Description

A kind of high-strength prestressed concrete flute profile sheet pile
Technical field
The present invention relates to a kind of foundation pile, particularly relate to one and be used in architectural engineering and Structural Engineering High-strength prestressed concrete flute profile sheet pile.
Background technology
Urban skyscraper underground engineering excavation of foundation pit and supporting, dredging waterway shore protection dyke, road bridge During platform, railway slope of highway etc. are built, it is required for building retaining support structure.At present foundation ditch is propped up The method protected mainly has the method such as cast-in-situ bored pile, diaphram wall, and cost is high, man-hour is long.Part Project is also adopted by steel sheet pile as foundation pit supporting construction, and overall cost is higher, and anti-bending mechanics performance is subject to Limit.
Existing retaining support structure has following several:
(1) diaphram wall is suitable for full water soft stratum, such as full water sand bed, saturated soft mud Deng.In this type of soil layer, diaphram wall can intercept subsoil water effectively, but its cost is high, executes The work cycle is long, site operation and armored concrete pouring quality poor controllability, big on surrounding enviroment impact.
(2) cast-in-situ bored pile is to use campshed retaining support and waterproof of man waterproof, also due to on-the-spot Construction, quality control is unstable, and between stake, gap easily causes soil erosion, particularly soft at high water level Clayey area, need to according to engineering specifications take suitable working measure to solve dash problem, and stake and Between Zhuan main by stake apical cap beam with enclose purlin and be linked to be entirety, thus globality is poor.
(3) stake of SMW engineering method is the stiffness material being inserted into shaped steel or other kind at cement mixing method, Strengthen cement mixing method bending resistance, shear resistance.Although this kind of method is than construction of diaphragm wall speed Degree is fast, takes up an area few, and construction costs is more relatively low, but quality controllability is poor, and the cycle is long, and globality is not By force, later stage shaped steel pulls up stratum and environmental effect big, working-day claims and need secondary to mixing pile reinforcement.
(4) steel sheet pile is also conventional a kind of underground exterior-protected structure stake, and scantling and characteristic, it is not Being applicable to deep-foundation pit engineering, and its quantities is big, gear soil load performance does not has diaphram wall superior, Cost is higher relative to the flute profile concrete sheet-piling of patent of the present invention.
(5) conventional high-strength prestressed concrete sheet pile, changes traditional water conservancy engineering and uses making of material The shortcomings such as valency height, poor mechanical property, constructional difficulties, Forming Quality are unstable, have safe, attractive in appearance, Feature reliably.But due to its structural form, fourth of the twelve Earthly Branches mouth is little with tenon width, during piling, sheet pile unit Between easily produce that pile body concrete is damaged and the sealing adhesive tape damage of seam, thus cause its sealing Can be poor with globality, and the design of pile crown position easily causes work progress and crushes.
The invention provides and make, can be applicable to underground engineering Support of Foundation Pit Excavation, seashore loke shore river course Bank protection, Wharf Engineering construction, urban Underground pipeline, subway station construction, roadbed bank protection gear soil, bridge Beam culverts abutment bank protection gear soil, for small bridge at the same time as building enclosures such as bearing piers, Simultaneously and convenient later maintenance, quick, simple.
Summary of the invention
It is an object of the invention to provide a kind of height using pretensioned prestressing high strength RC material Intensity prestressed concrete flute profile sheet pile, optimizes sheet pile mechanical property, sheet pile when strengthening piling further Stationkeeping ability between unit, improves stagnant water effect and globality.
For achieving the above object, the technical scheme is that a kind of high-strength prestressed concrete Flute profile sheet pile, the pile body made including armored concrete, pile body cross section is flute profile, described pile body two It is respectively equipped with the first linkage section and the second linkage section, the first linkage section and the second linkage section outside sidewall to divide Not being provided with the first connecting portion and the second connecting portion that matching form closes, described first connecting portion coordinates face to set The first sealed groove, described second connecting portion is had to coordinate relevant position, face to be provided with the second sealed groove, institute State the first sealed groove and the second sealed groove cooperatively forms an annular seal space, in annular seal space, fill sealing material Material.
As a kind of optimal way of the present invention, encapsulant selects cement mortar or other waterproof serosity to fill out Material.
Further, there is in the middle part of described first connecting portion a groove, corresponding to described first connecting portion, There is in the middle part of described second connecting portion a projection corresponding with described groove, described first connecting portion Described groove cooperates with the projection of described second connecting portion.
Further, along being perpendicular to described channel-section direction in described pile body, it is equipped with many reinforcing bars, Adjacent reinforcing bar passes through stirrup colligation, and described stirrup is that netted colligation is on main muscle.
Further, described stirrup take-up strap is on main muscle.
The invention has the beneficial effects as follows:
Use pretensioned prestressing high strength RC material to make, can be applicable to underground engineering foundation ditch Excavation supporting, seashore loke shore river course slope protection, Wharf Engineering construction, urban Underground pipeline, subway station Build, roadbed bank protection gear soil, the bank protection of bridge culvert abutment keep off soil, can make for small bridge simultaneously For building enclosures such as bearing piers, simultaneously and convenient later maintenance, quick, simple.
