Construction method of canal lining with water

Abstract

The invention discloses a construction method of a canal lining with water. The method comprises the steps that firstly, a water passing groove which is formed by a water inlet end, a connecting section and a water outlet end, free of an upper cover and provided with a square section is assembled ashore, then the water passing groove is hoisted into the center of a water passing channel needing tobe lined on site, and the water inlet end and the water outlet end are both provided with horn mouths; upstream sandbags and upstream clay are arranged at the left side and the right side of the outer side of the horn mouth of the water inlet end, and upstream clay geobags are arranged at the bottom of the horn mouth at the front end of the water inlet end and used for blocking flowing water; anddownstream sandbags and downstream clay are arranged at the left side and the right side of the horn mouth of the water outlet end, downstream clay geobags are arranged at the bottom of the horn mouth of the tail end of the water outlet end and used for blocking flowing water, water in areas, defined by the upstream sandbags, the upstream clay, the downstream sandbags, the downstream clay and thewater passing groove, at the two sides of the water passing groove is pumped to form a waterless construction area, and canal lining construction is carried out. Canal lining construction can be conducted under the water passing condition, construction is rapid and convenient, investment is saved, and normal water use of people is not affected.

Description

technical field [0001] The invention relates to a construction method of canal lining, in particular to a construction method of canal lining with water. Background technique [0002] In poverty-stricken areas, some water diversion channels are often excavated without lining, and the channels leak seriously, and the water is mixed with fine particles. Long-term drinking is likely to cause harm to the human body, so it is necessary to line the channels without lining construction. However, in the lining construction, it cannot be carried out when the water is not connected or when the water is cut off like the traditional channel lining construction. Such channels in severe cold areas must ensure uninterrupted flow of water for domestic water supply and agricultural water in summer, so the lining construction must be carried out under the condition of water flow. In order to minimize the disturbance to people's life and minimize the impact on agricultural irrigation when th...
