Description
[technical field]
The utility model relates to one and revolves and dig occlusion steel concrete impervious wall.
[background technology]
Impervious wall be by special to dig, jet-bedding equipment, periphery along underground building presses preposition, slurry-supported excavation or drill is utilized to go out the groove of one fixed width and the degree of depth, and the cage of reinforcement with certain rigidity is set in groove, with special method joint subsection catheter perfusion underwater concrete, make it to be formed that integrally closed encloses descend reinforced concrete wall continuously, in building foundation pit, have that gear is native, the double effect etc. of bearing top-out load of percolation-proof.Drilling hole bored concrete pile technology is an important technical innovation of construction foundation working method, effectively solve the construction problem of underwater foundation, underwater operation is changed into and carries out on the water, its Technological Economy superiority is very outstanding, applied widely in the Foundation Design of the systems such as national urban construction, railway, highway, water conservancy, but it is more outstanding to seep water between stake, become wall vertical bury pipe precision not high, anti-seepage effect is undesirable; Also to have in water conservancy and hydropower project and increase curtain grouting, but construction costs is higher.
[summary of the invention]
The purpose of this utility model is to provide one can rapid construction impervious wall, solves the anti-seepage effect existed in prior art bad, the technical problems such as inefficiency, and reduces operating expenses, ensure that construction speed.
The utility model is characterised in that: comprise stake, cage of reinforcement, retainer ring, Grouting Pipe, Grouting Pipe is positioned at occlusion place; Stake adopts mud off pore-creating to be formed, and aperture is the stake of φ 800mm ~ 1000mm, occlusion distance 100mm, i.e. pile center's spacing 700 ~ 900mm, embeds rock stratum and is not less than 3 times of stake footpaths; Stake adopts Spiral digging machine porous to construct apart from jumping hole mode, subdrilling odd-numbered stake holes, the stake of tremie method underwater grouting odd-numbered, reach after 15Mpa until concrete strength and carry out even number stake (i.e. interlocking pile) construction again, cage of reinforcement is increased during this even-numbered pile driving construction, cage of reinforcement fixes the two Grouting Pipe of pre-buried φ 50mm with retainer ring, Grouting Pipe bores extravasating hole every 500mm, reach after 20Mpa until concrete strength, the cement paste that two Grouting Pipe notes admixture permeability-reducing admixture is simultaneously formed to revolve and digs occlusion steel concrete impervious wall.
The utility model comprises mud off Spiral digging machine porous apart from jumping hole pore-creating, conduit underwater concreting, interlocking pile cage of reinforcement retainer ring, pre-buried pair of grouting pipe grouting behind shaft or drift lining.First adopt Spiral digging machine to make stake holes according to design attitude mud off, stake footpath φ 800 ~ 1000mm, occlusion distance is 100mm, embeds rock stratum and is not less than 3 times of stake footpaths.Stake adopts porous to construct apart from jumping hole mode, subdrilling odd-numbered is 1., 5., 9. ... stake, bore odd-numbered more 3., 7. ... stake, tremie method underwater grouting, reach until concrete strength and after 15Mpa, to carry out even-numbered stake (i.e. interlocking pile) construction again.Cage of reinforcement is increased, interlocking pile stake footpath φ 800 ~ 1000mm, every side occlusion 100mm during interlocking pile construction, cage of reinforcement is arranged in occlusion place, and main muscle adopts φ 20 indented bars, and hoop muscle adopts φ 20 indented bars stiffening ring, spacing 1 meter, and every spacing 1 meter increases the cross hang of φ 20 indented bars.Skeleton stiffening ring coils with φ 8 annulus of circle weld diameter φ 60mm, and pre-buried φ 50mm Grouting Pipe is fixed through annulus.Grouting Pipe bores extravasating hole every 500mm, extravasating hole diameter 10mm, the cement paste noting admixture permeability-reducing admixture after 20Mpa is reached until concrete strength, be in the milk with the cement paste of water/binder ratio 0.6, each occlusal area is two-tube to be in the milk simultaneously, and grouting initial pressure 0.2 ~ 0.3mpa, terminates pressure 0.35 ~ 0.5mpa, voltage stabilizing 10min midge amount is unchanged, can terminate grouting.
Needed for Spiral digging machine pore-creating, place scope is little, and maneuverability does not limit by landform, and construction can rapid deployment.Interlocking pile increases cage of reinforcement, adds impervious wall integral rigidity, can effectively prevent leakage proof wall from ftractureing, because jumping hole mounting framework, cost-saving.Rotary drilling rig is digital control system keyhole vertical bury pipe, and can adjust correction in time according to instrument board display data at any time in boring procedure, pore-forming vertical bury pipe precision can reach within 3 ‰, can meet the technical requirements of interlocking pile occlusion thickness qualities completely; Changing interlocking pile utilizes the adjacent studs concrete initial set time difference to realize the traditional handicraft of occlusion, hard patterning method is adopted to construct, the thick hot-tempered face utilizing rotary drilling rig pore-forming formerly to pour into pile lining formation is engaged, without the need to relying on the requirement of traditional handicraft to the concrete extra retarded set time, avoid " piping " accident occurs.
In occlusion place pre-buried pair of Grouting Pipe, post jacking, ensure that the compactness of occlusion place, further enhancing impervious effect.
The utility model compared with the prior art, owing to adopting Spiral digging machine pore-creating, reduce the working strength of construction operation personnel, improve boring precision, save the engineering time, improve operating efficiency, built-in slip casting pipe slip casting improves anti-seepage effect, and the utility model can be widely used in the short bridge pile foundation cofferdam of construction period, riverine, river, lake, sea deep foundation ditch near water, the foundation pit construction that groundwater table is higher, water conservancy and hydropower material for diaphragm wall of Cofferdam is constructed.
