A kind of anti-subsidence subgrade construction method

Abstract

The invention provides a construction method of an anti-settlement subgrade. Real-time automatic subgrade settlement compensation also can be used while settlement artificial compensation is realized;meanwhile, lateral displacement of the subgrade also can be prevented without the need of arranging an earth retaining wall.

Description

technical field [0001] The invention relates to a roadbed construction method, in particular to an anti-subsidence roadbed construction method. Background technique [0002] With the vigorous development of our country's economy and the continuous progress of society, the role of highway bridges on people is becoming more and more important, and its construction technology is also constantly improving. In recent years, all parts of the country have attached great importance to the construction of roads and bridges. Highway bridges not only become the main arteries connecting the north and south economies, but also promote economic development to a certain extent. Highway bridges belong to the national infrastructure construction, and the requirements for construction technology are very high. However, the current technical level in our country is not mature enough, and many technologies are not perfect enough. Therefore, relevant departments attach great importance to the c...

Problems solved by technology

However, this method also has the following defects. On the one hand, it needs to be manually carried out after the subgrade settlement has occurred to a certain extent, and it is not real-time compensation; The water absorption is relatively large, and the quicklime bag produces lateral displacement when absorbing water. In order to prevent the lateral deformation of the roadbed, retaining walls need to be installed on both sides of the roadbed
