In order to facilitate understand the present invention above-mentioned technical proposal, below by way of in specifically used mode to the present invention it is above-mentioned
Technical solution is described in detail.
When specifically used, according to the present invention a kind of using light and dark digging, upper object exempts to remove and builds underground knot in combination
The method of structure, by taking Zhenyang occupies the building of subway station nearby as an example:As shown in Figs. 1-5:Zhenyang occupies big restaurant and is located at the stations Zhu Shikou base
The east side in hole, wire center mileage about K32+365.000 are approximately perpendicular to foundation pit side and are arranged in strip.It is two layers that Zhenyang, which occupies,
Brickwork construction, East and West direction grow 21 meters, and north and south is 6 meters wide.House stretches into subway No. 8 cities Xian Zhu mouthful station main body foundation pit 3.7 meters.Base
About 1 meter of plinth buried depth adds 50 centimetre of 28 cushion lime basis for 50 centimetres of brick walls.Materials for wall is that (after fraction plus section is common brick
Blue bricks), roofing is thin watt common, and roof truss is wooden truss, and column is log.The House Property is private house-property, builds physical property
The restaurants Zhi Wei, have been stopped using, and build up without a date, belong to dilapidated house.The range of removal is included in by government, in the Olympic Games in 2008
It can start to remove when Qianmen Dajie transformation early period, but due to various reasons, remove have no resolution always.Since station line position is true
It is fixed, wear house under inevitable.In the case where house can not remove, to ensure normal the applying of the stations Zhu Shikou open-cut foundation ditch
Work, is arranged U-shaped isolation pile in premises perimeter first, house is isolated to outside foundation pit, the structure for house not influence area of first constructing.
Then boring construction house is got off station structure again.Subway station nearby is occupied in order to by the way of light and dark digging combination, complete Zhenyang
Build, it is thus necessary to determine that following item:
1, the boundary of works area and separation of open cut and tunneling:It is to be adopted using the station whole section near corresponding Zhenyang Curie's journey section
With tunneling, part nearby only still is occupied to Zhenyang and carries out tunneling.How far isolation pile could not only protect house apart from house, but also advantageous
In implementing boring construction, operating expenses is reduced.
2, building structure analysis and the selection of construction:The emphasis of house protection needs to combine house at which position
Structure type there is emphasis protect.Tunneling vault uses which kind of tunneling engineering method vault or flat-top, tunneling use.
3, the ancillary measure of house protection:Which feasible ancillary measure to be conducive to the safety in house using.
4, the processing of light and dark digging combination node:It is the weak link of construction in conjunction with node, needs special node way.
5, the determination of the Protection parameters such as building settlement index and monitoring measurement.
Below for problem above, illustrates or discuss respectively.
1, the boundary of works area and separation of open cut and tunneling:
In the determination of light and dark digging boundary of works area, should consider in terms of open cut and tunneling two.Zhenyang is occupied in coverage
Station structure, tunneling boring implement tunneling, be conducive to the rule of open-cut foundation ditch shape, reduce due to Zhenyang occupy influence and caused by
The external corner of foundation pit, it is advantageous to the stability of foundation pit.But boring construction is costly relative to open cut increase, is cost-effective
Project dug underground amount should be reduced to the greatest extent, meanwhile, only 4.5 meters of station earthing, there is also certain technical difficulty for large area boring construction.
Therefore the quality for considering light and dark digging, should reduce the workload of tunneling to the greatest extent.
The determination of distance in isolation pile and house needs consider the following factors:The operating space of isolation pile construction machinery.Every
House foundation is reduced and is disturbed from stake and Guan Liang construction, Guan Liang bottom should as possible be located at except basic 45 ° of angles of flare.It answers the position of stake
In conjunction with station structure construction joint location determination, light and dark digging station structure seaming position as possible is reserved in simple in structure, and stress is smaller
Position.The limitation of boring construction minimum space, need to there are operating spaces appropriate to tunneling.The case where meeting conditions above
Under, the range of tunneling less as possible, and then reduce project cost and construction risk.According to conditions above, light and dark digging west side has a common boundary
The position to the east of structure armpit angle is arranged in face, and south and north flanks are arranged for 3 meters according to fender post edge apart from house foundation, is less
Guan Liang excavates the disturbance to house foundation, and Guan Liang top is put on to ground.In summary it can determine that tunneling is ranging from wide by 6.85
Rice, is about 14 meters of section.
2, building structure analysis and the selection of construction
Closing foundation ditch side Zhenyang residence is additionally arranged two attached three-legged structures by an inclined roof and forms, and therefore, give support to a roof triangle
The twice wall of truss is the main load bearing wall in house, and west side wall is located on hidden digging structure, is to be influenced maximum by tunneling
Position, therefore reinforce it is particularly important in conceptual design to the supporting of the wall.Since tunneling width reaches 7 meters or so, it is
Surface subsidence is reduced, big hole should be divided into duck eye, is excavated advantageously using CRD methods.Due to structure top earthing only 4.5 meters of left sides
The right side forms larger limitation to arch camber at the top of first branch, therefore using the first branch structure of flat-top.Supporting for reinforcement to house west side wall,
The position of CRD median septums is arranged in western headwall hereinafter, to increase support rigidity.
