Claims (7)
- A kind of 1. Bridge Pile Foundation Construction method, it is characterised in that comprise the following steps:S1:Surveying and locating:Pile foundation construction setting-out is carried out using total powerstation, actual survey is carried out to construction ground, gathers construction ground Soil, carries out experimental analysis, determines the content of soil, according to the hardness of different depth soil, determines depth and the position of pile foundation, Whole work progress is first simulated according to the data of actual survey and experimental data on computers, draws preset value;S2:Levelling of the land:Smooth, the debris progress on the construction site needed after smooth is carried out to place using construction machinery Cleaning, using fill out weak soil and pound it is closely knit be used as drilling machine construction platform, by drilling-machine shifter to construction platform, then to drilling machine bottom Seat carries out support pad and reinforcing;S3:Borehole:Stake holes is dug out using the drilling machine described in S2, perforate generally puts into large scale clay, makes underflow, using small punching The urgent head for hitting pore-creating, wanting in close observation casing in drilling process in Cheng Jinhang bottoms, keeps being higher by 1.5-2m than working water level, And send special messenger to check geologic change situation and mud index, the mud of different indexs is adjusted according to different geological states, when logical When crossing erratic boulder layer, such as surface irregularity, should first launch clay or small slabstone levels up surface, then percussion drilling, prevent tiltedly Hole, collapse hole phenomenon, stake holes are completed aperture after depth, Kong Wei, aperture and gradient and are detected, and draw detection data, and with S1 The construction simulation process is contrasted, if correction data is in the error range of permission, you can continues to construct, if by mistake , it is necessary to adjust in time if difference is larger, continue to be contrasted with analogue data after the completion of adjustment, until meeting preset value;S4:Steel reinforcement cage enters hole:After the completion of stake holes described in S3, by reinforcing bar cage hoisting into stake holes, due to steel reinforcement cage diameter ratio It is larger, using triangle support is welded with putting more energy into and bind round in steel reinforcement cage, four pieces of concretes protection cushion blocks are symmetrical arranged every 2m on steel reinforcement cage, Steel reinforcement cage is reinforced;S5:Borehole cleaning:The mud property index and stake holes bottom sediment thickness of stake holes bottom described in S3 are detected, draws testing number According to being contrasted with the analogue data described in S1, meet preset value and can proceed with construction, if numerical bias is larger Words, it is necessary to handle it in time, until reaching preset value, borehole cleaning using changing slurry processes progress, with it is having purified, relative density is relatively low Mud press-in, the larger mud of relative density and suspension boring mud are swapped out outside hole, liquid level stabilizing in retaining hole, until mud in hole Untill the indices and sediment thickness of slurry meet specification and design requirement;S6:Concrete perfusion:The perfusion of concrete is carried out using direct pipe method, in casting process, conduit planted agent often fills up Concrete, and keep conduit base opening to be embedded in all the time in the concrete poured, simultaneously balancedly casting concrete, is simultaneously slowly lifted Conduit, until terminating, during using tremie method, the maximum particle diameter of aggregate will be restricted, and concrete batching system need to have good Workability and the higher slump, first detection concrete enters the indexs such as hole temperature, air content, the slump before perfusion, draws data And contrasted with the preset value described in S1, timely processing is needed if error is larger, after the completion of processing again with preset value into Row contrast, can carry out the perfusion of concrete after meeting the requirements.
- A kind of 2. Bridge Pile Foundation Construction method according to claim 1, it is characterised in that in the S1, construction lofting point Position precision is less than 4mm, and setting-out result is protected after the completion of setting-out.
- 3. a kind of Bridge Pile Foundation Construction method according to claim 1, it is characterised in that in the S1, examined using soil Available nitrogen, rapid available phosphorus in survey instrument detection soil, effective potassium, the full nitrogen in plant, full phosphorus, full potassium, the content of organic matter, soil acid The component such as basicity and soil salt content draws accurate data.
- 4. a kind of Bridge Pile Foundation Construction method according to claim 1, it is characterised in that in the S3, hole depth is not less than Default hole depth, aperture are not less than default aperture, and gradient tolerance is less than 1%.
- 5. a kind of Bridge Pile Foundation Construction method according to claim 1, it is characterised in that in the S4, used by crane 2 points of liftings, the first suspension centre are arranged on the lower part of skeleton, and the second suspension centre is arranged on the center of skeleton.
- 6. a kind of Bridge Pile Foundation Construction method according to claim 1, it is characterised in that in the S5, stake holes bottom sinks Slag thickness should be less than 280mm.
- 7. a kind of Bridge Pile Foundation Construction method according to claim 1, it is characterised in that in the S6, concrete is by thin Gather materials, coarse aggregate and composite reinforcing fiber mixing 5-7min, then add cement, coal ash powder, miberal powder and silica flour stirring 5- 7min, is eventually adding water, polycarboxylate water-reducer, dispersant and organic silicone oil stirring 5-7min, that is, concrete is prepared.
