Connector device for arrangement-type pre-buried cable conduits capable of being randomly combined

Abstract

The invention discloses a connector device for arrangement-type pre-buried cable conduits capable of being randomly combined. The connector device is characterized in that the connector device is formed by combining at least one connector unit, each connector unit comprises a cable conduit connector (1), a rubber pad (2) and a cover plate (3), a rubber pad placing groove is arranged on the cable conduit connector (1), the rubber pad (2) is arranged in the rubber pad placing groove, the height of the rubber pad (2) is higher than the height of the rubber pad placing groove by 0.5 millimeter, the rubber pad (2) is arranged between the cable conduit connector (1) and the cover plate (3), the cable conduit connector (1) and the cover plate (3) are connected via bolt, and the upper edge and the lower edge of the cable conduit connector (1) are provided with a groove (1-1) and a bulge (1-2) which are matched with each other. The connector device has the advantages of safety, reliability, firmness, durability, difficulty in deformation, high applicability and long service lifetime, has effects of water and moisture resistance, and is not needed to maintain, and the resources are saved.

Description

Technical field: [0001] The invention relates to a pre-embedded cable pipe joint that can be combined and arranged at will, belongs to the technical field of electric power system cable wells and cable tunnels, is applied to the pre-embedding of cable wells and tunnels in the civil engineering part of the power system, and is connected with the cable pipe joint connection. Background technique: [0002] At present, there are two ways to connect the power cable well and the cable pipe: one is to reserve a rectangular hole of a corresponding size at the interface with the cable pipe when the formwork is supported after the cable well is bound with steel bars, and the cable pipe Insert it into the cable well, and then pour concrete; another method is to reserve a rectangular hole for the pipe to be poured first, and then penetrate into the reserved hole after the pipe is laid, and then pour concrete at the interface. These two methods have the following disadvantages: 1. Becau...

AI Technical Summary

Problems solved by technology

These two methods have the following disadvantages: 1. Because the expansion coefficient of the cable pipe is different from that of the concrete, the cable pipe interface in the cable mine is not tightly sealed, and water leakage occurs, which cannot play a waterproof role; 2. When pouring concrete, The arrangement of cable pipes is affected by the weight of the concrete and becomes irregular in the cable well, which seriously affects the laying of cables in the future; 3. The formwork inside and outside the cable well is affected by the cable pipe, and the formwork support is very troublesome and not firm; 4. Cable When the pipe is poured in combination with the cable well, the nozzle of the cable pipe will be covered with concrete. When the cable is laid, the concrete at the mouth of the cable pipe must be removed. The deep part of the pipe makes the section of the cable pipe unusable, and the concrete blocks entering the deep part are not cleaned up, and even the outer insulation of the cable is damaged and an accident occurs.

It will consume a lot of manpower and material resources to repair the cable pipes in the cable well, resulting in repeated construction, waste of resources, and inconvenience to the construction work
