Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of construction method prevented erosion of the present invention.
Detailed description of the invention
In order to make technological means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
Fig. 1 is the schematic diagram of a kind of construction method prevented erosion of the present invention, shown in Figure 1.A kind of construction method prevented erosion of the present invention, first to be driven underground room top board 21 by auger 1, and directly enter and holed in basement bottom board 22 face, form a mechanical tapping 221, one highly for the lower joint sleeve 32 of 500mm is embedded in perforate 221, and closing between lower joint sleeve 32 and basement bottom board 22 perforate 221 by meeting water rapid condensation material, adding stifled effect as sealing.This lower joint sleeve 32 can adopt seamless steel pipe or pvc pipe, and meanwhile, the upper end of lower joint sleeve 32 is fixedly connected with on one by a flange 4 saves sleeve 31, and on this, joint sleeve 31 adopts seamless steel pipe or pvc pipe; Then the upper end of upper joint sleeve 31 is connected in the through hole of basement roof 21, then by auger 1, secondary drill hole of drilling machine is carried out to the upper joint sleeve 31 be connected and lower joint sleeve 32, upper joint sleeve 31 and lower joint sleeve 32 are got through, form a boring 33; From the boring 33 at upper joint sleeve 31 top, inject water in sleeve again, with hydraulic pressure in balancing sleeve, prevent underground Shuitu from influxing in basement 2.Finally, auger 1 stretches to save in sleeve 31 and lower joint sleeve 32 at basement roof 21 pile foundation drill bits and carries out bore forming, meanwhile, carries out cement-soil jet grouting pile construction 22 times at basement bottom board.
The present invention also has following embodiment on the basis of the above:
Please continue shown in Figure 1.Further, rapid setting cement can be adopted to add stifled materials as sealing for closing lower chance water rapid condensation material between joint sleeve 32 and basement bottom board 22 perforate 221.
Further, by auger 1, boring 33 orifice diameter that the upper joint sleeve 31 be connected and lower joint sleeve 32 are formed is greater than to the bar head of pile foundation brill.Further, this boring 33 penetrates deck and the bed course of basement bottom board 22.
Further, lower joint sleeve 32 installs joint sleeve 31 at once by flange 4 on basement roof 21, and on this, the overhead height of joint sleeve 31 need be greater than Groundwater grease head highness.
Further, after fixing to upper joint sleeve 31 and basement roof 21, carry out the construction of stake top, the stake top distance of construction to the soffit of basement bottom board 32 is 500mm.
Further, the cement-soil jet grouting pile construction carried out for 22 times at basement bottom board includes Construction of High Pressure Jet Grouting Pile, compaction grouting construction and comprehensive high-pressure injection engineering method pile driving construction.Wherein, Construction of High Pressure Jet Grouting Pile adopts diameter to be the steel pipe of 325mm, by the nozzle of High Rotation Speed, cement paste is sprayed into basement bottom board and mixes mutually with soil layer for 22 times, forms the cement stabilization body of lap connection.Compaction grouting construction can adopt diameter to be the steel pipe of 325mm, utilizes hydraulic principle, by steel pipe, slurries are injected into basement bottom board 22 times equably, slurries to fill, infiltration and compacted extruding moisture and air, with cementing formation entirety.And comprehensive high-pressure injection engineering method pile driving construction adopts diameter to be the steel pipe of 400mm, by managing the means of interior pressure plasma discharge, basement bottom board being regulated and controled for 22 times, significantly less construction to the disturbance of surrounding enviroment, the effect of construction can be ensured.
In sum, use the construction method that the present invention prevents erosion, due to groundwater pressure under employing mechanical tapping, pipe inner equilibrium base plate, soil erosion in effective control pile foundation construction process is on-the-spot, guarantee safety of surrounding environment, and cement-soil jet grouting pile construction quality, both met construction safety and progress, reduce construction cost from measure again, ensure that whole construction speed; Meanwhile, the present invention is simple to operate, and cost is low, is easy to popularization and application, is especially applicable to various basement pile foundation reconstruction construction.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
