[0029] The sliding unit is arranged on the main rib 7 of the wall formwork and is slidably connected to the main rib 7 of the wall formwork; the outer side of the sliding unit is connected to the hopper body 1 through the supporting legs 2 so that the hopper body 1 can move along the main rib 7 of the wall formwork.
[0030] Among them, preferably, four legs 2 are provided, two legs 2 form a group, and the two groups of legs 2 are relatively arranged on the two outer walls of the hopper body 1 along the width direction of the wall formwork 8. The two legs 2 in each group are longitudinally arranged to connect the hopper body 1 with the wall formwork 8, and the two legs 2 in each group are arranged parallel to each other, and the connection points of the four legs 2 and the hopper body 1, and the connection points of the four legs 2 and the wall formwork 8 are all located on the same horizontal line.
[0031] Through the above technical scheme, concrete is introduced into the feed port on the wall formwork 8 where it needs to be poured through the hopper body 1, so as to pour the drainage ditch concrete; the sliding unit is arranged on the main rib 7 of the wall formwork, and is slidably connected with the main rib 7 of the wall formwork; the outer side of the sliding unit is connected with the support leg 2 at an adjustable distance, which can realize the adjustment of the distance between the sliding unit and the support leg 2, and enable the hopper body 1 to move along the main rib 7 of the wall formwork.
[0032] In this embodiment, the hopper body 1 is a hollow structure; an inlet 5 is provided at the top of the hopper body 1; two outlets 6 are provided at the bottom of the hopper body 1; an inverted V-shaped guide plate 9 is provided inside the hopper body 1, and the guide plate 9 is provided corresponding to the inlet 5 to guide the concrete entering from the inlet 5 to the two outlets 6; the two outlets 6 are provided corresponding to the inlets at both ends of the wall formwork in the width direction.
[0033] The feed inlet 5 at the top of the hopper body 1 is preferably a circular feed inlet 5 with a diameter of 30 cm.
[0034] Among them, the two ends of the guide plate 9 along the length direction of the wall template 8 are fixedly connected to the main body of the hopper body 1 respectively; the two ends of the guide plate 9 along the width direction of the wall template 8 are connected to the bottom of the hopper body 1; the two discharge ports 6 are symmetrically arranged at the two ends of the guide plate 9 along the width direction of the wall template 8 with respect to the feed port 5; the discharge ports 6 extend along the length direction of the wall template 8.
[0035] Through the above technical scheme, concrete enters the hopper body 1 from the feed port 5, and the inverted V-shaped guide plate 9 diverts the concrete entering the hopper body 1, dividing the concrete into two flows, one of which flows from the left discharge port 6 at the bottom of the hopper body 1 to the feed port at one end in the width direction of the wall formwork 8, and the other flows from the right discharge port 6 at the bottom of the hopper body 1 to the feed port at the other end in the width direction of the wall formwork 8, which can ensure that all the concrete falls into the wall formwork 8, reducing material waste and saving costs.
[0036] In this embodiment, the sliding unit includes a connecting plate 401 and two pulleys 3; the two pulleys 3 are longitudinally clamped on the main rib 7 of the wall formwork; the connecting plate 401 is a U-shaped structure, and the two ends of the connecting plate 401 are respectively connected to the two pulleys 3; the outer wall of the connecting plate 401 is connected to the telescopic unit 4.

[0038] Through the above technical scheme, the two pulleys 3 are respectively arranged at the two ends of the longitudinal extension direction of the main rib 7 of the wall formwork, so that the hopper body 1 can slide freely on the main rib 7 of the wall formwork along the length direction of the wall formwork 8; during pouring, when the pouring of a certain section on the wall formwork 8 is completed, the hopper body 1 is pushed to slide to the place where the next section of the wall formwork 8 needs to be poured. There is no need to disassemble the tools each time for pouring, and it can be directly slid on the main rib 7 of the wall formwork, which greatly saves pouring time, saves manpower, and improves work efficiency.
[0039] In this embodiment, the supporting leg 2 and the connecting plate 402 are connected at an adjustable distance via a telescopic unit to adjust the distance between the supporting leg 2 and the connecting plate 402 .

After the gap between the upper and lower pulleys 3 is aligned with the main rib of the template, the length of the telescopic rod 402 is adjusted and tightened to ensure that the main rib of the template is located between the upper and lower pulleys 3. Finally, the position of the telescopic rod 402 is fixed by a pin.
[0045] In this embodiment, the legs 2 are made of square steel of 30 mm×30 mm.
[0046] In this embodiment, the wall thickness of the hopper body 1 is 1.5 mm.

[0048] Through the above technical scheme, the hopper body 1 is manufactured according to the thickness and spacing of the drainage ditch side walls in the construction drawing, the width of the discharge port 6 and the width of the inverted V-shaped material guide plate 9 are determined, and after the telescopic rod 402, the connecting plate 401 and the pulley 3 are assembled, one end of the leg 2 is welded to the hopper body 1, and the other end of the leg 2 is connected to the telescopic rod 402.
[0049] The working principle of the railway concrete drainage ditch pouring auxiliary device provided by the utility model is as follows:
[0050] First, after the railway concrete drainage ditch pouring auxiliary device is manufactured, the staff will lift the railway concrete drainage ditch pouring auxiliary device to the wall formwork 8 installation area, adjust the telescopic rod 402 to the maximum length, so that the width between the two sets of legs 2 set opposite to each other is the maximum width, and after the gap between the upper and lower pulleys 3 is aligned with the main rib of the template, adjust the length of the telescopic rod 402 and tighten it to ensure that the main rib 7 of the wall template is located between the upper and lower pulleys 3, and finally fix the position of the telescopic rod 402 at this time by a latch, so that the hopper body 1 can slide freely on the wall formwork 8 through the pulley 3;
[0051] Secondly, pour concrete through the inlet 5, and pour the wall formwork 8 on both sides through the outlet 6 at the same time. When pouring to the appropriate position, the staff pushes the railway concrete drainage ditch pouring auxiliary device along the main rib 7 of the wall formwork 8 on the wall formwork 8 to the next position for pouring;
[0052] Finally, after repeating the above steps until all the construction is completed, the railway concrete drainage ditch pouring auxiliary device is removed by adjusting the telescopic rod 402, and it is washed clean and stored in a warehouse for recycling.
