Abstract

The invention relates to a water-permeable water discharge pipe, wherein the surface of the water-permeable water discharge pipe is a non-porous structure, and has a porosity of 40-60%, the water-permeable water discharge pipe is prepared from ceramic sand, a plasticizer and a binder, the binder accounts for 10-30 wt% of the ceramic sand, and the plasticizer accounts for 0.1-3 wt% of the ceramic sand. The preparation method of the water-permeable water discharge pipe comprises: uniformly mixing ceramic sand, a plasticizer and a binder according to a certain ration, pouring the mixture into anextruder, carrying out one-time extrusion molding, and curing for 3-4 days at a room temperature after molding. According to the present invention, by using the ceramic sand having a pore structure asthe raw material, the water-permeable water discharge pipe has a certain water absorption performance and water permeable effect, drilling is not required during the use, and the average water permeable rate can reach 6 m / s; and by matching the plasticizer and the binder, the strength of the water-permeable water discharge pipe is ensured, the breaking load is above 18KN / m<2>, and the water-permeable water discharge pipe can meet the strength requirements in the conventional application environment, and has wide application range.

Description

technical field [0001] The invention relates to the field of urban construction, in particular to a permeable drainage pipe. Background technique [0002] Drainage pipes are widely used in water supply and drainage systems such as roads, railway subgrades, subway projects, tunnels, green belts, sports fields, etc., as well as underground light improvement and drainage systems for agriculture and horticulture. Drainage pipes are mainly divided into plastic drainage pipes, concrete pipes, reinforced concrete pipes and stainless steel drainage pipes. Among them, the cost of stainless steel drainage pipe is relatively high; the cost of plastic drainage pipe is low, the performance is stable but it is easy to be damaged. At present, underground plastic drainage pipes are more common, but the outer wall is exposed to the soil environment for a long time, which is easy to cause bacteria to grow, and the inner wall often has dirt deposition, which will cause bacteria to grow in the...
