Technical Field

[0001] The utility model relates to the technical field of secondary lining construction, and in particular to a construction device for a secondary lining steel frame of a small-section tunnel. Background Art

[0002] At present, the country attaches great importance to environmental protection. During construction work, construction red lines are strictly controlled. When gas pipelines, water supply and drainage pipelines and other pipeline operations need to cross mountains, most construction units will use tunnel crossing methods to solve the problem.

[0003] Since the diameter of the pipelines that need to be crossed during construction is generally small, resulting in a small tunnel section, the existing technology generally uses a steel bar manufacturing trolley to manufacture and install the secondary lining steel bars on site. This results in extremely small working space during steel bar installation, which brings inconvenience to the construction work and frequent safety accidents for workers, which not only reduces the workers' work efficiency, but also reduces the safety of workers.

[0004] Based on the above situation, it is urgent to develop a construction device that can solve the problem of insufficient construction space and ensure the safety of workers. Utility Model Content

[0029] In view of the problems of small working space and frequent safety accidents in the conventional secondary lining steel bar production in the prior art mentioned above, the utility model proposes a construction device for a secondary lining steel bar skeleton of a small-section tunnel.

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] This embodiment discloses a construction device and a method for using a secondary lining steel frame for a small-section tunnel. Figure 1 The side structure of the tire frame assembly in the construction device of the secondary lining steel frame of the small-section tunnel is shown. Figure 2 The front structure of the tire frame assembly in the construction device of the secondary lining steel frame of the small-section tunnel is shown. Figure 3 The side structure of the transport trolley involved in the construction device of the secondary lining steel frame of the small-section tunnel is shown.

[0032] Please refer to Figures 1 to 3The utility model of the construction device and the use method of the secondary lining steel frame of the small and medium-section tunnel are specially designed for the production and transportation of the secondary lining steel frame in the tunnel project, and include: a tire frame assembly 1 and a transport trolley 2. The secondary lining steel frame is produced by an off-site steel bar factory, and then the steel frame is fixed by the tire frame assembly 1, and the transport trolley 2 drives the transport tire frame to transport the steel frame to the installation point for installation, and then the transport trolley 2 withdraws for secondary transportation until the transportation of the steel frame is completed. The device significantly improves the efficiency and safety of tunnel construction with its unique structure and efficient transportation method.

[0033] During the production of the steel skeleton, a positioning device is specially set up. The use of the positioning device not only improves the construction efficiency, but also reduces the error rate of manual operation, providing a strong guarantee for the safety and quality of tunnel construction.

[0034] Outside the tunnel, a tire frame assembly 1 is provided, which is composed of a plurality of support frames 2, which are fixed to each other by connecting rods to form a stable structure. The support frames 2 are arched, which not only enhances the stability of the structure, but also facilitates the fixation and transportation of the tire frame assembly 1 on the transport trolley 2.

[0035] Positioning tubes 12 are installed on the support frame 2. The main function of these positioning tubes 12 is to determine the distance and position of the steel bars, so that the accuracy and stability of the steel bar skeleton can be ensured when the steel bar skeleton is installed, and the steel bar skeleton is more convenient and faster to fix using the tire frame assembly 1. The positioning tubes 12 adopt a retractable design, which can be flexibly adjusted according to the length, width and height of the steel bar skeleton to meet the construction requirements of tunnels of different sizes.

[0036] A transport trolley 2 is provided on one side of the tire frame assembly 1. The design of the transport trolley 2 fully considers the complex environment and construction requirements in the tunnel. The front part of the trolley is designed to be light and strong, which is convenient for flexible shuttle in the narrow tunnel. A transport platform is installed on one side of the front part of the trolley. This transport platform adopts a flat plate design, which can bear the weight of the steel frame and ensure stability during transportation.

[0037] In order to further improve the transportation efficiency and safety, a jack 21 is also installed on the transport platform. When the steel frame needs to be transported to the installation point in the tunnel, the jack 21 can lift the tire frame assembly 1 and fix the tire frame assembly 1 and the steel frame on the transport platform. In this way, the transport trolley 2 can easily transport the steel frame to the designated location, greatly improving the construction efficiency.

[0038] like Figure 4 The construction device of the secondary lining steel frame of the small-section tunnel is used to carry out construction in the small-section tunnel, and the specific process includes:

[0039] S1: manufacturing a steel bar skeleton in a steel bar factory according to the needs of the tunnel construction;

[0040] S2: Determine the distance between the steel skeletons according to construction requirements, adjust the distance between the positioning tubes in the tire frame assembly, and use the tire frame assembly to determine the spacing between the steel skeletons;

[0041] S3: After the plurality of steel bar skeletons with determined spacing are tied together, the tire frame assembly and the steel bar skeleton are transported by the transport trolley, and the steel bar skeleton is transported to an installation point in the tunnel;

[0042] S4: Fix the steel bar skeleton to complete the installation of the secondary lining steel bars;

[0043] S5: The transport trolley is moved outside the tunnel, the second lining trolley in the tunnel is molded and then concrete is poured.

[0044] In S1 and S2, when using the construction device, it is first necessary to make a steel skeleton according to construction needs and determine the distance between the steel skeletons according to construction needs. Then, adjust the position of the positioning tube 12 in the tire frame assembly 1, and transport the steel skeleton to the installation point in the tunnel through the transport trolley 2.

[0045] In S3 and S4, the jack 21 of the transport trolley 2 can lift the tire frame assembly and the steel frame and fix them on the transport platform to ensure stability and safety during transportation. After the steel frame is transported to the installation point, the transport trolley 2 needs to be moved outside the tunnel to prepare for the next transportation. The steel frame is fixed in the tunnel, and embedded steel bars are pre-set at the installation point. By connecting the steel frame with the embedded steel bars, the firmness and stability of the steel frame can be ensured, and the installation of the secondary lining steel bars can be completed.

[0046] In S5, after the installation of the secondary lining steel bars is completed, first, the transport trolley 2 is moved outside the tunnel, and then the secondary lining trolley is used in the tunnel hole to perform a mold closing operation to prepare for the subsequent concrete pouring. Finally, the concrete pouring work is carried out to complete the secondary lining construction of the entire tunnel.

[0047] By using this small-section tunnel secondary lining steel skeleton construction device, the efficiency and safety of tunnel construction can be effectively improved. The device has a stable structure and is easy to operate, and can meet the construction needs of tunnels of different sizes. At the same time, its unique transportation method and positioning device ensure the accuracy and quality of the steel skeleton, providing a strong guarantee for the safety and quality of tunnel construction.

[0048] In addition, the construction device is highly flexible. The retractable design of the positioning tube 12 and the jack 21 enables the device to adapt to tunnels of different sizes and different construction requirements. At the same time, the lightness and flexibility of the transport trolley 2 also enable it to shuttle freely in narrow tunnels, greatly improving construction efficiency.

[0049] In general, this construction device for the secondary lining steel frame of a small-section tunnel is an efficient, safe and flexible tunnel construction solution. It greatly solves the problems of inconvenience in the construction of the secondary lining steel frame and operational safety risks caused by insufficient width of the working surface of a small-section tunnel.
