Embodiment Construction

[0030] like Figure 1 to Figure 5 Shown, be a kind of slope shoulder stone gap spraying concrete construction method of the present invention, comprise the steps:

[0031] (a) Slope shoulder stone area division: between the area divisions, the slope surface can be cleaned, the loose pumice and rock slag on the slope surface should be removed, the obstacles on the slope surface should be removed, and then stone blocks can be used to repair Then use a backhoe excavator to level and compact the surface of the stone to be sprayed to improve the compactness of the slope to be sprayed and facilitate the later treatment and construction of the slope.

[0032] Divide the entire slope shoulder into a first stone area and a second stone area, the divided first stone area is close to the river bank, and the divided second stone area is far away from the river bank. In the process of dividing the shoulder stone area, a protective fence is built at the outer 5m of the first stone area and...

Abstract

The invention discloses a construction method for jet-grouting concrete among stone gaps of a slope shoulder. The construction method comprises the following steps: (a) dividing stone regions of the slope shoulder; (b) laying plastic base plates in a second stone region; (c) cleaning a drainage tank; (d) placing stones in the second stone region; (e) jet-grouting concrete among stone gaps in the second stone region; (f) placing stones in a first stone region; (g) jet-grouting concrete among stone gaps in the first stone region; and (h) curing the second stone region and the first stone region. The construction method is used for jet-grouting concrete for the two stone regions of the slope shoulder, the concrete is jet-grouted into a rubble layer of the second stone region, and clear water can be injected into the drainage tank in the process to improve the effect on reinforcing the rubble layer, and the concrete is jet-grouted into a stone layer of the first stone region to improve the effect on reinforcing the stone layer, so that the second stone region and the first stone region form a mixed body with a certain strength and thickness, and furthermore, the slope shoulder has a protective effect and can resist to the erosion of waves during tide rising.

Description

technical field [0001] The invention belongs to the technical field of slope shoulder reinforcement, and in particular relates to a construction method for spraying concrete in gaps between stone materials on slope shoulders. Background technique [0002] In the practice of civil engineering production, with the construction and development of projects such as railways, highways, reservoir areas or sites, a large number of technical issues of slope engineering have been involved. The knowledge and achievements of soil engineering and soil mechanics have accumulated rich experience in slope engineering, and have made great progress and development in both theory and practice. [0003] In recent years, with the extension and development of expressway construction to mountainous areas, due to its high technical level, difficult terrain conditions, complex geological structures, and fragile geological environment backgrounds in mountainous and coastal areas of our country, deep ...
