DETAILED DESCRIPTION

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This embodiment provides a flood prevention structure for the end of a U-shaped channel in a subway section, such as... Figures 1 to 5 As shown, the structure includes a concrete end wall 1, a concrete column 2, a concrete retaining wall 3, a detachable baffle assembly, an adjustable irregular-shaped baffle assembly, and a rotatable baffle assembly 6. The concrete end wall 1, concrete column 2, and concrete retaining wall 3 shall not encroach on the traffic clearance and shall be used as permanent structures. The two concrete end walls 1 are respectively set on the inner side walls of the two sides of the U-shaped channel, arranged symmetrically, and respectively connected to the two side walls of the U-shaped channel. The concrete column 2 is set on the bottom plate of the U-shaped channel and is located in the middle of the U-shaped channel. The concrete retaining wall 3 is set on the bottom plate of the U-shaped channel, and its two ends are respectively connected to the concrete end wall 1 and the concrete column 2.

[0031] Both the concrete end wall 1 and the concrete column 2 are provided with grooves. The detachable baffle assembly can be installed between the concrete end wall 1 and the concrete column 2 through the grooves. The detachable baffle assembly includes several detachable baffles 4 with waterproof strips at the bottom. Several detachable baffles 4 are vertically assembled. After the detachable baffle assembly is installed between the concrete end wall 1 and the concrete column 2, its bottom is attached to the top of the concrete retaining wall 3.

[0032] The removable baffle 4 is made of aluminum alloy, and the height of each removable baffle 4 is no more than 20cm. The sealing strip at the bottom of the lowest removable baffle 4 in the removable baffle group is no less than 30mm thick to prevent the rail 8 from conducting electricity through the removable baffle 4.

[0033] Several wire-passing holes are reserved on the concrete end wall 1. The rubber sheet 7 is fixed to the outer wall of the concrete end wall 1 and covers the wire-passing holes. The rubber sheet 7 has wire-passing openings, and the wire-passing direction is from the inside to the outside. The rubber sheet 7 can ensure the waterproof effect at the wire-passing holes.

[0034] The top of the concrete retaining wall 3 is not higher than the rail surface level, and the top of the concrete retaining wall 3 is provided with a groove 31 for laying the steel rail 8. An adjustable special-shaped baffle set is installed on the side wall of the concrete retaining wall 3, and the adjustable special-shaped baffle set includes two adjustable special-shaped baffles 5. The two adjustable special-shaped baffles 5 are respectively installed on both sides of the groove 31. The shape of the adjustable special-shaped baffle 5 close to the steel rail 8 is consistent with the shape of the steel rail 8. Two long strip-shaped bolt holes 51 are horizontally arranged on the adjustable special-shaped baffle 5. Bolts 52 are pre-buried on the side wall of the concrete retaining wall 3. The adjustable special-shaped baffle 5 can be adjusted left and right through the long strip-shaped bolt hole 51, and is fixed through the bolt 52 passing through the long strip-shaped bolt hole 51. The gap between the steel rail 8 and the groove 31 in which the steel rail 8 is located can be closed by adjusting the adjustable special-shaped baffle set.

[0035] The adjustable special-shaped baffle 5 is made of 20mm thick galvanized steel plate. The edge of the adjustable special-shaped baffle 5 close to the steel rail 8 is provided with a waterproof rubber strip. The adjustable special-shaped baffle set is installed on the inner side wall or the outer side wall of the concrete retaining wall 3, as shown in Figure 1

[0036] The side wall of the concrete retaining wall 3 is provided with a drainage hole 9 for normal operation drainage. The rotatable baffle set 6 includes a fixed plate 61 and a turning plate 62. The fixed plate 61 is fixedly installed above the drainage hole 9 on the outer side wall of the concrete retaining wall 3. The bottom of the fixed plate 61 is rotationally connected with the turning plate 62. The drainage hole 9 can be closed by turning the turning plate 62. The edge of the turning plate 62 is provided with a pull ring 63, which facilitates turning the turning plate 62. The fixed plate 61 and the turning plate 62 are made of 20mm thick galvanized steel plate.

[0037] When there is no need for flood prevention in daily life, the adjustable special-shaped baffles 5 are adjusted to the two sides of the groove 31 to ensure that the adjustable special-shaped baffles 5 do not intrude into the running limit; and the turning plate 62 of the rotatable baffle set 6 is turned up to keep the drainage hole 9 in an open state.

[0038] When flood prevention is needed, the adjustable special-shaped baffles 5 are moved, the turning plate 61 of the rotatable baffle set 6 is turned, and the detachable baffle 4 is installed. Specifically, as shown in Figures 3 to 5 , the nuts are loosened, and the adjustable special-shaped baffles 5 are moved towards the steel rail 8. When the adjustable special-shaped baffles 5 contact the steel rail 8, the two adjustable special-shaped baffles 5 contact below the steel rail 8. Then the bolts 52 are tightened to close the gaps on both sides and below the steel rail 8. The turning plate 62 of the rotatable baffle set 6 is turned so that the turning plate 62 contacts the bottom surface 10 of the drainage ditch on the ballast layer 11 to close the drainage hole 9. The detachable baffle 4 is quickly installed to close between the concrete end wall 1 and the concrete column 2.

[0039] ​After the flood prevention is completed, the detachable baffle 4 is detached, the adjustable special-shaped baffle 5 and the flap 62 of the rotatable baffle group 6 are restored to the original position. Specifically, as shown in Figure 2 、 Figure 5 the adjustable special-shaped baffle 5 is moved to the sides of the groove 31 to avoid the track position and then fixed by the bolt 52; the flap 62 of the rotatable baffle group 6 is turned to an angle less than 90° with the concrete retaining wall 3 by the pull ring 63, and the drainage hole 9 is opened.

[0040] As can be seen from the above technical solutions, the flood prevention structure of the end of the U-shaped groove of the subway section provided by the embodiment can quickly realize the closure of the end of the U-shaped groove, is convenient to operate, saves time and effort, has strong popularization value; the concrete structure and the baffle group are combined and arranged in a clever manner, the structure is reliable, the safety is strong, the sealing performance is good, has good flood prevention effect, ensures the safety of subway operation, and has strong market competitiveness.
