The purpose of this utility model can realize by following technical scheme:

A kind of combined cable trench, comprise a plurality of cable beareves, it is characterized in that: also comprise the connected head-to-tail cell body of more piece, described cell body cross section takes the shape of the letter U, described cable bearer is arranged above and below and is located on the sidewall of described cell body, and two row cable bearer height of the two side of described cell body are corresponding.

On the basis of the above, the utility model can also be done further improvement:

The inside of described cell body is provided with reinforced mesh, reinforced mesh and cell body shape, big or small corresponding.

The both ends of the surface of described cell body are chamfering by groove inwall place, after being convenient to connect end to end mutually between the cell body, with cement mortar abutment joint are carried out shutoff.

Two row cable beareves on the two side of described cell body front and back dislocation are mutually arranged.

Be provided with the cable bearer reserving hole corresponding to the cable bearer placement on the two side of described cell body, described cable bearer is bumped into described cable bearer reserving hole.

Described cell body two side is provided with the wall thickness thickening at cable bearer reserving hole place extremely more than or equal to 100mm.

On the end face of described cell body two side, the place is provided with groove corresponding to the cable bearer reserving hole, and bottom portion of groove is provided with hoisting ring, and the hoisting ring end face is lower than described cell body sidewall end face.

After described cable bearer is bumped into reserving hole, make the support afterbody leave the space, carry out the afterbody shutoff with the cement mortar plugged zone apart from cell body sidewall outer surface.

Back gauge groove end, the most Last hole of described cable bearer reserving hole is more than or equal to 200mm; It is 100mm, trapezoidal for 60mm highly that the top cross section of the two side of described cell body is thickness.

Beneficial effect: compared with prior art, the utility model adopts prefabricated formal product production to the cable cell body, carries out assembly unit with cable bearer at the scene then, behind the cable trough rigging out, suspension ring hole, cell body and slit, cell body connection place all adopt cement mortar to seal obstruction, cancelled the scene and built by laying bricks or stones, operating environment has not almost been had influence, the manual work of being more convenient for, after cable trough and the disposable assembly unit of cable bearer again lifting connect, assembly unit speed is fast, the efficient height, and operating expenses is low.And the bulk strength height, good endurance.

Embodiment

Combined cable trench is one of embodiment of the present utility model as shown in Figure 1 to Figure 3, comprise a plurality of cable beareves 2 and comprise the connected head-to-tail cell body 1 of more piece, the cell body cross section takes the shape of the letter U, cable bearer is arranged above and below and is located on the sidewall of described cell body, and two row cable bearer height of the two side of cell body are corresponding.

Referring to Fig. 4 to Fig. 6, the unit length of cell body 1 is 1000mm, and the heavy wall benchmark of two side is 50mm, and the upper design in cell body 1 two side becomes thickness to be 100mm, highly to be the trapezoidal cross-section of 60mm.

Be provided with cable bearer reserving hole 3 corresponding to the cable bearer placement on the two side of cell body, cable bearer is bumped in the cable bearer reserving hole, the quantity of reserving hole 3 is adjusted according to the number of plies of cable bearer, and the mutual front and back dislocation of two row cable beareves on the two side of cell body is arranged.

In the present embodiment, every sidewall is provided with 4 support reserving holes in the single cell body, and 4 support reserving hole height on the two side are corresponding, the front and back mutual dislocation arranges that the closest approach of back gauge groove end, the most Last hole of cable bearer reserving hole is 200mm.

In addition, the cell body two side is provided with the wall thickness at cable bearer reserving hole place and thickeies to 160mm, makes cable bearer 2 have enough spaces to be bumped into, and simultaneously cell body is played booster action.

In order to reinforce cell body, cell body 1 inside also can be equipped with reinforced mesh, and reinforced mesh is corresponding with cell body 1 size, as shown in Figure 7.

Be illustrated in figure 1 as support and combined cable trench assembling schematic diagram, 8 supports 2 are bumped into respectively in 8 support reserving holes 2, guarantee that simultaneously support 3 afterbodys have the 10mm distance apart from the cell body surface, carry out the afterbody shutoff with the mortar plugged zone, as shown in Figure 9.

Carry out shutoff for the ease of being coupled to each other the back abutment joint between the cell body 1, also each designs the chamfering 6 that a 20 * 20mm is arranged by groove inwall place in the cell body both ends of the surface, as Fig. 3 or shown in Figure 6.

Simultaneously, for the ease of the lifting of combined cable trench, also be provided with hoisting ring 5, as shown in Figure 10 and Figure 11 in cable cell body both sides.On the end face of cell body 1 two side, the place is provided with groove corresponding to the cable bearer reserving hole, and bottom portion of groove is provided with hoisting ring, and the hoisting ring end face is lower than cell body sidewall end face 5-10mm.

After cable trough had lifted, the slit of suspension ring hole, cell body and cell body connection place all adopted cement mortar to seal obstruction.

Concrete work progress of the present utility model is: after cable trough digs, at first cable bearer is embedded cell body, and with cement mortar plug rack afterbody, the cable trough external member that will assemble cable bearer by hoisting ring hangs in the cable trough afterwards, with cement mortar support preformed hole and the combination groove interface section at hoisting ring place carried out shutoff, in case underground water infiltrates thereafter.

In addition, the width of combined cable trench, highly, wall thickness, the cable trough number of plies of setting up, all can be according to project situation, top bearing load size cases adjusts accordingly, the foregoing description only is used for helping to understand the utility model, and is not used in restriction the utility model.

Adopting this kind combination cable groove because of not using clay brick, only use the part cement mortar to be used for the slit shutoff on a small quantity, thereby environment is influenced hardly, is a kind of environment-friendly cable groove.The combination cable groove that the utility model proposes adopts the prefabricated production of batch production, at the scene special stand is bumped into the method for row lifting more then, has cancelled the scene and has built by laying bricks or stones, quick for installation rapid, speed of application improves more than three times, can reduce operating expenses 50%, and cable trough intensity height, not cracky.
