Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a sluice side water-stop steel plate and a fixing method thereof. Background Art

[0002] The water-stop steel plate on the side of the sluice is a vital component of the sluice project. Its importance is mainly reflected in the following aspects: preventing leakage, ensuring water retaining function, maintaining structural stability, and improving the durability of the gate and extending its service life.

[0003] However, the current conventional construction method for the side waterstop steel plate of the sluice gate mostly adopts the method of secondary pouring of the pier wall, that is, first pouring half of the pier wall structure, reserving welded steel bars as a fixed reference; then welding and fixing the steel bars to the anchor bars on the back of the side waterstop steel plate, and then pouring secondary concrete to ensure the verticality and flatness of the side waterstop steel plate during installation.

[0004] However, the above method has shortcomings. For structures with smaller sluice pier wall thickness, manual entry into a confined space is required to perform welding operations. The secondary pouring method increases the amount of work and easily affects the molding quality. In order to solve the above problems and improve the installation efficiency and quality of the sluice side waterstop steel plate, we propose a sluice side waterstop steel plate and a fixing method thereof. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies mentioned in the above-mentioned background technology and to provide a sluice side water-stop steel plate and a fixing method thereof.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A side water stop steel plate for a sluice gate, comprising two side water stop plates with inner grooves on the inner sides, the two side water stop plates being arranged on the dam body and located at both ends of the gate body;

[0008] Pier wall reinforcement bars are provided at the connection surface between the dam body and the side water stop plate, and a plurality of channel steels for connection are provided between the side water stop plate and the pier wall reinforcement bars.

[0009] Preferably, the gate body is rotatably installed in the dam body through a hydraulic hoist, and the inner groove is in a fan-shaped structure coaxially arranged with respect to the gate body;

[0012] Preferably, the side water stop plate is made of stainless steel, and the channel steel and pier wall reinforcement are made of Q235B steel.

[0013] A method for fixing a water-stop steel plate on a sluice side, the fixing method specifically comprising:

[0014] Step 1: Install the formwork, assemble the steel bars, reserve the pier wall steel bars at the connection position of the side water stop plate of the dam body, and weld the fixed channel steel on the inner side of the side water stop plate;

[0015] Step 2: Use a hand chain hoist to hoist the side water stop plate, so that the channel steel fits the pier wall reinforcement, and temporarily fix the side water stop plate with reinforcement to prevent the plate from overturning;

[0016] Step 3: Set up a buckle frame between the two side water stop plates on the dam body, and adjust and maintain the vertical accuracy of the plate body by adjusting the horizontal steel support on the buckle frame to support it on the side water stop plate surface;

[0017] Step 4: Fully weld the stainless steel patch at the corresponding surface pipe end of the steel support and the side water stop plate, and spot weld the stainless steel patch and the side water stop plate to keep the side water stop plate fixed;

[0018] Step 5: After completing the above operations, cut the steel bars for temporary fixation, and then carry out the one-time pouring and forming construction of the dam pier wall concrete.

[0019] Preferably, a pillow pad is installed at the bottom end of the buckle frame.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

In addition, there is no need to weld the side water-stop steel plate to the steel bars of the dam body pier wall, and the steel support on the disc-buckle frame and the side water-stop steel plate are fixedly connected with stainless steel patches, which can avoid direct contact between the welded steel pipe and the stainless steel side water-stop plate, and avoid further damage caused by grinding and polishing after later cutting.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0032] See also Figure 1-6 The present invention describes the above technical solution in detail through the following embodiments:

[0033] The water stop steel plate on the side of the sluice gate in this embodiment is as follows Figure 1 As shown in the installation diagram, it is fixedly installed on the dam body 1 and located at both ends of the gate body 3.

[0034] Consider increasing the gate's rotation life to avoid direct contact with the concrete dam body and causing wear, such as Figure 2-Figure 4 In the structure shown, an inner groove 41 is provided on the inner side of the side water stop plate 4. In this embodiment, the gate body 3 is rotatably installed in the dam body 1 through the hydraulic hoist 2. The driving of the gate body 3 belongs to the prior art, so no further explanation is given.

[0035] The gate body 3 rotates along the shaft, so Figure 4 As shown, the inner groove 41 of this embodiment is in a fan-shaped structure coaxially arranged with respect to the gate body 3 , so that both ends of the gate body 3 can fit in the inner groove 41 and rotate in a limited position.

[0036] The focus of the above-mentioned structure during the construction process is how to efficiently install the side water stop plate 4 on the pier wall of the dam body 1. This embodiment creatively realizes one-time casting and molding, and the specific construction steps are: build the steel structure of the dam body 1, weld the channel steel 7 on the inside of the side water stop plate 4, and temporarily fix the channel steel 7 and the steel structure of the dam body 1 with steel bars to avoid welding and plate tipping.

[0037] The temporary fixed structure has poor fixation during the pouring process, so a buckle frame 5 is built between the two side water stop plates 4 through a support pad 6. The steel supports 51 horizontally arranged on the buckle frame 5 are adjusted to support the side water stop plates 4 on both sides and adjust the vertical accuracy of the plate body.

[0038] After the vertical precision is adjusted and fixed, stainless steel patches are welded between the steel support 51 and the side water stop plate 4, and spot welding is used on the side of the side water stop plate 4 to facilitate subsequent separation and cleaning of welding points; finally, the formwork is supported, and concrete can be poured directly, or the temporarily fixed steel structure can be removed. After the concrete is formed, the mold is demolded and the buckle frame 5 is removed, and the inner pier wall surface is polished smooth to complete the construction.

[0039] In order to obtain a good concrete fixing effect, the channel steel 7 is arranged as follows. Figure 6 The position relationship shown allows it to be immersed in the dam body 1 to a depth of 50 cm. If the depth is smaller, the side water stop plate 4 will fall off during the process of flipping the gate. In this embodiment, the side water stop plate 4 is made of 304 stainless steel, and the channel steel 7 and pier wall reinforcement are made of Q235B steel.
