Description
Technical field
The present invention relates to the constructions of municipal works deep footing groove enclosing structure, more particularly, to the nothing for going along with sb. to guard him pile driving construction suitable for subway
Lead wall construction method of interlocking pile.
Background technique
Municipal works deep footing groove enclosing structure is relatively common using interlocking pile form, belongs to common type, and interlocking pile is normal
Construction method is that first wall is led in construction, then using full-sleeve follow-up construction.This method is good suitable for site condition, and pipeline moves
Change thorough region.But for the municipal works such as subway, site condition generally than narrow, pipeline change move it is universal not thorough
Bottom carries out full-sleeve follow-up construction interlocking pile after leading wall using first construction in this case, and difficulty is larger.On the one hand, traffic
It leads and changes the more dispersed of construction site division, can not continuously construct and lead wall, construction equipment transition number is caused to increase, turn
Field difficulty is big；On the other hand, as shown in Fig. 2, when using there is construction of guide wall interlocking pile, it is necessary in tip position, sand pile 1.1 is set,
And cold seam 1.3 is easy to appear at the faying face of sand pile 1.1 and plain concrete pile 1.2, this adds increased later period infiltration hidden danger；Third
Aspect leads wall using first construction and carries out occlusion pile driving construction again, and the evacuation and protection to underground utilities (optical cable, cable) are not flexible.
Summary of the invention
It is an object of that present invention to provide a kind of nothings for going along with sb. to guard him pile driving construction suitable for subway to lead wall construction method of interlocking pile, and realization has
Effect makes every effort to promote occlusion to the occlusion pile driving construction in city limited space operating condition, underground utilities complicated condition
Pile driving construction efficiency and quality reduce construction cost.
To achieve the above object, the present invention takes following technical proposals:
The nothing of the present invention for going along with sb. to guard him pile driving construction suitable for subway leads wall construction method of interlocking pile, includes the following steps:
Step 1, after the completion of trial trench excavates, multiple casings are disposably continuously buried according to the plain concrete pile piling foundation plan paper of design,
It encounters when can not temporarily move the underground utilities changed, using the surplus of the pipeline by pipeline temporarily around two adjacent casings
Between clearance position；
Step 2, it constructs in each casing buried respectively plain concrete pile；
Step 3, after the concrete strength of the plain concrete pile reaches 3.5KPa, casing is extracted, with two neighboring plain coagulation
The line of centres midpoint of native stake is the center of circle, the meat or fish concrete stake holes of design diameter is drilled out using drilling machine, while in two neighboring element
Occlusal surface is formed on concrete-pile；
Step 4, hang steel reinforcement cage in the meat or fish concrete stake holes, by design requirement concrete perfusion, formed with it is two neighboring
The meat or fish concrete-pile that plain concrete pile is mutually engaged.
Strength grade of concrete used in the plain concrete pile is common C15 concrete.
The invention has the advantages that major embodiment is in the following areas:
1, the present invention uses embedded casing bored pile that setting is replaced continuously to lead wall progress without wall occlusion pile driving construction is led, by place item
Part limitation is small.
2, lead wall occlusion pile driving construction using present invention nothing without ultra-retardation concrete is only with common C15 concrete
Can, therefore while constructing, can relax the occlusion time limit, and occlusion pile driving construction is influenced smaller by time and space switching, and can save extra retarded set
Concrete construction cost about 15%.
3, when having construction of guide wall interlocking pile using tradition, leading wall specification needs to fix, when meeting end wall position occlusion pile driving construction,
Stake diameter will appear variation, therefore leads wall specification and also need to adjust, customize.The present invention uses cut method skills in drilling occlusive pile construction, only
Casing diameter need to be adjusted, switches casing diameter at any time, meets various diameter interlocking pile combinations.
4, tradition leads wall occlusion pile driving construction and needs that sand pile is arranged in end, when using section construction and two sections of constructions
Between when being spaced longer, soft cutting method construction is easy to generate cold seam on new-old concrete interface, and there are percolating water hidden danger.The present invention
It is cut method drilling construction without wall occlusion pile driving construction is led, i.e., cut is carried out to the plain concrete pile of construction early period and cut, cut surface etc.
It is same as having carried out a dabbing processing, new-old concrete interface is capable of forming effective occlusion, avoids new-old concrete interface
Cold seam is formed, water-stagnating effect is improved.
Detailed description of the invention
Fig. 1 is the interlocking pile planar structure schematic diagram of the invention without construction of guide wall.
Fig. 2 is the interlocking pile planar structure schematic diagram that tradition has construction of guide wall.
Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, the nothing of the present invention for going along with sb. to guard him pile driving construction suitable for subway leads wall construction method of interlocking pile, including following
Step:
Step 1, it is disposable according to the plain concrete pile piling foundation plan paper of design after the completion of subway goes along with sb. to guard him the excavation of the trial trench in pile driving construction
Multiple casings are continuously buried, are encountered when can not temporarily move the underground utilities changed, using the surplus of pipeline by pipeline temporarily around two
Then clearance position between a adjacent casing carries out the backfill of casing periphery；
Step 2, it constructs in each casing buried respectively plain concrete pile 1, strong concrete used in plain concrete pile 1
Degree grade is common C15 concrete；
Step 3, after the concrete strength of plain concrete pile 1 reaches 3.5KPa, casing is extracted, with two neighboring plain concrete pile
1 line of centres midpoint is the center of circle, the meat or fish concrete stake holes of design diameter is drilled out using rotary drilling rig, while rotary drilling rig is in phase
Cutting forms occlusal surface 2 on adjacent two plain concrete piles 1；
Step 4, steel reinforcement cage is hung in meat or fish concrete stake holes, by design requirement concrete perfusion, is formed mixed with two neighboring element
The meat or fish concrete-pile 3 of solidifying soil 1 phase of stake occlusion.
