Summary of the invention:
The problem to be solved in the present invention is exactly provide a kind of reliable in quality, easy construction for above deficiency, for the orifice tube of water burst hole section castingin, and its construction method.Its technical scheme is as follows:
It has body, its key technology is set with the first grout stop and the second grout stop at the upper and lower end of body stage casing outer wall, be wound around the rope made of hemp or cotton yarn at the first grout stop outer wall, the upper and lower end wall of body stage casing between the first grout stop and the second grout stop arranged respectively a circle first portals and second to portal.
The embedding method of water burst hole section orifice tube, comprises the following steps:
1) infiltration in grout hole is caused the distance beyond the 10cm of aperture;
2) grout hole first paragraph is in the milk by grouting technique requirement;
3) in grout hole, divide into orifice tube, mouth of pipe hoop exposes aperture;
4) at the annular spaces part perfusion mortar between the orifice tube outer wall and grout hole at the first grout stop place, by mortar vibration compacting, mortar is concordant with the aperture of grout hole;
5) after the mortar final set 24h of perfusion, the cement paste of 0.5:1 is adopted to pour into orifice tube through mouth of pipe hoop;
6) orifice tube is airtight and treat solidifying 48h, and orifice tube castingin completes.
Compared with prior art, the beneficial effect that the present invention has is:
1, product of the present invention need not holed in orifice tube side direction of holing specially separately, does not need to install grouting nozzle and plastic flexible pipe, is applicable to any direction (360 °) boring, and construction technique is simpler, more effectively.
2, product of the present invention is upper body stage casing outer wall, lower end is set with the first grout stop and the second grout stop, the rope made of hemp or cotton yarn is wound around at the first grout stop outer wall, upper in body stage casing between the first grout stop and the second grout stop, lower end wall is arranged respectively a circle first portals and second to portal, can bear high pressure (can normal mounting when aperture nature water burst pressure reaches 0.3MPa, after installation, the maximum pressure that bears can reach 4.0MPa, be applicable to be greater than 3.0MPa high pressure grouting), efficiently solve the difficult problem always perplexing castingin orifice tube under large water burst condition for many years.
3, slip casting does not need process grouting nozzle and plastic flexible pipe after completing, free from environmental pollution.
4, the orifice tube that this orifice tube is specially adapted under the large water burst condition in aperture that dam engineering 133m head difference causes is installed, and bears the curtain grouting pressure of 3.5MPa.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is grout stop structural representation of the present invention.
Detailed description of the invention
See Fig. 1 and Fig. 2, the present invention has body 7, its key technology is set with the first grout stop 10 and the second grout stop 6 at the upper and lower end of body 7 stage casing outer wall, the rope made of hemp or cotton yarn 3 is wound around at the first grout stop 10 outer wall, its effect is the rope made of hemp or cotton yarn water-swellable, can bear design grouting pressure while good airtight grout stop lower end drilling hole in water burst; The upper and lower end wall of body 7 stage casing between the first grout stop 10 and the second grout stop 6 being arranged, a circle first portals respectively and 4 and second portals 5, for the spilling of slurries or water.
Described body 7 top is provided with mouth of pipe hoop 1.
The upper edge hole L of described first grout stop 10 to body 7
