Description
Technical Field
The utility model relates to a foundation ditch engineering field, concretely relates to formula stake wall supporting construction system is beaten in many antithetical couplets.
Background
With the development of underground space becoming more and more powerful, the application of foundation pit support in engineering becomes more and more extensive. Due to the complexity of geotechnical engineering itself, and often with complex surrounding environments: underground pipelines, peripheral roads, buildings and the like sometimes occur in accidents related to foundation pit support safety, and negative influence and economic loss are caused to the society. Through statistical analysis, the underground water causes the foundation pit engineering dangerous case to account for a larger proportion of the accidents.
In deep foundation pit supporting engineering, the more common supporting forms mainly comprise three forms, namely a row pile and a waterproof curtain supporting form, the supporting effect mainly depends on whether the waterproof curtain meets the design requirement, and the pile forming effect is limited by factors such as geology, construction level and the like, so that the foundation pit water leakage phenomenon often occurs, and even safety accidents are caused; secondly, the interlocking row pile supporting form adopts the mutual interlocking of meat and vegetable piles, so that the problem of unstable pile forming quality of mixing piles, high-pressure jet grouting piles and the like is solved, the water stopping effect is improved, but the contact surface between piles is more, the pile forming verticality requirement is higher, and the problem of water leakage caused by insufficient lap joint length between piles due to the problem of water leakage of the contact surface is easy to occur or the problem of water leakage caused by insufficient lap joint length between piles due to the verticality is solved; and thirdly, the underground continuous wall is in a supporting mode, the whole wall is formed, the number of the contact surfaces of the wall and the wall is small, the quality is easy to control, the underground continuous wall is widely applied to ultra-deep foundation pits or complex foundation pits, and the comprehensive cost is high. How to save the engineering cost and ensure the safety of the foundation pit under the condition of ensuring the water stopping effect is worthy of being explored by engineering personnel.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a formula stake wall supporting construction system is beaten in many stake antithetical couplet, its structure is firm reliable, and the stagnant water is effectual, and construction convenience synthesizes and uses the steel volume few, can solve some complicated deep basal pit support problems.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a formula stake wall supporting construction system is beaten to many stake antithetical couplets which characterized in that: the foundation pit supporting structure comprises a plurality of wall grooves which are continuously and hermetically arranged along the periphery of a foundation pit, a plurality of supporting members are placed in the wall grooves and are arranged at intervals, plain concrete is poured in the wall grooves and is filled in the wall grooves, and the plain concrete and the supporting members are combined to form a stressed structure of a foundation pit supporting system.
Preferably, the high-pressure jet grouting piles are arranged at the joints of the two adjacent wall grooves, and water stopping at the joints of the wall grooves and the wall grooves can be enhanced through the high-pressure jet grouting piles.
Preferably, the supporting member is a member with similar functions such as a row pile reinforcement cage or a precast pile or a steel pile.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a wall formula grooving and place the supporting member in the wall inslot, both absorbed whole width of cloth finished wall of underground continuous wall, the contact surface is small in quantity, and the stagnant water is effectual, and advantages such as straightness easy control that hangs down have absorbed the supporting member simultaneously, for example arrange pile steel reinforcement cage or precast pile or piling bar etc. arrange in a flexible way, hoist and mount conveniently, synthesize with advantages such as the steel volume is few, the engineering is strutted to some complicated deep basal pits of specially adapted.

The utility model provides a formula stake wall supporting construction system is beaten in many antithetical couplet, include along the peripheral wall groove 1 that sets up in succession of foundation ditch, set up at the wall inslot strut member and pour the plain concrete 3 at the wall inslot.
The supporting member in this embodiment is the row pile reinforcement cage 2, and in actual construction, other members with similar functions, such as prefabricated columns, steel columns and the like, can be selected as the supporting member.
As shown in fig. 1, the wall slots 1 are continuously arranged along the periphery of the foundation pit, six rows of pile cages 2 (or precast piles, steel piles, etc.) are placed in each wall slot 1, and the pile cages 2 (or precast piles, steel piles, etc.) are arranged at certain intervals; and plain concrete 3 is poured to fill the wall groove 1 and is combined with the pile arrangement reinforcement cage 2 (or precast piles, steel piles and the like) to form a stressed structure of a foundation pit supporting system.
The utility model discloses still set up high pressure jet grouting pile 4 at seam crossing between adjacent wall groove 1 and the wall groove 1, can effectively strengthen the stagnant water of wall groove 1 and 1 seam crossing in wall groove through high pressure jet grouting pile 4.
The utility model discloses compare prior art, beneficial effect lies in adopting wall formula grooving and placing campshed steel reinforcement cage 2 (or precast pile, piling bar etc.) in wall groove 1, has both absorbed the whole wall of underground continuous wall, and the contact surface is small in quantity, and the stagnant water is effectual, and straightness advantage such as easily control hangs down has absorbed campshed steel reinforcement cage 2 (or precast pile, piling bar etc.) simultaneously and has arranged in a flexible way, hoist and mount conveniently, synthesizes with advantages such as the steel volume is few, the engineering is strutted to some complicated deep basal pits of specially adapted.
