Embodiment

[0040] The control method applicable to subgrade slope landslides includes the following steps:

[0041] S1. Step-type unloading: carry out step-type unloading on the high and steep subgrade slope body 1 that has slumped and deformed, and unload the high and steep subgrade slope body 1 into a stepped unloading platform, so that the deformed high and steep subgrade slope body tends to be stable , to provide prerequisites for the subsequent grouting of the steel flower tube 5 and the construction of the new reinforced anti-slide pile 4 to ensure construction safety.

[0042] S2. Grouting of steel flower tube 5: as attached figure 1 And attached figure 2 As shown, the unloading platform (i.e. attached figure 1 On the unloading platform on the far right side of the middle), several rows of steel flower pipes 5 are arranged, the transverse spacing of the steel flower pipes 5 is 3-6m, preferably 4m, and the row spacing is 1-3m, preferably 2m; the steel flower pipes 5 are embedded...

Abstract

The present invention relates to the field of side slope or slope stabilization treatment, and discloses a treatment method suitable for roadbed slope body collapse. The method comprises the followingsteps of: S1, stepped downloading; S2, grouting of steel flower tubes; S3, addition of a reinforced slide-resistant pile; S4, surface and underground intercepting drainage; and S5, slope treatment. The treatment method suitable for roadbed slope body collapse is suitable for reinforcing treatment in a later remediation mode for the roadbed slope body which generates slippage deformation and an inclined slide-resistant pile so as to effectively avoid further deformation treatment of the high and steep road roadbed slope body, is obvious in treatment effect, does not need extra land acquisition, is less in occupation of land, reduces land acquisition cost and related removal expense and is low in treatment cost.

Description

technical field [0001] The invention belongs to the field of stability management of side slopes or slopes, and in particular relates to a management method suitable for landslides of subgrade slopes. Background technique [0002] With the rapid development of our country's economy, large-scale construction of railways, highways and water conservancy projects in mountainous areas has formed a large number of artificial slopes. Slope is an important part of highway engineering, and the overall effect of slope protection directly affects the overall stability of highway subgrade. [0003] Some roads inevitably need to pass through steep terrain such as mountains and valleys during construction. At this time, roadbeds need to be built on high and steep slopes. Due to its large slope and high inclination, the high and steep subgrade slope itself is prone to landslides. In addition, it has been soaked by rainwater for many years, and the shear strength of the soil is significant...
