Embodiment Construction

[0023] see figure 1 , figure 2 , image 3 and Figure 4 . This kind of cable trench cover plate with shockproof, noise reduction and water insulation functions has two widthwise sides of the cover plate body 1, and the lower part of one side protrudes outwards to form a lapped edge 2 (see image 3 ), and the upper part of the other side is convex to form a lap edge 3 (see Figure 4 ). A supporting foot 51 is respectively arranged on the four bottom corner positions of the cover plate body 1 (see figure 2 ), each supporting foot 51 is positioned on the insert by screw screwing. An anti-noise pad 31 is fixedly provided on the lapping surface of the lapping edge 3 . The length of the bottom wall of the cover plate body 1 is fixed with buffer pads 5 on both sides, and the supporting feet 51 pass through the through holes at the corresponding positions of the buffer pads 5 . When the supporting feet 51, the anti-noise pads 31 and the buffer pads 5 are actually implemented...

Abstract

Provided is a cable duct cover plate with an earthquake prevention, noise reduction and water isolation function. A cover plate body is provided with two side faces in the width direction, the lower portion of one side face protrudes outwards to form an edge in lap joint, and the upper portion of the other side face protrudes outwards to form a lap joint edge. Adjustable bearing feet are arranged at the four bottom corners of the cover plate body respectively. After the cover plate is mounted, due to the fact that cover plates are in lap joint, good integrity is achieved, strong firmness is achieved, and the pressure bearing capacity is greatly improved. If the mounting face of a cable duct groove is out of flatness and the bottom face of the cover plate is damaged to influence flatness, the flatness of the cover plate can be adjusted conveniently by properly rotating the bearing feet and adjusting the height, and noise generated by the cover plate due to pressure bearing can be reduced or eliminated. In addition, gaskets are arranged on the lap joint edge of the cover plate and the two sides of the bottom wall of the cover plate, and the earthquake prevention and noise reduction effect is better. Besides, a groove is formed in the inner side of the edge in lap joint, rainwater on the top face of the cover plate can be prevented from entering a cable duct, and the interior of the duct is kept dry.

Description

[0001] 【Technical field】 [0002] The invention belongs to a cable trench cover plate used in power generation and transformation, municipal and railway projects, and more specifically relates to a cable trench cover plate suitable for urban communication optical cables, cable trench cover plates, sewage wells, inspection wells and other occasions. Applied cover. [0003] 【Background technique】 [0004] The cable trench is an underground special channel for laying cables. Its structure usually includes a groove with a concave cross section for receiving cables, and a cover plate covering the top of the groove. On the side wall of the groove, a load-bearing angle is welded. The steel frame shall be grounded as required. At present, concrete cover plates are commonly used to cover the cable trenches. This cover plate has the following problems in practical application: the cover plate and the cover plate are independent of each other, the connection is not tight, and the con...
