Embodiment Construction

[0038] Such as figure 1 Shown, adopt following technical scheme for the construction method of a kind of stone material surface spraying protection concrete of the present invention, comprise the steps:

[0039] 1) Surface treatment to be sprayed:

[0040] a. First, clean up the slope surface, remove the loose pumice and slag on the slope surface, remove the obstacles on the slope surface, and then fill the cavity with stones, and then use 1.0m 3 The backhoe excavator will flatten and compact the surface of the rock to be sprayed to improve the compactness of the slope to be sprayed and facilitate the processing and construction of the slope in the later stage;

[0041] b. Then the designer draws the design drawing according to the local climate, environment and actual terrain, and conducts the raw material test indoors to determine the proportion of cement, gravel, medium sand, alkali-free quick-setting agent and admixture, so that Improve the strength of concrete, make the...

Abstract

The invention discloses a construction method of concrete spraying and curing on the stone surface. The construction method comprises the following steps of (1) to-be-sprayed surface treatment, (2), thickness-spraying sign embedding, (3), drainage hole embedding, (4), mixture stirring, (5), spraying and (6) curing. According to the construction method of concrete spraying and curing on the stone surface, the structure is simple, and the practicability is high; the concrete slump degree of the slope surface is small after construction through the construction method, the protective effect is good, and the strength for resisting sea wave erosion is increased; the service life of the slope surface is prolonged, the construction time can be saved through the construction method, and the construction step is simplified; and meanwhile the difficulty that the large stone resources are deficient in the prior art can be solved.

Description

technical field [0001] The invention relates to a construction method for spraying and protecting concrete on the surface of stone materials. 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 excavation and high filling are very common. Slope engineering The problem is becom...
