[0002] The thermal power generation industry, coal washing and coal transportation industries must use coal transport trestles when transporting coal. The coal transport trestles will generate a lot of dust and dirt during use, so the coal transport trestles need to be washed with water frequently.
[0003] The coal conveyor trestle consists of two parts: a high-end coal conveyor trestle and a low-end coal conveyor trestle. In order to avoid damage to the bridge body of the coal conveyor trestle due to thermal expansion and contraction, an expansion joint is usually arranged between the two parts, and the expansion joint is waterproofed.
[0004] The waterproof structure of the existing coal handling trestle expansion joint is as follows Figure 1 As shown, the high-end coal conveying trestle and the low-end coal conveying trestle are on a flat inclined plane, a waterstop is laid on the expansion joint, and then covered with a steel structure cover plate, the steel structure cover plate and the waterstop are fixed to the trestle deck by fasteners, and the part of the trestle deck other than the steel structure cover plate is the building surface layer (the building surface layer is poured later, and the fastening parts of the steel structure cover plate and the waterstop are poured together during pouring).
[0005] Although the waterproof structure of the expansion joint of the existing coal conveyor trestle is provided with a water stop for waterproofing, the water stop is easy to loosen and leak under long-term operation conditions, and the waterproof effect is poor. Black coal slurry often leaks, causing the factory environment to be polluted. Therefore, designing a waterproof structure for the expansion joint of the sloped coal conveyor trestle is a technical problem that people in this field need to solve urgently. Utility Model Content
[0006] In order to solve the above-mentioned technical problems, the utility model provides a waterproof structure for the expansion joint of a sloped coal conveying trestle. On the basis of waterproofing with a waterstop belt, the connection part between the high-end coal conveying trestle and the low-end coal conveying trestle is set as a stepped structure in which the connection end of the high-end coal conveying trestle is higher than the connection end of the low-end coal conveying trestle, and a part of space is reserved in the up and down and left and right directions. Gravity waterproofing is performed by relying on the structural shape, and an upwardly protruding waterproof slope is set on the surface of the low-end coal conveying trestle below the connection end of the high-end coal conveying trestle, so as to further prevent sewage from flowing into the expansion joint, thereby completely solving the problem of water leakage in the expansion joint.

The connecting part of the high-end coal conveyor trestle and the low-end coal conveyor trestle is a stepped structure in which the connecting end of the high-end coal conveyor trestle is higher than the connecting end of the low-end coal conveyor trestle, and a part of space is reserved in the up and down and left and right directions. The expansion joint is located below the connecting end of the high-end coal conveyor trestle and at the position where it is connected to the low-end coal conveyor trestle. The surface of the connecting end of the high-end coal conveyor trestle, the expansion joint and the surface of the low-end coal conveyor trestle are all paved with a waterstop bent at the expansion joint position; the steel structure cover plates are respectively fixed to the waterstops on the surface of the connecting end of the high-end coal conveyor trestle and the surface of the low-end coal conveyor trestle.
[0008] A further improvement of the technical solution of the utility model is that the surface of the low-end coal conveying trestle below the connecting end of the high-end coal conveying trestle is convex upward to form a waterproof slope.
[0009] A further improvement of the technical solution of the utility model is that: the expansion joint is a fold line expansion joint.
[0010] A further improvement of the technical solution of the utility model is that the water stop belt and the steel structure cover plate are fixed to the high-end coal conveying trestle and the low-end coal conveying trestle by fasteners.
[0011] A further improvement of the technical solution of the utility model is that the high-end coal conveying trestle and the low-end coal conveying trestle are covered with a building surface layer.

While adapting to the horizontal deformation and uneven settlement of the trestle, gravity waterproofing is performed by relying on the structural shape, thereby enhancing the waterproof effect of the expansion joint.
[0015] Compared with the conventional coal conveying trestle expansion joint waterproof structure, the utility model water stop belt is curved at the expansion joint, which can better adapt to the structural deformation of the high-end coal conveying trestle and the low-end coal conveying trestle.

