Abstract
The utility model relates to a pile tool for driving piles for the foundation construction of buildings. The utility model has the essential technical proposal that the lower end of a pile pipe is fixedly provided with a sleeve, and the upper end of the pile pipe is fixedly provided with a pair of pipe drawing ear plates; a bulldozing piston is installed in the sleeve, and the upper end of the bulldozing piston is fixedly provided with a cross beam which passes through a groove on the pile pipe to extend out of the pile pipe. The utility model integrates the advantages of a soil squeezing pile and a soil discharging pile into integration and can penetrate complicated stratums containing pebble layers, erratic stone, etc. The utility model has the advantages of regular hole-forming shape and smooth hole wall and can enhance hole drilling efficiency.
Description
The utility model relates to the used stake tool of a kind of building lot construction piling.
At present, the construction work pile foundation can be divided into two classes substantially, one class is the soil compaction stake, as precast reinforced concrete piles, another kind of is displacement pile, as the stake of wet method holing with slurry wall protection, dry method augered piles etc. for general ground, are feasible with above stake type, but, hard for soil property, particularly contain layer of gravel, the ground that erratic boulder etc. are complicated is if adopt precast reinforced concrete piles, Chang Yin runs into rubble in the construction, and squeeze into difficulty, and often smash stake top easily or pile body is interrupted, not only cause the certain economic loss to building unit, it is also big that design department is made the corresponding techniques intractability, if adopt the drilled pile tool, run into and contain rubble grain also difficulty of drilling depth when big, and the wet method holing with slurry wall protection is irritated stake, slag inclusion takes place in concrete perfusion easily under water, sediment at the bottom of necking down and the hole, construction quality is difficult for guaranteeing, is used for dry method auger boring construction, produce loosened soil at the bottom of the hole, cause bearing capacity of pile tip to reduce.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned column type, and design a kind of can be dark in groundwater table, soil property is hard, particularly contains a kind of telescopic stake tool in piling hole on the complicated ground such as layer of gravel, erratic boulder.
The utility model is achieved in that it comprises a stake pipe, and the fixedly connected sleeve in lower end of stake pipe is fixed with a pair of tube drawing otic placode on the upper end outer wall of stake pipe, and the effect of tube drawing otic placode is: by it sleeve is extracted from the stake hole.A soil-shifting piston is installed in sleeve, the upper end of soil-shifting piston is stretched in the pipe, a piston crossbeam is fixed in the upper end of soil-shifting piston, and stretch out outside the body through the fluting on the stake tube wall at the two ends of this crossbeam, in case the soil-shifting piston drops out from sleeve.The effect of soil-shifting piston is: after sleeve is pulled out from the stake hole, the soil in the sleeve is released.So just constituted this sleeve percussion drilling pore-forming stake tool.
Fig. 1 is the structure chart of this sleeve percussion drilling pore-forming stake tool;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the use principle figure of this sleeve percussion drilling pore-forming stake tool.
Below in conjunction with accompanying drawing the utility model is done and to be explained: sleeve (2), stake pipe (3) also can be rolled into by steel plate by the steel pipe manufacturing, are fixedly connected as welding between sleeve (2) and the stake pipe (3), also can adopt the bolt connection.Tube drawing otic placode (5) is welded on the upper end of stake pipe (3), and the upper port of stake pipe (3) can also be welded a reinforcing ring (6), to strengthen the impact force that stake pipe (3) bears pile monkey (11).The lower port of sleeve (2) can be fixed a cutting edge, so that strengthen the impact strength and the abrasion resistance of nozzle.The mode that can adopt welding that is connected of cutting edge (1) and sleeve (2), also can the two be fixed as one by bolt, sleeve (2) has certain thickness, can open strip cleaning eye (8) on its barrel, cleaning eye (8) can be one, also can be more than one, when being a plurality of as if cleaning eye (8), should be symmetrical on the circumference of sleeve (2).Preferably two of cleaning eyes (8) are convenient to clear up the soil in the sleeve (2) like this, and sleeve (2) can be a cylinder, also can have certain tapering, so that help bulldozing and the frictional resistance of minimizing and hole wall.Piston (4) is installed in the sleeve (2), is installed with piston crossbeam (7) on it.When piston (4) moved up and down in sleeve (2), the fluting that piston crossbeam (7) can be managed along stake on (3) wall slided up and down.The construction principle of using this telescopic stake tool is: frame is installed sleeve (2) align piles position, and the verticality of having proofreaied and correct pile frame stake pipe (3).Loosen assembly pulley (10) lifting pile monkey (11) bump pile cover.Hammer force is directly passed to the cutting edge (1) of sleeve (2) by stake pipe (3), sleeve (2) is overcome in the resistance injection foundation soil, depth of drive is the length of sleeve (2), after treating that sleeve (2) drilling depth finishes, stop hammering immediately, lifting assembly pulley (10), tension tube drawing cable wire is extracted ground with sleeve (2).Then, soil-shifting cable wire (9) is coupled on the piston crossbeam (7) of soil-shifting piston (4) upper end, continues to promote stake pipe (3), the soil in the sleeve (2) is released by soil-shifting piston (4).Again sleeve (2) is inserted in the pile hole, carry out operation circulation next time, until the design hole depth.
The said sleeve percussion drilling of the utility model drilling pile tool, concentrated the advantage of Squeezing Soil Pile and displacement pile, when its sleeve is squeezed into foundation soil, its resistance only acts on the annulus area cutting edge, and soil compaction effect is very little, can penetrate the complicated stratum such as gravel layer, cement gravel layer, erratic boulder, guarantee that the stake end accurately and reliably reaches the degree of depth and the supporting course of designing requirement, pore-forming adaptability is good, and the pore-forming regular shape, and hole wall is smooth. And easily the soil in the sleeve is discharged by the soil-shifting piston of installing in its sleeve, can improve its drilling efficiency.
The research success of this telescopic stake tool is for providing a kind of new construction method than the pile foundation construction on the complex foundation.
