Abstract
The utility model discloses a structure that base face is connected is built with dam abutment in induced seam bottom of arch dam, it including establish induced seam (1) bottom build to the dam abutment between the base face (2) and stitch reinforcing bar (7) and by entering thick liquid pipe (3), return pipe (4), rise the grout system that thick liquid pipe (6) and blast pipe (5) is constituteed, and seam reinforcing bar (7) is located induced seam bottom and forms the reinforcing bar net by moving about freely and quickly the reinforcing bar, by enter thick liquid pipe (3), return pipe (4), rise grout system that thick liquid pipe (6) and blast pipe (5) constitutes and dam abutment build base face (2) crossing and advance to starch manage (3), the dam facing is stretched out in return pipe (4) and blast pipe (5). The utility model discloses utilize induced seam bottom and stitch the reinforcing bar and slope grout system formation joint line face and dam abutment to build the great angle of base face crossing, avoid that induced seam face is direct builds basic shape of face one -tenth closed angle with the dam abutment, produce unfavorable stress. Guarantee that base face contacting area structure is built to induced seam bottom and dam abutment and distributing of stress is reasonable.
Description
Technical field
The utility model relates to the water retaining structure technical field in Hydraulic and Hydro-Power Engineering, specifically relates to the structure be connected with dam abutment foundation plane bottom a kind of arch dam attractive joint.
Background technology
As everyone knows, attractive joint discharges dam body tensile stress important feature in Arch Dam Structure.Because Arch Dam Abutment foundation plane design grade of side slope is comparatively steep, should form wedge angle with dam abutment foundation plane intersection bottom vertical attractive joint, attractive joint module cannot be laid, and wedge angle position easily produces unfavorable stress.
Utility model content
The purpose of this utility model is for solving prior art Problems existing, the structure be connected with dam abutment foundation plane bottom a kind of arch dam attractive joint is provided, to utilize bottom attractive joint and to stitch reinforcing bar and inclination grouting system to form seam face crossing with dam abutment foundation plane larger angle, avoid attractive joint face directly and dam abutment foundation plane form wedge angle, produce unfavorable stress.Ensure bottom attractive joint with dam abutment foundation plane contact site structure and stress distribution reasonable.
The technical solution of the utility model is as follows:
The structure be connected with dam abutment foundation plane bottom a kind of arch dam attractive joint of the present utility model, comprise bottom attractive joint between dam abutment foundation plane and the grouting system of stitching reinforcing bar and being made up of inlet pipe, return pipe, arising pipe, stack, described and stitch reinforcing bar and to be positioned at bottom attractive joint and to form steel mesh reinforcement by reinforcing bar in length and breadth, reinforcing bar model, length and an array pitch are chosen according to actual conditions.The grouting system of described inlet pipe, return pipe, arising pipe, stack composition is crossing with dam abutment foundation plane larger angle and inlet pipe, return pipe, stack stretch out dam facing, and the later stage is in the milk by inlet pipe, is in the milk in seam face closely knit.
Further, described inlet pipe, return pipe, arising pipe and stack composition grouting system face and dam abutment foundation plane angle α be greater than 50 °.
Further, described inlet pipe, return pipe, arising pipe and stack adopt coating steel pipe or pvc pipe, and an array pitch is determined according to actual, and arising pipe two ends are connected with return pipe by tee piece.
Technique effect of the present utility model:
The utility model to utilize bottom attractive joint and stitches reinforcing bar and inclination grouting system to form connecting sewing face crossing with dam abutment foundation plane larger angle, avoids the direct and dam abutment foundation plane in attractive joint face to form wedge angle, produces unfavorable stress.Ensure bottom attractive joint with dam abutment foundation plane contact site structure and stress distribution reasonable.

Description of reference numerals: 1-attractive joint, 2-dam abutment foundation plane, 3-inlet pipe, 4-return pipe, 5-stack, 6-arising pipe, 7-also stitches reinforcing bar.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, the structure be connected with dam abutment foundation plane bottom a kind of arch dam attractive joint of the present utility model, comprise bottom attractive joint 1 between dam abutment foundation plane 2 and stitch reinforcing bar 7 and by inlet pipe 3, return pipe 4, the grouting system that arising pipe 6 and stack 5 form, described and stitch reinforcing bar 7 and to be positioned at bottom attractive joint and to form steel mesh reinforcement by reinforcing bar in length and breadth, described inlet pipe 3, return pipe 4, the grouting system that arising pipe 6 and stack 5 form and inlet pipe 3 crossing with dam abutment foundation plane 2 larger angle, return pipe 4, stack 5 stretches out dam facing, later stage is in the milk by inlet pipe 3, be in the milk in seam face closely knit.
Grouting system face and the dam abutment foundation plane angle α of inlet pipe 3, return pipe 4, arising pipe 6, stack 5 composition are greater than 50 °.Inlet pipe 3, return pipe 4, arising pipe 6, stack 5 adopt coating steel pipe or pvc pipe, and an array pitch is determined according to actual, and arising pipe 6 two ends are connected with return pipe by tee piece; And stitch reinforcing bar 7 and form steel mesh reinforcement by the reinforcing bar be in length and breadth positioned at bottom attractive joint 1, reinforcing bar model, length and an array pitch are chosen according to actual conditions.
Certainly, more than just embody rule example of the present utility model, the technical scheme that the utility model also has other embodiment, all employings to be equal to replacement or equivalent transformation to be formed, all drops within the protection domain required by the utility model.
