Abstract
The utility model designs a slop face supporting structure, which particularly relates to a soft soil foundation pit soil nail supporting structure. The soft soil foundation pit soil nail supporting structure comprises soil nails and a concrete layer. The soil nails are embedded in the side slope of a foundation pit. The exposed ends of the soil nails are provided with a reinforcing bar net on which the concrete layer is sprayed. The soil nail is made of moso bamboo. The moso bamboo is adopted to be the round pipe soil nail. The construction is convenient and quick, the displacement and sedimentation of the side slope of the foundation pit is stable and the support is reliable. The time of the temporary supporting action is far longer than the construction time of the foundation pit, which can keep the construction safe. The moso bamboo is annual plant, which has the advantages of low cost, convenient material obtaining, saving steel, protecting mineral resources and according with environmental protection requirement.
Description
Technical field
The utility model designs a kind of domatic supporting and protection structure, relates in particular to a kind of soft soil foundation pit plate brad supporting structure
Background technology
The latter stage fifties, the use by soil bolt made soil-baffling structure that new development arranged, and utilized soil bolt that it is carried on the back to draw formation anchor rod type barricade thereby build earlier stake, diaphragm wall, sheet pile etc. before excavation of foundation pit.Occurred anchor pole structure wall after 10 years, it is to utilize the concrete member to be arranged in soil layer surface in the digging process, carries on the back with anchor pole and draws, and this is a kind of mode that can carry out operation with excavation works simultaneously.
Reinforced earth wall has appearred the sixties, general in the embankment district as the retaining wall of building the road, embankment zone in smooth place forms, layering lay geotextile and in prefabricated concrete panel drawknot when the back-filling in layers earthwork forms reinforced earth bulkhead.
The soil nailing wall is to be reinforced on the spot by the soil nailing wall and combined with spraying the concrete panel by the natural soil body, forms a similar gravity barricade and comes soil pressure after the resistance wall with this; Thereby keep the stable of excavation face, this native barricade is called the soil nailing wall.The soil nailing wall technology is used in China and is started from the beginning of the eighties, because that it has a material usage is few, speed of application is fast, and is safe and reliable, the economic dispatch advantage, and this technology is more and more used in retaining wall and the anti-excavation of base at present.
Existing soil nailing wall generally is provided with by boring, joint bar, slip casting, also can directly squeeze into angle steel, bar reinforcement formation soil nailing.Need boring, joint bar, slip casting owing to adopt, and need maintenance, it is cumbersome therefore to construct, and the duration is longer relatively, and it is high that the relative mao bamboon joint bar of cost is wanted.
Summary of the invention
The technical problem that solves:
The utility model provides a kind of soft soil foundation pit plate brad supporting structure, has solved above-mentioned reinforcing bar soil nailing cost height, and construction technology is complicated and need maintenance costs than problems such as height.
The utility model is the technical solution problem by the following technical programs:
The utility model is a kind of soft soil foundation pit plate brad supporting structure, comprises soil nailing, layer of concrete; Described soil nailing is embedded in the excavation slope, arranges steel mesh reinforcement, shotcrete layer on the reinforcing bar wire side at the end of appearing of soil nailing; The bamboo one-tenth of described soil nailing hairiness.
Soft soil foundation pit plate brad supporting structure described in the utility model, the diameter 〉=50mm of described soil nailing.
Soft soil foundation pit plate brad supporting structure described in the utility model, the length 〉=5.0m of described soil nailing.
Beneficial effect
Adopt mao bamboon as the pipe soil nailing, convenient and quick construction, the displacement of excavation slope and settlement stability, supporting is reliable, and temporary lining is longer than far away the foundation pit construction time action time, can guarantee that construction safety carries out.Mao bamboon is annual living plant, and cost is low, draws materials conveniently, saves steel, protection mineral resources, compliance with environmental protection requirements.
Description of drawings
Fig. 1 is the utility model structural representation
1 is soil nailing, the 2nd among the figure, layer of concrete.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: soft soil foundation pit plate brad supporting structure comprises soil nailing 1, layer of concrete 2; Described soil nailing 1 is embedded in the excavation slope, arranges steel mesh reinforcement at the end of appearing of soil nailing 1, and shotcrete layer 2 on the reinforcing bar wire side; Described soil nailing 1 is made by mao bamboon.
Be inserted with many mao bamboon soil nailings 1 in excavation slope, the steel mesh reinforcement that is located in the excavation slope jet surface concrete pavement 2 is then fixedlyed connected with the pipe soil nailing end of exposing.The mao bamboon top diameter requires greater than 50mm, and length is not less than 5.0m, adopts excavator directly to be pressed into.The level of bamboo reinforcement and vertical spacing are determined according to calculating.The domatic employing linked network of soil nailing wall pneumatically placed concrete is handled, linked network muscle φ 6.5@200 * 200, soil nailing are connected with surface layer with 4 Φ 16, and long 400 groined type reinforcing bar welding also is pressed on the steel mesh reinforcement, same casting is followed closely level to employing 2 Φ 16 elongated strengthened connection bars, and firm with steel wire lashing with mao bamboon.
