Shirt rim type cylinder mould sand barrier and sand blocking and fixing construction method thereof

Abstract

The invention aims at providing a shirt rim type cylinder mould sand barrier capable of blocking and fixing a shifting desert and a sand blocking and fixing construction method thereof, belonging to the technical field of engineering. The shirt-rim type cylinder mould sand barrier comprises a cylinder mould support frame, a fixing holding strip, a cylinder mould surface and a cylinder mould shirt rim. The sand blocking and fixing construction method of the shirt rim type cylinder mould sand barrier comprises the following steps of: stacking sand of a desert into a sand pit with height more than 15 cm; spanning the shirt rim type cylinder mould sand barrier over the top of the sand pit; embedding shirt rims positioned at both sides of a cylinder mould into the sand pit; and lifting the shirt rim type cylinder mould sand barrier from the sand when only the top edge of the cylinder mould is not buried by the shifting sand of the desert to only remain, wherein the shirt rims of the cylinder mould are completely embedded into the sand pit when the lifting is finished.

Description

technical field [0001] The invention relates to the technical field of sand control engineering, in particular to a skirt-type mesh cage sand barrier and a sand retaining and sand fixing construction method thereof. Background technique [0002] In the field of sand prevention and sand fixation technology, people use a variety of sand-blocking nets, but no matter what type of sand-blocking nets, a common feature is that the sand-blocking net must be supported and fixed by a support rod inserted into the desert. It seems solid, but it is very easy to be washed away by the wind to wash away the sand under the bottom of the sand-blocking net, causing the sand-blocking net to be overhead, quicksand flowing away from the bottom of the sand-blocking net, and the sand-blocking net is very easy to be blown down by the wind. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects of t...
