Abstract

The invention discloses a kind of bored pile construction method passing through existing Large Underground space structure, use following steps: one) earthing on existing underground structure top board is excavated in bored pile construction region, and abolish top board and the base plate of existing underground structure;Two) inside existing structure, perform armored concrete block wall and lead wall base plate;Three) reach after design requires, to perform and lead wall sidewall, formed by the rectangle hole leading wall and block wall surrounds wait leading wall base plate strength;Four) backfill rendzinas in rectangle hole interior laminate layer and tamp;Five) use churning driven pore-forming, perform cast-in-situ bored pile.The pressure in wall and block wall carrying construction from all directions is led in present invention utilization, and stability is strong, and safety coefficient is high;Speed of application is fast, and efficiency is high;Lead wall and block wall construction cost be low, labor and materials saving, and can AT STATION excavation of foundation pit time together abolish recovery with existing structure in foundation ditch, it is possible to save resource, promote the recycling of resource.

Description

Pass through the bored pile construction method of existing Large Underground space structure
Technical field
The present invention relates to the construction method of a kind of cast-in-situ bored pile, particularly relate to one and pass through existing Large Underground space The bored pile construction method of structure.
Background technology
Along with developing rapidly of urban construction, plot ratio increases increasingly, for protection urban ground environment, alleviates urban ground Traffic pressure, Urban Underground Space Excavation rises therewith.After entering 21st century, China starts to plan energetically, develop underground Space, subway construction is especially pronounced.Can be affected by the existing underground space unavoidably when subway is built in urban center territory, that It is accomplished by passing through the existing underground space when constructing station fender post.The existing boring passing through existing Large Underground space structure The construction method of bored concrete pile is: one) when going along with sb. to guard him drilled pile and passing through existing structure, and rotary drilling rig uses rotation to dig pick alloy bit Carry out creeping into passing through.Two) it is drilled into 1m under existing structure base plate, uses whole steel pile casting to carry out retaining wall installation place whole cavity section Reason.Three) use bucket tooth churning driven head to replace pick tubular alloy bit after passing through existing structure and carry out creeping into of soil layer section Construction, finally creeps into absolute altitude hole at end at the bottom of design stake.Existing construction method there is problems in that one) use steel pile casting retaining wall, after Phase can not recycle and reuse, and construction cost is high, causes waste of material.Two) pick bores construction efficiency slowly, and the construction period is long.
Summary of the invention
The present invention solves that technical problem present in known technology provides one to pass through existing Large Underground space knot The bored pile construction method of structure, the method construction cost is low, and efficiency of construction is high.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: one pass through existing greatly The bored pile construction method of type underground space structure, employing following steps :) both excavate in bored pile construction region There is the earthing on underground structure top board, and abolish top board and the base plate of existing underground structure;Two) inside existing structure, steel is performed Reinforced concrete block wall and lead wall base plate, leads wall base plate and performs on the top board of existing underground structure and be positioned at block wall top; Three) reach after design requires, to perform and lead wall sidewall, formed by the rectangular opening leading wall and block wall surrounds wait leading wall base plate strength Hole;Four) backfill rendzinas in rectangle hole interior laminate layer and tamp;Five) use churning driven pore-forming, perform cast-in-situ bored pile.
In construction procedure one) the most first divide construction flowing water section.
The present invention has the advantage that with good effect: utilizes and leads in wall and block wall carrying construction from all directions Pressure, stability is strong, and safety coefficient is high;Speed of application is fast, and efficiency is high;Lead wall and block wall construction cost is low, labor and materials saving, and And can AT STATION excavation of foundation pit time together abolish recovery with existing structure in foundation ditch, it is possible to save resource, promote resource circulation Utilize.

In figure: 1, lead wall sidewall, 2, top board, 3, lead wall base plate, 4, block wall, 5, base plate, 6, rendzinas, 7, earthing.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing Describe in detail as follows:
Refer to Fig. 1~Fig. 2, a kind of bored pile construction method passing through existing Large Underground space structure, use Following steps:
One) excavate the earthing 7 on existing underground structure top board in bored pile construction region, and abolish existing underground knot The top board 2 of structure and base plate 5.
Two) inside existing structure, perform armored concrete block wall 4 and lead wall base plate 3, leading wall base plate 3 and perform existing On the top board 2 of underground structure and be positioned at block wall 4 top.
Three) after leading wall base plate 3 intensity and reaching design requirement, perform and lead wall sidewall 1, lead end face and the ground of wall sidewall 1 Concordant, formed by the rectangle hole leading wall and block wall 4 surrounds.
Four) backfill rendzinas 6 in rectangle hole interior laminate layer and tamp.
Five) use churning driven pore-forming, perform cast-in-situ bored pile.
Above-mentioned cast-in-situ bored pile is typically the fender post of foundation pit structure.
When existing underground structure size is relatively big, and the cast-in-situ bored pile of needs construction is more, generally in construction procedure one) it Front first divide construction flowing water section, by the construction of construction flowing water section tissue cast-in-situ bored pile, with convenient construction tissue, quickening construct into Degree, reduces construction cost.
Although the preferred embodiments of the present invention being described above in conjunction with accompanying drawing, but the invention is not limited in The detailed description of the invention stated, above-mentioned detailed description of the invention is only schematically, is not restrictive, this area common Technical staff is under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, also Can be to make a lot of form, within these belong to protection scope of the present invention.

Claims (2)

1. the bored pile construction method passing through existing Large Underground space structure, it is characterised in that use following step Rapid:
