Embodiment Construction

[0029] Such as Figure 4 As shown, in this embodiment, the length*width of the cross-section of the cable trench 18 is 50cm*55cm, and one side of the cable trench 18 is a side ditch 19 .

[0030] Such as Figure 1-3 As shown, a tunnel cable trench forming device includes a rail truss car and a formwork system. Wherein the track truss car is installed on the surface of the subgrade 17 which has been constructed, and the track installed on the surface of the subgrade is used to control the elevation and line shape of the cable trench.

[0031] specifically,

[0032] The rail truss car includes a track 2 and a truss car steel structure. The track 2 is placed on the sleeper 1, and the track 2 is provided with a traveling wheel 3, which is installed below the steel structure of the truss car. The traveling wheel 3 is connected to the traveling motor 4, and the traveling motor 4 drives the steel structure of the truss car to advance. The steel structure of the truss car includes...

Abstract

Provided are a tunnel cable duct forming device and method. The tunnel cable duct forming device mainly comprises a device body, and the device body comprises a rail crane and a template system. The rail carne comprises a crane steel structure, and the crane steel structure is arranged on rails through walking wheels. The template system comprises a template assembly and a driving assembly, the template assembly comprises surface plates inside and outside, the surface plates inside and outside are fixed to supporting mechanisms inside and outside respectively, and the surface plates inside andoutside and the rail crane are connected into a whole through a connecting beam. The driving assembly comprises a first hydraulic oil cylinder and a second hydraulic oil cylinder, the first hydraulicoil cylinder and the second hydraulic oil cylinder drive the two opposite inner surface plates and the two opposite outer surface plates to be close or far away respectively, and pressing or demoulding is achieved. According to the tunnel cable duct forming device and method, the cost can be reduced, and the construction quality can be guaranteed.

Description

technical field [0001] The invention relates to the field of cable trench construction, in particular to a tunnel cable trench forming device and a forming method. Background technique [0002] In the construction of tunnel concrete cable trench, the traditional construction method is to use the shaped formwork to erect and dismantle the formwork. After the construction is completed, the next section will be constructed after the demolition. This method has a large workload, requires more materials, equipment and labor, has a long construction period, high cost, and narrow cable trench space. The formwork is not easy to reinforce, and it is easy to cause the formwork to move, and the construction quality cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tunnel cable trench forming device and forming method, which solves the common problem that the quality of cable trench construction is diff...
