Spraying method for construction of concrete for slope reinforcement of water-level-fluctuating zone

Abstract

The invention relates to the technical field of reservoir slope construction, and discloses a spraying method for construction of concrete for slope reinforcement of a water-level-fluctuating zone. The spraying method includes the following steps that (1) the rock face is cleaned, loose rocks, pumice stone, dust, slag and other debris on the sprayed face are removed, for a soil slope, the slope isleveled and compacted, a spraying layer mark is arranged as required, the spraying layer thickness control mark adopts rebars or metal nails, the space between the rebars or the metal nails is 3-5 m,and the length of the extension part of the rebars or the metal nails is the thickness of sprayed concrete. According to the spraying method for construction of the concrete for slope reinforcement of the water-level-fluctuating zone, the space between the arranged rebars or the metal nails is 3-5 m, the length of the extension part of the rebars or the metal nails is the thickness of the sprayedconcrete, so that the rebars or the metal nails can be covered by the sprayed concrete after spraying of the concrete is completed, the spraying quality of the concrete is increased, after installation and debugging are also completed through a spraying machine, firstly water is injected, then ventilation is conducted, and pipelines are cleaned.

Description

technical field

[0001] The invention relates to the technical field of reservoir slope construction, in particular to a spraying method for concrete construction for slope reinforcement in a water-fluctuation zone. Background technique

[0002] The reservoir ebb and flow zone, also known as the fluctuation zone or the ebb and flow area, is the area where the seasonal water level of the reservoir fluctuates and the surrounding submerged land is periodically exposed to the water surface. In addition, it also includes the ebb and flow zone caused by special climate. The formation of the belt is mainly caused by the rise and fall of water level caused by periodic flood storage or flood discharge. The sinking zone is divided into cliff bank, steep slope bank, beach slope bank and platform bank according to the slope. Before the sinking zone is formed, it grows in the reservoir area. The vegetation on both sides of the strait is a natural ecological barrier, which can intercept an...
