Embodiment 1

[0075] see Figure 1 to Figure 4, an assembled cement prefabricated double-layer cable trench, including a trench base 1 and a cover plate 2, the cover plate 2 is arranged on the trench base 1, and the trench base 1 is a concrete prefabricated part; the trench The groove base 1 comprises a groove bottom plate 11, a groove back wall 12, a first groove wall 13, a second groove wall 14, a groove face wall 15 and a groove top plate 16, the groove back wall 12, the first groove wall The bottoms of the groove wall 13, the second groove wall 14 and the groove wall 15 are all fixedly connected with the top surface of the groove bottom plate 11, and the tops of the second groove wall 14 and the groove wall 15 are connected with the groove The bottom of the top plate 16 is fixedly connected; a closed cable groove 3 is formed between the groove bottom plate 11, the second groove wall 14, the groove surface wall 15 and the groove top plate 16, and the groove on the groove bottom plate 11 ...

Embodiment 2

[0083] Embodiment 2 is basically the same as Embodiment 1 and its difference is:

[0084] The front tenon 71 , the rear tenon 73 and the upper tenon 75 are located on the same side of the groove base 1 .

Embodiment 3

[0086] Embodiment 3 is basically the same as Embodiment 1 and its difference is:

[0087] Described 3rd step: closing mold comprises the following steps:

[0088] a, the cage frame that steel bar is made is placed on the outer mold 81, the cage frame support is installed on the bottom of the cage frame, after placing, there is no direct contact between the cage frame and the outer mold 81;

[0089] b. After placing the cage, close and lock the front formwork 82, rear formwork 83, convex formwork 84 and notch formwork 85, insert the mandrel 86 and adjust the mandrel 86 to make it tighter. At this time, the mold clamping is completed .

Abstract

The invention provides an assembly type cement prefabricated double-layer cable trench and a manufacturing method thereof. The assembly type cement prefabricated double-layer cable trench comprises a trench base body and a cover plate. The cover plate is arranged on the trench base body. The trench base body is a concrete prefabricated piece. The trench base body comprises a trench bottom plate, a trench back wall, a first trench wall, a second trench wall, a trench face wall and a trench top plate. The bottom of the trench back wall, the bottom of the first trench wall, the bottom of the second trench wall and the bottom of the trench face wall are fixedly connected with the top face of the trench bottom plate. The top of the second trench wall and the top of the trench face wall are fixedly connected with the bottom of the trench top plate. A sealed cable groove is formed among the trench bottom plate, the second trench wall, the trench face wall and the trench top plate. A first cable duct is formed between the trench back wall and the first trench wall on the trench bottom plate. A second cable duct is formed between the first trench wall and the second trench wall on the trench bottom plate. By means of the design, the assembly type cement prefabricated double-layer cable trench is not only steady in structure, long in service life, but also simple in mounting and manufacturing method and high in practicability.

Description

technical field [0001] The invention relates to a cement prefabricated trench structure, in particular to an assembled cement prefabricated double-layer cable trench and a manufacturing method thereof, which is particularly suitable for speeding up the laying of the cable trench and realizing the classified arrangement of cables. Background technique [0002] Cable trenches have gone through several development stages: buried pipes, brick cable trenches, and reinforced concrete cast-in-place concrete trenches. In the stage of buried pipe, it is designed to wear PE or PVC double-wall corrugated pipe, which has the advantage of low cost, but the disadvantage is that it is a one-time facility with unchanged maintenance and no capacity expansion. The brick cable trench is low in cost and has scalability, but its service life is short, because the cable trench is easily damaged, and it is easy to damage the cable, causing power supply safety hazards. The cast-in-place reinforced...
