Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0030] see first figure 1 , figure 2 , image 3 and Figure 4 , figure 1 , figure 2 , image 3 and Figure 4 A preferred embodiment of the present invention is shown. As can be seen from the figure, the roadbed anti-settling device of the present invention is composed of multiple hollow tubes 61, two restraint baffles 62 and multiple pre-tightening bolts 63. The two The block constraint baffles 62 are provided with a plurality of uniformly arranged circular through holes 621 corresponding to each other for installing the pre-tightening bolts 63, and the hollow circular tubes 61 are sleeved on the pre-tightening bolts 63 Above, insert the two ends of the pre-tightening bolt 63 into the corresponding circular through hole 621 of the constraint baffle 62 and fasten th...

Abstract

The invention provides a subgrade anti-settlement device and an installation method thereof. The device consists of a plurality of hollow round pipes, two constraining baffles and a plurality of pre-tensioning bolts; the two constraining baffles are correspondingly provided with a plurality of round through holes which are uniformly distributed and used for mounting the pre-tensioning bolts; the hollow round pipes are sleeved on the pre-tensioning bolts; and the two ends of the pre-tensioning bolts are inserted in the corresponding round through holes of the constraining baffle and the hollow round pipes are fastened between the two constraining baffles by nuts. The subgrade anti-settlement device has the advantages of simple structure, low cost, good anti-settlement performance, and can effectively prevents secondary jumping, and the like.

Description

technical field [0001] The invention relates to a roadbed anti-settling device, in particular to a roadbed anti-settling device and an installation method thereof which can effectively reduce roadbed subsidence caused by lateral slippage, has good roadbed anti-settling performance, simple structure, and low cost. It can be widely used in the plank type solution to prevent the phenomenon of vehicle jumping at the bridge head. technical background [0002] With the rapid development of social economy, expressways have been greatly developed in China, and gradually formed a criss-cross expressway network radiating across the country. Judging from the high-grade highways that have been put into use, especially expressways, there are many problems. Among them, the more common road disease is "jumping at the bridgehead" caused by the settlement difference between the bridgehead and the roadbed. Vehicle jumping at the bridge head has become a problem that should be paid attention ...
