Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to accompanying drawings 1 and 2, an assembled trench for construction site, including trench main body 1, protective plate 4 and plug 5; The groove is formed and embedded in the reserved position on the road; the top and bottom of the groove main body 1 are provided with wings 11 to form a C-shaped structure, and the wings 11 at the top of the groove body 1 and the protective plate 4 are spaced with Several pin holes 6 enable the protective plate 4 to be locked on the pair of groove main bodies 1 through the pin 5 through the pin holes 6, and the protective plate 4 can completely cover the groove.

A plurality of supports 3 are connected between the pair of groove bodies 1 at intervals, and the plurality of supports 3 are located in the grooves below the protective plate 4. Preferably, the supports 3 and the groove bodies 1 are fixed by welding. It plays the role of supporting a pair of groove main bodies 1, and can also be used as a temporary water pipe and cable in the groove bracket, and can also be used as a sling fixing point for the hoisting of the assembled groove, which is convenient for assembly.

The cross-section of the support member 3 is a ⊥-shaped structure, and the top of the support member 3 abuts on the lower surface of the protective plate 4, which can support the protective plate 4 and prevent the protective plate from driving on the road or when there are heavy equipment. 4. The utility model can be matched with grooves of different widths by adjusting the size of the support 3 even if it is deformed or even broken under pressure.

At least three support members 3 are arranged between the pair of groove main bodies 1 to ensure the strength of the assembled groove.

One end of the wing plate 11 on the top of the groove body 1 is provided with a connector 2, and one end of the connector 2 is provided with a pin hole 6 and extends to the outside of the groove body 1, so that the two groove bodies 1 can pass through the plug. 5 is spliced through the pin hole 6 on the connector 2 and the pin hole 6 on the wing plate 11 to meet the assembly requirements of grooves of different lengths. Preferably, the connecting piece 2 can be directly welded on the wing plate 11 on the top of the groove main body 1 to facilitate assembly.

The protective plate 4 is provided with a reserved hole 41 to facilitate the installation of temporary water pipes and cables inside the groove, and also facilitate the disassembly and assembly of the plug 5 .

The width of the protective plate 4 is larger than the width of the groove, so that the cover of the protective plate 4 can extend and cover the road surface when installed on the two groove main bodies 1, which can strengthen the protection of the road surface on both sides of the groove. effect.
