Abstract

The invention relates to the technical field of side slope stability prevention and treatment research and relates to a side slope rescuing counter pressure adverse construction method and a structure thereof. The side slope rescuing counter pressure adverse construction method comprises the following steps that 1, side slope body geometric elements are determined, and side slope body physical and mechanics parameters are determined; 2, counter pressure platform parameters are determined, and counter pressure materials are determined; and 3, an adverse method is adopted for carrying out construction. The side slope rescuing counter pressure adverse construction method has the beneficial effects of being convenient in construction, fast, safe, low in cost, small in disturbance to a slope body and the like. Moreover, the method can be applied to filling embankments of highways and railways, water conservancy embankment projects, soft soil foundation pit projects and various side slope rescuing projects.

Description

technical field

[0001] The invention belongs to the technical field of prevention and control of slope stability, and relates to the rescue of slopes around roads, railways or bridges, water conservancy embankment projects and soft soil foundation pit engineering slopes, in particular to a construction method for slope rescue and reverse pressure reverse operation and its structure. Background technique

[0002] With the rapid development of social economy in recent years, more and more large-scale projects are being built, resulting in a gradual increase in the scale and frequency of disasters such as slope instability and slippage, which has become a great threat to human social security. One of the geo-environmental disasters affected. For example, slope (including foundation pit) slippage is a common engineering accident, which often causes buried damage to machinery and equipment, casualties, a large amount of property loss, and also threatens other buildings adjacent ...

Examples

Embodiment

[0076] In this embodiment, on the basis of analyzing the cause of slope failure and potential failure mode, the slope is reinforced by the reverse pressure method, and it provides a useful reference for the rescue of similar engineering accidents.

[0077] Such as figure 1 - Figure 4 As shown, the present embodiment provides a construction method for slope rescue and reverse pressure, which specifically includes the following steps:

[0078] The first step: construction preparation

[0079] Make technical and safety disclosures to the construction personnel; familiarize yourself with and check the technical performance of machinery and equipment; clean up the site, level the site, and take corresponding protective measures for those that need protection; select the source of back pressure materials and build temporary passages.

[0080] Step 2: Determine the 100 geometric elements of the slope body

[0081] Measure 100 geometric elements of the side slope body in the area...
