Description

Technical Field

[0001] The utility model relates to the technical field of tunnel waterproof and drainage construction, in particular to a concave die tooling for the outlet of a drainage blind pipe in a high-speed railway tunnel. Background Technique

[0002] During the waterproof and drainage construction of high-speed railway tunnels, at the joint of the drainage blind pipe nozzle at the small side wall, due to the lack of special tooling for fixing and protecting, problems such as displacement and deformation of the drainage blind pipe nozzle, blockage of the pipe by concrete during the concrete pouring and vibration processes, and easy damage after form removal are likely to occur. In the past, the drainage blind pipe nozzle was drilled at the arc-shaped formwork of the inverted arch small side wall corresponding to the designed position, and the blind pipe was extended a certain length through the hole. The gap between the blind pipe and the hole periphery was sealed with geotextile or colored strip cloth to prevent concrete leakage. However, if the reserved length of the drainage blind pipe is insufficient, it is easy for the blind pipe to be detached from the hole under the impact of concrete pouring during the concrete pouring process, resulting in displacement of the blind pipe nozzle and blockage of the pipe by concrete. It is difficult to find after form removal and not easy to connect during the construction of the drainage channel and cable trough. When the reserved length is sufficient, the nozzle is easily squeezed and deformed under the impact force of the concrete. At the same time, when the concrete is demolded after pouring, a series of construction problems such as damage to the drainage blind pipe nozzle, poor appearance quality of the concrete around the nozzle, and easy pouring of geotextile or colored strip cloth into the concrete are likely to occur.

[0003] Therefore, when constructing the waterproof and drainage of high-speed railway tunnels, what kind of fixing tooling can be used for the drainage blind pipe nozzle at the small side wall to achieve accurate position, no displacement, effective protection, high efficiency, reliability, recyclability, and easy connection during the construction of the drainage channel and cable trough is a difficult problem that needs to be solved urgently. Summary of the Invention

[0004] The purpose of the utility model is to provide a concave die tooling for the outlet of a drainage blind pipe in a high-speed railway tunnel, which is convenient to install, accurate in positioning, can prevent the displacement of the blind pipe nozzle during construction, plays an effective protective role, is convenient to disassemble, safe and reliable, recyclable, and convenient to connect during the construction of the drainage channel and cable trough, and has considerable overall work efficiency.

[0005] To achieve the above purpose, the utility model provides a concave die tooling for the outlet of a drainage blind pipe in a high-speed railway tunnel, including a concave die tooling bottom plate.

The concave die tooling bottom plate is connected to the steel pipe and the concave die tooling side plates by welding. The concave die tooling side plates are all connected to a frame, and handles are symmetrically connected to the frame. The frame is connected to the concave die tooling side plates and the handles by welding.

[0006] Preferably, the steel pipe is cut obliquely from a seamless steel pipe with an outer diameter of Φ133mm and a wall thickness of 4mm. The angle of the oblique cutting surface is 42.68°, the length of the oblique cutting surface is 181mm, and the length of the steel pipe wall is 48mm.

[0007] Preferably, an oval through-hole corresponding to the steel pipe is provided on the bottom plate of the female die tooling.

[0008] Preferably, the side plate of the female die tooling is of a trapezoidal structure with a thickness of 5 mm. After the bottom plate of the female die tooling is welded to the four side plates of the female die tooling, it forms a frustum of a pyramid structure.

[0022] Embodiment 1

[0023] As Figures 1 to 6 shown, the present utility model provides a female die tooling for the outlet of the drainage blind pipe of a high-speed railway tunnel, which includes a female die tooling bottom plate 1. The female die tooling bottom plate 1 is processed from a 5-mm steel plate and has a square size of 200 mm. The center of the female die tooling bottom plate 1 is connected to a steel pipe 4, and the female die tooling bottom plate 1 provides support for the steel pipe 4. An oval through hole corresponding to the steel pipe 4 is provided on the female die tooling bottom plate 1. The size of the oval through hole is 160 mm for the major axis and 120 mm for the minor axis. The female die tooling bottom plate 1 and the steel pipe 4 are connected by welding. The steel pipe 4 is cut obliquely from a seamless steel pipe with an outer diameter of Φ133 mm and a wall thickness of 4 mm. The combined flowing water slope required for the steel pipe 4 is 2%, and the diameters are cut into an oblique cross-section at an oblique intersection angle to meet the drainage blind pipes 8 with diameters of Φ80 mm and Φ100 mm. The oblique section angle is 42.68°, the length of the oblique section is 181 mm, and the length of the steel pipe 4 wall is 48 mm.

[0024] The periphery of the female die tooling bottom plate 1 is connected to the female die tooling side plates 2, and both the female die tooling bottom plate 1 and the female die tooling side plates 2 are connected by welding. The female die tooling side plates 2 are trapezoidal structures with a thickness of 5 mm, an upper base length of 200 mm, a lower base length of 350 mm, and a height of 83 mm. After the female die tooling bottom plate 1 and the four female die tooling side plates 2 are welded, it is a frustum of a pyramid structure.

[0025] The side plates 2 of the concave die tooling are all connected to the frame 3, and the frame 3 is connected to the bottom plate 1 of the concave die tooling through the side plates 2 of the concave die tooling to form the concave die tooling. Handles 5 are symmetrically connected to the middle of the wide sides on both sides of the frame 3, which is convenient for moving the assembled concave die tooling. The frame 3 is connected to the side plates 2 of the concave die tooling and the handles 5 by welding. The frame 3 is made of a 5-mm steel plate. First, a square steel plate with a length of 470 mm and a width of 390 mm is processed, and then a square hole with a side length of 350 mm is opened in the middle. Two U-shaped grooves are provided on both sides of the frame 3 with a larger width. The distance between the two U-shaped grooves on one side is 200 mm. The U-shaped groove is composed of a semicircle with a diameter of Φ20 mm and a rectangle with a length of 30 mm and a width of 20 mm. The center of the semicircle is at the horizontal center point of the wide side. The handle 5 is a U-shaped handle made of HPB235 steel bar with a diameter of Φ10 mm. The long side (outer spacing) is 110 mm, and the short side (outer spacing) is 60 mm.

[0026] When using a concave die tooling for the outlet of a drainage blind pipe in a high-speed railway tunnel provided by the present utility model, the pipe head of the installed drainage blind pipe 8 with a diameter of Φ80 mm or Φ100 mm is passed through the steel pipe 4 inside the concave die tooling, and then the assembled concave die tooling is installed on the inverted arch small side wall arc template corresponding to the designed position of the drainage blind pipe 8 pipe orifice. A 350-mm square hole consistent with the bottom size of the quadrangular frustum of the concave die tooling is opened on the inverted arch small side wall arc template. Two M16 full-threaded screws 6 are welded at positions 30 mm away from the hole edge on both sides of the hole along the line and with a side length azimuth in the middle and a spacing of 200 mm. On both sides, M16 nuts 7 are tightened and fixed with the M16 full-threaded screws 6 on both sides of the square hole. After the concrete is poured and completed, the nuts 7 are unscrewed and the concave die tooling is taken out to complete the fixation, positioning and protection of the drainage blind pipe 8 pipe orifice.

[0027] Therefore, the present utility model adopts the above-mentioned concave die tooling for the outlet of a drainage blind pipe in a high-speed railway tunnel, which has the advantages of convenient installation, accurate positioning, effective protection against non-deviation of the blind pipe orifice during construction, easy disassembly, safety and reliability, recyclability, and convenient connection during the construction of the drainage ditch and cable trench, and the overall work efficiency is considerable.
