Embodiment Construction

[0030] like figure 1 Shown: An embedded concealed soil nailing construction method combined with the basement exterior wall structure, which includes the following steps:

[0031] Step 1: Earthwork slope

[0032] The earthwork on the sideline of the basement exterior wall is sloped and trimmed according to the slope of 60°;

[0033] Step 2: Construction of soil nailing slope grooves

[0034] After the slope is corrected, lay out the lines according to the spacing requirements of the soil nail design, and open the groove 2 of the horizontal and vertical soil nail anchor heads. The soil nails are enlarged head soil nails, put the soil nail anchor heads into the grooves and Bind the steel bars and anchor them through the transverse ribs 11, the vertical ribs 12 and the corbel ribs 13;

[0035] Step 3: Spray the first layer of reinforcement protection

[0036] After all the slope grooves are corrected, in order to avoid contact between the reinforcement and the earth, a layer ...

Abstract

The invention relates to a construction method of an embedded hidden type soil nail combined with a basement exterior wall structure. The construction method comprises the following steps: 1, carryingout earthwork side slope construction; 2, carrying out soil nail slope surface groove construction; 3, spraying a first-layer rebar protective layer; 4, trepanning the soil nail; 5, mounting the soilnail and grouting; 6, mounting rebar meshes; 7, spraying concrete for the second time; 8, mechanically spraying a floated coat on the concrete sprayed for the second time; 9, paving and pasting waterproof roll as a waterproof layer on the floated coat; 10, carrying out waterproof protection layer construction on the waterproof layer; and 11, carrying out following basement exterior wall construction. According to the construction method, soil nailing wall supporting is utilized to serve as part of the basement exterior wall structure, so that the earthwork backfilling volume is reduced, the cost is lowered, the construction is convenient, the working efficiency is improved and the time limit for a project is shortened.

Description

technical field [0001] The invention relates to an embedded concealed soil nailing construction method, in particular to an embedded concealed soil nailing construction method combined with a basement exterior wall structure. Background technique [0002] There are various forms of soil nailing in China. In recent years, with the development of production and the expansion of urban construction scale, there have been more and more deep foundation projects, and the construction conditions have become more and more restricted. Soil nailing has been widely used in building construction due to its fast construction speed, simple construction equipment and process, convenient and flexible construction, irregular shape of excavation surface, slope slope, etc. The construction will not be affected, and the project cost is low. However, there must be an underground space on site that allows soil nails to be installed. If the soil nails are permanent, these underground spaces must b...
