Abstract
This is a concrete grouting method and the facility. The method is as: drill to the designed depth and fill in concrete through the drill and raise the drill simultaneously till designed level. Select grouting pipe according to the grouting manner from side wall or from the top end or together. In case of side wall grouting, the grouting pipe is directly fixed to the reinforcing cage and put into the drill hole together. In case of top end grouting, the grouting pipe is drilled through the concrete into the soil. Grouting time is 1-4 weeks after pile accomplished.
Description
Technical field:
The present invention relates to the job practices and the construction equipment of a kind of drilling tool center pumping concrete stake side pile bottom post grouting concrete filling pile.
Background technology:
The stake side of extensive use at present, the pile bottom post grouting concrete filling pile is all realized under dried operation pore-forming or mud off pore-forming technique, though it has solved end load and the side frictional resistance problem that improves stake.But once finish promptly " bore and irritate unification " owing to can not realize boring and concrete pouring in the work progress.So its complex process, speed of application is slow, contaminated environment, quality control difficulty.And the various spiral drills center pumping concrete filling pile of using in recent years, as CFG stake, superfluidity stake etc., because its technology particularity, its stake end and side frictional resistance are all lower.In order to solve the problems referred to above of spiral drill center pumping concrete filling pile, many knowledgeable people have dropped into a large amount of financial resources energy, research and develop, as penetrate slurry expanded bore pile, rotary-jetting bottom-expanding pile, expand end agitation pile etc., all because its device structure is too complicated, technology is restive, so use lessly, and existing some device exists 1, the slip casting tube apparatus is too complicated huge down, following slip casting pipe unit poor reliability, Grouting Pipe is difficult for breaking away from the shake tube pulling; 2, the shake pulling device vibrates in the hole of concrete is arranged, and very easily concrete is caused from rare, and gravel sinks to the stake bottom, shakes tube pulling like this and can not reach the stake bottom, so Grouting Pipe can not arrive the stake bottom; Though 3, a small amount of rubble is arranged at the Grouting Pipe bottom, but at the bottom of no matter whether Grouting Pipe arrives, the Grouting Pipe outside is to be wrapped up by concrete, when reaching 30%～100%, easily cause concrete strength Grouting Pipe to block, hole-bottom slurry-injection such as can not realize at shortcoming, also exist in the prior art in addition a kind of to behind the pump-injecting concrete pile of auger stem center to a kind of remedial measure at the bottom of the stake, it is lowered to the Grouting Pipe degree of depth certain limit, slip casting is slip casting immediately when pile, so be not grouting behind shaft or drift lining worker method, its slip casting effect does not far reach the grouting behind shaft or drift lining method.
Summary of the invention:
The purpose of this invention is to provide a kind of drilling tool center pumping concrete filling pile that can reach and have the afterwards job practices and the construction equipment thereof of the drilling tool center pumping concrete post mudjack concrete pouring pile of pouring mortar pile concurrently.
Above-mentioned purpose realizes by following technical scheme:
The job practices of a kind of drilling tool center pumping concrete post mudjack concrete pouring pile is at first bored the stake hole to prescribed depth with drilling tool; By pumping concrete material in the mind-set hole in the drilling tool, promote drilling tool simultaneously then, and guarantee the concrete face all the time on the discharging opening of drill bit, pumping concrete material to specified altitude, the proposition drilling tool; Choose a sidewall slip casting or pile end grouting or the slip casting simultaneously of stake sidewall stake end; According to selected grouting mode Grouting Pipe is installed; The sidewall Grouting Pipe can be directly installed on the reinforcing cage, together be lowered in the hole with reinforcing cage, the pile end grouting pipe by rig or manually drive pile end grouting Guan Zaiyi perfusion finish pierce in the stake hole of concrete at the bottom of below original soil layer in, stake side and carrying out in 1～4 week behind pile pile end grouting time.
The job practices of above-mentioned drilling tool center pumping concrete post mudjack concrete pouring pile, described concrete filling pile are helical burr ram or reaming stake or straight hole pile.
The pile end grouting pipe of the construction of a kind of drilling tool center pumping concrete post mudjack concrete pouring pile, its composition comprises: drill bit, Grouting Pipe has the grout outlet that links to each other with described Grouting Pipe on the described drill bit.
The pile end grouting pipe of the construction of above-mentioned drilling tool center pumping concrete post mudjack concrete pouring pile, described Grouting Pipe are full helical blade or part helical blade.
This technical scheme has following beneficial effect:
1. the inventive method collects spiral drill center pumping concrete, and the advantage of mud jacking can greatly improve bearing capacity of single pile after the reaming, and maximum can improve pile capacity more than 2 times.
2. the inventive method has solved the big defective of heavy quarrel at the bottom of the injecting concrete stake stake of drilling tool center, further improves a stake side frictional resistance, and the problem of bearing capacity of pile tip makes advantage of this type of and back pouring mortar pile all obtain giving full play to.
3. the inventive method can be selected only stake side slip casting, pile end grouting and the slip casting simultaneously of stake side stake end for use according to the bearing capacity difference of stake, and stake side slip casting is because Grouting Pipe is together to descend in the hand-hole with reinforcing cage, so the simple speed of constructing is fast.Pile end grouting is also reinforced stake end loosened soil when reinforcing stake end primitive soil, so stake side slip casting effect is good for its pile capacity.The slip casting simultaneously of stake end stake side can improve the bearing capacity of stake greatly, and maximum can improve bearing capacity of single pile more than 1.5 to 2 times.
4. pile end grouting pipe construction device of the present invention, but the steel pipe merogenesis be lowered in the hole, the thickness of steel pipe diameter can reduce, cost reduces equally, in the following original soil layer, can guarantee that grouting port is not blocked by concrete at the bottom of Grouting Pipe is lowered to, Grouting Pipe is unimpeded, because Grouting Pipe is provided with drill bit, can select helical blade as required for use again, following Grouting Pipe speed is fast, simple to operate, it is fast to pierce Grouting Pipe speed with rig, and the degree of depth is reliable.
5. by rig or manually drive pile end grouting pipe rotation and pierce, in the following original soil layer, can hold primitive soil to reinforce at the bottom of reaching to stake always.
6. use the inventive method can realize " bore and irritate unification ", has the characteristics that back pouring mortar pile bearing capacity increases substantially again, the inventive method construction equipment mature and reliable and simple.
