Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] like figure 1 As shown, the present invention provides a concrete drain pipe, which includes a tubular drain pipe body 1 , and the drain pipe body 1 includes a concrete layer 11 and a reinforcement layer 2 . The reinforcement layer 2 protrudes into the concrete layer 11 .
[0027] like figure 2 As shown, in this embodiment, the reinforcement layer 2 includes several spheres 21 distributed along the circumference of the concrete layer 11 . The sphere 21 is a mesh-shaped hollow sphere. The spheres are made of steel wire material, and two adjacent spheres 21 are connected by an arc-shaped piece 3, which includes several longitudinal steel wires 21a and several transverse steel wires 21b. The longitudinal steel wires 21a and the transverse steel wires 21b are interlaced, and steel wire knots 21c are formed at the intersections...

The invention belongs to the technical field of drainage pipes, and in particular relates to a concrete drainage pipe, aiming at solving the technical problems in the prior art that the structure strength is poor and the like. The concrete drainage pipe comprises a tubular drainage pipe body; the drainage pipe body comprises a concrete layer and a reinforcement layer; the reinforcement layer stretches into the concrete layer; the reinforcement layer comprises a plurality of sphere bodies which are distributed along the circumference of the concrete layer; every two adjacent sphere bodies are connected through an arc-shaped part; each sphere body is a net-shaped hollow sphere body; a plurality of convex ribs are arranged on the outer surface of each sphere body; every two adjacent convex ribs are mutually crossed; a hook body, which is arranged reversely, is arranged at one end, far away from the outer surface of each sphere body, of the corresponding convex rib; the hook bodies are connected with the convex ribs through detachable connecting structures; a supporting rod is arranged on the inner surface of each sphere body; the length of each supporting rod is greater than the diameter of each sphere body, and two ends of each supporting rod are connected onto the inner surface of the corresponding sphere body respectively. The concrete drainage pipe has the advantages that the design is more reasonable, the structural strength is higher, and the bearing capacity is great.
Description
technical field [0001] The invention belongs to the technical field of drainage pipes, in particular to a concrete drainage pipe. Background technique [0002] Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage. Drainage pipes are divided into plastic drainage pipes, concrete pipes and reinforced concrete pipes. Concrete pipes are widely used due to their simple structure and low cost. At present, most of the concrete pipes provided on the market are made of sand and cement. But, only its structural strength is low by the concrete pipe that sandstone, cement are poured into, and practical range is narrow. Some people also add materials such as steel to concrete pipes for reinforcement. But it still has technical problems such as reasonable design and low structural strength. In order to solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions. ...
