Embodiment Construction

[0036] Examples see figure 1 , figure 2 with Figure 4 As shown, a full-thread fiber resin rod body soil nail wall includes a slope soil body 10, a concrete surface layer 9 and a soil nail 1 formed by spraying concrete slurry, and the soil nail 1 includes a rod body, a backing plate and a tightening nut , the rod body is inserted into the slope soil body 10, the hole between it and the slope soil body 10 is injected with the rod peripheral slurry 8, the outer end of the rod body is tightened by a nut to fix the backing plate, the pad The plate pad is between the tightening nut and the concrete surface layer 9, and the outer surface of the slope soil 10 is laid with a steel mesh 4, and the concrete surface layer 10 wraps the steel mesh 4, and it is characterized in that: the rod body is fully threaded Fiber resin rod body 1.1, which is located in the upper part of the inner section of the concrete surface layer 9, is provided with auxiliary reinforcing ribs 5, and the lower ...

Abstract

The invention relates to a full-thread fiber resin rod body soil nailing wall and a construction method thereof; a soil nail rod body of a soil nailing wall is a full-thread fiber resin rod body, auxiliary reinforcement ribs are arranged at positions situated on the upper part of an interior segment of a concentrate surface layer of the soil nail rod body, and continuous cross pressing ribs are arranged on the lower part thereof; the fastening nut is a resin nut; the lining plate is a resin lining plate injected by a resin material and is fastened on the outer surface of the concentrate surface layer; and ring locators are sleeved on the parts stretched into the side slope soil of the full-thread fiber resin rod body at intervals. Compared with the present soil nailing wall, the invention has the advantages of simple and convenient construction, energy saving, consumption reduction and larger application range of resin rod body; and the nut and lining plate situated on the end part of the rod body are situated at the outside of the concentrate surface layer, so the stress is more reasonable. Meanwhile, an expanding head is arranged at a position situated in the side slope of the rod body according to the actual engineering to form a reinforced expanding head soil nail, so that the plasticity is strong. The invention can be extensively applied in the construction of side slope soil nailing wall technique.

Description

technical field [0001] The invention relates to a soil nail wall and a construction method thereof, in particular to a soil nail wall in which a fully threaded resin rod body is used instead of a steel bar as the main reinforcement of the soil nail and a construction method thereof. Background technique [0002] In foundation pit support engineering, soil nail wall support is a more commonly used support method. The soil nail generally uses rebar as the main reinforcement of the soil nail. Concrete finish. This support system has the following disadvantages: (1) It is easy to fail due to corrosion of the soil nail reinforcement; (2) The welding process is required to process the rod body and the concrete surface; (3) The soil nail anchor head is placed on 8-10cm thick concrete In the surface layer, the joint stress effect of the concrete surface layer and the anchor head cannot be fully utilized; (4) The reinforced soil nails embedded in the soil layer form obstacles in the...
