Abstract
The invention discloses a method and a structure for plugging a karst pipeline, wherein soybeans (4) and quick-setting mortar (3) are mixed, stirred and coated in a film bag (2) and are placed at a leakage point inlet of the karst pipeline (1), the soybeans (4) expand the volume in the film bag (2) by utilizing the self expansibility before the quick-setting mortar (3) is solidified, the quick-setting mortar (3) is quickly solidified while the volume of the film bag (2) expands, and the film bag (2) is tightly attached to the periphery of the karst pipeline (1) after the quick-setting mortar (3) is solidified to generate friction and stop flowing, so that the aim of plugging the karst pipeline (1) is fulfilled. The invention not only has small construction technical difficulty, simple construction process and low investment, but also achieves good leaking stoppage effect, and can be widely popularized and applied in the technical field of leaking stoppage of karst pipelines.
Description
Technical field
The present invention relates to a kind of blocking method for karst and film pocket type leak stopping structure, belong to Hydraulic and Hydro-Power Engineering technical field.
Background technology
In the regional hydroelectric projects such as current Guizhou, Guangxi, it is limestone when basis when water retaining structure is seated lithology, often limestone is grown more karst, for preventing karst generation Seepage, generally take karst to carry out antiseepage grouting, when karst cavity is larger, take chemical grouting.In the time taking antiseepage grouting, generally dense mortar or pea gravel concreten are injected to karst by grouting equipment, in the time that karst seepage velocity is higher, above leaking-stopping measure often ends in failure, and traces it to its cause, when after dense mortar or pea gravel concreten injection karst, the diluting effect being seeped water, dense mortar or pea gravel concreten are difficult to solidify within a short period of time, and its main component cement is taken away by infiltration, even if leave part microlith in karst, be still difficult to reach the object of leak stopping; In the time that karst cavity is large and seepage velocity is very large, generally take chemical grouting, its grouting agent has water glass, acrylates, soluble polyurethane, elastic polyurethane and lignin slurry etc., its impervious leakage-stopping is respond well, but grouting agent is expensive, and chemical grouting construction difficulty is larger, working procedure complexity, in filling process, easily produce chemical poisoning, security risk is large.Therefore, existing karst leaking-stopping measure is dissatisfactory.
Summary of the invention
The object of the present invention is to provide a kind of blocking method for karst and structure, to overcome the deficiencies in the prior art.
Technical scheme of the present invention is such: it is a kind of blocking method for karst, it adopts a kind of film pocket type leak stopping structure, this film pocket type leak stopping structure is by soya bean and quick-setting mortar mix and blend and is coated in a film bag and is positioned over the breakthrough import of karst, film bag can be subject to the induced effect of seepage flow current and get into the breakthrough of karst, and in this process, soya bean utilized the dilatancy of self that film bag inner volume is expanded before quick-setting mortar solidifies, when the long-pending generation of film bag is expanded, quick-setting mortar solidifies rapidly, quick-setting mortar solidifies caudacoria bag and karst periphery is fitted consolidation and produces frictional force and stop flowing, thereby reach the object of karst leak stopping.This leak stopping mode, is to utilize the mobility of seepage flow self to remove to block seepage flow, therefore has good guidance quality.
Therefore, the present invention has adopted such karst film pocket type leak stopping structure, it is in the breakthrough import of karst, at least one to be set can produce mobile film bag with current, and film bag is enclosed construction, is coated with the soya bean and the quick-setting mortar that mix together in film bag.Certainly, in film bag, the ratio of quick-setting mortar and soya bean is also very important in the technical program, as less in soya bean, be difficult to make film bag to obtain larger dilatancy, and soya bean is more, may causes again film bag to be damaged, or cause the rapid hardening effect of quick-setting mortar bad.Consider, preferred, in each film bag, the mass ratio of quick-setting mortar and soya bean is 3:1～10:1.In addition, film bag is preferably the closed bag shaped structure that natural rubber is made, and also can adopt artificial rubber or other material with high fluidity, pliability and water resistance to make.Film bag shape is preferably flat bag like construction, and its one end or two ends are provided with tip.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention is meeting under the prerequisite of leak stopping requirement, and film bag has high fluidity, pliability and water resistance, not only can fill the different large areolas of karst, and can not punctured by stone tooth, and inner quick-setting mortar and soya bean can not be overflowed.Secondly, soya bean can cause film bag to produce large volume expansion after mixing quick-setting mortar, and quick-setting mortar possesses compared with high viscosity, can solidify rapidly in expanding film bag is long-pending, cause film bag and karst periphery laminating consolidation and produce frictional force and stop flowing, infiltration cannot be released karst, thereby reach the object of karst leak stopping.The present invention not only construction difficulty is little, and working procedure is simple, and reduced investment has also reached good plugging effect, can be in karst leakage stopping technology field wide popularization and application.
brief description of the drawings
Fig. 1 is film pocket type leak stopping structure schematic diagram of the present invention.
Description of reference numerals: 1-karst, 2-film bag, 3-quick-setting mortar, 4-soya bean.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention implements like this: as shown in Figure 1, the present invention mainly adopts a kind of film pocket type leak stopping structure, this film pocket type leak stopping structure, outside is a film bag 2, film bag 2 has soft quality, and has good stretch-resistance and enough intensity, and also must have water proofing property, therefore the selection of material is important, conventionally adopts the film that natural rubber is processed into make.In film bag 2, pack the soya bean 4 and quick-setting mortar 3 of mix and blend into, then after film bag 2 being sealed, be placed on the seepage mouth of karst 1, like this, soya bean 4 utilized the dilatancy of self that film bag 2 inner volumes are expanded before quick-setting mortar 3 solidifies, and film bag 2 can be constantly under the drive of seepage flow be got into towards the seepage mouth in karst 1, simultaneously, when film bag 2 volumes produce expansion, quick-setting mortar 3 solidifies rapidly, quick-setting mortar 3 solidifies caudacoria bag 2 and produces frictional force and stop flowing with karst 1 periphery laminating consolidation, thereby reach the object of karst 1 leak stopping.
In order to make film bag 2 can clamp-on better the trickle seepage mouth of karst 1, film bag 2 can adopt flat structure, and its one end or two ends are provided with tip, like this along with film bag 2 flow, block more easily trickle seepage mouth.
Certainly, in the present invention, soya bean also can adopt other beans to replace, or adopts other to have the material replacement of meeting the slow expansion of water.
Certainly, be more than concrete exemplary applications of the present invention, the present invention also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on protection domain of the presently claimed invention.
