Abstract
Disclosed is a bagged scattered solid for grout hole forming in a concrete weight body and relates to a replacement part for an embedded pipe for grout hole forming in the concrete weight body in the water conservancy and hydropower grouting project. The bagged scattered solid comprises a tubular bag and filling in the tubular bag; wherein both ends of the tubular bag are bound with sealing ropes. When in use, a drilling machine is not needed for drilling holes, the bagged scattered solid can be applicable to normal concrete and roller compacted concrete, not only solves the problem of not easy pipe pulling of the pipe pulling method, but also solves the problem that the pipe pulling method cannot be used for the roller compacted concrete, and avoids the defects of large pipe consumption by the pipe laying method.
Description
Technical field
Form the bagged loose objects of grout hole in concrete ballast body, relate to a kind ofly in the water conservancy and hydropower grouting works, the pre-buried tubing of the grout hole pore-forming in the concrete ballast body substitutes part.
Background technology
At present, in the water conservancy and hydropower grouting works, the hole forming method in the known concrete ballast body has three kinds, and they are respectively:
1, extubation: utilize steel pipe when the concrete of being built does not also finally condense, steel pipe is upwards pulled up,, form the hole, to reach the purpose of non-rig pore-forming to reach when concrete also is in plastic state.Its advantage is: without the rig pore-forming, also do not consume pre-buried tubing, saved expense.And shortcoming is: 1) operation inconvenience at the construction field (site), and consumption is artificial; 2) need operating personnel to grasp concrete time of setting well, otherwise operate just failure, and do not have the chance of 2 operations; 3) can't be used in the roller compacted concrete.
2, pipe laying method: steel pipe or plastic pipe pore-forming promptly are installed in concrete in advance.Its advantage is: simple to operate, labor intensive is few, need not rig pore-creating.Shortcoming is: expend a large amount of tubing, and also can't be used for roller compacted concrete.
3, rig port-creating method: promptly build the back that finishes and hole with rig at concrete ballast body.The method interrupts reinforcing bar easily, and it is higher to expend cost.
The said method hole is as shown in Figure 1 and Figure 2: the 4th, and Hydraulic and Hydro-Power Engineering fabric structure parting, the 5th, concrete is grout hole (also be pore-forming to be solved in the utility model partly) partly, and the 6th, concrete.
Summary of the invention
Problem to be solved in the utility model is exactly that a kind of rig boring that do not need is provided at above deficiency, can be applicable to the bagged loose objects of the formation grout hole of normal concrete and roller compacted concrete.Its technical scheme is as follows:
It comprises the filler in tubular bag and the tubular bag, pricks at the tubular bag two ends and seals rope.
The beneficial effect that compared with prior art the utlity model has is:
1, to make its diameter by the sack (polybag) of cast that sand or mud are packed into consistent with port size for the utility model, (about 30～50cm) suitable cylindric built-in fittings are to substitute the pre-buried tubing in " pipe laying method " for length and concrete (but normal concrete, also roller compacted concrete) making bed thickness, constantly stack with the rising of concreting, before concreting finishes, stack and finish.In concrete, to form the column three-dimensional core that looses, then, before grouting, with the mode of cleaning bottom of hole with sand in the hole or mud cleaning grout hole, to reach the purpose that in concrete, realizes pore-creating.
2, use the utility model both to solve " extubation " and be difficult for " tube drawing " operation, and be subjected to the difficult problem of concrete coagulating time restriction, simultaneously also solved the difficult problem that " extubation " can not be used for roller compacted concrete, the shortcoming of also having avoided " pipe laying method " to consume tubing in a large number.Simple in structure, all possessing advantage on the economy He on the operability.
3, use the utility model, do not need rig pore-creating, can avoid the direct Drilling concrete of rig, reduce the wearing and tearing of drill bit, save drill bit.
4, the utility model is adapted at pore-creating in the grinding coagulation soil body more.Because the rigidity of pre-buried tubing and protrude concrete surface, when grinding concrete construction, vibrations are ground can't be in this regional work, and makes pore-creating can't utilize " extubation " or " pipe laying method " to realize; And pre-buried bagged loose objects is semiflexible, and vibrations are ground and can be pressed, and therefore, have only pre-buried bagged loose objects just can realize pore-creating in the grinding coagulation soil body.
5, use the utility model to be not limited in concrete bodies, make grout hole, can also be used for dam in concrete (particularly at roller compacted concrete) body inverted vertical hole and the pore-forming of direct plumb line hole.Also can be used on the pore-forming of drain hole of dam gallery.

The specific embodiment
The utility model comprises the filler 3 in tubular bag 2 and the tubular bag 2, pricks at tubular bag 2 two ends and seals rope 1.Tubular bag 2 is selected polybag for use, is shaped as circle, and its length is 30-50cm, and its diameter is consistent with the diameter of grout hole.Filler 3 in the tubular bag 2 is sand or mud.
The hole forming method that utilizes the utility model to form grout hole in concrete ballast body may further comprise the steps:
1, make bagged loose objects:
1. roll of plastic being made diameter is that drilling diameter, length are the round tubular bag 2 of 30～50cm.
2. with in filler 3 (preferably sand or mud) each tubular bag of packing into, two ends are pricked and are extremely sealed with sealing rope 1 (preferably thin galvanized wire), form long 30～50cm, and diameter is the cylindric bagged loose objects 7 of drilling diameter.
2, before ballast concreting, measure the position emit pore-forming, first floor bagged loose objects 7 is placed on the position of pore-forming, making first floor concrete 6.1 (normal concrete or roller compacted concrete all are suitable for).
When 3, next layer concrete is built, repeat above program,, build i layer concrete 6.2 until placing i layer bagged loose objects 7.1.
4, after concrete rises to the grouting high level and reaches intensity, before grouting and rock pore-creating, the bagged loose objects of imbedding in the concrete is formed grout hole with high-pressure blast or water under high pressure with the grains of sand in the hole or earth cleaning back.
In making concrete process,, can correct at any time if the position of bagged loose objects is mobile to some extent.
