Abstract
The utility model relates to a soft soil area composite soil nailing wall and aims at providing the soft soil area composite soil nailing wall which is simple in structure and convenient to construct and low in construction cost, and enhances stability and reliability of a foundation pit. The technical scheme includes that the soft soil area composite soil nailing wall comprises the foundation pit with a digging depth of 4 meters to 6 meters in a soft soil area. The edge of the foundation pit is provided with a step-shaped side slope with proportion of a slope degree being one to one. Soil nails used for reinforcing are buried in the side slope. The side slope is characterized in that a row of supporting piles is vertically constructed downward on a slope foot portion of the side slope, the supporting piles and the adjacent soil nails are distributed at intervals and fixed together, and cement stirring piles are arranged in a casting mode on the supporting piles close to the pit bottom side and attached to the supporting piles tightly. The soft soil area composite soil nailing wall is suitable for soft soil foundation pit projects.
Description
Technical field
The utility model relates to a kind of soft clay area composite soil nailing wall.Be applicable to the soft soil foundation pit engineering.
Background technology
Soft clay area is dug the foundation ditch about dark about 5m; Because it is relatively poor that its economy of rigidity supporting and protection structure such as drilled pile is set; Surrounding enviroment are not under the situation of harshness especially; Present this foundation ditch to be adopted and puts the slope and combine timber or steel sheet pile, soil nailing wall, composite soil nailing wall etc. to go along with sb. to guard him pattern, and wherein many to combine two row's agitation piles to form upright excavation face with soil nailing be main to composite soil nailing wall.Which kind of pattern no matter though designing and calculating can be passed through, in the construction of reality, tends to occur dangerous situations such as landslide at present.Make soft clay area, the foundation ditch about 5m become and a higher field of dangerous situation rate.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence, a kind of simple in structure, easy construction, soft clay area composite soil nailing wall that construction cost is low are provided, strengthen the stable and reliability of foundation ditch.
The technical scheme that the utility model adopted is: a kind of soft clay area composite soil nailing wall; Have soft clay area and dig deeply foundation ditch at 4 ~ 6 meters; The edge of said foundation ditch is provided with the stairstepping side slope of gradient 1:1, is embedded with the soil nailing that is used to reinforce in the side slope, it is characterized in that: the toe place injection straight down supporting pile in a row of said side slope; Supporting pile and adjacent soil nailing separation are also fixed with soil nailing, said supporting pile by the bottom side, hole, be close to supporting pile and built cement mixing pile.
Said soil nailing both sides up and down is fixing through elongated horizontal reinforcement and supporting pile welding, and the left and right sides is fixing with soil nailing and horizontal reinforcement welding respectively through vertical reinforcing bar.
Lay the two-way concrete slab net on the said side slope surface and watered injection concrete mask.
Said supporting pile adopts pine stake or steel sheet pile.
Said foundation ditch periphery has been built a circle gutter.
The beneficial effect of the utility model is: through soft clay area is improved than shallow foundation hole (digging dark about 5m) soil nailing wall; Adopt soil nailing, supporting pile and passive area soil stabilization (joints cement agitation pile) three's synergy; Form a kind of NEW TYPE OF COMPOSITE soil nailing wall structure; Effectively solve the supporting problem of soft clay area, under the prerequisite that guarantees foundation ditch safety during the excavation, taken into account economy than the shallow foundation hole.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is an A portion enlarged drawing among Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, present embodiment is intended and is excavated the foundation ditch 1 of a degree of depth about 5 meters in soft clay area, and the edge of this foundation ditch 1 is provided with the trapezoidal side slope 2 that the gradient is 1:1, and side slope 2 adopts soil nailing 5 to reinforce.Toe place injection straight down one row's of said side slope 2 supporting pile 4; Supporting pile 4 adopts steel sheet pile in the present embodiment; Steel sheet pile and adjacent soil nailing 5 separation, the elongated horizontal reinforcement 8 of upper and lower both sides welding of soil nailing 5, and horizontal reinforcement 8 is fixing with the steel sheet pile welding; Soil nailing 5 and arranged on left and right sides weld lengths are the vertical reinforcing bar 9 of 150mm, and vertical reinforcing bar 9 two ends and horizontal reinforcement 8 welding formation one groined type support.For improving the stability and the safety of foundation ditch 1, the foundation ditch passive area soil body is reinforced, supporting pile 4 near hole one side at the end, be close to supporting pile 4 joints cement agitation piles 3.
Excavation slope 2 domatic upward laying two-way concrete slabs also water to establish and spray concrete mask 6, on the surrounding ground of foundation ditch 1, are provided with a circle gutter 7.
