Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a trestle main body structure. Background Art

[0002] During the tunnel construction process, the existing trestles are mainly erected on the excavated ground to facilitate the construction workers to pass through and the construction vehicles to transport building materials over the trestles.

[0003] The existing main structure of the trestle generally includes a bottom that provides a walking passage for construction personnel and construction vehicles. Both sides of the bottom are provided with side parts extending upward, forming a U-shaped structure as a whole. The side parts serve as guardrails and increase the overall strength. For example, a trestle disclosed in a Chinese patent with publication number CN213038175U describes the main structure of the trestle as follows: the trestle unit includes a trestle unit bottom and trestle unit side parts arranged on the left and right sides of the trestle unit bottom, and the lower parts of the two trestle unit side parts are connected to the trestle unit bottom, so that the trestle unit is a "U"-shaped frame structure; the walking passage is a space surrounded by the two trestle unit side parts and the trestle unit bottom, and the space is open at the top and the front and rear ends, that is, the walking passage is also in a "U" shape. The walking passage of this trestle main body needs to be not only for construction personnel to walk, but also for construction vehicles to walk. There is a great safety hazard when people and vehicles share a walking passage.

[0004] To this end, we designed a main structure of the trestle that separates people and vehicles. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses a trestle main structure.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0013] Preferably, the weight-reducing through holes are evenly spaced along the length direction of the T-shaped body and penetrate the T-shaped body along the width direction of the T-shaped body.

[0014] Preferably, track beams are provided on both sides of the belly of the T-shaped body.

[0015] Preferably, a limiting piece is provided at the end of the track beam.

[0016] Preferably, the vehicle passage is located directly above the two side walls of the personnel passage.

[0017] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0018] 1. Since the main body of the trestle is T-shaped, compared with the U-shaped in the prior art, the thickness of the main body of the trestle for carrying construction vehicles has been increased, so the structural strength has been effectively enhanced; and independent passages are provided for construction vehicles and construction personnel, realizing the function of separating people and vehicles, which is safer than the existing technology in which people and vehicles share one walking passage;

[0019] 2. The setting of the lighting window can ensure that the personnel passage has good lighting even when no lighting is used during the day;

[0020] 3. The setting of the sound-absorbing layer can absorb the noise generated by construction vehicles and vehicle passages, and effectively reduce the noise in the personnel passages. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1, in combination with the attached Figure 1-3 A trestle main structure includes a T-shaped main body 1, a vehicle passage 2 for construction vehicles to pass through is provided on the top surface of the wing of the T-shaped main body 1, and a personnel passage 11 for construction personnel to pass through is provided on the belly of the T-shaped main body 1.

[0027] Since the main body of the trestle is T-shaped, compared with the U-shaped in the prior art, the thickness of the trestle main body at the position where the construction vehicles are carried has been increased, so the structural strength has been effectively enhanced; and independent passages are provided for construction vehicles and construction personnel, realizing the function of separating people and vehicles, which is safer than the prior art in which people and vehicles share one walking passage.

[0028] As needed, the vehicle passage 2 is located directly above the two side walls of the personnel passage 11; it can be understood that the position of the wheels of the construction vehicle is located directly above the two side walls of the personnel passage 11; or, when the vehicle passage 2 has vehicle tracks, the vehicle tracks are located directly above the two side walls of the personnel passage 11.

[0029] Furthermore, since the trestle needs to be supported and moved by a movable support device when in use, so that the movable support device can move axially along the trestle body relative to the trestle body, track beams 3 are provided on both sides of the belly of the T-shaped body 1. Furthermore, a stopper 31 is provided at the end of the track beam 3.

[0030] Embodiment 2: In the actual construction process, especially during the shift change, the workers going to work and those leaving get off work go in opposite directions. Only one personnel passage 11 will affect the passing efficiency of the construction workers. Figure 1-3 , a trestle main structure, based on the first embodiment, two personnel passages 11 are provided at intervals along the belly width direction of the T-shaped main body 1 to facilitate the diversion of construction personnel coming and going;

[0031] It can also be said that an isolation structure is provided in the middle of the personnel passage 11 so that the personnel passage 11 is divided into two.

[0032] Furthermore, to ensure the brightness of the personnel passage 11, a plurality of lighting windows 12 are provided at intervals along the length direction of the T-shaped body 1 on the side wall of the personnel passage 11. Specifically, the size of the lighting windows 12 and the interval between adjacent lighting windows 12 are not specifically limited, so as to ensure that personnel can clearly see the internal situation of the personnel passage 11 during the day.

[0033] As needed, a lighting lamp can be provided on the top of the personnel passage 11 to ensure that the personnel passage 11 is bright and convenient for construction workers to pass through.

[0034] Embodiment 3: Since the personnel passage 11 will produce a large noise when the construction vehicles pass by, combined with the attached Figure 1-3 , a pier main structure, based on the first or second embodiment, a sound-absorbing layer 13 is provided on the inner wall of the personnel passage 11.

[0035] As required, the sound-absorbing layer 13 can be made of sound-absorbing materials such as sound-absorbing cotton and honeycomb panels.

[0036] The noise generated by the construction vehicles and the vehicle passage 2 in this way needs to pass through the sound-absorbing layer 13 before entering the personnel passage 11. After being silenced by the sound-absorbing layer 13, the noise in the personnel passage 11 can be effectively reduced.

[0037] Furthermore, a floor 14 is provided on the inner bottom surface of the sound-absorbing layer 13 ; this can prevent construction workers from directly stepping on the sound-absorbing layer 13 , and prevent debris carried by the soles of construction workers from penetrating into the sound-absorbing layer 13 .

[0038] As required, wall panels may be provided on both inner sides of the sound absorbing layer 13 .

[0039] Furthermore, a plurality of weight-reducing through holes 15 are evenly arranged between the top surface of the wing of the T-shaped body 1 and the upper part of the personnel passage 11 .

[0040] As required, the weight-reducing through holes 15 are evenly spaced along the length direction of the T-shaped body 1 and penetrate the T-shaped body 1 along the width direction of the T-shaped body 1 .

[0041] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
