Description
Technical Field
The utility model belongs to the technical field of tunnel engineering, especially, relate to a combined type tunnel cable trench cover plate.
Background
The tunnel cable trench cover plate adopts plain concrete mostly, and its thickness is big, and weight is high, and intensity is low, the durability is poor, often sees the damaged fracture condition of cable trench cover plate corner, influences pleasing to the eye to bring certain uncomfortable to patrolling and examining personnel's the current. With the rapid development of material technology, UHPC (ultra high performance concrete) is produced at the same time, and the ultra high performance concrete takes cement as a cementing agent and is combined with various aggregates, additives and the like to form a hydraulic cementing material which has the characteristics of high strength, corrosion resistance, high impermeability, impact resistance and the like, the early development is rapid, the later strength is high, and the strength is multiple times of that of common concrete. Therefore, the UHPC is adopted as the cable trench cover plate protective layer, the section thickness can be reduced, meanwhile, the tensile, bending and abrasion resistance of the cover plate can be obviously improved, and the size and the weight of the cover plate are reduced, and meanwhile, better durability is provided.
Disclosure of Invention
In order to solve the problems, the utility model provides a simple structure, matter are light, high strength, combined type tunnel cable trench cover that the durability is good.
A composite tunnel cable trench cover plate comprises a common concrete plate and a frame type UHPC protective layer, wherein the common concrete plate is positioned in the UHPC protective layer; a clamping groove is formed in the side of the common concrete slab; the UHPC protective layer is provided with a protruding part matched with the clamping groove at the corresponding position; one side of the UHPC protective layer is also provided with an opening which is concave to the edge of a common concrete slab.
As preferred, the utility model discloses the combined type tunnel cable trench cover gross thickness that adopts is 4 ~ 8 cm.
As preferably, the utility model discloses the thickness of the UHPC protective layer that adopts is 2 ~ 3 cm.
As preferred, the utility model discloses the shape of draw-in groove that adopts can be semi-circular, square, and its diameter or length of side should be 2 ~ 5 cm.
Preferably, the distribution of the clamping grooves adopted by the utility model at each side is one or more; when the clamping grooves are multiple, the clamping grooves are distributed at equal intervals.
Preferably, the shape of the opening used in the present invention may be a semicircle or a square, and the diameter or side length is preferably 5 to 10 cm.
Compared with the prior art, combined type tunnel cable trench cover have following characteristics: the structure is simple, the weight is light, the strength is high, the durability is good, the problems of large volume, high weight, low strength and poor durability of the traditional plain concrete cover plate are solved, and the stress characteristic and the durability of the tunnel cable trench cover plate can be greatly improved.
