Integral casting construction method for cable trench of highway tunnel water ditch

Abstract

The invention relates to an integral casting construction method for a cable trench of a highway tunnel water ditch. The method comprises the following steps of in the construction process of the cable trench of the tunnel water ditch, firstly, prefabricating a movable bracket structure and a matched shaping formwork, and suspending the shaping formwork through a first screw rod and a second screw rod; moving and adjusting the shaping formwork to the preset position by the movable bracket, fixing the relative position between the shaping formworks and the relative position between the corresponding shaping formwork and a bracket structure by a first support groove, a second support groove and a steel channel frame, fixing the formworks, and then casting the structure; after forming and demoulding of the structure, moving a whole form frame to the concrete casting position of the next form through manual pushing or mechanical traction, and repeating the steps to complete the casting. The integral casting construction method has the advantages that a new construction method for the integral movement of the form frame system of the cable trench of the tunnel water ditch is provided, a movement and suspension system is updated, the process updateability and the operability are higher, the flatness and line shape of the structure are more attractive, and the one-time vertical form casting and forming can be realized.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to an integral pouring construction method for a highway tunnel water ditch cable groove. Background technique [0002] In the prior art, the construction of tunnel gutters and cable troughs is done by pouring concrete in stages, and the formwork is supported multiple times. The geometric dimensions and line types of trenches and cable troughs will reduce the quality of the project. [0003] The construction of the traditional tunnel trench cable trough is constructed in sections using small combined steel molds. The construction process includes assembly, reinforcement, pouring, disassembly, transition, cleaning and oiling. The process is complicated, the cycle time is long, and there are many reinforcement supports. The performance is poor, the appearance quality is difficult to control, and the construction cost of the formwork project is high. [0004] In view of the above-m...