3, the ancillary measure of house protection
After determining tunneling excavation method, in conjunction with engineering method, supporting construction and formation condition, ancillary measure need to be taken, is further added
Strong boring construction excavates and supporting measure can ensure construction safety.Since first branch structure is flat-tope structure, to prevent ground from collapsing
It collapses, bimetallic tube canopy is set on vault.It caves in thin silt to reduce, the used time is the cohesive strength for increasing the soil body, is reduced
The east side soil body carries out supporting using deep hole grouting to first branch structure to fine sand layer after excavation.
The processing of 4 light and dark digging combination nodes
The position that light and dark digging combines is the key point that structural strength, the weak spot of waterproof and the construction of light and dark digging engineering method combine.Under
It is introduced in face of the structure connection of position of joints, waterproofing process.
The first branch of tunneling part and two linings are the structure of E fonts.Two lined steel muscle are connect by the reserved steel bar of structure built by opencut method
It refutes device with structure built by opencut method to be connected, the shear resistance of concrete is increased by reserved concrete shear slot, forms the stress of closure
System (two lining node in such as figure).To ensure the closure and force structure of just branch system, in tunneling top position, using in open cut
Structure roof reserves grid tie point to realize the closure (grids top node in such as figure) of grid.It is interim to reinforce structure built by opencut method
The intensity of system, before hidden digging structure does not complete, the position of corresponding structure built by opencut method beam column, according to 500mm (between grid etc.
Away from) it is provided with temporary support of 40 I-steel as structure.In grating base, grid and bottom fender post reinforcing bar are connected
It connects, ensures the fixation of grid end.
In water-proof system, open cut side wall uses bentonite waterproof blanket, top plate to use polyurethane coating film waterproof.Tunneling is prevented
Water layer is ECB splash guards.Waterproof should be carried out in construction from the following aspects:1) the reserved of open cut waterproof is carried out.2) tunneling is anti-
Water and the overlap joint of open cut waterproof are handled.3) the reinforcement processing of waterproof weak node.
Open cut side wall waterproof be waterproof blanket, structure built by opencut method construction finish tunneling at the beginning of branch construction complete, start waterproof and
Two lining constructions, elapsed-time standards is longer, is easily invaded by outside moisture, damp failure, therefore reserved overlap joint trouble is anti-using plastics etc.
Water material will protect after reserved waterproof blanket winding up.Pass through the external disturbances such as broken pile and first branch excavation during waterproof exposes,
Iron sheet or other hard materials should be used to be protected.Before the lining construction of tunneling two, it is laid with tunneling waterproof layer, should be carried out at this time swollen
The overlap joint of profit native waterproof blanket and ECB splash guards.The lap of splice is not less than 20cm.Using bentonite crimp ECB splash guards, the two it
Between pasted with bentonite fluid sealant.
It is difficult to reserve overlap joint for polyurethane coating film destructible at top.It therefore should be in advance by the poly- of ECB splash guards and top
Urethane film is overlapped in open cut part, and ECB splash guards are reserved to tunneling and are overlapped.
Even if using the above treatment measures, the weak spot that batch position is still waterproof is connect.Therefore it should be used in structure
Two pass water-swellable water-stop glue carries out joint strengthening.Built-in slip casting pipe is answered in construction simultaneously, and Ying Shui is used after the completion of construction
Mud carries out grouting reinforcing to structure.
The determination of the Protection parameters such as building settlement index
The general of the sedimentation index in house determines according to the assessment result of professional house appraisal agency.But due to the House Property etc.
The reason of aspect, the assessment fail smoothly to carry out.Therefore determine that sedimentation index is answered under conditions of lacking necessary assessed information
Integrated structure feature, the attainable standard of construction technology determine sedimentation index jointly.Meanwhile tour of the reinforcement to house in construction
And monitoring.If any special circumstances, necessary adjustment is carried out to index in time.
House roof truss span reaches 13 meters, and the relative settlement of concern house load bearing wall is the major control point of monitoring.
Sedimentation index digs stage sedimentation and tunneling just branch stage sedimentation clearly, the first branch of tunneling is removed and two lining stages sedimentation three phases.
Branch stage at the beginning of construction process control divides open-cut foundation ditch stage, tunneling according to the sequencing of construction and first branch remove and
Two lining stage three parts.It is introduced separately below:
1 open-cut controls
Structure built by opencut method construct emphasis from go along with sb. to guard him pile driving construction, Guan Liang construction, foundation pit excavation and bracing, structure construction and supporting removal,
The processes such as backfilling of earthwork are controlled.Meanwhile it should be carried out in open-cut and hidden digging structure connecting portion is reserved.
