Abstract
The invention relates to a method for assembling a rubber dam in a slope-shaped river channel. The method solves the long-existing problem of water leaking at the design height of the conventional slope-shaped rubber dam at present, improves unreasonable stress of dam bags and improves appearance of dam shapes. The method comprises the following steps of: 1) opening an upstream anchoring tank, a downstream anchoring tank and a top anchoring tank; 2) installing the bag edges of a downstream dam of the dam bag of the rubber dam; 3) installing the bag edges of an upstream dam of the dam bag of the rubber dam; 4) sealing both ends of the dam bag of the rubber dam, flatly overlaying ports on both ends of the dam bag, and placing the ports into the top anchoring tank; and 5) injecting water to the dam bag of the rubber dam from a water injection port to install the rubber dam. The method changes the structural form in the river channel after the rubber dam is installed, the slope part of the dam bag of the rubber dam extends downstream, cockles are formed at the positions of the horizontal section of the dam bottom and the slope section after the dam bag is aerated, and the cockles exist in downstream instead of the top of the dam bag in the conventional structure (the cockles are formed in the vertical direction).
Description
Technical field
The present invention relates to the mounting method of rubber dam, particularly the method for assembling rubber dam in the slope shape river course.
Background technology
Year surplus rubber dam is applied to modern 40 from China, rubber dam divides from dam bag and base arrangement pattern, mainly be divided into pillow formula (also being plug formula or non-headwall anchoring type) and ramp type (also being sloping core formula or headwall anchoring type), wherein traditional ramp type rubber dam at slope section anchor line arrangement form is: downstream anchor line upright projection is for to distribute with floor level Duan Weiyi straight line, the upstream anchor solidus is inflated to 45 ° of tangent lines of design height horizontal projection on slope for the dam bag, and the extension of floor level section anchor line connects to form, after the main shortcoming of this structure is the 9 water filling inflations of existing dam bag, one darker end face wrinkle 10 are arranged at the bag top, dam of corresponding river course planar base surface and junction, slope, as Fig. 5, shown in 6, upper pond level is higher when the dam, during near design height, end face wrinkle 10 positions all can some leak in various degree, make rubber dam can not really reach the purpose of design water storage level, make actual interception waterline 11 well below design interception height of water level.In addition, traditional anchor line form of structure, its floor level section is extended longer on slope, dam bag discontinuity, dam shape is not attractive in appearance yet, and transverse horizontal anchorage length in top is longer in addition, also influences visual effect.
Summary of the invention
Task of the present invention is to solve the design height seepy question that present traditional ramp type rubber dam exists always, and improves the stressed unreasonable situation of dam bag and improve the dam shape method of assembling rubber dam in slope-shaped river channel attractive in appearance.
Method of the present invention is to carry out according to the following steps:
1), offers upstream and downstream anchor slot and top anchor slot; In the bottom, river course, 2.1-11m offers the upstream and downstream anchor slot in transversal river course at interval; Wherein upstream anchor slot downstream turnover after surpassing the river course to play sloping line 0.4-0.5m, turning angle is 40-50 °; The downstream turnover after surpassing the river course to play sloping line 0.4-0.5m of downstream anchor slot, turning angle guarantees that less than the turning angle of upstream anchor slot two grooves leave level in the upper edge, river course, length is the top anchor slot of 1-1.8m;
2), the bag limit on dam, assembling rubber dam dam bag downstream; With glue in the dam bag upwards, aliging with the downstream anchor slot in the bag limit on dam, bag downstream, dam, redundance is cut, until match bag limit, dam, anchoring downstream, sealing off and covering anchorage with the downstream anchor slot;
3), the bag limit on dam, assembling rubber dam dam bag upstream; The dam bag that fixes bag limit, dam, downstream is upstream dug, behind the bag water filling space, Liuba, another side is alignd with the upstream anchor slot, redundance is cut, until match bag limit, dam, anchoring upstream, sealing off and covering anchorage with the upstream anchor slot;
4), the sealing of rubber dam bag two ends, the two side ends port of dam bag is flat folded, insert the top anchor slot; Earlier the fixing edge of updrift side port applies pulling force from the downstream direction port edge again, tightens port, and the unnecessary amount of the downstream direction port of generation is towards downstream direction, sealing off and covering anchorage;
5), by water-filling nozzle water filling in rubber dam bag, make.
The joining of described downstream anchor slot and top anchor slot is the slump point, and described top anchor slot extends 0.2-0.4m along described slump point downstream, to hold described unnecessary amount.
After rubber dam of the present invention was installed, the form of structure in the river course had had change, and the downstream is stretched at position, rubber dam bag slope, make the dam bag after inflation, the wrinkle that horizontal segment and slope fragment position form at the bottom of the dam from the bag top, dam of traditional structure, are changed into and are appeared at downstream (forming the vertical direction wrinkle).Because recessed wrinkle have been eliminated at bag top, dam, then rubber dam the situation of leaking can not occur after being inflated to design height.Spacing is less between section two anchor line of bag slope, dam, and " tall and thin shape " design all has in various degree dam bag, bottom spacer consumption and saves; Anchor structure in the rubber dam bag downstream is subjected to the force direction basically identical when making the operation of dam bag installation direction and dam bag, has reduced the dam bag and has subdued and the concentrated situation of stress.Rubber dam bag of the present invention, the horizontal direction projection is arch, with respect to the in-line structure, has higher bearing strength.
