[0002] In the waterproof and drainage construction design of high - speed railway tunnels, semi - circular drainage grooves need to be set on both sides of the bed of the high - speed railway tunnel to ensure the drainage effect of the bed in the railway tunnel. In the existing traditional construction technology, a φ100mm steel pipe is used to press the groove into shape manually after the filling and pouring are completed. Since the conventional method is all manually completed, the labor cost is relatively high, and the groove pressing has great randomness and low standard. During the groove pressing process, it is easy to cause inconsistent thickness of the protective layer of the groove wall, linear deviation, the elevation of the groove bottom and the slope of the flowing water surface not conforming to the design, and linear dislocation and bottom step of the groove are easily formed at the connection of the two - plate filled semi - circular drainage grooves. At the same time, since the concrete structure in the high - speed railway tunnel is not allowed to be repaired and can only be polished, it is very easy to affect the overall beauty and drainage function of the structure.

[0003] Therefore, when reserving the φ100mm semi - circular drainage grooves on both sides of the bed of the high - speed railway tunnel, what kind of reservation technology to adopt is a difficult problem that needs to be solved urgently at present. Content of the Utility Model

The semi - circular panel, the end plates and the top plate are integrally welded and fixed.

[0007] Preferably, U - shaped groove holes are arranged at both ends of the top plate, and a first long - strip bolt hole is arranged in the middle of the end plate.

[0008] Preferably, the water tank mold assemblies of two adjacent units are connected by bolts, and the bolts pass through the first long strip bolt holes and are fixedly connected to the end plates.

[0009] Preferably, reinforcing plates are arranged on the left and right sides of the fixed connection plate. The fixed connection plate is fixedly welded to the top plate through the reinforcing plates, and the reinforcing plates are arranged as right-angled triangles.

[0010] Preferably, second long strip bolt holes are arranged on the fixed connection plate.

[0027] Embodiment

[0028] As Figure 1 - Figure 2As shown in the figure, a structure of a reserved device for semi-circular drainage grooves on both sides of the ballast bed of a high-speed railway tunnel in the present utility model includes a water trough mold assembly 1, an inverted arch filling side mold 3, and a top connecting plate 2. A fixed connecting plate 11 is arranged on the water trough mold assembly 1, and the top connecting plate 2 is fixedly welded on the inverted arch filling side mold 3 to ensure that the top connecting plate 2 and the fixed connecting plate 11 are connected and fixed by bolts 5; as Figure 5 shown, wherein the fixed connecting plate 11 is processed from a steel plate with a thickness of 10 mm, with a total length of 215 mm and a total height of 95 mm. Among them, the long side has a length of 125 mm and a height of 60 mm, the short side has a length of 90 mm and a height of 95 mm, and it is in an inverted "L" shape lying flat. At a position 15 mm from the top and the end on the long side, a second long strip-shaped bolt hole 1101 composed of a semi-circle with a diameter of φ20 mm on both sides and a rectangle with a size of 20 mm * 65 mm in the middle is opened. The total length of the second long strip-shaped bolt hole 1101 is 85 mm, which is used for bolt connection with the top connecting plate 2 on the inverted arch filling side mold 3. At the same time, except for the two sides of the side where the fixed connecting plate 11 is welded to the water trough mold assembly 1 being right angles, the other corners are all arcs with a diameter of φ20 mm. Reinforcing plates 12 are arranged on the left and right sides of the fixed connecting plate 11, and the fixed connecting plate 11 is welded and fixed to the water trough mold assembly 1 through the reinforcing plates 12. The reinforcing plates 12 are processed from steel plates with a thickness of 6 mm into right-angled triangles with right-angled sides of 60 mm and 50 mm respectively. After the water trough mold assembly 1 and the top connecting plate 2 are connected and combined, the thickness of the groove wall protective layer of the semi-circular drainage groove 7 can be adjusted between 30 mm and 50 mm through the bolts 5 at the position of the second long strip-shaped bolt hole 1101 on the fixed connecting plate 11. After installation, the drainage groove reserved device is reserved and formed synchronously with the pouring of the filling concrete 4, effectively ensuring that the thickness of the groove wall protective layer and the cross-sectional dimensions of the semi-circular drainage groove 7 are consistent, and the bottom elevation and the flowing water slope of the groove both meet the drainage function requirements.

[0029] As Figure 3 shown, the three-dimensional model of the water trough mold assembly 1 is shown. One unit of the water trough mold assembly 1 includes a fixed connecting plate 11, a reinforcing plate 12, a top plate 13, an end plate 14, and a semi-circular panel 15. Two end plates 14 are respectively welded in the semi-circular grooves at both ends of the semi-circular panel 15, and the outer side surfaces of the end plates 14 are flush with the end surfaces at both ends of the semi-circular panel 15; the top plate 13 is welded in the groove at the top of the semi-circular panel 15, and the top surface of the top plate 13 is flush with the top surfaces of the pipe walls on both sides of the semi-circular panel 15. Both ends of the top plate 13 are closely adjacent to the end plates 14; as Figure 8 shown, the semi-circular panel 15 is processed from a steel pipe with an outer diameter of φ105 mm and a wall thickness of 7 mm, and the length of the steel pipe is 3 m, removing 1 / 2 of the cross-section; as Figure 7 shown, the end plate 14 is processed from a steel plate with a thickness of 10 mm into a semi-circle with a diameter of φ91 mm, and a first long strip-shaped bolt hole 1401 is horizontally opened in the middle of the semi-circle, which is used for the longitudinal bolt connection of each unit of the water trough mold assembly 1;Figure 6 As shown in the figure, the top plate 13 is processed from a steel plate with a thickness of 6 mm into a rectangle with a length of 298 cm and a width of 91 mm. At both ends of the top plate 13, a U-shaped slot hole 1301 composed of a semi-circle with a diameter of φ65 mm and a rectangle with a length of 73 mm and a width of 65 mm is opened respectively for the longitudinal connection and fixation of the water tank mold assembly 1. For example, Figure 4 As shown in the figure, the longitudinal connection between two adjacent water tank mold assemblies 1 is achieved by passing the M14 bolt 5 through the first long strip bolt hole 1401 of the end plate 14 of two adjacent unit water tank mold assemblies through the U-shaped slot holes 1301 reserved at both ends of the top plate 13 and tightening it with a nut 6, which ensures that there is no problem of misalignment at the joint of the semi-circular drainage trough 7, the line is smooth, the surface is flat, the joint is well-fitted, and the structure is beautiful.

[0030] Therefore, the present utility model adopts a semi-circular drainage trough reserved device on both sides of the high-speed rail tunnel bed with the above structure. During the use process, the drainage trough reserved device is reserved and formed synchronously with the pouring of the filling concrete. After the fixed connecting plate and the top connecting plate in the water tank mold assembly are connected and combined by bolts, the position of the bolt in the second long strip bolt hole of the fixed connecting plate can be adjusted so that the thickness of the groove wall protective layer of the semi-circular drainage trough can be adjusted between 30 mm and 50 mm. At the same time, by passing the bolt through the first long strip bolt hole of the end plate in two adjacent unit water tank mold assemblies and tightening it with a nut, the longitudinal connection of the water tank mold assembly can be realized, effectively ensuring that the thickness of the groove wall protective layer, the elevation of the groove bottom and the slope of the flowing water surface of the formed semi-circular drainage trough are consistent with the design, and the joints of the semi-circular drainage trough are well-fitted and there is no problem of misalignment at the joints, meeting the requirements of internal solidity, external beauty and drainage function.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
