Parabola-shaped lap joint assembly type channel

Abstract

The invention relates to a parabola-shaped lap joint assembly type channel. The parabola-shaped lap joint assembly type channel structurally comprises a trench, and multiple trenches can be quickly connected through lap joint to form canals of different lengths; one side of the trench extends outwards to form a step-shaped connector; the other side of the trench horizontally extends to form a lap; the lap can be horizontally lapped on the connector; and a water stop strip (or water strop rod) is placed between the lap and the connector, and the purposes of water sealing and seepage prevention are achieved through gravity extrusion of the trench. According to the parabola-shaped lap joint assembly type channel, through the lap joint manner, the water sealing effect is good, construction is simple and convenient, less manpower is required, industrialized prefabrication and mechanical construction can be achieved, and product quality is easily guaranteed.

Description

technical field [0001] The invention relates to a parabola-shaped lap joint assembled channel. Background technique [0002] my country is a country seriously short of water resources, with a total water resource of about 2.8 trillion m 3 , the per capita water resource occupancy is 2200m 3 , is only 1 / 3 of the world's per capita share, and the share of water resources per unit area of ​​cultivated land is only 1 / 2 of the world's average level. At the same time, my country's water resources are unevenly distributed in time and space, water and land resources do not match, water use efficiency is not high, water waste and water pollution are serious, which exacerbates the shortage of water resources. Therefore, it is of great significance to actively promote water-saving irrigation technology and develop water-saving agriculture to alleviate the contradiction between the supply and demand of water resources in my country and the sustainable and stable development of agricul...

Problems solved by technology

However, in the current application of prefabricated channels, there are: ① confused with traditional prefabricated masonry channels, thinking that lengthened prefabricated channels are prefabricated channels; Waterstop, the service life of the waterstop strip is short, and the waterstop effect is poor; ③The section is mostly rectangular or U-shaped, with inflection points in the section, the mold is complicated to make, and the prefabricated components have poor stress and frost heave resistance; ④High requirements for the canal foundation , to adapt to defects such as poor deformation capacity of the canal foundation
