Description
Technical Field
The utility model belongs to the technical field of the stagnant water technique among the hydraulic engineering and specifically relates to a stagnant water structure that is used for fluffy formula cofferdam adjacent panel under water between.
Background
After a large water delivery channel (such as a south-to-north water diversion main canal with designed water depth up to 7 m) runs for a certain time, the condition that the side slope is damaged and needs to be repaired inevitably occurs. Because the main canal runs by a single line, the main canal does not have the condition of water cut-off maintenance, and a method for repairing the underwater dry land by building a cofferdam is mostly adopted. For the tent cofferdam shown in fig. 1 and 2, panels are laid on the top surface and the outer three vertical surfaces of the steel truss. In order to ensure that the cofferdam and the channel are mutually isolated and form a watertight space to meet construction conditions, a water stopping structure is required to be arranged at the splicing part of the panels. At present, in water stop of a steel gate in hydraulic engineering, a mode that P-type, I-type or L-type water stop rubbers are installed at three side edges of a top leakage type steel gate or peripheral side edges of a down-the-hole type steel gate and are compressed through a water stop pressing plate is generally adopted, contact surfaces of a gate embedded part and the water stop rubbers at a water seal position are subjected to surface roughness treatment, and the water stop rubbers cling to the embedded part under the action of water pressure to finish sealing in work. The water stopping structure has a good effect on sealing the periphery of a plane object, but is not suitable for sealing a tent type cofferdam with multi-dimensional panel splicing seams in a high water head environment.
Disclosure of Invention
The utility model provides a stagnant water structure that is used for fluffy formula cofferdam adjacent panel under water, aim at solve current stagnant water structure and can not satisfy the sealed problem between the fluffy formula cofferdam adjacent panel under the high waterhead environment.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
a stagnant water structure for between adjacent panel of fluffy cofferdam under water, which comprises a pane, surface welded channel-section steel links to each other with cofferdam steel truss spiro union under the panel, the channel-section steel sets up the edge at every panel, and adjacent panel links to each other through the bolt spiro union of wearing to establish on adjacent channel-section steel web, be provided with the stagnant water rubber banding between the adjacent channel-section steel web, the bolt sets up to two rows along panel concatenation seam direction, including the outer bolt that is close to channel rivers one side and the interior bolt that is close to cofferdam workspace one side, the stagnant water rubber banding is including being close to the outer stagnant water rubber banding that the outer bolt outside set up with be close to the interior stagnant water rubber banding that the interior bolt outside set up, form the seepage water passageway between outer stagnant water rubber banding and the interior.
An outer positioning block and an inner positioning block are arranged between the adjacent channel steel webs, the outer positioning block is arranged on the outer bolt in a penetrating mode, and the inner positioning block is arranged on the inner bolt in a penetrating mode.
The utility model provides a water stop structure used between adjacent panels of an underwater awning type cofferdam, wherein an inner water stop and an outer water stop are arranged between the adjacent panels, and a seepage water channel is formed between the two water stops; when the cofferdam is used, the outer water-stopping rubber strip is used for resisting most of channel flowing water pressure, a small amount of seepage water can be discharged to a designated position along the seepage water channel, and therefore the inner water-stopping rubber strip is located in an approximately non-pressure environment, and the sealing performance of the cofferdam is guaranteed.

Detailed Description
As shown in figure 3, the water stop structure for the underwater awning type cofferdam of the utility model comprises panels 1, channel steel 2 welded on the lower surface of the panels 1 is connected with the cofferdam steel truss in a screwed way, the channel steel 2 is arranged at the edge of each panel 1, and the adjacent panels 1 are connected by bolts penetrating through the webs of the adjacent channel steel 2, a water-stopping rubber strip is arranged between the webs of the adjacent channel steel 2, the bolts are arranged in two rows along the splicing seam direction of the panel 1 and comprise outer bolts 3 close to one side of the water flow of the channel and inner bolts 4 close to one side of the working area of the cofferdam, the water stopping rubber strip comprises an outer water stopping rubber strip 5 which is made of common rubber and is arranged close to the outer side of the outer bolt 3, and an inner water stopping rubber strip 6 which is arranged close to the outer side of the inner bolt 4 and is made of water-swelling rubber, wherein a water seepage channel 7 is formed between the outer water stopping rubber strip 5 and the inner water stopping rubber strip 6. In order to facilitate installation of the water-stop rubber strip, an outer positioning block 8 and an inner positioning block 9 are installed between webs of adjacent channel steel 2, wherein the outer positioning block 8 is arranged on the outer bolt 3 in a penetrating mode, and the inner positioning block 9 is arranged on the inner bolt 4 in a penetrating mode.
