Abstract
The grout injection equipment after pile side of compresol pile includes grouting steel conduct pipe vertically attached to the pile body reinforcing cage, upper end portion of said grouting steel conduct pipe is communicated with ground high-pressure grout-conveying flexible pipe, and the lower end portion of said grouting steel conduct pipe is communicated with reinforced PVC flexible pipe, and the reinforced PVC flexible pipe is connected with grouting one-way valve. Because the grouting equipment is positioned outside pile soil boundary, the grouting points can be reasonable arranged according to the pile side soil layer, and have no need of breaking through pile body concrete protection layer. It can enhance pile side resistance and can greatly raise load-bearing capacity.
Description
In construction work, the castinplace pile Piles for Friction Piles that belong to based on pile side friction in order to reinforce the soil body of a side mud skin and certain limit, strengthen pile side resistance more, can take the device of rear flank slip casting and technology.Existing grout pile side grouting device is the slip casting steel conduit of vertical sclerozone grouting valve on the pile body reinforcing cage; it is the internally-arranged type grouting device; during slip casting; need break through the pile concrete topping and implement slip casting; and must slip casting in two days behind pile; just in time intersect, cause working procedure mixed and disorderly, also can stay hidden danger to reinforcement corrosion simultaneously because of breaking through the pile body topping with the pile operation.
The purpose of this invention is to provide a kind of side rear grouting of compresol pile device that can significantly improve the bearing capacity of stake, avoid the pile cross-operation, avoid the hidden danger of pile body reinforcement corrosion.
The technical scheme of side rear grouting of compresol pile device of the present invention: this device comprises vertically attached to the slip casting steel conduit on the pile body reinforcing cage, the defeated slurry of slip casting steel conduit upper end and ground high pressure soft pipe connection, it is characterized in that: slip casting steel conduit lower end all with reinforcement PVC soft pipe connection, be distributed with the slip casting one way valve on the reinforcement PVC flexible pipe.
Above-mentioned reinforcement PVC hose loop is to being the petal reinforcing cage outside that is arranged in, and petal protrudes the position establishes the slip casting one way valve.Pegging graft with reinforcement PVC flexible pipe through the inverted T shape three-way interface and be communicated with in slip casting steel conduit bottom, forms closed circuit.
The vertical undulate of above-mentioned reinforcement PVC flexible pipe arranges that its trough is fixed by finer wire and precast reinforced cage colligation, and its crest place establishes the slip casting one way valve.Reinforcement PVC flexible pipe is vertically arranged 2～6 along the long undulate of stake.
Above-mentioned slip casting one way valve is to be arranged circumferentially 1～2 row's injected hole on reinforcement PVC flexible pipe, lays the movable span cap on injected hole, outer coated rubber strip and adhesive waterproof tape.
Movable span cap on the injected hole can be drawing pin or steel ball, and rubber strip is the rubber pneumatic tyre.
This side rear grouting of compresol pile technology, it is characterized in that: behind pile, implement harmless concrete grouting in 2～30 days, reinforce the soil body of stake side mud skin and certain limit, injection slurry is at the interface implemented slip casting through slip casting steel conduit, reinforcement PVC flexible pipe and slip casting one way valve at stake soil by the defeated slurry of ground high pressure flexible pipe.The slurry water gray scale is according to the classification of soil and whether water saturation is determined:
The water/binder ratio of mud, muddy soft soil and saturated medium coarse sand, gravelly sand, ovum gravel is 0.45～0.55;
The water/binder ratio of saturated general cohesive soil, silt, powder fine sand is 0.50～0.65;
The water/binder ratio of the general cohesive soil of unsaturation, silt, powder fine sand, medium coarse sand, gravelly sand, ovum gravel is 0.70～0.90.In slurries, can add 1～4% Admixture.
Advantage of the present invention: because grouting device is to be in an externally positioned type of pedosphere face; can be according to stake side soil layer reasonable Arrangement slip casting point; improve grouting consolidation effect; need not to break through the pile concrete topping and implement slip casting; thereby needn't slip casting in 2 days behind pile; avoid intersecting with the pile operation, simultaneously also not reason break through the pile body topping and stay hidden danger to reinforcement corrosion.Different classes of and moisture situation according to soil is determined the slurry water gray scale, reaching best consolidation effect, thereby strengthens pile side resistance, significantly improves the bearing capacity of stake.Be respectively through the enhancing amplitude of stake rear flank slip casting to pile side resistance: mud, muddy soft soil are 20～30%, and general fine grained soils (cohesive soil, silt, powder fine sand) is 30～60%, and coarse-grained soil (ovum gravel, gravelly sand, medium coarse sand) is 80～200%.It is not impaired that the slip casting one way valve can bear deep layer high water head pressure, prevents from that silt from pouring in the pipe to stop up, and can make slurries discharge smoothly and do not reflux again.Be applicable to slurry drilled pile, steel sleeve retaining wall castinplace pile and dried operation castinplace pile.
Below in conjunction with drawings and Examples the present invention is described in detail:
Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is Fig. 1 I-I generalized section;
Fig. 3 is the enlarged diagram of Fig. 2 node A;
Fig. 4 is the enlarged diagram of Fig. 2 Node B;
Fig. 5 is the structural representation of the embodiment of the invention two;
Fig. 6 is the schematic diagram of Fig. 5 II-II section.
The side rear grouting of compresol pile device, comprise vertically attached to the slip casting steel conduit 2 on the pile body reinforcing cage 1, the defeated slurry of slip casting steel conduit 2 upper ends and ground high pressure soft pipe connection, slip casting steel conduit bottom is communicated with reinforcement PVC flexible pipe 3, establishes slip casting one way valve 4 on the reinforcement PVC flexible pipe 3.Slip casting one way valve 4 is arranged circumferentially 1～2 row's injected hole on reinforcement PVC flexible pipe 3, lay drawing pin 6 or steel ball 5 on injected hole, outer coated rubber pneumatic tyre 7 and adhesive waterproof tape 8.
By Fig. 1～4 as seen, embodiment one is an A type side rear grouting of compresol pile device, and reinforcement PVC flexible pipe 3 hoops are petal reinforcing cage 1 outside that is arranged in, and petal protrudes the position establishes slip casting one way valve 4.Slip casting steel conduit 2 bottoms are inverted T shape threeway cone-shaped interface 9, and pegging graft with reinforcement PVC flexible pipe 3 is communicated with, and forms closed circuit.The projection of flexible pipe protrudes reinforcing cage 1 outer rim 15～20cm, and protuberance sets up unidirectional grout valve 4 separately.
