Construction method of rapid installation and dismantling of hanging formwork system for integral pouring of inspection well circle

Abstract

The invention relates to a construction method for quickly installing and dismantling a hanging formwork system for integral pouring of a well circle of an inspection well. The main construction steps include: installing a hanging formwork structure, assembling a bottom form, pouring a well circle and a base, and removing the hanging formwork structure. The present invention fixes the suspended formwork structure in the unfolded state on the cushion block around the well; then adjusts the elevation of the horizontal struts and installs the interlocking bottom form on it, and further lowers the side formwork to make it embedded in the limit groove Middle; then pour the base and the well ring, and after the concrete reaches the design strength, turn up the side formwork, lower the screw, and take out the bottom form piece by piece from the wellhead; finally adjust the suspension formwork structure to the retracted state, release the bolts and remove the suspension Modular structure. The invention has the advantages of convenient installation and disassembly, high construction efficiency, recyclable utilization, good integrity of the construction well ring and the base layer, and overcomes the problems of many procedures, long time consumption, and easy cracking at the junction of the road surface and the well ring in the traditional construction method of inspecting the well head. , 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...
