Background
The reservoir is a main engineering measure for developing and utilizing water resources and preventing and controlling water damage. The overflow dam is a dam with flood discharge on the top of the dam, is an important component of a reservoir, is a water retaining structure and a water discharge structure, and the height of the overflow dam determines the prosperous water level and the prosperous storage capacity of the reservoir. In the northern area with poor water resources, the prosperous water level of the reservoir is improved, and then the prosperous storage capacity of the reservoir is increased, so that the runoff regulation and flood storage and depletion supplement functions of the reservoir can be greatly exerted, and the natural incoming water can better meet the requirements of water use departments in time and space. However, the increase of the elevation of the solid overflow dam will increase the flood control pressure of the reservoir, and will cause bad influence on the safety of the reservoir. The construction of the rubber dam on the overflow dam is an effective measure which can improve the reservoir capacity of the existing reservoir, realize the maximum utilization of water resources, and collapse the dam in advance before the flood comes without influencing the flood discharge of the reservoir.
The rubber dam is generally built on a river channel, a pump room is built at one end or two ends of the rubber dam, and the operation process of taking water from the river channel to fill the dam and pumping the water in the rubber dam out of the dam is realized through a water pump system. If the rubber dam built on the overflow dam adopts a traditional water filling and draining system, the selection of the position of a pump room is a difficult point, and if the rubber dam is built beside the rubber dam, because the top position of the overflow dam is higher, water cannot be pumped when the upstream water level is lower, and the rubber dam cannot be filled with water for operation; if the water level of the reservoir is changed greatly, the pump room is required to be above the check water level according to requirements, and the pump room becomes a cannon building in the reservoir, so that the water level is not attractive and is not beneficial to entering and exiting; and building downstream adds unnecessary cost and difficulty to fill rubber dams.

The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a novel rubber dam fills drainage system on overflow weir, includes the overflow dam, the rubber dam is installed at overflow dam top, the inside drain pipe that fills that is equipped with of rubber dam, it is connected with and fills water pipe and drain pipe to fill the drain pipe, it has the immersible pump to fill water piping connection, the immersible pump is in overflow dam upstream, it is nearly font near rubber dam one end to fill the water pipe, and fills the interior pressure water level that the water pipe highest point is higher than the rubber dam.
Furthermore, a rectangular support is arranged on the ground, the water filling pipe is lapped on the rectangular support to form a shape like a Chinese character 'ji', and the height of the rectangular support is higher than that of the rubber dam.
Furthermore, the rectangular support is provided with a groove which is beneficial to placing the water filling pipe.
Furthermore, a water supply well is arranged at the upstream of the rubber dam, and a submersible pump is placed in the water supply well.
Furthermore, guide walls are arranged on two sides of the rubber dam.
Furthermore, the joint of the water filling pipe, the water filling and draining pipe and the water draining pipe is provided with a tee joint.
Furthermore, a gate valve is arranged on the drain pipe.
The utility model has the advantages that: the utility model uses the submersible pump in the water collecting well to lift water and fill the rubber dam, after filling the dam, because the highest point of the water filling pipe is higher than the inner pressure water level of the rubber dam, the water will not flow backwards after stopping the pump, and no stop valve is needed; when the rubber dam needs to be collapsed, a gate valve of a drainage pipe positioned at the downstream is opened, and water in the rubber dam flows to a downstream river channel automatically, so that the collapse of the rubber dam is realized. Novel structure, easy operation, safe and reliable practices thrift the investment.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be taken as limiting the scope of the invention.
