Description
Technical field
The present invention relates to technical field of civil engineering, a kind of foundation ditch and the vertical building enclosure of side slope.
Background technology
The piling wall type building enclosure used in base pit engineering or slope project is a kind of important feature shape of foundation pit enclosure
Formula, extensively applies in all parts of the world, and current foundation ditch and side slope go along with sb. to guard him piling wall frequently with boring (rotation is dug) perfusion post, SMW
The shaped steel Soil-cement Wall of engineering method, prefabricated pile Soil-cement Wall and cast-in-place diaphram wall etc..
Bored concrete pile means at engineering site by mechanical hole building, mud off, formation stake holes in foundation soil, and within it
Placing steel reinforcement cage, in-site pouring concrete and the stake that formed, different according to forming hole method, bored concrete pile can be divided into again punching to 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 it, has mud
Slurry retaining wall mode and full-sleeve are constructed two kinds.Soft soil layer and unstable soil layer use mud off mode construct bored concrete pile pole
It is easily generated the common faults such as constriction, collapse hole, stake holes deflection, thus affects the quality of concrete placed under water, and generation circulates mud in a large number
Slurry, the discharge of mud and process will result in environmental pollution；Although full-sleeve construction technology can protect stablizing of hole wall, but still not
Can avoid completely using mud to carry out the Water And Earth Pressures at the bottom of balance pipe, owing to being affected by the solid element such as hole depth, casing length, difficulty of construction
Greatly, cost is high, and speed is slow.
The shaped steel Soil-cement Wall of SMW engineering method, H profile steel or steel pipe will be inserted in Soil-cement Wall, will bear
Load combines with antiseepage dash, makes the supporting construction simultaneously having carrying with two kinds of functions of sealing.For reducing
Construction costs, the H profile steel being commonly inserted at present or steel pipe are both needed to extract recovery, the most all at its external coating antifriction material, but
Antifriction material have impact on the bond strength of shaped steel and soil cement, can destroy soil cement water-stop curtain during shaped steel is inserted out simultaneously,
And produce the space of certain volume, cause deformation unfavorable to the environmental conservation closed on.
Steel sheet pile enclosure structure, employing is the Larsen steel sheet pile of band occlusion, is engaged by the fore shaft on stake limit and forms entirety, shape
Become assembled building enclosure.But due to its length and the restriction of cross dimensions, it is only used for excavating shallower foundation ditch, as the degree of depth is little
In the foundation pit enclosure of 6m.Owing to its bending rigidity is less, the deformation that stress produces is relatively big, in more important environmental conservation region
Should not use.
Soil cement is inserted into the building enclosure of pile for prestressed pipe or square pile, has gear soil and the double effects of sealing.Due to
The joint of its prefabricated pile connects strong ties such as being difficult to, or joint connection construction is the most complicated, up to the present, and can only be with single
The prefabricated pile of joint is less than 15m as foundation pit enclosure structure, the long maximum of single-unit stake, uses the foundation ditch of this building enclosure or side slope deep
Degree also only has 6～8m, it is clear that receiving by range of application of this building enclosure necessarily retrains.Even if the interconnection technique of joint is asked
Topic solves, but to determine its bending resistance limited due to the cross section property of current pile tube or square pile, it is difficult to reach more rational
Supporting benefit.

Concrete pouring quality problem, thus produce surface dew muscle and hole, body of wall and joint localized seepage, wall steel bar basket structure
The wall body mass defects such as damage, affect safety and the waterproof effect of continuous underground wall structure.
Continuous wall trench underground process typically uses mud to carry out retaining wall, needs to discharge mud, produce after casting concrete
Substantial amounts of waste mud needs to process, and causes the increase of serious environmental pollution and cost.
The construction property of diaphram wall underwater casting determines job site and is difficult to ensure that the construction quality of body of wall, and this is also
It is the cast-in-place continuous underground wall structure mass defect that is difficult to improve or make up.Therefore, engineering circles need badly searching one can substitute
The Novel underground diaphragm wall structure of cast-in-place diaphram wall, but this industry predicament is solved the most well at present.

Formula concrete structure technique code " (JGJ1-2014), but this code is without reference to the technology in terms of underground exterior-protected structure and mark
Standard, does not have directive function.Shanghai construction engineering group is attempted in prefabricated diaphram wall method, as new at Tung Wah hospital
Build the empty stomach wallboard applying ground in the Foundation Pit Support Engineering of outpatient service prefabricated and be assembled into continuous underground wall structure.Due to single width wall
Board size is relatively big (length reaches 20.5m), the most difficult in lifting and transport.
Owing to not accomplishing the assembled in situ of small members, limit this technology and do not obtain further popularization and application.
Use prefabricated tubular pile, as PHC pile tube, PRC pile tube, precast square pile and prefabricated I-shaped stake are tied as pattern foundation pit supporting structure
Structure, the most existing many units are tested, but are all limited to the application of single-unit stake, this is because the type of attachment between stake does not has
Efficiently solving, be embodied in assembled in situ connection construction difficulty, joint is unreliable, joint high in cost of production aspect, causes with using
The application in foundation pit enclosure structure of the precast reinforced concrete piles wall fabricated construction is in experimental stage.
For stress characteristic and the feature of site operation of the vertical building enclosure of foundation ditch, it is little that employing is readily transported and lifts
Size members the most quickly assembles, build a kind of not only kept off soil but also sealing go along with sb. to guard him piling wall, reduce foundation pit enclosure cost, be us
