Description of drawings
Fig. 1 is the schematic diagram of a kind of job practices that prevents erosion of the present invention.
The specific embodiment
In order to make technological means of the present invention, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Fig. 1 is the schematic diagram of a kind of job practices that prevents erosion of the present invention, sees also shown in Figure 1.A kind of job practices that prevents erosion of the present invention, at first by the auger 1 chamber top board 21 of being driven underground, and directly enter basement bottom board 22 faces are holed, form a mechanical tapping 221, one highly is embedded in the perforate 221 for the lower joint sleeve 32 of 500mm, and will seal between lower joint sleeve 32 and basement bottom board 22 perforates 221 by meeting water rapid condensation material, add stifled effect as sealing.This time joint sleeve 32 can adopt seamless steel pipe or pvc pipe, and simultaneously, the upper end of lower joint sleeve 32 is fixedly connected with joint sleeve 31 on by a flange 4, and joint sleeve 31 adopts seamless steel pipe or pvc pipe on this; Then the upper end with upper joint sleeve 31 is connected in the through hole of basement roof 21, and the upper joint sleeve 31 and the lower joint sleeve 32 that then are connected by 1 pair of auger carry out the secondary drill hole of drilling machine, and upper joint sleeve 31 and lower joint sleeve 32 are got through, and forms a boring 33; Injected water with hydraulic pressure in the balancing sleeve, prevents that underground Shuitu from influxing in the basement 2 to sleeve from the boring 33 at upper joint sleeve 31 tops again.At last, auger 1 carries out bore forming in 21 pile foundation drill bits of basement roof stretch to joint sleeve 31 and lower joint sleeve 32, simultaneously, carry out the 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 referring to shown in Figure 1.Further, the chance water rapid condensation material that is used between the lower joint sleeve 32 of sealing and basement bottom board 22 perforates 221 can adopt rapid setting cement to add stifled materials as sealing.
Further, the bar head that boring 33 orifice diameter that the upper joint sleeve 31 that is connected by 1 pair of auger and lower joint sleeve 32 form are bored greater than pile foundation.And this boring 33 penetrates deck and the bed course of basement bottom board 22.
Further, lower joint sleeve 32 is installed joint sleeve 31 at once by flange 4 on basement roof 21, and overhead height of joint sleeve 31 needs greater than the Groundwater grease head highness on this.
Further, carry out the construction of stake top after upper joint sleeve 31 and basement roof 21 is fixing, a distance of constructing to the soffit of basement bottom board 32 in the stake top is 500mm.
Further, the cement-soil jet grouting pile construction that carries 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, it is the steel pipe of 325mm that Construction of High Pressure Jet Grouting Pile adopts diameter, and the nozzle by High Rotation Speed sprays into basement bottom board 22 times with cement paste and mixes mutually the cement stabilization body of formation lap connection with soil layer.It is the steel pipe of 325mm that the compaction grouting construction can be adopted diameter, utilizes hydraulic principle by steel pipe slurries to be injected into basement bottom board 22 times equably, and slurries are with filling, infiltration and compacted extruding moisture and air, with integral body of cementing formation.And comprehensive high-pressure injection engineering method pile driving construction to adopt diameter be the steel pipe of 400mm, by managing the means of interior pressure plasma discharge, basement bottom board is regulated and control for 22 times, can significant less construction to the disturbance of surrounding enviroment, guarantee the effect of construction.
In sum, the job practices of using the present invention to prevent erosion, owing to adopt groundwater pressure under mechanical tapping, the pipe inner equilibrium base plate, effectively the soil erosion in the control pile foundation construction process is on-the-spot, guarantee safety of surrounding environment, and cement-soil jet grouting pile construction quality, both satisfied construction safety and progress, reduce construction cost from measure again, guaranteed whole construction speed; Simultaneously, the present invention is simple to operate, and cost is low, is easy to popularization and application, especially is fit to various basement pile foundation reconstruction constructions.
More than show and described basic 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; that describes in above-described embodiment and the 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.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