Going along with sb. to guard him pile driving construction uses rotary drilling rig, the stage emphasis to carry out the quality control of mud off, prevent collapse hole
Phenomena such as, influence the stabilization of house foundation.After the completion of going along with sb. to guard him pile driving construction, excavation performs Guan Liang.The support of Guan Liang layer uses coagulation
Soil support.Concrete support can bidirectional stress.Be conducive to foundation pit external corner Deformation control.The support at other positions, when implementation, first apply
The straight support in work face house, after construction to be supported, then performs corner buttresses.To ensure corner buttresses along external corner direction
Power can be undertaken by straight support, prevent the outside deformation of external corner.Meanwhile when diagonal brace is constructed, the shearing resistance of purlin behind is pedaled and must be applied
Do it is solid reliable, to ensure the transmission of diagonal brace axle power.
Before excavation of foundation pit, grouting and reinforcing is carried out in premises perimeter setting mini-valve tube, in Excavation Process, according to room
The monitoring situation in room carries out benefit slurry in time using mini-valve tube to premises perimeter, is the important hand of open cut stage building settlement control
Section.
During excavation of foundation pit, the coordination of excavation and support should be carried out, is ensured with digging with support.It constructs in structure built by opencut method
In the process, it also should gradually be removed with structure construction, the moment ensures the stress balance of foundation pit supporting system.Structure built by opencut method construction finishes
Afterwards, it should be layered rammed earth, tunneling broken pile construction can be carried out after being backfilled to ground, to ensure the backfill earthwork to the above stake of top plate
Restricted back-pressure effect.
2 preliminary bracing Construction controls
Include advance support construction, partial excavation two key links of construction in first branch construction overall process.Wherein in partial excavation
Abolishing for isolation pile influences maximum to building settlement.It excavates and is excavated using 8 pilot tunnels of CRD methods point.Sequence of excavation presses icon
Number carry out.Detailed process is as follows:
Pipe canopy is performed first before excavating, and the top soil body is formed with the double-deck long pipe shed and is supported.Pipe canopy applies alloy water drilling before performing
The trepanning in stake, and stake cannot be directly cut off, ensure that stake occupies Zhenyang the effect of going along with sb. to guard him of the periphery soil body.Pipe canopy is drilled to using spiral
Hole can generate the soil body certain crowd in-out effects, reduce the sedimentation in house.The drilling equipment using high pressure geomantic omen class should be avoided,
To reduce the loss of the soil body.Pipe roof construction should jump hole and perform, and perform and be spaced in 5 holes or more.After single hole pore-forming, down tube is noted immediately
Slurry filling, cannot wait for that porous pore-forming unifies slip casting, to ensure the promptness of filling.
Excavation construction, first perform Zhenyang occupy lower part 1., 2. number hole, then construct 3., 4. number hole.3., 4., 7., 8. number
During pilot tunnel is implemented, it is completed at the same time abolishing for row's open cut fender post.Wherein 3. the cut-out of number hole stake generates whole stress system
Influence it is maximum, meanwhile, the point of broken pile is nearest apart from house foundation, and disturbance is maximum.Static(al) measure should be used as possible, reduce shake
It is dynamic, to the sedimentation in less house.
Before the 3. cut-out of number pilot tunnel stake, the pre-buried reinforcing bar connector more than open cut top plate.It is former after fender post is abolished
Open cut reserves connector and is disclosed for out.Spreading reinforcing bar is connected in connector, then is connect with grid with reinforcing bar.
First branch is removed and two lining Construction controls
First branch removes the completion for being related to final structure system with two lining constructions, and during system transform, interim branch is removed by branch
Support gradually replaces interim just branch structure with permanent lining, secondary lining.Dismounting few as possible, the method being supported in time are followed in construction.
Branch structure at the beginning of 14.7 meters of direction being excavated abolishes point three sections of progress.Two lining structures of intermediate bin are first performed, the segment structure is 5 meters wide,
80~100cm waterproofs and structure are reserved per side get rid of stubble and be also required to the same period abolish.Both sides retain about 4m per side and just prop up.Two linings are using full
Hall holder full framing and newly pours structure collective effect, forms new hold before two lining concrete structures are not up to design strength
Power structure.
According to above step, when intermediate bin is constructed, structure base slab is performed, only the part for influencing bottom plate is abolished.
The time is abolished in this way, on the one hand reducing, it is ensured that bottom plate performs in time, meanwhile, top does not abolish first branch structure and both sides
The space concrete slab girder construction that concrete structure is formed, still has supporting role to top.Similarly, second step is abolished also only broken
Except structure construction position is influenced, reduces just branch and remove to integrally-built decrease, guarantee construction safety can be played, protect house
Effect.Just branch dismounting is walked in intermediate bin third to finish, and after the completion of structure construction, effective supporter is formd to house lower part
System.After the completion of 5 meters of intermediate bin width, in addition just branch structure and pipe booth structure are to the expansion effect of lower support power on top,
More effective supporting is formd to house foundation position.
In conclusion the more full cut and cover method of the present invention reduces removal, guarantee project progress, while housing demolition expense up to hundred million
