Abstract
Disclosed is a sand layer soil stiffener whose main body is a thin-wall steel tube. The head of the thin-wall steel tube is tapered. A grout outlet and a barb are distributed on the lateral wall of the thin-wall steel tube. The thin-wall steel tube can be arranged to have one segment or multiple segments according to the design depth. The connection between the segments can be screwed connection or inner liner tube welding connection. The disadvantage of a traditional soil nail when being used in the sand soil construction is solved by the utility model. Hole collapse during construction is avoided when the utility model is applied in the construction. The work is finished at one time, saving labor, materials and accelerating the construction speed; meanwhile, the nail-forming quality in the sand soil construction is ensured. The utility model is applicable to reinforcing the support sand layer position of the soil nail wall and the soil between the side slope piles in construction engineering.
Description
(1) technical field
The utility model relates to a kind of strenthening member of foundation pit stope support, particularly a kind of girth member that is applied in soil-nail wall support layer of sand position and the side slope inter-pile soil.
(2) background technology
In the foundation pit stope support engineering, adopt soil-nail wall support more.The general luoyang spade that adopts is earlier drawn the hole during soil nailing construction, after finish in hole to be drawn, adopt again and manually reinforcing bar is delivered to projected depth, but in work progress, if run into layer of sand, when manually sending reinforcing bar in addition to the hole wall disturbance, the regular hole of collapsing, wasted human and material resources, caused construction delay, the soil nailing difficult quality guarantee is brought great potential safety hazard.So traditional soil nailing construction technology is demanded urgently improving.
(3) utility model content
The purpose of this utility model provides a kind of layer of sand soil girth member, solve the easy hole of collapsing owing to adopt traditional soil nailing, often incurs loss through delay the problem of duration; Also to solve the problem that causes engineering safety hidden danger because of the difficult quality guarantee of soil nailing.
For achieving the above object, the utility model adopts following technical scheme: this layer of sand soil girth member, it is characterized in that: main body is a thin-wall steel tube 1, and its head is taper, is distributed with slurry outlet 4 and hangnail 3 on its sidewall.
Above-mentioned head 2 can be taper shape or pyramid.
Optimized technical scheme: the diameter of above-mentioned slurry outlet 4 can be 1.0～1.5cm.
Can be screwed connection or welding between above-mentioned thin-wall steel tube 1 and the head 2.
Above-mentioned thin-wall steel tube 1 is a joint or a plurality of sections of steel pipes screwed connection, perhaps, between joint and the joint internal lining pipe is arranged, and the junction is welding.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model has overcome the shortcoming of traditional soil nailing in the sandy soil construction, use the utility model hole phenomenon of in construction, can not collapsing, can disposablely survive, not only saved human and material resources, accelerate speed of application, also guaranteed the one-tenth nail quality in the sandy soil construction.Can be applicable to soil-nail wall support layer of sand position and the reinforcing of side slope inter-pile soil in the construction work.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an operating principle schematic diagram of the present utility model.
Among the figure: 1-thin-wall steel tube, 2-head, 3-hangnail, 4-slurry outlet, 5-cement paste post, 6-soil sidewall, 7-soil nailing metope reinforcing bar.
(5) specific embodiment
Embodiment is referring to shown in Figure 1, this layer of sand soil girth member, and it is characterized in that: main body is a thin-wall steel tube 1, its head 2 is taper shape or pyramid.Be distributed with the hangnail 3 of slurry outlet 4 and steel on the sidewall of thin-wall steel tube 1.The hangnail 3 of steel welds with the sidewall of thin-wall steel tube 1, and the diameter of above-mentioned slurry outlet 4 is 1.0～1.5cm.
Between above-mentioned thin-wall steel tube 1 and the head 2 for screwed connection or for the welding.Above-mentioned thin-wall steel tube 1 is a joint or a plurality of sections of steel pipes screwed connection; Perhaps, between joint and the joint internal lining pipe is arranged, the junction is welding.Thin-wall steel tube can adopt the scaffold tubes of φ 48 * 3 as main body.
Referring to Fig. 2, adopt hammering method that layer of sand soil girth member is used to sandy soil during construction earlier, when layer of sand soil girth member is used to into to predetermined depth the time, hangnail 3 is pricked in the native sidewall 6 fixing, inject cement paste from the afterbody of layer of sand soil girth member, the grouting pressure of afterbody is 2～3Mpa, formation has the cement paste post 5 of certain adhesion strength, in the sandy soil around cement paste penetrates into by slurry outlet 4, setting and harden, be connected as a single entity with sandy soil, at last soil nailing metope reinforcing bar 7 be connected with layer of sand soil girth member afterbody, thereby reach the effect of the stable side slope soil body.
