Description

Technical Field

[0001] The present invention belongs to the field of water conservancy project construction, and more specifically, particularly relates to a spliced ​​water retaining device and an assembling method for water conservancy project construction. Background Art

[0002] Water retaining in river channel water conservancy construction is a method of intercepting water flow by building specific hydraulic structures inside the river channel to prevent water from invading the river channel construction site, thereby ensuring a dry and clean construction environment inside the construction site and ensuring normal construction operations inside the river channel. At present, the traditional water retaining and interception measures for water conservancy construction inside the river channel usually use a large number of sandbags to pile up and build a retaining wall at both ends of the construction river section, and then use a pump to drain the river water between the two groups of retaining walls. In the actual construction process, in order to stabilize the stacked sandbags, a large amount of sand and soil is required to form a supporting earth wall, and the sandbags also need to be carried and piled up by many people. It can be seen that the water retaining method using sandbags is large in construction volume and consumes more construction materials. In addition, the retaining wall formed by sandbags cannot be dismantled as a whole at one time during the later demolition process. The demolition process also requires many people to transport multiple groups of sandbags to dismantle the retaining wall, thereby reducing the efficiency of water conservancy construction and prolonging the construction progress of the river channel.

[0012] The assembly method of the spliced ​​water retaining device for water conservancy project construction comprises the following steps:

[0013] S1: Place the fixed support plate and the casing on the left and right walls of the river channel respectively, and fit the ear plates of the fixed support plate and the ear plates of the casing on the left and right walls of the river channel respectively. Then insert rivets into the ear plate through holes of the fixed support plate and the ear plate through holes of the casing, and use a hammer to drive the rivets into the left and right walls of the river channel. At this time, the sealing gaskets bonded to the fixed support plate and the casing are tightly fitted on the left and right walls of the river channel respectively.

[0014] S2: The convex strip of the baffle shell of the first baffle device is inserted into the groove of the fixed support plate by pulling the lifting ring with a crane, and the convex strip of the baffle shell of the second baffle device is inserted into the opening groove of the baffle shell of the first baffle device. When the two baffle shells are spliced ​​and inserted into each other, the inclined surface structure of the lower convex block of the lock tongue plate of the second baffle device is pressed and contacted with the top of the opening groove of the baffle shell of the first baffle device, and the convex block of the lock tongue plate is squeezed into the through groove of the convex strip of the baffle shell of the second baffle device by the inner side wall of the opening groove of the baffle shell of the first baffle device. The convex strip of the baffle shell of the device continues to be inserted downward along the opening groove of the baffle shell of the first group of baffle devices. When the lock tongue plate convex block of the second group of baffle devices is opposite to the rectangular groove of the baffle shell of the first group of baffle devices, the return spring drives the lock plate to push the two groups of lock tongue plates along the support rod through elastic force. The two groups of lock tongue plates move apart in opposite directions along the guide rod. The lock tongue plate convex block of the second group of baffle devices extends into the rectangular groove of the baffle shell of the first group of baffle devices for locking, and then the remaining baffle shells are spliced ​​in sequence according to the width of the river channel in the above manner.

[0015] S3: When the last set of baffle shells is spliced, the last set of baffle shells is close to the groove structure of the casing, and the handrail turntable is manually rotated.

The two sets of sliders push the two sets of connecting rods to flip synchronously, and the connecting rods drive the pressure plate to extend out of the through groove of the casing until the pressure plate is inserted into the open groove of the last set of baffle shells, completing the assembly of the spliced ​​water retaining device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the convex plate inclined surface structure of the lock plate is pushed by the elastic force of the return spring to squeeze the two groups of lock tongue plates, so that the convex block of the lock tongue plate extends out of the through groove of the convex strip of the baffle shell and penetrates into the rectangular groove of the inner wall of the opening groove of the other group of baffle shells, thereby realizing the rapid plug-in locking work between the two groups of baffle shells. Multiple groups of baffle shells are spliced ​​together to form a river retaining wall. When dismantling, the multiple groups of baffle shells are synchronously and integrally dismantled by a crane through pulling the lifting ring, replacing the traditional retaining wall construction method of stacking sandbags and the retaining wall dismantling method of transporting multiple groups of sandbags separately, thereby improving the construction and dismantling efficiency of the retaining wall, reducing the construction volume of the river retaining wall, and improving the efficiency of river water conservancy construction.

[0018] 2. In the present invention, the forward threaded end and the reverse threaded end of the bidirectional threaded rod in the clamping device are respectively formed in the threaded through holes of the two groups of sliders to operate the threaded engagement transmission mechanism, so that the two groups of sliders drive the pressure plate to extend out of the long through groove of the casing through the connecting rod hinged on the rear side, and the pressure plate cooperates with the fixed support plate to press the joints of the rubber gaskets between the multiple groups of baffle shells, thereby improving the anti-water seepage function of the baffle shell splicing position, and ensuring that the baffle shell can stably seal and block water at the river construction site.
