Problems solved by technology

Because the slope platform is narrow and the width is often between 1m and 2m, it is difficult to use mechanical operations. Therefore, the new measures also have the problems of long construction period caused by manual operations and concrete maintenance, high structure itself and high construction costs.

Embodiment Construction

[0016] The structure of a new type of slope platform drainage ditch proposed by the present invention is composed of a modified soil body, plus a glass fiber geogrid layer outside the modified soil and a plastering mortar layer on the surface of the platform side ditch; The solid weight mixing ratio of the modified soil is 10% cement and 90% excavated granite residual soil material, and then the prepared modified soil material is added with an appropriate amount of water, and mixed on site with an excavator until it is soft and plastic. , the structural molding is realized by wrapping the geogrid; the construction method of the novel slope platform drainage ditch has the following steps:

[0017] ① After the excavation work of the slope construction section is completed, excavation is firstly used to excavate and fill from the edge of the platform, and through the platform with a width of 1m, the granite with a horizontal distance of 75cm at the foot of the slope on the upper l...

Abstract

The invention discloses a construction method of a novel side slope platform drainage ditch. The step-by-step segmented excavation and backfill manner and site stirring and rapid forming constructionmethod is adopted, and compared with the similar methods, the method has the advantages of being high in construction speed, capable of easily controlling the construction quality, low in engineeringcost and the like and is particularly suitable for platform side slope construction of thick-layer granite residual soil and sandy soil high slopes.

Description

technical field [0001] The invention relates to a construction method of a slope platform drainage ditch, in particular to a construction method of a modified soil platform side ditch. Background technique [0002] The cutting slope in the thick-layered granite residual soil distribution area is mainly sandy soil with low cohesion and is easily eroded by rainwater. The side ditch of the platform is often eroded and damaged due to water leakage and splashing, or the eroded soil of the upper level slope collapses at the toe of the slope to cause blockage, resulting in damage and failure of the side ditch, which in turn induces large-scale scouring damage on the slope. [0003] At present, the platform side ditch is mainly made of mortar rubble structure, which can only be constructed manually due to the narrow construction site, so there are defects such as long construction period, poor economic benefits, and difficult quality control. Due to the lack of flake materials and ...
