Description

Technical Field

[0001] The invention relates to a flood prevention baffle device, in particular to a flood prevention baffle device used in a tunnel during flood season and a using method thereof. Background Art

[0002] In the first phase of a rail transit line project, the interval tunnel segments adopt a universal lining ring staggered assembly design. The lining ring has an outer diameter of Φ6.6m, an inner diameter of Φ5.9m, a thickness of 350mm, a lining design strength of C55, and a water-resistance grade of P10 (deep burial and ultra-deep burial P12).

[0003] The shield tunnel section of the first phase of the rail transit line project has four sections, a total of 3 communication channels, and 4 communication channels and pump stations. Flood control walls need to be set up at the tunnel entrance and on both sides of the communication channels, and water retaining dams need to be arranged on both sides of the communication channels before the construction of the communication channels for the construction of the communication channels.

[0004] This project has four sections and eight tunnels. At least 16 flood control retaining walls need to be built in this section. The production cycle of concrete flood control retaining walls is long. It takes 5 to 7 days from steel bar binding, template installation to concrete pouring and maintenance. After the production is completed, it cannot be moved. Before the tunnel is handed over, the flood control retaining wall needs to be chiseled out and restored to its original state. The project workload is relatively large.

[0005] Therefore, there is an urgent need for a reusable flood baffle device in the tunnel, which, in addition to meeting the water-blocking standard, must also have the characteristics of simple structure, easy installation, and the ability to change the installation position according to the construction situation and be reusable. Summary of the invention

[0006] The present invention provides a flood prevention baffle device that can be recycled in a tunnel and a method for using the device. The device is installed during the civil construction phase using a pre-buried chute of the permanent structure of the pipe segment to perform a water-blocking function during the construction phase, thereby preventing water accumulated in the end well during the flood season from flowing into the tunnel from the tunnel entrance and flooding the shield equipment, thereby ensuring the safe and stable operation of the equipment.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a flood baffle device that can be recyclably used in a tunnel, comprising: a flood control platform base, a socket-type water baffle, and an elastic rubber sealing pad. The flood control platform base is connected to the pre-embedded slide groove of the pipe segment through M12T-type bolts for fixing the flood control baffle device, and the socket-type water baffle is inserted into the flood control platform base slot of the flood control platform base; the flood control baffle device is tightly attached to the pipe segment through the flood control platform base and the bottom sealing pad of the socket-type water baffle, and sandbags are placed between the two socket-type baffles to achieve the water blocking function.

[0008] Furthermore, the flood control platform base is welded from three 3mm thick steel plates, the top surface is 800mm*880mm steel plate, the two sides are steel plates with an upper length of 880mm, a height of 459mm, and a bottom arc length of 997mm, and the inner steel plate is 800mm*459mm steel plate. Grooves are set between the steel plates, and the width of the grooves is 40mm.

[0009] Furthermore, 9 φ16mm steel bars are welded in the middle of the flood control platform base for reinforcement, and 250mm long and 80mm wide steel plates are welded on both sides, and angle iron diagonal braces are used for reinforcement.

[0010] Furthermore, after the welding of the flood control platform base is completed, a 5mm thick waterproof sealing gasket is pasted on the bottom to prevent the occurrence of water leakage channels.

[0011] Furthermore, the socket-type water retaining plate is welded from two 3 mm thick steel plates, and No. 4 channel steel is welded at both ends of the steel plates for connection with the slot of the flood control platform base.

[0012] Furthermore, a 5mm thick waterproof sealing gasket is pasted on the contact surface between the bottom of the socket-type water retaining plate and the pipe segment, and the contact surface between the channel steel and the slot of the flood control platform base to prevent the occurrence of water leakage channels.

[0013] A method for using a recyclable flood baffle device in a tunnel comprises the following steps: firstly, connecting a flood control platform base with a pre-buried chute of a pipe segment with M12T-type bolts at both ends of a tunnel opening, fixing the device on a lining pipe segment, then inserting a socket-type water baffle into a slot of the flood control platform base, and finally placing a sandbag between two socket-type water baffles to achieve its water blocking function.

[0014] Furthermore, after use, pull out the socket-type water retaining plate, unscrew the M12T-bolts, remove the flood control platform base, and replace the waterproof sealing gasket before the next use to prepare for the next use.

[0015] The beneficial effects of the present invention are:

[0016] The present invention is a flood-proof baffle device that can be recycled in a tunnel and a method for using it. The device consists of a flood-proof platform base, a socket-type water baffle, an M12T-type bolt, a φ16mm steel bar connecting rib, an elastic rubber sealing pad, and an angle iron diagonal brace. By improving the flood-proof baffle at the tunnel entrance, the flood-proof baffle can be quickly moved and opened and closed, and the water-blocking function of the flood-proof baffle is completed, so that the accumulated water in the end well during the flood season is prevented from flowing into the tunnel from the tunnel entrance and flooding the shield equipment, thereby ensuring the safe and stable operation of the equipment. The device can be reused, which saves costs, and has a simple structure, ingenious design, low manufacturing cost, and easy installation. By adjusting its shape and size, it can be widely used in various types of tunnel waterproofing construction, and has great applicability and economic prospects. BRIEF DESCRIPTION OF THE DRAWINGS

It is easy to install, recyclable, and can be widely used in various tunnel waterproofing constructions by adjusting its shape and size. The flood control baffle device inserts the spigot-type water baffle 3 into the flood control platform base 1 through the flood control platform base slot 2. The flood control platform base 1 and the spigot-type water baffle 3 can be adjusted according to the tunnel structure, and the spigot-type water baffle can be removed during daily construction without affecting the shield construction.

[0023] The flood control platform base 1 is welded by three 3mm thick steel plates, the top surface is 800mm*880mm steel plate, the two sides are steel plates with an upper length of 880mm, a height of 459mm, and a bottom arc length of 997mm, and the inner steel plate is 800mm*459mm steel plate. Grooves are set between the steel plates, and the width of the grooves is about 40mm. Nine φ16mm steel bars 5 are welded in the middle of the base for reinforcement. A 250mm long and 80mm wide steel plate is welded on both sides of the flood control platform base 1 (a bolt hole is set at the center of the steel plate 20cm for connecting the lining segments), and angle iron diagonal braces 7 are used for reinforcement. After the flood control platform base 1 is welded, a 5mm thick elastic rubber sealing pad 6 is pasted on the bottom of the base to prevent the occurrence of leakage channels.

No. 4 channel steel is welded at both ends of the steel plate to connect with the flood control platform base slot 2. A 5mm thick elastic rubber sealing pad 6 is pasted on the contact surface between the bottom of the spigot-and-socket water retaining plate 3 and the lining segment 8, and the contact surface between the channel steel and the flood control platform base slot 2 to prevent the occurrence of water leakage channels.

[0025] At both ends of the tunnel entrance, the flood control platform base 1 is connected to the pre-buried slide groove of the pipe segment with M12 T-bolts 4 and fixed on the lining pipe segment 8. Then, the socket-type water retaining plate 3 is inserted into the slot 2 of the flood control platform base. Finally, sandbags 9 are placed between the two socket-type water retaining plates 3 to achieve its water-blocking function.
