The utility model discloses the purpose is exactly for solving prior art not enough, has proposed a novel cable trench cover, has waterproof and ventilation function concurrently, the installation is light, lay simple, easily production.

In some embodiments, the following technical scheme is adopted:

a novel cable trench cover, comprising: the two ends of each cover plate unit are respectively provided with a first clamping groove and a second clamping groove which are opposite in direction; two adjacent apron units can realize the joint through two opposite direction's draw-in grooves, and all apron units link together through the mode of joint.

As a further scheme, the opening direction of the first card slot faces upwards, and the opening direction of the second card slot faces downwards.

As a further scheme, a first waterproof strip is arranged at the end part of the first clamping groove.

As a further scheme, the first waterproof strip is a silica gel waterproof strip.

As a further scheme, the cover plate unit is provided with a vent hole for communicating the cable trench with the outside.

As a further scheme, a PVC pipe is arranged in the cover plate unit and is communicated with the cable trench and the outside.

As a further scheme, the opening direction of the PVC pipe faces the drainage direction of the field.

As a further alternative, the number of PVC pipes may be determined according to the width of the cover plate or the actual requirements.

As a further scheme, the cover plate unit is made of ceramsite lightweight aggregate concrete materials.

As a further scheme, a second waterproof strip is arranged at the position where the cover plate unit is contacted with the cable trench wall.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the utility model discloses cable trench cover has adopted haydite lightweight aggregate concrete material, can alleviate cable trench cover's dead weight.

(2) The utility model discloses the apron unit sets up first draw-in groove, as the rainwater guiding gutter simultaneously, can be with rainwater water conservancy diversion to cable pit outside within range.

(3) The utility model discloses two adjacent apron unit overlap joints are accomplished the back, will be sealed completely along the draw-in groove direction, have reached better water-proof effects.

(4) The utility model discloses at cable trench cover one side inside lining PVC pipe, can solve the ventilation problem in the cable trench.

Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

In the case of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

Example one

In one or more embodiments, a novel cable trench cover is disclosed, with reference to fig. 1, comprising: the cover plate unit comprises a plurality of cover plate units 6, wherein a first clamping groove 1 and a second clamping groove 2 which are opposite in direction are respectively arranged at two ends of each cover plate unit 6; two adjacent apron units 6 can realize the joint through two opposite direction's draw-in grooves, and all apron units 6 link together through the mode of joint, form cable trench cover.

Specifically, the opening direction of the first card slot 1 is upward, the opening direction of the second card slot 2 is downward, and the first card slot 1 and the second card slot 2 can be matched and clamped. The cover plate units 6 are sequentially laid on site and are clamped in front and back through the clamping grooves in an overlapping mode.

Because the opening of the first clamping groove 1 is upward, the first clamping groove can also be used as a rainwater diversion groove to divert rainwater to the outer side of the cable trench.

In addition, for guaranteeing water-proof effects, first waterproof strip 3 is placed to 1 tip position of first draw-in groove, and the overlap joint is accomplished and is sealed the draw-in groove completely along the draw-in groove direction to reach better water-proof effects. Optionally, the waterproof strip is a silica gel waterproof strip.

As an alternative embodiment, the cover plate unit 6 adopts a ceramsite lightweight aggregate concrete material to reduce the dead weight of the cable trench cover. Compared with the common concrete material, the ceramsite lightweight aggregate concrete material has equivalent strength and durability, but the weight is only 60-75% of that of the common concrete material.

As an alternative embodiment, referring to fig. 2 and 3, in order to solve the problem of ventilation in the cable trench, a vent hole for communicating the cable trench with the outside is provided in the cable trench cover plate; in some embodiments, a PVC pipe 4 is lined on one side of the cable trench cover plate, the PVC pipe 4 connects the cable trench with the outside, and the number of the PVC pipe 4 can be increased or decreased according to the width of the cover plate. When the cable trench cover plate is paved, one side of the PVC pipe 4 is required to face the drainage direction of the field.

As an alternative embodiment, referring to fig. 3, in order to ensure the waterproof effect, before laying the cable trench cover, a second waterproof strip 7 is laid along the cable trench wall 5, and optionally, a silica gel waterproof strip is used as the waterproof strip.

Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
