Abstract
The utility model relates to a novel seepage-proofing model for a concrete surge tank for a hydropower station. The novel seepage-proofing model comprises a shaft lining and a concrete waterproof material layer arranged on the inner surface of the shaft lining. According to the novel seepage-proofing model for the concrete surge tank for the hydropower station, which is disclosed by the utility model, the concrete waterproof material layer is arranged on the surface of the finished surface of the surge tank, so that the aim of improving the seepage-proofing performance of lining concrete is achieved.
Description
Technical field
The utility model relates to field of water conservancy, relates in particular to that to be suitable for ROCK CONDITIONS relatively poor, the novel antiseepage pattern of concrete surge shaft of the thicker and outer side slope of next-door neighbour of lining cutting.
Background technology
General surge shaft antiseepage only depends on concrete lining or reinforced concrete lining layer to accomplish; But see according to having built the hydroelectric station operation situation at present; As concrete lining thicker (greater than 1.0m), and lining construction is easy to generate the concrete cracking phenomenon when second-rate; Then destroy leakage preventing structure, cause surge shaft " interior water exosmoses ".And the relatively poor and next-door neighbour of wall rock condition is during side slope around the surge shaft, and " interior water exosmoses " will can cause the side slope unstability in the time of seriously to the stable deleterious impact of side slope.Usually after " interior water exosmoses ", intractability is bigger.Present conventional way is: through means such as chemical groutings, lining cutting inner surface crack is repaired, treatment effect is generally not ideal, and the chemical grouting expense is higher, also can produce certain destruction to environment.
The utility model content
The purpose of the utility model provides a kind of good novel antiseepage pattern of surge shaft of barrier performance of lining concrete, and this antiseepage pattern can reduce the risk that " interior water exosmoses " jeopardized side slope.
To achieve these goals, the technical scheme of the utility model employing is following:
The novel antiseepage pattern of the concrete surge shaft that is used for the power station of the utility model comprises lining shaft and the concrete water-proof material layer that is provided with at the inner surface of described lining shaft.
Preferably, described concrete water-proof material layer is arranged on the inner surface of the said lining shaft below the surge shaft ordinary water level.
Preferably, described concrete water-proof material layer is made up of two-layer waterproofing materials.
Preferably, described concrete water-proof material layer adopts cementitious capillary waterproofing material to process.
The beneficial effect of the utility model is following:
The novel antiseepage pattern of the concrete surge shaft that is used for the power station of the utility model is passed through at completed surge shaft lining cutting inner surface; The concrete water-proof material layer is set reaches the purpose that improves the lining concrete barrier performance; Compare with the mode (that is: on surge shaft lining shaft surface, only chemical grouting being carried out in macroscopic crack) that handling behind the crack appears in tradition again, the utility model carries out system lock, good seepage-proof property to the lining concrete surface; And the concrete water-proof material also has good endurance; Nontoxic, the construction period is short, cheap characteristics.The surge shaft of the utility model is compared with other engineerings of not doing antiseepage on surge shaft lining cutting surface, and the lining cutting barrier performance improves a lot, and is with the obvious advantage.
Description of drawings
Fig. 1 is the novel antiseepage type structure of the concrete surge shaft sketch map that is used for the power station of the utility model instance.
1, surge shaft lining shaft, 2, the concrete water-proof material layer.
The specific embodiment
Further describe below in conjunction with accompanying drawing and specific embodiment technical scheme and beneficial effect the utility model.
The novel antiseepage pattern of the concrete surge shaft that is used for the power station of the utility model is that the inner surface at lining shaft is provided with the concrete water-proof material layer; This waterproof layer can be made up of one deck waterproofing materials; Also can constitute, can certainly constitute by the waterproofing materials of multilayer by two-layer waterproofing materials.The embodiment of accompanying drawing 1 for constituting by two-layer waterproofing materials; It is provided with the concrete water-proof material layer 2 that is made up of two-layer waterproofing materials on the inner surface of surge shaft lining shaft 1; Two-layer waterproof layer is set the lining cutting external coating is not omitted, thereby guaranteed the impervious barrier construction quality.
The concrete water-proof material layer can adopt cementitious capillary waterproofing material also can adopt other similar materials; Adopting cementitious capillary waterproofing material is that the active chemistry that contains in the material permeates to inside concrete through carrier after utilizing cementitious capillary waterproofing material and water effect, in concrete capillary channel or slit, forms water-fast acicular crystals; The filling capillary channel; Make concrete fine and close,, through the relatively poor lining concrete of construction quality is repaired; Improve its anti-permeability performance, thereby reach the purpose that prevents that " interior water exosmoses " jeopardized side slope safety.
Claims (4)
1. the novel antiseepage pattern of concrete surge shaft that is used for the power station comprises lining shaft, it is characterized in that, is provided with the concrete water-proof material layer at the inner surface of described lining shaft.
