The present invention is the difficulty that overcomes dam joint structure design under the complex slope condition, a kind of broken line type dam joint structure is proposed, to solve the difficult problem of dam joint structure designs such as being embedded with urban sewage pipeline, large stretch of resident house, artificial slag body, sprout remittance in the side slope, reach stressed, the basic anti-requirement that blends around dam seepage flow of dam joint structure.
The technical solution adopted in the present invention is: broken line type dam joint structure, have the dam concrete gate pier, build concrete pier, the highway stone-laying barricade of bridge and built highway, it is characterized in that: between dam concrete gate pier and concrete pier concrete guard wall is set, each structural joint of this concrete guard wall is by the copper seal water shutoff; In the inboard of highway stone-laying barricade, described concrete guard wall one end is provided with the concrete key-wall with an end of having built highway.
Structural joint between described concrete guard wall and the dam concrete gate pier is handled by the copper seal water shutoff.
Structural joint between described concrete pier and the concrete guard wall is handled by the frame for movement water shutoff, this frame for movement comprise smooth concrete pier the rubber filler strip, on L shaped watertight rubber and outermost steel plate press strip, above-mentioned three is fastening by expansion bolt.
Structural joint between described concrete guard wall and the concrete key-wall is handled by the copper seal water shutoff.
The structural joint of described concrete key-wall and highway stone-laying barricade one end is handled by the frame for movement water shutoff, this frame for movement comprise smooth highway stone-laying barricade the rubber filler strip, on L shaped watertight rubber and outermost steel plate press strip, above-mentioned three is fastening by expansion bolt.
The inboard backfill waste of described concrete guard wall building stones.
The consolidation grouting hole is set, array pitch 3m, hole depth 5m on the basis of concrete guard wall.
The basis of the basis of described dam concrete gate pier, the basis of concrete guard wall, concrete key-wall and the close-connected curtain grouting of the basis instrument hole of having built highway, pitch-row 2m, hole depth extends horizontally to upstream massif basement rock to relative impervious layer.
The invention has the beneficial effects as follows: the present invention arranges the dam joint structure that a kind of broken line type is provided for the water conservancy and hydropower hinge, and advantage is that structure stress is clear and definite, construction is simple, based process is effective, can prolong seepage paths, improves around the dam impervious ability; To solving a dam joint structure processing difficult problem under urban flood defence, the reservoir complex slope condition, especially solving the main flow side has the blowdown culvert in sprout remittance or the bank slope dam joint structure design challenges, benefit of the present invention is obvious.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, present embodiment has dam concrete gate pier 2, builds concrete pier 3, the highway stone-laying barricade 5 of bridge and built highway 14, the characteristics of present embodiment are between dam concrete gate pier 2 and concrete pier 3 concrete guard wall 1 to be set, and each structural joint of concrete guard wall is by copper seal 7 water shutoffs; In the inboard of highway stone-laying barricade 5, described concrete guard wall 1 one ends are provided with concrete key-wall 4 with an end of having built highway 14.
Aspect hermetic seal, adopt copper seal 7 water shutoffs to handle for the structural joint between concrete guard wall 1 and the dam concrete gate pier 2.Adopt the frame for movement water shutoff to handle for the structural joint of building between bridge 15 concrete piers 3 and the concrete guard wall 1, see Fig. 4, this frame for movement comprise smooth concrete pier 3 rubber filler strip 9, on L shaped watertight rubber 8 and outermost steel plate press strip 10, above-mentioned three is fastening by expansion bolt 11, frame for movement is installed earlier the sidewall of concrete pier 3 is polished flat before.Adopt copper seal 7 water shutoffs to handle for the structural joint between concrete guard wall 1 and the concrete key-wall 4.Handle for the concrete key-wall 4 and the structural joint employing frame for movement water shutoff of highway stone-laying barricade 5 one ends, see Fig. 5, this frame for movement comprise smooth highway stone-laying barricade 5 rubber filler strip 9, on L shaped watertight rubber 8 and outermost steel plate press strip 10, above-mentioned three is fastening by expansion bolt 11, equally, first sidewall with highway stone-laying barricade 5 polishes flat before frame for movement is installed.
This example is utilized 12 backfills of waste building stones in concrete guard wall 1 inboard (back), increases structural stability, to satisfy the dam joint structure force request.
See Fig. 2, on the basis of concrete guard wall 1, execute and bore consolidation grouting hole 13, hole depth 5m, array pitch 3m, and carry out consolidation grouting.
See Fig. 1, Fig. 3, on the basis of dam concrete gate pier 2, on the basis of concrete guard wall 1, on the basis of concrete key-wall 4 and built to execute on the basis of highway 14 and bored the curtain grouting hole 6 of series connection mutually, hole depth is to relative impervious layer, pitch-row 2m, up to upstream massif basement rock, and carry out curtain grouting.
