Abstract
The utility model discloses a connecting structure of a covering layer top panel dam-toe plate, a connecting plate and a diaphragm wall. The connecting structure comprises a concrete toe plate, the connecting plate, the diaphragm wall and a faceplate dam, wherein the connecting plate and the diaphragm wall are sequentially connected to the upstream side end face of the concrete toe plate; the faceplate dam is arranged on the downstream side end face of the concrete toe plate; the diaphragm wall is composed of a concrete slotted hole diaphragm wall section and a concrete cast-in-place wall section; the bottom end of the concrete slotted hole diaphragm wall section is inserted into a bed rock; the concrete cast-in-place wall section is poured at the top of the concrete slotted hole diaphragm wall section; on a deep covering layer of a seam area among the diaphragm wall, the concrete toe plate and the faceplate dam, backfill bedding course material and a bituminous concrete cushion are arranged from bottom to top. The connecting structure has the following advantages: through the arrangement of the backfill bedding course material and the bituminous concrete cushion below the toe plate, the joint between the toe plate and a covering layer contact surface is effectively improved, the deformation and displacement adaptive capacity is high, the seepage-proofing effect is excellent, and the basic bearing capacity of the connecting structure is improved; in addition, the deformation of the connecting plate during the storage period is reduced.
Description
Technical field
The utility model relates to the covering layer top panel dam dam foundation, especially relates to the syndeton of covering layer top panel toe plate, junction plate, impervious wall.
Background technology
Build in dark supratectal Concrete Face Rockfill Dam, be arranged on the plinth foundation that is positioned at river-bed section, traditional construction method is to adopt the covering layer of excavating its underpart that toe board is sitting on rock, causes thus covering layer excavated volume very large, especially all the more so for dark covering layer.
Summary of the invention
The utility model object is to provide the syndeton of a kind of covering layer top panel toe plate, junction plate, impervious wall.
For achieving the above object, the utility model is taked following technical proposals:
The syndeton of covering layer top panel toe plate described in the utility model, junction plate, impervious wall, comprises concrete toe board, is connected in successively the face dam of junction plate, impervious wall and the downstream end face of described concrete toe board upstream side end face; Described impervious wall inserts the concrete slotted eye impervious wall section in basement rock by bottom, and is cast in the concrete cast-in-situ wall section formation at described concrete slotted eye impervious wall section top; Be positioned at impervious wall to the dark covering layer in concrete toe board and region, joint of CFRD place, be provided with backfill bedding material and bituminous concrete bed course from bottom to top; The thickness of described backfill bedding material is 8m-12m; The thickness of described bituminous concrete bed course is 0.7m-1.2m; The height of described concrete cast-in-situ wall section is 1.2m-1.8m.
The utility model advantage is by bituminous concrete bed course and backfill bedding material are set below toe board, effectively improved being connected of toe board and covering layer contact surface, and adaptive deformation displacement capacity is strong, and good seepage-proof property has improved the bearing capacity on this basis, position.Concrete slotted eye impervious wall upper end is cut to after-pouring and become concrete cast-in-situ wall, concrete junction plate is connected more solid and reliable with building of concrete cast-in-situ wall, reduced the distortion at retaining phase junction plate simultaneously.
Brief description of the drawings
Fig. 1 is syndeton schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the syndeton of covering layer top panel toe plate described in the utility model, junction plate, impervious wall, comprise concrete toe board 1, be connected in successively the face dam 2 of junction plate 9, impervious wall and the downstream end face of described concrete toe board 1 upstream side end face; Described impervious wall inserts the concrete slotted eye impervious wall section 4 in basement rock 3 by bottom, and the concrete cast-in-situ wall section 5 that is cast in described concrete slotted eye impervious wall section 4 tops forms; Be positioned at impervious wall to the dark covering layer 6 in concrete toe board 1 and face dam 2 seam crossing regions, be provided with backfill bedding material 7 and bituminous concrete bed course 8 from bottom to top; The thickness of described backfill bedding material 7 is selected between 8m-12m according to covering layer composition situation; The thickness of described bituminous concrete bed course 8 is selected between 0.7m-1.2m; The height of described concrete cast-in-situ wall section 5 is selected between 1.2m-1.8m, and its end face flushes with the end face of concrete toe board 1 junction.
