Abstract

The invention provides a roadbed building lap joint structure and a construction method and relates to the technical field of roadbed building construction in road engineering. The structure comprisesan existing concrete structure and a stepped foundation pit, wherein the stepped base pit is arranged downwards from the original ground, and one side of the stepped foundation pit is contacted withthe existing concrete structure; the stepped foundation pit comprises multiple step planes and step slopes which are arranged downwards from the original ground; a filling layer is arranged in the stepped foundation pit, the filling layer fills the stepped foundation pit to be flush with the original ground in the horizontal direction, and the filling layer is contacted with the existing concretestructure in the vertical direction. The technical problem of non-uniform settlement of a roadbed lap joint area in the prior art is solved.

Description

technical field [0001] The invention relates to the field of roadbed filling construction in road engineering, in particular to a roadbed building lap joint structure and a construction method. Background technique [0002] In recent years, with the rapid development of my country's economy and urban roads, the quality of urban roads, especially roadbed filling, has become higher and higher. If the quality of roadbed filling is poor, many hidden dangers will be left on the road surface and the roadbed itself, resulting in poor quality of the road surface. The use quality and service life of the road will be reduced, and the serious damage to the roadbed or road surface will even interrupt the traffic and cause major economic losses. When the subgrade filling is overlapped with the existing concrete structure, how to avoid uneven settlement in the subgrade overlapping area is the key point of construction. If the control is not good, it is easy to cause uneven settlement in th...
