The cable groove lid is actually the lid covering the cable groove; according to different materials, it is divided into ordinary cement cable grooves, composite cable grooves, and glass reinforced reinforcement cable grooves;Generally, the use of new high -end composite materials is generally widely promoted, and the development and production enhance the thermosetry composite material cable groove cover, which completely overcome the many defects of other covers.
Cable trench cover material material
The material of the cable trench cover is steel fiber concrete, composite resin, regenerative resin, polymerization complex, etc.1. Steel fiber concrete: The steel fiber is relatively bulky, construction or maintenance is inconvenient, but the cheapest price is the cheapest.2. Regenerative resin and polymerization base complex: poor temperature resistance, crispy in winter, easy to expand in summer, poor applicable effect, shorter life, and higher price than steel fiber concrete.3. Composite resin material: which is usually referred to BMC: mainly use unsaturated resin, short glass fiber, long silk, add some filling, with steel bars, with stable product performance, strong temperature resistance, acid resistance resistance, acid resistance resistanceAlkali, pressure resistance, bending, impact, flame retardant, price is relatively higher than steel fiber concrete, regenerative resin, polymerization base complexes, but high cost performance from the use of years and product performance.
Cable trench cover board specification
The selection of cable grooves cover is related to the environment and design needs used.Under normal circumstances, 38*38*30 -specified glass fiber reinforcement grille can be used as a cable trench cover.If the cable ditch cover only walks across pedestrians, 38*38*25 can meet the needs, 38*38*30 specifications are better.If you need to cross the car, it is recommended to use 38*38*38 specifications.If a large span, a forklift and even a heavy bulky car, you can use 50*50*50 or 38*38*50 specifications, or even 38*38*65 specifications.Details are subject to actual needs.
Cable trench cover plate construction process
Process process: Construction preparation -corner steel border production -corner steel frame galvanized -steel bars production and installation -concrete pouring -maintenance -cover plate installation -quality inspection (1) Material preparation: sand, stone should have there anyIn the re -examination report, the concrete should have a factories and re -examination reports; the steel bars should be checked in appearance and information (quality certificate), and the re -examination should be passed;Phenomenon, specifications, models, and wall thickness should meet the design requirements.There should be a qualified certificate for the welded stick, and the welder shall have a job certificate.(2) Preparation of prefabricated venues: The prefabricated venue shall be set in the substation area without affecting the construction site, and the size of the venue shall be determined according to the number of prefabricated and the use time.The surface of the venue should be pressed, and the surface is flat, smooth, and solid after the light (cable groove cover plate production venue (3) Technical preparation: 1) Drawing inspection: Strictly follow the "Technical Management of Power Construction Engineering Construction Technology Management" (The requirements of the following abbreviations) are checked for drawing.2) Technical intercourse: According to the guidance, each sub -item project must be graded to the construction technical intercourse.The content of the technical intercourse must be fulfilled, with targeted and instructive. Those who participate in the construction must participate in the bottom and signature to form a written record record.
