The damaged part of the water engineering of the water delivery channel can be directly maintained, and the damage repair of the underwater engineering generally adopts a water-stopping repair method; the water-stopping repairing mode takes a long time, and the water delivery capacity of the channel is seriously influenced, so that the benefit of the water delivery channel cannot be fully exerted.
The method for repairing the damage of the underwater engineering of the water delivery channel which cannot stop water generally adopts a method of arranging an earth-rock cofferdam, and the method utilizes excavation waste slag and filling of the earth-rock cofferdam to isolate and repair the area, thereby creating conditions for subsequent construction and having extremely wide application. However, the earth-rock cofferdam has the characteristics of large structural section, long construction period, low efficiency and great influence on the original channel structure, particularly on the water delivery capacity of the channel. How quick, convenient setting one kind to the channel section overflow influence less enclose the fender, seal channel engineering damage area, for the creation condition of restoration construction, it is the problem that a ratio is difficult to solve to take into account the channel simultaneously and overflow.
Disclosure of Invention
The invention aims to provide an enclosure structure suitable for non-water-stop repair of a large-scale water delivery channel.
In order to achieve the purpose, the invention adopts the following technical scheme:
The invention relates to an enclosure structure suitable for non-water-cut-off repair of a large-scale water delivery channel, which is formed by connecting a plurality of unit enclosures with the same structure through bolts; the unit enclosure comprises a base, the base is composed of three longitudinal supports and a plurality of transverse supports welded to the three longitudinal supports at intervals, and rubber cushion pads are mounted on the lower surfaces of the longitudinal supports and the transverse supports; the cross part of each transverse support and the longitudinal support positioned in the middle position is upwards fixedly connected with an inserting groove, and a flow baffle plate is inserted between the two inserting grooves with opposite notches; the two sides of each slot are respectively provided with an inclined strut, the upper end of each inclined strut is connected with the upper part of the corresponding slot, and the lower end of each inclined strut is connected with the transverse strut positioned at the middle position and corresponding to the two sides of the longitudinal strut.
And the adjacent slots are respectively connected with a tie rod through bolts.
The number of the cross bars of the cross support is four.
The plate surface of the flow baffle is welded with a transverse reinforcing rib and a vertical reinforcing rib.
The lower end of each inclined strut is connected with the corresponding transverse strut through a steel plate and a bolt respectively, and the upper end of each inclined strut is connected with the upper part of the corresponding slot through a steel plate and a bolt respectively; the lower end of each slot is connected with the longitudinal support positioned in the middle through a steel plate and a bolt.
the advantages of the invention are embodied in the following aspects:
1. Compared with the conventional earth-rock cofferdam, the cofferdam has the characteristics of convenience in installation, simplicity in operation and easiness in disassembly, and saves a large amount of time for engineering restoration.
2. The structure section is little, and weight is lighter relatively, and is little to channel structure and flow capacity that overflows influence.
3. By adopting the unit structure, the number of units can be flexibly and flexibly adjusted according to the damaged area, and the angle of the slot can be adjusted according to the slope ratio of the side slopes of different channels, so that the method is suitable for repairing the channels with different characteristics.
4. By adopting a modularized and assembled structure, most of the combined work is carried out on the shore, the installation efficiency is high, the repeated utilization is realized, and the economic benefit is higher.
5. The integral enclosure can relatively isolate the construction area from the water body of the channel, reduce the water quality pollution of the channel in the construction process, ensure the water delivery safety of the channel, reduce the flow velocity of the operation area and improve the working efficiency.
