Embodiment Construction

[0050] The following is attached Figure 1-3 The application is described in further detail.

[0051] The embodiment of the present application discloses a construction technology of soil nailing wall support, referring to figure 1 and figure 2 , the technical steps of the soil nailing wall support construction technology are as follows:

[0052] S1. Earth excavation:

[0053] S11. Excavation of foundation pit: Excavation combined with mechanical and manual slope repair is adopted. During the mechanical excavation, the underexcavation amount is not more than 100mm. Excavation, measure the slope and flatness of the slope after the excavation is completed;

[0054] S12. Manual excavation of weep holes and drainage ditches 1: According to the geological seepage situation and the construction requirements of weep holes, manually excavate weep holes, every 8m of weep holes 2 -12m 2 Open one, if the geological seepage is high, increase the number of weep holes, and excavate d...

Abstract

The invention relates to the field of road construction, and particularly relates to a soil nailing wall support construction process. The soil nailing wall support construction process comprises the following process steps of S1, earth excavation; S11, foundation pit excavation; S12, manual excavation of a water drainage hole and a water drainage ditch; S13, water guide pipe installation; S2, concrete spraying; S3, soil nailing hole forming; S4, soil nailing installation; S41, inspection before construction; S42, positioning support installation; S43, soil nailing placement; S5, grouting; S6, reinforcement mesh weaving and hanging; S7, connecting rib welding; S8, concrete plate wall spraying; and S9, maintenance. Through the excavation of the water drainage hole, the concentrated discharge of underground water is convenient; the erosion of the underground water on the soil nailing wall is reduced; meanwhile, the seeped underground water is discharged in a concentrated way; and the integral quality of the soil nailing wall is improved.

Description

technical field [0001] The application relates to the technical field of fan production, in particular to a construction technique for soil nailing wall support. Background technique [0002] Soil nail wall is an in-situ soil reinforcement technology. The slope of the foundation pit is reinforced by soil nails made of steel bars. A steel mesh is laid on the surface of the slope, and a layer of concrete surface is sprayed to combine with the earthwork slope. Slope reinforcement type support construction method. [0003] The Chinese patent with the application number 201910909228.5 discloses a recyclable soil nail wall support structure and construction technology. The support structure includes; a protective layer, which is laid on the slope of the soil nail wall; Each of the fixing parts is connected in the soil nail wall through the protective layer, and a plurality of the fixing parts are distributed at intervals on the slope of the soil nail wall; a plurality of connecti...
