Description

Cable well

Technical Field

The utility model relates to the technical field of cable well construction, in particular to a cable well.

Background

The traditional electric prefabricated well adopts a common reinforced concrete or common reinforced concrete integral structure, has larger dead weight and is difficult to hoist and construct in place.

In recent years, technicians assemble the cable well by adopting UHPC (ultra-high performance concrete) precast slabs, compared with the traditional common reinforced concrete power such as the cable well, the cable well has the advantages of relatively light dead weight, relatively thin thickness, relatively convenient hoisting and in-place construction, and greatly improved strength, rigidity and durability. The spliced cable shaft is light in weight, high in strength, small in thickness, simple to process and light in installation.

The above cable well assembled from precast ultra-high performance concrete panels still suffers from the following disadvantages: 1. the cable access holes on the side plates are fixed holes, so that the requirements of different numbers and different requirements, such as the need that one or more cables in a plurality of cables need to be independently accessed and separated from other cables by a certain distance, are difficult to meet; and the defects that the support frame and the sealing are difficult to solve are needed in the well caused by the large fixed cable hole and the small diameter of the cable passing through the fixed cable hole. 2. The four side plates and the bottom plate and the four side plates and the well frame are fixed by virtue of the jogged grooves, no mutual fixing structure exists between the side plates and the side plates, certain difficulty is caused in jogged alignment during assembling, and the firmness of connection and the tightness between the plates are required to be improved. The sealing performance is that the water collecting pipe opening is arranged on the bottom plate, so that water can be collected on the bottom plate.
