Description
Technical field
The utility model is related to technical field of civil engineering, specifically a kind of prefabricated T-shaped sheet pile foundation pit enclosure knot
Structure.
Background technology
It is a kind of important feature form of foundation pit enclosure using campshed building enclosure in base pit engineering or slope project, exists
It is from all parts of the world extensively to apply, shaped steel Soil-cement Wall etc. of the current campshed frequently with bored pile or SMW engineering methods.
Bored concrete pile meant in engineering site by mechanical hole building, mud off, forms stake holes in foundation soil, and in which
Steel reinforcement cage, in-site pouring concrete and the stake that formed is placed, different according to forming hole method, bored concrete pile can be divided into punching again and irrigate
Several classes such as stake, cast-in-situ bored pile and digging hole filling pile.The construction of cast-in-situ bored pile, because of the difference of forms of protective wall selected by which, has mud
Slurry retaining wall mode and a complete set of two kinds of pipe construction.Constructed bored concrete pile pole using mud off mode in soft soil layer and unstable soil layer
The common faults such as constriction, collapse hole, stake holes deflection are also easy to produce, so as to affect concrete placed under water quality, and a large amount of circulations can be produced
Mud, causes environmental pollution；Although full-sleeve construction technology can avoid mud off, because by casing length and run of steel
Affect, difficulty of construction is big, and high cost, speed are slow.
The shaped steel Soil-cement Wall of SMW engineering methods, will H profile steel or steel pipe be inserted in Soil-cement Wall, will bear
Both load and antiseepage dash combine, make and meanwhile have carry and impervious two kinds of functions supporting construction.For reducing
Construction costs, the H profile steel or steel pipe being commonly inserted at present are both needed to extract recovery, therefore in its external coating antifriction material, but
Antifriction material have impact on the bond strength of shaped steel and soil cement, while soil cement water-stop curtain during shaped steel is inserted out, can be destroyed,
Produce the space of certain volume simultaneously again, disadvantageous deformation etc. is produced on the protection object for closing on affects.
Therefore engineering circles are needed badly and find a kind of advantage that can commonly use campshed building enclosure with reference to both the above, can be overcome again
The new supporting pile structure of its deficiency, but the shaping due to precast reinforced concrete pile and connectivity problem do not solved well
Certainly, this new supporting pile structure is made to be difficult to obtain practical application effect.
Utility model content
Technical problem to be solved in the utility model be overcome hole quality present in existing bored concrete pile technology compared with
Difference, under water cast-in-place concrete pile body intensity are difficult to control to, and produce a large amount of mud and are difficult to back to polluting environment, SMW engineering method Shaped Steels
Receive and the problems such as removal process is deformed, construction period is longer, there is provided a kind of prefabricated T-shaped sheet pile foundation pit enclosure structure.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：
A kind of prefabricated T-shaped sheet pile foundation pit enclosure structure, is provided with T-shaped sheet pile in the self-solidifying stream modeling soil body, and T-shaped sheet pile is longitudinally spelled
Connect and be connected with Guan Liang；The T-shaped sheet pile is the prefabricated standard component of modularization；Modular connection is connected between standard component；Connect
Head includes horizontal joint and vertical joint；Horizontal joint is mechanically connected for screw lock formula, and vertical joint is the enterprise of embedded sealing adhesive tape
Mouth joggle.
T-shaped sheet pile is real abdomen or cavity member, forms using high-strength concrete and high-strength steel bar are prefabricated；Component is adopted first to be opened
Method applies prestressing force.
The horizontal joint of T-shaped sheet pile fills high-strength resin material on composition surface.
Multiple of the T-shaped sheet pile standard component length modulus for 2m, maximum length 16m；Cross-sectional width be 2.8,2.5,2.1,
1.8th, 1.5m, depth of section be 2.0,1.8,1.5,1.2,1.0m.
T-shaped sheet pile is embedded with connecting screw hole on top, is easy to Guan Liang bar connecting and anchors in Guan Liang.
Beneficial effect：The utility model is by being implanted into the T-shaped plate of spreading in outside self-solidifying mud or stream plastic solidified soil
Stake is carried out longitudinal spliced and be connected with Guan Liang and combine, and has gear soil and water stopping function concurrently, and alternative existing piling wall of going along with sb. to guard him is tied
Structure.The utility model site operation is workable, component assembling degree high, operating efficiency is high, ensure that the whole of structure
Body and construction quality, reduce construction costs, and engineering construction works well.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the T-shaped sheet pile horizontal layout of the utility model and vertical joint schematic diagram；
Fig. 2 is the T-shaped sheet pile facade of the utility model and horizontal joint schematic diagram.
In figure：The 1 outside self-solidifying stream modeling soil body, 2 T-shaped sheet piles, 3 vertical joints, 4 tongue and groove joggles, 5 water-stop glues
It is bar, 6 horizontal joints, 7 screw lock formulas mechanical connection, 8 high-strength steel bars, 9 screw lock steel bushings, 10 screw lock connecting rods, 11 high
