Abstract
The utility model discloses a kind of deeply covered layer seepage prevention of dam founda wall construction, comprise the concrete slotted eye impervious wall be arranged between left and right bank on riverbed basement rock, in insertion riverbed, the bottom basement rock of concrete slotted eye impervious wall; Linking is fixed on the top of concrete slotted eye impervious wall concrete cast-in-situ wall; Concrete cast-in-situ wall is fixedly connected with left and right bank basement rock respectively by cast-in-situ concrete High-toe wall its underpart with the left and right two ends of concrete slotted eye impervious wall, and its top is fixedly connected with left and right bank concrete junction plate; Left and right bank concrete junction plate is fixedly connected with left and right bank basement rock respectively with by left and right bank toe board.The utility model advantage is the local penetration destruction solved because concrete slotted eye impervious wall construction mass defect causes.
Description
Technical field
The utility model relates to seepage prevention of dam founda wall construction, especially relates to deeply covered layer seepage prevention of dam founda wall construction.
Background technology
Build the Concrete Face Rockfill Dam on deeply covered layer, its Riverbed seepage control measure is by squeezing into covering layer by concrete slotted eye impervious wall and inserting in basement rock, block the current in the dam foundation, concrete slotted eye impervious wall upper end is closely connected by junction plate with the toe board of face dam, form seepage prevention for deep covering system, prevent the current under high water head effect from permeating with this.The end be connected with left and right bank basement rock due to the slotted eye impervious wall in covering layer and the bad control of upper end construction quality, cause concrete slotted eye impervious wall often easily to produce local quality defect.
Summary of the invention
The utility model object is to provide a kind of deeply covered layer seepage prevention of dam founda wall construction.
For achieving the above object, the utility model takes following technical proposals:
Deeply covered layer seepage prevention of dam founda wall construction described in the utility model, comprises the concrete slotted eye impervious wall be arranged between left and right bank on riverbed basement rock, and the bottom of described concrete slotted eye impervious wall is inserted in described riverbed basement rock; Linking is fixed on the top of described concrete slotted eye impervious wall concrete cast-in-situ wall; Described concrete cast-in-situ wall is fixedly connected with left and right bank basement rock respectively by cast-in-situ concrete High-toe wall its underpart with the left and right two ends of concrete slotted eye impervious wall, and its top is fixedly connected with described left and right bank concrete junction plate; Described left and right bank concrete junction plate is fixedly connected with left and right bank basement rock respectively with by left and right bank toe board.
The utility model advantage is the concrete cast-in-situ wall being fixedly engaged on described concrete slotted eye impervious wall top, thus solves the local penetration destruction because concrete slotted eye impervious wall construction mass defect causes.Concrete cast-in-situ wall is fixedly connected with described left and right bank concrete junction plate respectively by cast-in-situ concrete High-toe wall with the left and right two ends of concrete slotted eye impervious wall, not only improve being connected of concrete slotted eye impervious wall top and toe board, adaptive deformation displacement capacity is strong, good seepage-proof property, also make together with junction plate is cast in concrete cast-in-situ wall with concrete slotted eye impervious wall more securely simultaneously, make dam body more abundant at the deformation displacement of construction period, the distortion of such retaining phase junction plate can reduce a lot.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, deeply covered layer seepage prevention of dam founda wall construction described in the utility model, comprises the concrete slotted eye impervious wall 1 be arranged between left and right bank on riverbed basement rock 5, and the bottom of described concrete slotted eye impervious wall 1 is inserted in described riverbed basement rock 5; The top of described concrete slotted eye impervious wall 1 is fixed and is connected that to have be highly the concrete cast-in-situ wall 3 of a meter; Described concrete cast-in-situ wall 3 is fixedly connected with left and right bank basement rock 5 respectively by cast-in-situ concrete High-toe wall 2.1,2.2 its underpart with the left and right two ends of concrete slotted eye impervious wall 1, and its top is fixedly connected with described left and right bank concrete junction plate 4.1,4.2; Described left and right bank concrete junction plate 4.1,4.2 is fixedly connected with left and right bank basement rock respectively with by left and right bank toe board.
