is to prefabricate a concrete well circle with a reserved hole in advance, then install the inspection well cover on the well circle, and then pour the concrete ground. This construction method has the following disadvantages: first, the well circle and the surrounding ground are poured separately, which makes it difficult to form an integral body with the surrounding ground, and easily produces floor cracks, resulting in quality problems, reducing the service life of the road surface, and affecting driving safety; second, Most of the well circles are self-prefabricated, with different pouring thicknesses and sizes. The installation process...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of many procedures, long time-consuming, easy cracking at the joint between the road surface and the well ring, poor integrity and durability of the road surface, etc. in the traditional construction method of the inspection well head, and proposes a fast method for integral pouring of the inspection well ring. Install and disassemble the hanging formwork system to facilitate simultaneous pouring of pavement and well circle
