Abstract
The utility model discloses a kind of structure of preventing and treating power plant building tailwater channel foundation uneven settlement, comprise covering layer basis, tailwater channel base plate and basement foundation, on covering layer basis, geosynthetics is provided with in the below of tailwater channel base plate, geosynthetics has filled hardcore bed, the utility model arranges the geosynthetics of more than layer at Riverbed surface of base, welding technology is adopted to connect between geosynthetics, and fill hardcore bed on geosynthetics surface and tamp, better can solve foundation settlement and be out of shape the concrete cracking caused, convenient construction simultaneously, economic advantages are obvious.
Description
Technical field
The utility model patent relates to a kind of structure of preventing and treating power plant building tailwater channel foundation uneven settlement, belongs to Hydraulic and Hydro-Power Engineering technical field of foundation treatment.
Background technology
At present, on many rivers in China western part, riverbed composition is mainly sand boulder and cobble deposit, Riverbed thickness is generally 10m ~ 60m, the orographic condition of part power station incorporation engineering and flow condition, usually factory building is arranged in bank or position, riverbed, for meeting base fixed and requirement for bearing capacity, main building basis is generally placed in basement foundation, and tailwater channel foundation main will be positioned on the basis of covering layer or covering layer and basement rock mixing.And if according to tectal thickness, the method process such as displacement, pile foundation are adopted for covering layer foundation main, to prevent foundation uneven settlement, but existing this treatment technology consume long in time limit, invest high, and the problem of differential settlement can't be solved completely for pile foundation.
Utility model content
The purpose of this utility model is: the soft malleability and the reinforcement effects that utilize geosynthetics, with the concentrated force disperseing load and differential settlement to produce, reach reinforcement effects, the sedimentation and deformation of better adaptation basement foundation is large, the feature of differential settlement, effectively slow down or avoid the tailwater channel bottom slab crack because basement foundation sedimentation and deformation causes, the utility model by arranging geosynthetics between tailwater channel base plate and basement foundation, geosynthetics is high-strength pulling-resisting band, there is coarse embossing on surface, by the toughness of geotextile and intensity and basement foundation or the anchoring of tailwater channel underplate concrete, mutual welding technology connects, transform the deformation condition of basement foundation as same level, better can solve the concrete cracking that basement foundation sedimentation and deformation causes, convenient construction simultaneously, economic advantages are obvious.
The utility model is achieved in that a kind of structure of preventing and treating power plant building tailwater channel foundation uneven settlement, comprise covering layer basis, tailwater channel base plate and basement foundation, on covering layer basis, be provided with geosynthetics in the below of tailwater channel base plate, geosynthetics has filled hardcore bed.
Described geosynthetics is Plastics Geogrids, steel plastic geogrid, glass fiber or polyester fiber.
Described geosynthetics termination is connected with basement foundation, and position, geosynthetics termination anchors into basement foundation inside and is not less than 1m.
Described geosynthetics termination is connected with the concrete on tailwater channel base plate, and position, geosynthetics termination anchors into tailwater channel underplate concrete inside and is not less than 1m.
1 ~ 3 layer of geosynthetics is provided with between tailwater channel base plate and covering layer basis.
Owing to have employed technique scheme, compared with prior art, the utility model arranges the geosynthetics of more than layer at Riverbed surface of base, welding technology is adopted to connect between geosynthetics, and fill hardcore bed on geosynthetics surface and tamp, better can solve foundation settlement and be out of shape the concrete cracking caused, simultaneously convenient construction, economic advantages are obvious.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment of the present utility model: a kind of structure of preventing and treating power plant building tailwater channel foundation uneven settlement, comprise covering layer basis 4, tailwater channel base plate 2 and basement foundation 5, on covering layer basis 4, be provided with geosynthetics 1 in the below of tailwater channel base plate 2, geosynthetics 1 filled hardcore bed 3.
Described geosynthetics 1 is Plastics Geogrids, steel plastic geogrid, glass fiber or polyester fiber, and the parameters such as the durability of material and tension meet industry standard.
Described geosynthetics 1 termination is connected with basement foundation 5, and position, geosynthetics 1 termination anchors into basement foundation 5 inside and is not less than 1m.
Described geosynthetics 1 termination is connected with the concrete on tailwater channel base plate 2, and position, geosynthetics 1 termination anchors into tailwater channel base plate 2 inside concrete and is not less than 1m.
1 ~ 3 layer of geosynthetics 1 is provided with between tailwater channel base plate 2 and covering layer basis 4.
The utility model prevents differential settlement structure from mainly arranging the geosynthetics of more than 1 layer at Riverbed surface of base, welding technology is adopted to connect between geosynthetics, ensure that at position, termination holder Buddhist nun lid synthetic materials anchors into basement foundation or tailwater channel underplate concrete inside is not less than 1m, to ensure the snap-in force at anchoring position.
Structure technology of the present utility model is applicable to institute's power plant building tailwater channel and is placed on the mixed base of all standing layer basis or covering layer and basement foundation, and the geosynthetics that it adopts arranges that the number of plies is specifically determined according to tectal composition and thickness.
