Ditch cable trough construction trolley and its construction method, cable formwork device for tunnel

Abstract

The invention provides a ditch cable trough construction trolley, a construction method thereof and a cable die set device for a tunnel. The cable die set device comprises a first oil cylinder and a cable die set. The end of the first oil cylinder is hinged to the cable die set. The cable die set comprises a positioning clamp, a positioning set square, an adjusting nut and a lead angle pipe, wherein the positioning clamp is fixedly connected with the cable die set and provided with a through hole and a through groove; the lead angle pipe comprises a positioning part and a connecting part connected with the positioning part; the positioning part penetrates through the through hole and is fixedly connected with the adjusting nut; and the positioning set square penetrates through the through groove and is connected between the lead angle pipe and the positioning clamp in an adjacent mode. The invention further provides the ditch cable trough construction trolley provided with the cable die set and the construction method of the construction trolley. Both the cable die set device and the construction trolley have the advantages that the construction quality is high, and the demolding time is short; and in addition, by applying the construction method of the construction trolley, the construction precision of a tunnel cable trough can be improved, the demolding time is shortened, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a cable formwork device for a tunnel, a ditch cable trough construction trolley equipped with the cable formwork device, and a construction method of the construction trolley. Background technique [0002] Tunnel gutter cable trench is an auxiliary project of tunnel construction, generally the last process of tunnel construction, and construction can only be organized in the middle and late stages of tunnel construction, so there are common problems such as large construction volume and tight construction period. At the same time, there are long-term problems such as poor linearity, many construction joints, and difficult construction joints in the construction of concrete for water trenches and cable trenches. Moreover, since the trenches and cable trenches are located on both sides of the tunnel, their appearance quality will directly affect the overall standardizati...

AI Technical Summary

Problems solved by technology

However, since the formwork of the gutter cable trough is a non-load-bearing plate, and all of them adopt an overall closed U-shaped formwork structure, the demoulding method of lifting the U-shaped formwork vertically must overcome the atmospheric pressure caused by airtightness

When the concrete is not completely solidified or the strength is not enough, lifting the U-shaped plate for demoulding will cause large-scale damage to the concrete structure of the trench cable trench, which will cause the existing construction trolley of the trench cable trench to be affected by the concrete strength factor in the demoulding process time. impact, the demoulding time also needs at least 14 hours

Although the construction time of the existing trench cable trough construction trolley is greatly shortened compared with the traditional construction, the overall construction time is still relatively long