[0020] The present invention is further described in detail below in conjunction with the embodiments:
[0021] like Figure 1 As shown, the coal conveyor trestle is divided into a high-end coal conveyor trestle 1 and a low-end coal conveyor trestle 2. In order to avoid damage to the trestle body due to thermal expansion and contraction, an expansion joint is arranged between the two. In order to prevent pollution to the factory environment when flushing the coal conveyor trestle, a waterstop 4 needs to be arranged on the expansion joint for waterproofing. The deck of the conventional coal conveyor trestle expansion joint waterproof structure is a flat inclined surface, and a steel structure cover plate 5 is arranged above the waterstop 4. The steel structure cover plate 5 and the two ends of the waterstop 4 are fixed to the trestle deck by fasteners 6. The part of the trestle deck other than the steel structure cover plate 5 is the building surface layer 3 (the building surface layer 3 is cast later, and the fastening parts of the steel structure cover plate 5 and the waterstop 4 are cast together during casting). Under long-term operating conditions, this conventional expansion joint waterproof structure is prone to loosening and leakage at the waterstop 4, and the waterproof effect is poor. Black coal sludge water often leaks, causing pollution to the factory environment.
[0022] like Figure 2 As shown, the expansion joint of the utility model is of a broken line type, located below the connection end of the high-end coal conveying trestle 1 and at the position where it is connected to the low-end coal conveying trestle 2. The surface of the connection end of the high-end coal conveying trestle 1, the expansion joint and the surface of the low-end coal conveying trestle 2 are all paved with a water stop 4. The water stop 4 is curved at the expansion joint, which can better adapt to the structural deformation of the high-end coal conveying trestle 1 and the low-end coal conveying trestle 2. Compared with the conventional coal transport trestle expansion joint waterproof structure, on the basis of the waterproof of the water stop 4, the connection part of the high-end coal conveying trestle 1 and the low-end coal conveying trestle 2 is set as a stepped structure with the connection end of the high-end coal conveying trestle 1 higher than the connection end of the low-end coal conveying trestle 2, and a part of space is reserved in the up and down and left and right directions. This structure can perform gravity waterproofing while adapting to the horizontal deformation and uneven settlement of the coal conveying trestle, thereby enhancing the waterproof effect of the expansion joint.
[0023] The surface of the low-end coal conveying trestle 2 below the connection end of the high-end coal conveying trestle 1 of the utility model is convex upward to form a waterproof slope, which further prevents sewage from flowing into the expansion joint.
[0024] In the utility model, steel structure cover plates 5 are respectively arranged on the waterstop belts 4 on the connection end surface of the high-end coal conveying trestle 1 and the surface of the low-end coal conveying trestle 2, and the waterstop belts 4 and the steel structure cover plates 5 are fixed to the high-end coal conveying trestle 1 and the low-end coal conveying trestle 2 by fasteners 6; the high-end coal conveying trestle 1 and the low-end coal conveying trestle 2 are covered with a building surface layer 3, and the part of the waterstop belt 4 located on the trestle, the steel structure cover plates 5 and the fasteners 6 are all located in the building surface layer 3.
[0025] Working principle: Compared with the conventional coal transport trestles expansion joint waterproof structure, the utility model has a waterstop 4 that is bent at the expansion joint position, which can better adapt to the structural deformation of the high-end coal transport trestles 1 and the low-end coal transport trestles 2; on the basis of the waterproofness of the waterstop 4, the connecting part of the high-end coal transport trestles 1 and the low-end coal transport trestles 2 is set as a stepped structure in which the connecting end of the high-end coal transport trestles 1 is higher than the connecting end of the low-end coal transport trestles 2 and a part of space is reserved in the up and down and left and right directions, this structure can perform gravity waterproofing while adapting to the horizontal deformation and uneven settlement of the trestles, thereby enhancing the waterproof effect of the expansion joint; and an upwardly protruding waterproof slope is provided on the surface of the low-end coal transport trestles 2 below the connecting end of the high-end coal transport trestles 1, which further prevents sewage from flowing into the expansion joint, thereby completely solving the problem of water leakage in the expansion joint.
