Embodiment Construction

[0037] Such as Figure 1 to Figure 5 Shown, be the construction method of a kind of desilting irrigation canal of the present invention, comprise the steps:

[0038] 1) Precast concrete

[0039] The mold is made according to the size of the main body 1 of the water channel, and the concrete reinforcement is preset in the mold. The concrete reinforcement is evenly arranged on both sides and the bottom of the main body 1 of the water channel. The number of times the mold is used is between 50-80 times. The degree of deformation determines whether to replace a new mold, and maintain the finished product after it is released from the mold;

[0040] 2) Foundation trench excavation

[0041] Use an excavator to dig out a foundation pit twice the width of the canal according to the position on the drawing. The two sides of the foundation pit are surrounded by wooden retaining walls, and a foundation trench with a depth of 10cm is excavated at the installation position of the main bo...

Abstract

The invention discloses a construction method of removing silt in an irrigation canal. The construction method comprises the following steps that 1, concrete is prefabricated; 2, a foundation groove is excavated; 3, a canal is installed; 4, silt is cleared, and 5, soil is recycled. According to the method, the problems that water quality is poor, a water body is muddy, a large amount of the silt and precipitates can be deposited at the bottom in an existing canal are solved.

Description

technical field [0001] The invention specifically relates to a construction method of an irrigation ditch for removing sediment. Background technique [0002] Canal irrigation is the basic method of crop irrigation. In the past, canal irrigation was artificially used to block or release water in the canal. Later, with the development of the times, the canal was made of concrete, and the sluice was used to realize the water canal during the irrigation process. The water in the canal is blocked, and the water in the canal will bring some silt and sediment during long-term use, which will make the water in the canal relatively turbid, and even cause adverse effects on plants during irrigation. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for removing silt and silt irrigation canals in view of the many deficiencies in the prior art, which solves the problem of poor water quality in the existing canals, turbid water...
