Ship lock head side pier combined template and installation method

Abstract

The invention discloses a ship lock head side pier combined template. The ship lock head side pier combined template comprises a cantilever hanging frame and truss templates, wherein the cantilever hanging frame comprises a supporting triangular frame and a pair of adjustable supporting rods; and one end of a horizontal rod of the supporting triangular frame is fixed on a pre-buried climbing anchor cone which is poured with concrete. The upper and lower ends of the adjustable supporting rods are hinged with the middle part of a truss and the other end of the horizontal rod respectively; and the lower ends of the truss templates are vertically arranged at one end of the supporting triangular frame through a truss template position adjusting and fixing mechanism. An installation method disclosed by the invention comprises the following steps of: 1) mounting the supporting triangular frame; 2) mounting the truss templates at one end of the supporting triangular frame; 3) mounting the adjustable supporting rods; 4) fixing the truss templates; 5) mounting the second truss template and locking upper openings of one group of two truss templates; and 6) connecting the plurality of groups of truss templates to form a sealed framework template structure. According to the ship lock head side pier combined template, the self weight of the combined template is alleviated, the manufacturing cost is reduced, the bending strength and rigidity of the truss templates are improved and the safety of the ship lock head side pier combined template is improved.

Description

technical field [0001] The invention relates to a wall formwork of cast-in-place reinforced concrete, in particular to a combined formwork and an installation method for building the head and side pier of a ship lock, belonging to the technical field of hydraulic engineering construction. Background technique [0002] The ship lock is a key hydraulic structure for lifting ships or fleets in order to overcome the water level difference in the waterway transportation channel. Only by opening and closing the lock gate to adjust the water level can the channel maintain normal navigation. The cross-section of the front side pier of the ship lock formed by pouring reinforced concrete is in the shape of a trough, including the bottom plate and the side pier structures at both ends of the bottom plate. The formwork must be installed before the reinforced concrete is poured. The formwork structure and installation quality have a great influence on the construction quality and constru...

AI Technical Summary

Problems solved by technology

[0003] The formwork is usually welded by section steel and steel plate. In order to have sufficient strength and rigidity, the existing formwork for side pier trusses at gate head uses larger section steel and steel plate to increase its flexural section modulus and reduce its Stress value, but increased the self-weight and steel consumption of the head side pier formwork, increased the construction cost

[0004] There is no operating platform at the lower part of the formwork of the existing gate side pier. When the concrete of the gate side pier is poured in multiple layers, since there is no support point at the bottom of the formwork and no operating platform, it is very difficult for construction workers to support the formwork, and there are greater security risk
