Description

SMC high strength combined material railway cable shaft

Technical Field

The utility model discloses cable shaft is used for laying of railway communication, signal light (electric) cable, especially a SMC high strength combined material railway cable shaft.

Background

At present, most of cable wells designed along a railway adopt a brick-concrete structure, four walls of the cable wells are of a brick structure, a bottom plate of the cable wells is of a concrete foundation, and prefabricated components are coated on the cable wells, part of the cable wells adopt a reinforced concrete structure, the four walls of the cable wells are of precast concrete bricks, the bottom plate of the cable wells is of a reinforced concrete foundation, and reinforced concrete precast slabs are coated on the bottom plate of the cable wells. According to relevant standard, the two structures are selected according to various factors such as the corrosiveness of foundation soil and underground water, the geological firmness, the earthquake intensity and the like, and in addition, the two structures have the following problems: the cement brick built cable well has more working procedures, labor, time and comprehensive cost; certain errors can occur in cable wells with the same size, and the normalized operation is not facilitated; the cable well is deeply buried underground and is seriously influenced by the geographical environment, the phenomena of water seepage, corrosion and water shortage cracking of the cable well often occur in places with more water and stronger acidity and alkalinity or relatively dry places, the quality safety problem of the cable is seriously threatened, and the driving safety is further possibly influenced.

Disclosure of Invention

An object of the utility model is to provide a SMC high strength combined material railway cable well can prevent because of the injury that the electric leakage caused constructor, and effectual isolated rat worm ant gnaws and eats, light in weight, structural design is reasonable, and shielding effect is good, and sealing performance is good, can effectually prevent because the risk that the cable that leaks and lead to is steeped by the water.

The utility model discloses technical scheme that cable shaft adopted: the utility model provides a SMC high strength combined material railway cable well, includes the well body that comprises SMC high strength combined material, well body bottom surface is sealed, the top surface is opened and is a cable well apron of liquid seal cooperation installation, well body bottom surface is setting up a outlet of installing the sealing plug, set up cable support and cable well cat ladder on the inner wall around the well body is relative respectively, set up respectively on the inner wall about the well body is relative and advance out the cable groove, cooperate respectively on the well body outer wall in the business turn over cable groove outside and set up a encapsulating groove, the cable gets into and wears out the well body from advancing out the cable groove, the encapsulating inslot is being filled sealed gluey business turn over cable groove.

The cable well based on the SMC high-strength composite material is mainly applied to laying of communication and signal optical (electric) cables, and is convenient to construct and overhaul. The cable well is manufactured by cold die forming (a forming method of composite materials, and a product can be cured and formed without external heating), so that the size and the performance of the product can be effectively ensured, and the precision of the product is improved. The utility model discloses SMC high strength composite is chooseed for use to the cable shaft, ageing-resistant, corrosion-resistant that can be better, the life of extension cable shaft: the cable shield has the advantages of reasonable structural design, good shielding effect and good sealing performance, and can effectively avoid the risk that the cable is soaked by water due to water leakage; the environmental adaptability is strong, and the damage of environment and climate to light (electricity) can be effectively reduced; the construction process is simplified, the construction and the installation are convenient, and the maintenance cost is reduced.

Detailed Description

The utility model provides a SMC high strength composite material railway cable well, as shown in figure 1, 2, include the well body 2 that comprises SMC high strength composite material, 2 bottom surfaces of well body are sealed, the top surface is opened and is a cable well apron 3 of liquid seal cooperation installation, well body bottom surface is setting up a outlet 7 of installing the sealing plug, set up cable support 4 and cable well cat ladder 6 on the inner wall around the well body is relative respectively, set up business turn over cable groove 5 on the inner wall about the well body is relative respectively, the cooperation is setting up a encapsulating groove 1 on the well body outer wall in business turn over cable groove outside respectively, the cable is followed business turn over cable groove 5 and is got into and wear out well body 2, encapsulating groove 1 is being filled with sealed glue and is sealed business turn over cable groove 5.

In the specific implementation process, firstly, the cable well is assembled, wherein the well cover 3 is connected with the well body 2 through an M8 bolt, the top of the well body is provided with a long-life rubber plug, and the water outlet 7 is screwed and sealed through a knob. And after the assembly is finished, introducing the optical (electric) cable, and pouring glue into the glue pouring groove for the incoming and outgoing lines by using the sealant for fixing and sealing, and finally ensuring that the well cover and the well body are complete in sealing.
