Problems solved by technology

[0004] 1) The earth weir must not be excavated until the entire project is completed. Due to the limitation of the drainage channel by the river channel, the general circulation area is relatively small. The weir is flooded into the work area
Damage to civil works or equipment and related tools under construction, resulting in huge losses;
[0005] 2) The steel dam / hydraulic dam has problems in use and needs to be repaired or the daily maintenance is very difficult
Due to the high risk of launching operations and the fact that they are in water, many problems cannot be solved or cannot be completely solved
This makes the steel dam / hydraulic dam impossible to repair or can only solve surface problems, which seriously affects the service life of the equipment and even leads to unpredictable consequences

Embodiment Construction

[0014] The present invention will be further clarified below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0015] Such as figure 1 with figure 2 As shown, a large-scale river dam maintenance gate includes an earth weir 1 that has been built on both sides. The earth weir 1 is provided with a working area 2 for building the main dam; and at the upstream and downstream sides of the working area 2 Detecting door piles 3 are respectively provided, and corresponding door slots 4 are also provided on both sides of the detecting door piles 3 and the inner side walls of the soil weir 1 on both sides, and in the corresponding door slots 4 A sealed inspection gate 5 is inserted from top to bottom; and the inspection gate 5 is stacked...

Abstract

The invention discloses a large watercourse dam bulkhead gate. The large watercourse dam bulkhead gate comprises earth banks already constructed on the two sides; working areas for constructing a maingate dam are arranged in the earth banks; detection gate piles are correspondingly arranged on the upstream and the downstream places of the two outer sides of the working areas; corresponding gate slots are formed in the two sides of the detection gate piles and the inner side walls of the earth banks 1 on the two sides; and closed type bulkhead gates are inserted into the corresponding gate slots from top to bottom. Watercourse overcurrent in non-working areas are utilized effectively, and the working areas can be protected effectively during heavy rain or floods; the difficulties of a steel dam / hydraulic dam in later curing and maintenance are overcome, the curing danger and cost under raw water are reduced, and multiple projects which can not be maintained originally are optimized tobe maintainable projects; and the bulkhead gates of the large watercourse dam bulkhead gate are simple in structure, light in weight and convenient to operate and the cost is saved.

Description

Technical field [0001] The invention relates to a metal steel structure gate in hydraulic machinery, in particular to a large-scale river and dam maintenance gate. Background technique [0002] At present, large river steel dam gates are too wide and there is no maintenance door. Two earth weirs before and after the river are set up in the early stage of the project to enclose the work area, and at the same time, the diversion channel is excavated to bypass the work area to divert the water, and then work The stagnant water in the district is pumped dry. After the water in the work area is drained, the civil work of the dam will begin. After the civil construction is completed, the steel dam or hydraulic dam will be installed. After the steel dam can work normally, the earth weir will be excavated for water supply. [0003] The current working methods have the following problems: [0004] 1) The earth weir must not be excavated until the entire project is completed. Because the dr...
