Description

Technical Field

[0001] The present invention belongs to the technical field of pipe gallery installation, and more specifically, relates to a cable pipe gallery trough steel line shape control auxiliary device and a use method thereof. Background Art

[0002] With the acceleration of urbanization, the construction of underground integrated pipe corridors has gradually become an important part of modern urban infrastructure. Due to the long service life of the integrated pipe corridor, the laying, addition, reduction and maintenance of various pipelines can be carried out directly in the integrated pipe corridor, reducing repeated excavation of the road surface, providing the city with a safe and efficient pipeline operation environment and saving construction costs. Therefore, the construction of integrated pipe corridors is becoming more and more frequent in municipal road projects. In the construction process of the cable corridor, the channel steel is the main load-bearing and supporting structure. The accurate control of its line shape is directly related to the load-bearing capacity, stability, safety and service life of the entire structure. It is an important part of construction quality control. The appearance of the cable corridor is also part of the city's image. Effectively controlling the line shape of the channel steel can make the appearance of the corridor more tidy and beautiful. Therefore, in the construction process of the cable corridor, how to effectively control the line shape of the cable channel steel and ensure the standardization and stability of the cable layout has become a technical problem that needs to be solved urgently.

[0003] In the prior art, such as the patent document with application number CN202210339133.6, the invention provides a linear underground comprehensive pipe gallery intelligent walking outer formwork system and construction method, which is supported above the reinforced concrete of the first section of the pipe gallery by a longitudinal beam sliding device, and a steel pipe bracket supporting the longitudinal beam is arranged in the moving direction of the longitudinal beam in front of the reinforced concrete of the first section of the pipe gallery, and the longitudinal beam is pushed forward by the longitudinal beam pushing device; the crossbeam is installed with a transverse moving mechanism, and the moving end of the transverse moving mechanism is connected to the outer formwork, and the outer formwork is pushed outward or retracted inward by the transverse moving mechanism; the longitudinal beam, the crossbeam and the outer formwork are pushed together by the longitudinal beam pushing device to walk synchronously along the construction path of the pipe gallery. The template system of the invention is assembled by bolting, so it is easy to install and disassemble; the template system has high rigidity, which is conducive to the high standard waterproofing requirements of the pipe gallery and the construction quality of concrete; the walking system adopts a power trolley to push and walk, the pouring section of the pipe gallery adopts pulleys as tracks, and the uncast concrete section adopts steel pipe brackets + longitudinal and transverse beams as tracks, which is convenient for the intelligent walking of the outer formwork system. The formwork system is easy to construct, and the formwork can be installed and disassembled for repeated moving and pouring, but it cannot control the installation of the embedded channel steel of the bracket. For example, the patent document with application number CN202121399402.5 discloses a pipe gallery bracket auxiliary installation tool, including a main pole and at least one side pole, the side pole is horizontally arranged on the main pole, and the main pole is provided with a plurality of positioning plates, and the positioning plates are used for the installation and fixation of the longitudinal channel steel and the wall; the main pole is provided with a plurality of main pole screw holes at intervals, and the main pole screw holes are used for the positioning and installation of the support arm on the pipe gallery bracket. The pipe gallery bracket auxiliary installation tool provided by the utility model can quickly and accurately complete the positioning of the channel steel, anchor rod, and bottom cutting bolt, which greatly improves the installation efficiency of the pipe gallery bracket and reduces the construction cost of the pipe gallery bracket. It can be widely used in the installation of the pipe gallery bracket, but the device cannot effectively control the linear shape of the channel steel and the bracket support arm.

During the process of channel steel fixing construction and concrete pouring, the height and spacing of each channel steel are often inconsistent, resulting in uneven heights of the pipe gallery bracket arms and unsightly bracket lines.

A method for using a cable gallery channel steel linear control auxiliary device, which is implemented by using a cable gallery channel steel linear control auxiliary device as claimed in any one of claims 1 to 3, characterized in that: The specific implementation steps are as follows: S100: Preparation: Determine the installation height and spacing of the embedded channel steel (3) of the bracket according to the design drawing, and measure and mark the installation position of the channel steel on site; S200: Support structure setting and height adjustment: Install the support structure (2) at a predetermined position of the side wall of the pipe gallery, roughly adjust the support rod (21) of the support structure (2) to a predetermined height and then fix it with a buckle; place the longitudinal rod (11) on the longitudinal rod fixing buckle (23) of the support structure (2), and make fine adjustments with the fine adjustment screw (24); after reaching the specified height, flip up the hinge of the longitudinal rod fixing buckle (23) to fix the longitudinal rod (11); S300: Positioning and spacing adjustment of the crossbar: The crossbar (12) is passed through the gap between the longitudinal bars (11), and the pre-embedded spacing of the bracket pre-embedded channel steel (3) is obtained through the design drawing. The crossbar (12) is moved and adjusted using the scale on the longitudinal bar (11). After the spacing is adjusted to the spacing required by the drawing, the first screw (13) is vertically passed through the longitudinal bar (11) and the crossbar (12) to fix them; S400: Levelness check: Check whether the bubble in the level gauge (15) on the crossbar (12) is located in the middle position to determine whether the crossbar (12) is in a horizontal state. If it is found that the bubble is not in the middle position, fine-tune the height by adjusting the fine-tuning screw (24) until the bubble is in the middle position and the crossbar (12) is adjusted to a horizontal state; S500: Pre-buried channel steel installation: Place the channel steel connection fixture (16) in the groove of the cross bar (12), and clamp the bracket pre-buried channel steel (3) at the lower part of the channel steel connection fixture (16), adjust the bracket pre-buried channel steel (3) to be close to the steel templates on both sides, and then fix it to the channel steel connection fixture (16) by passing the second screw (14) horizontally through the cross bar (12); S600: Concrete pouring: After the installation and adjustment of the embedded channel steel (3) of the support are completed, the concrete pouring of the side wall of the pipe gallery is carried out; S700: Device removal: After the concrete reaches a certain strength, the support embedded channel steel (3) is separated from the channel steel connection fixture (16). After all the support embedded channel steels (3) are separated from the channel steel connection fixture (16), the auxiliary construction device for controlling the linear shape of the channel steel of the pipeline corridor is removed and moved to the next construction section.
