Abstract
The utility model discloses a can be according to local conditions abutment underground structure who reduces engineering volume, foundation ditch bottom surface escape canal all around converges in the sump pit, supporting structure includes the stone enclosure wall of establishing of building all around in the inboard foundation ditch bottom surface in escape canal to be provided with the isolation layer at the outer wall of stone enclosure wall, the isolation layer is made with plastic film. The supporting materials are made of local materials, stones at the position of the foundation pit are utilized by the pile, the pile does not need to be transported, the construction is convenient, and the environmental pollution is avoided; the integral stability of the stone enclosing wall is good, and the size of a basic structure is protected; the construction technology difficulty is low, other horizontal and longitudinal supports or special support equipment are not needed to complete foundation pit support, and the restriction of the geographical construction environment is small; the cost is low, the construction is safe, and the construction progress is fast. The method is particularly suitable for deep foundation pits with the depth of more than 4m or application under geological conditions with poor stability.
Description
Technical field
The utility model relates to a kind of foundation pit supporting construction, especially a kind of Foundation Pit of Abutment supporting and protection structure.
Background technology
For the abutment construction, foundation ditch structure commonly used is a piling strtucture, and stake is irritated in piling earlier again, and its advantage is to save the concrete square amount, saves cost.But place at some geology poor stabilities, when being cobble, sand gravel, erratic boulder layer etc. as the foundation ditch retaining wall, quicksand, infiltration take place easily, the foundation ditch retaining wall easily collapses, at this moment, if re-use existing piling strtucture abutment, will cause the supporting difficulty, the concrete structure size is occupied easily, just must increase excavated volume, the also corresponding increase of backfill amount, claim for eot, cost increases.
The utility model content
For the bigger deficiency of Foundation Pit of Abutment supporting and protection structure engineering quantity under the geological conditions that overcomes existing geology less stable, technical problem to be solved in the utility model provides a kind of Foundation Pit of Abutment supporting and protection structure that can suit measures to local conditions to reduce engineering quantity.
The technical scheme that its technical problem that solves the utility model adopts is: Foundation Pit of Abutment supporting and protection structure, gutter around the foundation ditch bottom surface is compiled in sump, described supporting and protection structure is included in the foundation ditch bottom surface of inboard, gutter and builds the stone fence of establishing all around, and is provided with separation layer at the outer wall of stone fence.
Described separation layer is made with plastic foil.
The beneficial effects of the utility model are: support material is gathered materials on the spot, and the stone of foundation ditch position obtains this utilization, does not need transhipment, and easy construction does not have environment pollution; The resistance to overturning of stone fence is good, has protected foundation structure thing size; The horizontal stroke that construction difficulty is low, do not need other, vertical support or special support apparatus is finished pattern foundation pit supporting structure are subjected to the restriction of geographical construction environment less; Low, the construction safety of cost, construction speed is fast.Being particularly suitable for the degree of depth uses under deep foundation ditch more than the 4m or the geological conditions in less stable.
Description of drawings
Fig. 1 is the elevation of the utility model supporting and protection structure.
Fig. 2 is the plan view of the utility model supporting and protection structure.
Be labeled as 1-foundation ditch bottom surface, 2-stone fence, 3-separation layer, 4-gutter, 5-sump among the figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1 and Figure 2, the gutter 4 around the foundation ditch bottom surface 1 is compiled in sump 5, and Foundation Pit of Abutment supporting and protection structure of the present utility model is included in the foundation ditch bottom surface 1 of 4 inboards, gutter and builds the stone fence of establishing 2 all around, and is provided with separation layer 3 at the outer wall of stone fence 2.The function of stone fence 2 has two; the one, as the supporting retaining wall; the 2nd, as the template that build on the basis, stone fence 2 is as the supporting of foundation ditch, good stability own; the template of double as base concrete cast; also can satisfy instructions for use, thereby can reduce excavated volume and backfill amount, spread separation layer 3 in stone fence 2 outsides; isolation may be protected basic works size from the inside quicksand that immerses of outer wall.In addition, this stone fence 2 can originally just exist the gravel stone to build by laying bricks or stones in the foundation ditch position, reduces transhipment, and the cost of material is low.
Described separation layer 3 can be made by plastic foil, can take off after to be cast the finishing to reuse, and has both reduced environment pollution, saves cost again.The material that also can use other quality densification can prevent that quicksand from immersing is made separation layer 3.
Claims (2)
1. Foundation Pit of Abutment supporting and protection structure, gutter (4) all around, foundation ditch bottom surface (1) is compiled in sump (5), it is characterized in that: described supporting and protection structure is included in inboard foundation ditch bottom surface (1), gutter (4) and builds the stone fence of establishing (2) all around, and is provided with separation layer (3) at the outer wall of stone fence (2).
2. Foundation Pit of Abutment supporting and protection structure as claimed in claim 1 is characterized in that: described separation layer (3) is made with plastic foil.
