Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tool for installing deep-buried culverts in tunnels. Background Art

[0002] Due to weather conditions, tunnels in northern China often bury drainage culverts deep at the base of the invert to prevent them from freezing. Due to the thermal expansion and contraction of ice on the culverts, the surrounding concrete can crack, impacting the service life of the culvert's ancillary works. Therefore, the quality of the deeply buried culverts is crucial for drainage interception. Due to the varying slopes of tunnels, high requirements are placed on the slopes of the deeply buried culverts at different locations. Traditional culvert installation methods use slings for integral lifting. Adjusting the culvert's slope to align with the tunnel's slope requires repeated lifting and lowering, resulting in lengthy installation times. This process can also damage the concrete at the base of the culvert, leading to inaccurate installation. Therefore, improvements are urgently needed in culvert lifting equipment to adjust the culvert's slope and improve installation accuracy. Utility Model Content

[0003] The problem to be solved is to improve the culvert lifting equipment so that the slope of the culvert can be adjusted and the installation accuracy of the culvert can be improved.

[0020] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention:

[0021] In order to solve the problems raised in the background technology, the utility model provides a tool that can adjust the angle of the culvert, which includes two culvert hangers 4, which are relatively arranged at both ends of the culvert 1, and the cross-section of the culvert hanger 4 is concave, and the concave groove is a hanger groove 42, and the hanger groove 42 faces the culvert. The two sides of the hanger groove 42 are respectively an upper connecting block 41 and a lower connecting block 43. The longitudinal height of the hanger groove 42 is greater than the thickness of the culvert 1, which is convenient for adjusting the culvert 1 in the hanger groove 42; a connecting hole 411 is provided on the upper connecting block 41, and the connecting hole 411 is connected to the lifting equipment; a spiral rod 431 is passed through the lower connecting block 43, and the length of the spiral rod 431 is greater than the length of the hanger groove 42. In terms of longitudinal height, the spiral rod 431 is rotatably connected relative to the lower connecting block 43, and a thread that cooperates with the spiral rod 431 is provided at the connection between the lower connecting block 43 and the spiral rod 431; an adjusting dial 432 is connected to the lower end of the spiral rod 431, and the construction personnel can rotate the adjusting dial 432 when the height needs to be adjusted; the upper end is connected to the culvert tray 433, and the culvert tray 433 is a curved surface, and the curved surface radius of the culvert tray 433 is the same as the inner diameter of the culvert 1. The bottom center of the culvert tray 433 is fixedly connected to the upper end of the spiral rod 431, and the culvert tray 433 can also abut against the inner wall of the culvert 1 through the rubber pad 434. The rubber pad 434 plays a buffering role to prevent the culvert tray 433 from damaging the inner wall of the culvert 1. Two culvert hangers 4 are suspended at both ends of the steel plate 2 through their respective connection holes 411. The culvert hangers 4 are suspended at both ends of the steel plate 2 through iron chains 3. There is a steel plate hole 1 21 and a steel plate hole 2 22 at both ends of the steel plate 2 respectively. The steel plate hole 1 21 is connected to one culvert hanger 4 through the iron chain 3, and the steel plate hole 2 22 is connected to another culvert hanger 4 through the iron chain 3. The hanger grooves 42 of the two culvert hangers 4 are opposite to each other; the iron chain 3 can be bent to facilitate the lifting of culverts 1 of different lengths.

[0022] A hook hole 5 is integrally formed above the center of the steel plate 2, which connects to the hook of the lifting equipment. To enhance the stability of the equipment, the top of the hook hole 5 spans the center of a welded steel frame 6, the ends of which are welded to the ends of the steel plate 2, forming a stable triangular support structure. Triangular trusses 7 are also provided on both sides of the hook hole 5, connecting the steel frame 6 and the steel plate 2 to increase the equipment's load-bearing capacity and stability. Generally, the horizontal projection area of ​​the rubber pad 434 is larger than the horizontal projection area of ​​the culvert tray 433. That is, the area of ​​the rubber pad 434 must be larger than the area of ​​the culvert tray 433 to cover the culvert tray 433, preventing the inner wall of the culvert 1 from directly contacting the culvert tray 433. The rubber pad 434 can also have the same structure as the culvert tray 433.

[0023] like Figure 3 As shown in the schematic diagram of the principle of the utility model tooling, the lower connecting blocks 43 at both ends are always at the same height. The inclination angle of the tunnel under construction is ɑ, so the angle required for the culvert 1 is also ɑ. Figure 3 It can be seen that the horizontal distance between the two screw rods 431 is L, the horizontal distance L is a constant, the lifting height of the left screw rod 431 is h, and the lifting height of the right screw rod 431 is H. ɑ is related to H and h, that is, tanɑ=(Hh) / L. The tangent value of the desired angle ɑ is proportional to the height difference between the two screw rods 431. Therefore, if you want to obtain the accurate angle ɑ, you can adjust the lifting height of the two screw rods 431 accordingly.

[0024] During use, the required inclination angle ɑ of the culvert 1 is determined according to construction requirements. The culvert 1 needs to be placed on the bottom concrete poured at the bottom of the inverted arch. If ɑ is not accurate, the culvert will be repeatedly lifted and lowered, which will damage the concrete base of the inverted arch. After the inclination angle ɑ and the horizontal distance L between the two screw rods 431 are determined, the height difference between the two screw rods 431 when they are lifted is L*tanɑ. Therefore, it is sufficient to ensure that the height difference between the screw rods 431 on both sides is L*tanɑ, that is, Hh=L*tanɑ. After the various parts of the tooling are installed in place, the corresponding lower connecting blocks 43 are placed at each end of the culvert 1. If one of the screw rods 431 is lifted by h, the screw rod 431 at the other end will be lifted by H, where H=L*tanɑ+h. The hook of the lifting equipment is hooked into the hook hole 5 to transport the culvert 1 to the predetermined position.

[0025] The above embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
