Mortar plastering anti-cracking structure for irrigation canal

Abstract

The invention discloses a mortar plastering anti-cracking structure for an irrigation canal. The mortar plastering anti-cracking structure comprises an anti-leakage base layer for a slope surface of the irrigation canal and a mortar plastering layer on the anti-leakage base layer, and is characterized in that a netted grating structure is arranged in the mortar plastering layer on the anti-leakage base layer, a plurality of vertically through stepped holes are formed in the netted grating structure, and cement nails are arranged in the stepped holes and are nailed on the anti-leakage base layer under the cement nails. The mortar plastering anti-cracking structure has the advantages that PVC (polyvinyl chloride) dividing strips are spliced to form the netted grating structure, the netted grating structure is arranged in the mortar plastering layer, the vertically through stepped holes are formed in the netted grating structure, and the cement nails penetrate the stepped holes, so that the netted grating structure can be integrally connected with the anti-leakage base layer, and the mortar plastering layer is filled among a plurality of meshes which are formed by the netted grating structure in an enclosed manner and have the minimum sizes.

Description

technical field [0001] The invention relates to an anti-cracking structure for the mortar plastering surface of an irrigation canal, in particular to an anti-cracking structure for the mortar plastering surface of an irrigation canal which is not easy to crack, has good use effect and relatively low production cost. Background technique [0002] Field drainage and irrigation channels have small cross-sections, large quantities, and high anti-seepage requirements. Before technical improvement, the methods used were: the anti-seepage masonry is mostly mortar masonry, concrete and brick masonry, and anti-seepage block masonry After forming, it is necessary to use cement mortar to plaster the surface to prevent seepage and reduce the roughness of the water section of the channel. However, in this way, the processing strength of the anti-seepage masonry is relatively high, which is time-consuming. For this reason, the technology is improved. The anti-seepage base layer pressed by...

Problems solved by technology

However, in this way, the processing strength of the anti-seepage masonry is relatively high, which is time-consuming. For this reason, the technology is improved. The anti-seepage base layer pressed by non-burning concrete is now used, which has the characteristics of convenient masonry and good shape. However, after the plastering treatment, regular cracks appeared on the plastering surface of the drainage and irrigation canals

Designing an expansion joint with a length of 15 to 20 meters established in the code is far from meeting the actual use requirements. It is proved by practical observation that temperature-changing cracks appear about every 2 to 3 meters, and the cracks cannot meet the use requirements. Water leakage and water seepage will also cause damage to the durability of the masonry. However, the traditional method of increasing the number of expansion joints has the problems of high cost and inconvenient construction.
