Abstract
The present invention provides concrete pile constructing process. Inside prestressed pipe pile, stuffing is extruded and concrete is deposited to form effective composite carrier while ensuring the quality in the pile end combining part and raising pile quality. The construction process includes the following steps: selecting proper soil as the pile end bearing layer; depositing the prestressed pipe pile to designed depth with driving apparatus; filling the hole of the pipe pile with stuffing and tamping repeatedly to form the optimal extruded earth body; filling the bottom of the pipe pile with low flowability concrete in certain amount and expanding the pile hole; depositing reinforcing bar cage inside the pile pipe; depositing concrete inside the pile pipe and pounding to densify.
Description
Technical field
The present invention relates to field of civil engineering, particularly relate to the construction technology of stake.
Background technology
In patent No. ZL98101041.5 patent documentation, a kind of construction technology of concrete pile is disclosed---the complex carrier compaction pile, this stake comprises complex carrier and concrete pile body, the characteristics of this technology are the variation of stake itself not to be studied, but pay attention to the maximum optimum reinforcing of the soil body under the stake end compacted, and hit the pile penetration standard by three and form complex carrier effectively, allow upper load effectively by stake and the following complex carrier of stake, be delivered on the better bearing stratum, thereby improved the bearing capacity of stake greatly, therefore had the bearing capacity of single pile height, advantages such as cost economic.But this job practices finds that in quality examination the settling amount of stake is excessive sometimes, and complex carrier also reaches the degree of destruction far away, its reason is that the quality of pile body and stake end joint portion is prone to problem, particularly in the higher soil layer of mucky soil or water content, construct, though taked measures such as cylinder-wall protecting, in the process of concrete perfusion and proposition casing, mud or water easily enter the joint portion of pile body and complex carrier, influence stake end joint portion quality causes the settling amount of stake excessive.
Summary of the invention
The present invention proposes in order to solve the above problems, purpose is to provide a kind of job practices of concrete pile, pile body adopts pile for prestressed pipe, in the mesopore of pile tube, directly carry out operations such as filler is compacted, concrete perfusion, when effectively forming complex carrier, can positively guarantee stake end joint portion quality, improve the qualification rate of stake, reduce the settling amount of stake.
To achieve these goals, the job practices of concrete pile of the present invention comprises the steps:
1), select better foundation soil as bearing course at pile end according to geology prospecting report and building upper load;
2) place, predetermined stake position in ground is sink to the design elevation place by power set with pile for prestressed pipe;
3) mesopore by above-mentioned pile for prestressed pipe, insert prose style free from parallelism inserts to stake pipe bottom on one side, pass through hammer ram on one side, the above-mentioned prose style free from parallelism inserts of inserting is tamped, carry out this filling and compacting operation repeatedly, to above-mentioned stake pipe bottom, promptly the certain depth of stake end below and the foundation soil body of scope carry out closely knit reinforcing, satisfy the compacted soil body of the optimum of necessary requirement until formation;
4) mesopore by above-mentioned pile for prestressed pipe is filled the low flow regime concrete of scheduled volume to stake pipe bottom, and by above-mentioned hammer ram, with little energy, low distance goes out stake pipe bottom with above-mentioned low flow regime concrete is squeezed gently;
5) mesopore by above-mentioned pile for prestressed pipe, descending reinforcing cage in the stake pipe;
6) by the mesopore of above-mentioned pile for prestressed pipe, concrete perfusion in the stake pipe carries out vibration compacting to concrete, finishes the pile body construction.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 1) in better foundation soil be meant the intensity and the deformation requirements that can satisfy upper load, can reinforce compacted soil layer simultaneously.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 2) mode that sinks to of pile for prestressed pipe is that mode by static pressure, hammering and vibration realizes in.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 2) in the bottom of pile for prestressed pipe precast pile tip is set in.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 3) the compacted soil body that satisfies the optimum of necessary requirement in is meant and meets following condition a), ground does not swell simultaneously, when the established compacted soil body of adjacent studs not being impacted, form by the prose style free from parallelism inserts of tamping the compacted soil body and the complex carrier that influences soil body formation at the stake end, obtain the maximum diffusion area Ae of stake end thus, to obtain maximum supporting capacity; The final filling compacting degree that this condition a) refers to above-mentioned inserts is hit total injection amount control by three, promptly under situation about not feeding intake, so that predetermined hammer is heavy, distance falls, the empty continuously three injection amounts of hitting of making a call to of test hammer ram, wherein previous injection amount greater than after once injection amount, promptly second hit the empty injection amount of beating and hit sky less than first and beat the injection amount, the 3rd hits the empty injection amount of beating hits less than second and emptyly beats the injection amount or to beat the injection amount fair with second sky that hits, and above-mentioned three hit total injection amount should be less than three design loads of hitting the injection amount.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 3) carries out this filling repeatedly in and the compacting operation is what to carry out in the mesopore of pile for prestressed pipe.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 3) prose style free from parallelism inserts refers to mashed watt of brickbat, harsh concrete, concrete block, various discarded aggregates, cobble, slag etc., or the compound of mentioned component in.
The characteristics and the advantage of the concrete pile that forms by above method are:
1. pile quality is reliable.Owing to adopted pile for prestressed pipe to make pile body, in pile body, establish reinforcing cage and concrete perfusion again, its pile quality improves greatly than general cast-in-situ concrete pile body.
2. stake end joint portion quality improves.Owing in the mesopore of pile for prestressed pipe, directly carry out operations such as filler rammer-enlarged compaction and descending reinforcing cage, perfusion pile concrete, avoided mud or water to enter the possibility of the joint portion of pile body and complex carrier, improve stake end joint portion quality greatly, upper load more effectively is directly delivered to complex carrier, significantly reduces the settling amount of stake.
3. Zhuan bearing capacity height.Stake such as general relatively pile for prestressed pipe, tube-sinking cast-in-situ pile, static pressed pile shape, owing to form effective complex carrier at the stake end, significantly improve the bearing capacity of stake, stake end complex carrier can be located at soil layer relatively preferably such as silty clay, silt, sand simultaneously, therefore can shorten the length of stake.
