Description
Technical field
This utility model relates to the realm of building construction, is a kind of prefabricated double-row pile foundation pit supporting construction integrated with water-stop curtain.
Background technology
The type of foundation pit supporting construction system is more, is respectively arranged with its scope of application.In terms of version, more employing campshed (wall)+inner support system (or outer anchor pole) in soft clay area.Wherein, what campshed was conventional is cast-in-situ bored pile, and inner support system mostly is monolithic reinforced concrete structure.Environment all can be caused large effect in work progress kind by these structures, and raw materials consumption is more, especially inner support system, in succession to remove and to clear up with construction progress, the series of processes such as the building waste of increase and cleaning.The gear soil then grown up and the shaped steel cement diaphragm wall (SMW engineering method) of water-stop curtain integration, canal formula cutting cement diaphragm wall (TRD engineering method) and derivative implantation prefabricated reinforced concrete I shape fender post wall technology (SCPW engineering method) etc. are all by inserting H profile steel in three axle cement mixing piles (for sealing), or the form of prefabricated reinforced concrete h pile reaches to keep off soil function.Due to by cement mixing pile machine operation, the soil disturbance in the range of stake footpath, so the concrete-pile inserting H profile steel or i shaped steel is just easier to, soil compaction phenomenon is the most weak, pile saving of labor saves material, wherein the most recyclable recycling of H profile steel, has certain economy.But these versions the most also need inner support system to support the use, and, although H profile steel can recycle and reuse, but when soil cement intensity is higher, Shaped steel recovery difficulty increases, and cost recovery also increases；In view of shaped steel one-time investment is relatively big, utilization rate is the highest, and existing market not yet forms charter business, so its economy inconspicuous.And prefabricated i shaped steel reinforced concrete does not reclaims, but production cost is much greater relative to prestressed concrete pipe pile, there is also economy problems.
And traditional Double-row-piles Structure form, owing to rigidity is big, it is little, as long as being with enough places outside foundation ditch to deform, during for deep basal pit, large area excavation, using this support form the most reasonable, but be the most often still to use inner support system, economy is not so good as campshed+inner support；And the way of pile is still based on cast-in-situ bored pile, so there is also economy and to deficiencies such as the adverse effects of environment.To this end, need existing foundation pit supporting construction and construction method are improved.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of prefabricated double-row pile foundation pit supporting construction integrated with water-stop curtain to this area, make it solve existing foundation pit supporting construction input cost relatively big, easily cause environmental pollution, and reclaim the technical problem of inconvenience.Its objective is to be achieved through the following technical solutions.
A kind of prefabricated double-row pile foundation pit supporting construction integrated with water-stop curtain, this foundation pit supporting construction includes double-row pile, truss-steel beam, Guan Liang, cement mixing method, wherein double-row pile refers to forward and backward two piles as unit, with this unit along forward and backward two campsheds of the evenly distributed formation of foundation ditch edge, and front campshed is positioned at the border of foundation ditch scope, rear campshed is positioned at the outside of foundation ditch scope；It is characterized in that the unit of described double-row pile refers to forward and backward two spaced concrete tubular piles, the described truss-steel beam of fixing connection between the top of two concrete tubular piles of each unit, and be connected for dismountable type between truss-steel beam with concrete tubular pile；The adjacent steel of described double-row pile is fixing between setting a roof beam in place connects described Guan Liang, and is connected for dismountable type between Guan Liang with truss-steel beam；Between the front-seat concrete tubular pile of described double-row pile, and between front-seat concrete tubular pile and heel row concrete tubular pile, described cement mixing method is set, i.e. forms water-stop curtain.Said structure is compared with prior art, major advantage is: double-row pile have employed concrete tubular pile, compare the solid concrete double-row pile that existing employing is precoated, or directly use prefabricated drum steel or insert the foundation pit supporting construction that the concrete-pile of H profile steel is formed, cost is relatively low, and truss-steel beam, the Guan Liang used is demountable structure design, thus detachable recovery after having constructed, recycle, it is substantially reduced construction cost, and dismounting assembles more convenient, reduce labor strength and difficulty of construction.
It is connected for hood type between described truss-steel beam and concrete tubular pile, i.e. truss-steel beam is formed by bolt locking by two parts, and be provided with inside truss-steel beam and the cranse of two concrete tubular pile corresponding anchor ear lockings in described unit, cranse is locked with two parts of described truss-steel beam and is locked with described concrete tubular pile.Or, it being provided with inside truss-steel beam and the cranse of two concrete tubular pile corresponding anchor ear lockings in described unit, cranse is provided with the bolt of regulation cranse coupling mechanism force.Hood type structure connects more reliable, and installing/dismounting is more convenient.
Described Guan Liang is truss structure, is bolted between Guan Liang and truss-steel beam.The assembly and disassembly of Guan Liang, truss-steel beam is facilitated by this structure.
Between each concrete tubular pile of front campshed of described double-row pile, and all it is independently arranged the Guan Liang fixing with described truss-steel beam between the rear each concrete tubular pile of campshed.This structure is conducive to improving the stability in the large of pattern foundation pit supporting structure.
Described concrete tubular pile is pretensioned prestressed concrete pipe pile, and concrete tubular pile pore in the pre-buried spacer bar in position flushed bottom described truss-steel beam, spacer bar upper support concrete bottom supporting plate.By this structure, the convenient pore to concrete tubular pile supplements and pours, to improve concrete tubular pile support strength and shear resistant capacity.
Between the two ends of the truss-steel beam that described double-row pile each unit is corresponding by presstressed reinforcing steel, anchorage, steering block formed prestressing force, the two ends of truss-steel beam arrange between front campshed and rear campshed in referring to double-row pile to two ends；Prestressing force is formed by presstressed reinforcing steel, anchorage, steering gear in described double-row pile between same row all truss-steel beams upwards.By Shi Hanzhang, and adjust prestressing force, make foundation pit supporting construction entirety more stable, firm.
This utility model has preferable economy, eliminates inner support and arranges, facilitates excavation of foundation pit；Truss-steel beam, Guan Liang are prefabricated structure, to job site non-environmental-pollution problem, and Guan Liang, the equal recoverable of rigit-frame beam, save material.Meanwhile, external prestressing adjustable, make foundation pit supporting construction deformation, stress more coordinate, it is safer, reasonable to use；The foundation pit supporting construction being suitable as construction uses, or the improvement of homogeneous structure.
