Pile array sand fixing method

Abstract

A pile array sand fixing method relates to an engineering sand control method. Piles are inserted in sand directly to form a pile array. The piles are vertically fixed through the underground portions of the piles, and overground portions of the piles disturb wind-drift sand. The ratio of total surface area of the overground portions of the pile array to floor area is larger than 25%, and drift sand is basically fixed. When the ratio of total surface area of the overground portions of the pile array to floor area is little, semi-fixed effect of different degrees can be achieved. When sand accumulated in the pile array reaches a certain thickness, the height of pile bodies is uplifted correspondingly, and new sand fixing performance can be recovered. The pile array sand fixing method overcomes the shortcoming that an existing glass check sand fixing method wastes labor and time, is low in work efficiency, high in cost, short in service life and the like, and has the advantages of being simple and reasonable in structure, low in cost, strong in practicability, convenient to pave and bury, long in service life and the like.

Description

technical field [0001] The invention relates to an engineering sand control method, in particular to a pile array sand fixation method. Background technique [0002] At present, the grass grid sand fixing method is mostly used in engineering sand fixing methods, so there are defects such as time-consuming, low work efficiency, high cost, and short service life; it is very difficult to lay grass grids in the windy season, and the loss of raw materials is great. . Clay square sand barriers are not widely used due to the limitation of raw material sources. The raw material transportation cost of the tree branch grid sand barrier is very high, and the sand will lose its effect if it cannot be lifted up after the sand is buried. High vertical sand barriers are also difficult to achieve elevation and reuse. Moreover, the general engineering sand fixation technology cannot achieve the "semi-fixed" effect, the sand accumulation area is small, the sand holding capacity is insuffic...

AI Technical Summary

Problems solved by technology

The raw material transportation cost of the tree branch grid sand barrier is very high, and the effect will be lost if the sand cannot be lifted up after the sand is buried

High vertical sand barriers are also difficult to achieve elevation and reuse

Moreover, the general engineering sand fixation technology cannot achieve the "semi-fixed" effect, the sand accumulation range is small, the sand holding capacity is insufficient, and the sand fixation performance will fail because the sand barrier is buried by sand.
