Description
Technical field
This utility model is related to technical field of civil engineering, and specifically a kind of foundation ditch and side slope vertically go along with sb. to guard him knot
Structure.
Background technology
The piling wall type building enclosure adopted in base pit engineering or slope project is a kind of important feature shape of foundation pit enclosure
Formula, is extensively applied from all parts of the world, and current foundation ditch and side slope go along with sb. to guard him piling wall frequently with drilling (rotary digging) 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 meant in engineering site by mechanical hole building, mud off, and stake holes is formed in foundation soil, and in which
Steel reinforcement cage, in-site pouring concrete and the stake that formed are 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 the quality of concrete placed under water, and a large amount of circulation mud is produced
Slurry, the discharge of mud will cause environmental pollution with processing；Although full-sleeve construction technology can protect stablizing for hole wall, but still not
Can avoid completely carrying out the Water And Earth Pressures at balance pipe bottom using mud, due to being affected by the solid element such as hole depth, casing length, difficulty of construction
Greatly, 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, and make while having the supporting construction carried with two kinds of functions of sealing.To reduce
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,
And produce the space of certain volume, cause deform it is unfavorable to the environmental conservation for closing on.
Steel sheet pile enclosure structure, using being the Larsen steel sheet pile with occlusion, is engaged to form entirety by the fore shaft on stake side, shape
Into assembled building enclosure.But due to the restriction of its length and cross dimensions, it is only used for excavating shallower foundation ditch, such as depth is little
In the foundation pit enclosure of 6m.As its bending rigidity is less, the deformation that stress is produced is larger, in more important environmental conservation region
Should not adopt.
Soil cement is inserted into the building enclosure of pile for prestressed pipe or square pile, the double effects with gear soil and sealing.Due to
The joint connection of its prefabricated pile is difficult to wait strong ties, or joint connection construction is excessively complicated, up to the present, can only be with single
, used as foundation pit enclosure structure, single-unit stake is long maximum less than 15m, using the foundation ditch or side slope depth of the building enclosure for the prefabricated pile of section
Degree also only has 6～8m, it is clear that being received with range of application for this building enclosure is necessarily constrained.Even if the interconnection technique of joint is asked
Topic is solved, but as the cross section property of current pile tube or square pile determines that its bending resistance is limited, it is difficult to reach more rational
Supporting benefit.
Diaphram wall is the primary structure form of Construction of Deep Foundation and Extra-Deep Foundation Pit, extensively should all over the world
With.Diaphram wall is replacing many traditional deep foundations and deep footing groove enclosing structure at present, is applied to deep big foundation pit or city
In city's municipal works and railway traffic engineering.Little, noise is vibrated during construction of diaphragm wall low, it is adaptable to urban architecture compact district
Construct in domain；Wall stiffness is big, and barrier performance is good；It is applicable to various geological conditions；Can be permanently basic for superstructure；Energy
Limited ground and the space in property line is enough made full use of, returns of investment are given full play to；Work efficiency height, short time limit, reliable in quality.
Cast-in-place diaphram wall is current most popular version, but the construction ground in complex geological condition such as sandy soil stratum
Lower diaphragm wall, the slurry trench stability problem being often relatively difficult to resolve in certainly continuous wall trench underground work progress, and landslip of the sides of the trench cause
Concrete pouring quality problem, so as to 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 carries out retaining wall using mud, needs to discharge mud after casting concrete, produces
Substantial amounts of waste mud needs to process, and causes serious environmental pollution and the increase of cost.
The construction property of diaphram wall underwater casting determines that job site is difficult to ensure that the construction quality of body of wall, this
It is mass defect that cast-in-place continuous underground wall structure is difficult to improve or make up.Therefore, engineering circles are needed searching one kind badly and can be substituted
The continuous wall construction of Novel underground of cast-in-place diaphram wall, but at present this industry predicament not yet solved well.
Using precast reinforced concrete pile or wall, the stake and wall for replacing cast-in-place reinforced concrete structure will be underground engineering
The direction in field.Currently for the precast concrete of superstructure, China Inst of Architectural Standard Design works out《Assembling
Formula concrete structure technique code》, but the code is without reference to the technology and mark in terms of underground exterior-protected structure (JGJ1-2014)
Standard, not with directive function.Shanghai construction engineering group is attempted in prefabricated diaphram wall method, such as new in Tung Wah hospital
The prefabricated empty stomach wallboard in ground is applied in the Foundation Pit Support Engineering for building outpatient service and is assembled into continuous underground wall structure.Due to single width wall
Board size larger (length reaches 20.5m), it is very difficult in lifting and transport.
Assembled in situ due to not accomplishing small members, limits the technology and does not obtain further popularization and application.
Using prefabricated tubular pile, such as PHC pile tubes, PRC pile tubes, precast square pile and prefabricated I-shaped stake are tied as pattern foundation pit supporting structure
Structure, has many units at present and is tested, but be limited to the application of single-unit stake, this is because the type of attachment between stake does not have
Efficiently solve, be embodied in the aspects such as assembled in situ connection construction difficulty, joint is unreliable, joint cost height, cause with use
Application of the precast reinforced concrete piles wall fabricated construction in foundation pit enclosure structure is in experimental stage.
For the vertical building enclosure of foundation ditch stress characteristic and site operation the characteristics of, using be readily transported and lift it is little
Size members are quickly assembled at the scene, are built a kind of piling wall of going along with sb. to guard him for not only having kept off native but also sealing, are reduced foundation pit enclosure cost, be us
The direction of effort.
