Abstract
The invention discloses an octagonal meshed water-stopping rectangular pile of a support. The rectangular pile comprises a pile body and a pile toe, anchor bars and construction bars are arranged on the pile toe, the pile body comprises an upper pile section, a middle pile section and a lower pile section, a pile cap and construction bars are arranged on the top of the upper pile section, and anchor bars are arranged at the lower end of the upper pile section; threaded anchor holes are formed in the upper end of the middle pile section, and anchor bars are arranged at the lower end of the middle pile section; threaded anchor holes are formed in the upper end of the lower pile section, and the pile toe is arranged on the lower part of the lower pile section; the section of the octagonal meshed water-stopping rectangular pile is octagonal. The octagonal meshed water-stopping rectangular pile has the advantage that the pile is widely applied to high bearing platforms, the condition that the pile is exposed on the ground and the condition with large stones. Meanwhile, the bars are evenly distributed through a long-line dado and a single mold, the bars integrally bear tension stress, the meshed water-stopping pile of the support is octagonal, and spiral stirrups are distributed. Long-line platform production can be carried out, labor is saved, the environment is protected, productivity is high, product quality is good, forming of tall and straight appearances of products is facilitated, and attractiveness and crack resistance are both good. The octagonal meshed water-stopping rectangular pile is suitable for water stopping of ports and piers and deep foundation pits, and is corrosion resistant and freeze thawing resistant.
Description
Technical field
The present invention relates to the realm of building construction, mainly refer to a kind of interlock water-seal pile and construction method thereof.
Background technology
In engineering construction field, along with being on the increase of high level, construction of super highrise building, in civil building engineering and Underground Engineering Excavation field, for in rivers estuary, a large amount of beach, district, groundwater table is higher, intensity is low, compressibilty is higher, the geology such as Muddy Bottoms opaque cohesive soil, a large amount of miscellaneous fill humus soils are major issues for deep pit digging supporting, sealing.Base pit engineering is an ancient tradition, puts the construction Rectangular Method that slope excavation and simple and easy timber are gone along with sb. to guard him, the needs of the Contemporary Architecture that is far from suitable construction, and its construction speed is slow, of poor quality, poor stability, cost is high, pollutes and weighs, waste goods, materials and equipments., in the supporting of subway engineering and highrise building foundation ditch, adopt hole-drilling interlocking pile at present at home and abroad more, though obtain successful experience, at excavation, supporting, how more to save, rapidly and efficiently, rationally in this problem, need to further study, inquire into.The drill-pouring concrete interlocking piles that adopt in current building excavation, support engineering more, although this interlocking pile can meet construction needs to a certain extent, but its difficulty of construction is larger, as many augers of need and a large amount of different bore steel sleeve, there is to very large restriction in stake footpath, the making of reinforcing cage more bothers, and very easily distortion, displacement.In concrete perfusion process, be difficult to control.Meanwhile, required time of concrete coagulation is longer, after interlocking pile pile, easily causes undergauge, spillage, reveals muscle, honeycomb, pitted skin, and main tendon protective layer thickness is difficult to ensure, finally causes leaking.The verticality of interlocking pile is also difficult to reach designing requirement.Reinforcing cage very easily floats in fluid concrete, has a strong impact on workmanship.And in construction underground excavation field, supporting, the sealing of large foundation ditch, because construction speed is too slow, have a strong impact on whole construction work progress, make engineering not expectability complete, cause very large economic loss to enterprise, affect the raising of Business Economic Benefit.
Summary of the invention
For solving the problems of the technologies described above, the invention provides following technology rectangle case:
