Description
Technical field
The present invention relates to the geotechnical engineering field, relate in particular to the technology of slip casing by pressure reinforcing or jacking basis and terrace.
Background technology
Soft clay area is banketed because of large tracts of land and is caused thick sludge soil base consolidation settlement, the terrace of " the bottom of a pan " shape has brought to use and has had a strong impact on, terrace must cut and reform when serious, has not only influenced productions, cost but also high, has report to adopt in the hole method of cement injection lifting terrace of terrace, the method cement paste consumption is big, cost is high, and intensive boring also influences production, and it is influenced, also many just like the piece stone that bankets under the terrace that terrace is repaired the back quality, Grouting Pipe is squeezed into difficulty, influences the cloth hole.A kind of need not holed at terrace, adopts directional drill to yet there are no report with the method for low-cost mud mixed serum slip-casting lifting terrace.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned prior art, provides a kind of slip casting convenience, rig displacement less and the method for the directional drill slip-casting lifting terrace that cost is low.
Method according to a kind of directional drill slip-casting lifting terrace provided by the invention comprises directional drill and drilling rod, and the mixed serum that mud mixes with admixture and high-pressure injection pump and drill bit leading instrument is characterized in that comprising following construction sequence:
A, spy barrier and cleaning obstacle;
The inclined-plane bit bore of B, described directional drill, and advance described drilling rod;
C, described drill bit leading instrument are controlled the inclined-plane drill bit direction of propulsion of described directional drill, thereby regulate described drilling rod circuit, arrive the slip casting position, with described mixed serum with described high-pressure injection pump by the slip casting of fixing a point of described drilling rod;
D, repeating step C each precalculated position slip casting under terrace;
Withdraw from described drilling rod after E, the terrace lifting.
Method according to a kind of directional drill slip-casting lifting terrace provided by the invention also has following attached technical characterictic:
Be embedded with probe in the described inclined-plane drill bit, the drill-rod wire route ground drill bit leading instrument commander adjust.
The slip casting precalculated position of described step C and step D is positioned at top or the left and right side of drilling rod principal direction.
Described step D repeats at least two circulation slip castings, and the proportioning of the slurries of each slip casting is different with concentration.
Described mud is the discharging waste mud of bored pile, and described admixture is cement or flyash or lime, and described admixture consumption is the 5-20% of mud weight.
Described admixture is aggregate chips (claiming stone flour again) or sand, and the consumption of described aggregate chips or sand is the 40-70% of mud consumption.
Described admixture is the mixture of aggregate chips (claiming stone flour again) or sand and cement or flyash, and the ratio of mud, aggregate chips or sand, cement or flyash is 1:(1～2): (0.1～0.5).
Described high-pressure injection pump is fine-stone concrete pump or concrete pump, and grouting pressure is 1～20MPa.
The terrace top in described precalculated position is provided with the ballast car.
Method according to a kind of directional drill slip-casting lifting terrace provided by the invention compared with prior art has following advantage:
1, adopt directional drill in conjunction with the drill bit leading instrument, can freely change the drilling rod direction, make drill bit arrive desired location slip casting easily, construction is used building and is not produced any influence, and the rig displacement is few, and the boring cost is low.
2, can select the slip casting point as required arbitrarily, the lifting effect is easy to control.
3, adopt bored pile discharging waste mud, turn waste into wealth, significantly reduce the slurries cost, protected environment simultaneously, two get at one stroke.
4, establish the ballast car at terrace, can effectively control the diffusion radius of terrace protuberance, can reduce the slip casting number of spots.
Description of drawings
Fig. 1 is construction schematic diagram of the present invention
Fig. 2 is slip casting point layout schematic diagram of the present invention
The specific embodiment
Referring to Fig. 1, in the method for a kind of directional drill slip-casting lifting terrace provided by the invention, comprise directional drill 1 and drilling rod 2, the mixed serum that mud mixes with admixture and high-pressure injection pump 5 and drill bit leading instrument 3 is characterized in that comprising following construction sequence:
A, spy barrier and cleaning obstacle
Inclined-plane drill bit 21 borings of B, described directional drill, and advance described drilling rod 2
C, described drill bit leading instrument are controlled the inclined-plane drill bit direction of propulsion of described directional drill, thereby regulate described drilling rod circuit, arrive the slip casting position, with described mixed serum with described high-pressure injection pump 5 by the slip casting of fixing a point of described drilling rod
D, repeating step C each precalculated position slip casting under terrace
Withdraw from described drilling rod after E, the terrace lifting.
But the long distance of directional drill 1 horizontal direction is crept into, can change the drill bit direction of propulsion freely, and under the guide of drill bit leading instrument 3, make drill bit accurately arrive the predetermined degree of depth and position, therefore need not just can be in slip casting under the terrace in terrace boring, low, the easy construction of boring cost, and can not produce any influence to the normal use in ground, described mixed serum is primary raw material by mud, mix the powdery curing compound, both reduced the slurries cost, can make slurries inject soil again and harden, slip casting can divide two to three circulations to carry out, and can make lifting absolute altitude precision higher.
Referring to Fig. 1, Fig. 2, in above-described embodiment that the present invention provides, the slip casting precalculated position of described step C and step D is positioned at top or the left and right side of drilling rod 2 principal directions.Determining and can being located at optional position in the certain limit of drilling rod inceptive direction according to stage difference, purpose difference, the diffusion radius difference of slip casting of slip casting precalculated position only needs to set the drill bit running orbit and just can arrive the slip casting precalculated position.
Referring to Fig. 1, in above-described embodiment that the present invention provides, described admixture is aggregate chips (claiming stone flour again) or sand, and the consumption of described aggregate chips or sand is the 40-70% of mud consumption.Mix the thicker aggregate chips of particle or sand etc. in mixed serum, not only cost is low, and pressure dissipation is fast after the slip casting, and reply volume is little, adds an amount of curing compound such as cement, and it is fixed that mixed serum is accelerated, and reduces reply volume.
Referring to Fig. 1, in above-described embodiment that the present invention provides, described high-pressure injection pump is fine-stone concrete pump or concrete pump, and grouting pressure is 1～20MPa.Adopt fine-stone concrete pump or concrete pump, can strengthen pressure and the flow of slip casting, accelerate terrace lifting speed, relax the restriction to particle diameter in the slurries simultaneously.
Referring to Fig. 1, in above-described embodiment that the present invention provides, described step D repeats at least two circulation slip castings, and the proportioning of each slurries is different with concentration.If the ballast car is the excessive problem of protuberance amount of slip casting point during slip casting under the level ground controllably, the radius of influence of protuberance is enlarged, make protuberance milder, even, and mud adopt the discharging waste mud of bored pile, can turn waste into wealth, reduce the mud cost.
