Description

Technical Field

[0001] The present application relates to the technical field of concrete main tower construction, and in particular to a cable guide tube positioning device and a construction method suitable for a cross anchoring area. Background Art

[0002] The cable-stayed bridge is a highly hyperstatic structure with complex forces, great mutual influence between components, and artificially controllable internal forces and linearity. Among them, the cable guide is one of the important components in the anchoring area of ​​the cable. Its precise positioning and installation can effectively prevent the cable from being damaged by friction with the cable guide tube wall, which affects the quality of the cable-stayed bridge. The welding process of the cable guide and the subsequent concrete pouring process of the bridge beam are prone to position deviation of the already positioned cable guide. Once the cable guide has position deviation, it is easy for the cable to rub against the cable guide during the subsequent tensioning of the cable, affecting the overall force of the cable. Since the cable and the bridge tower are at a spatial angle, and the position of each layer of cable and the bridge tower is different, the angle of the cable will also change accordingly. At the same time, the cross-anchored cable is more complex in spatial position, which makes its design put forward higher requirements for parts cutting, processing and cable guide tube positioning.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] The embodiments of the present application provide a cable guide tube positioning device and a construction method suitable for a cross-anchoring area, which can solve the problem in the related art that the cable guide tube positioning construction in the cross-anchoring area requires repeated measurements and fixing or releasing the connection, and has low construction accuracy and low efficiency.

[0024] Since the conventional cable guide positioning construction requires the production of a positioning frame first, the positioning frame is welded to the tower column, and then the cable guide is hoisted, and the cable guide is welded to the positioning frame after measurement and positioning. Since the cable guide installation belongs to the three-dimensional space positioning operation, it needs to be repeatedly measured, fixed, and disconnected during installation, and the construction accuracy is low and the efficiency is not high. Then, a positioning installation frame that can be hoisted to the installation area together after preliminary positioning and a component of a fine-tuning cable guide detachably connected thereto are designed, so as to realize the preliminary positioning of the cable guide on the ground conveniently, and then hoist it as a whole to the tower column construction section, which can reduce high-altitude operations, facilitate cross-parallel operations, improve work efficiency, and shorten the construction period; then, in the installation area, the fine-tuning components are used to accurately position each part of the cable guide to meet the construction and installation standards, and after the cable guide is fine-tuned and positioned, the fine-tuning components can be removed and used in the next section, saving materials and effectively reducing construction costs. The problem that the cable guide positioning construction in the cross-anchoring area in the related technology requires repeated measurement and fixing or disconnection, and the construction accuracy is low and the efficiency is low is solved.

The upper longitudinal positioning component 4 is installed on the crossbeam frame 3 and is suspended with the cable guide tube 5. The upper longitudinal positioning component 4 has the function of adjusting the length of the suspension, and can adjust the longitudinal elevation and inclination angle of the cable guide tube 5 to ensure that it can be adjusted according to construction requirements. The lower longitudinal positioning component 6 is installed on the corresponding vertical frame 2, which can also adjust the longitudinal elevation and inclination angle of the cable guide tube 5, and cooperate with the upper longitudinal positioning component 4 to fully and accurately adjust the elevation and inclination angle of the entire cable guide tube 5; the transverse positioning component 7 is also arranged on the corresponding vertical frame 2, which is adjustably connected to the cable guide tube 5, and performs transverse positioning and adjustment of the cable guide tube 5 to achieve flexible adjustment of the transverse position.

This structural design strengthens the positioning function of the cable guide tube 5 and significantly improves the stability of the entire structure. The locking assembly 10 connects the hanging frame assembly 9 and the cable guide tube 5, and fixes the cable guide tube 5 in the longitudinal direction through the locking mechanism. Once adjusted to a suitable position, the locking assembly 10 ensures that the cable guide tube will not move due to external forces, thereby ensuring the safety and stability of the construction.

The design of the first adjustment member is intended to achieve an adjustable connection between the steel wire rope 8 and the second lifting lug 101. Similarly, by changing the length of the first adjustment member, the longitudinal elevation of the lower portion of the cable guide tube 5 is adjusted and positioned, and the upper longitudinal positioning assembly 4 is cooperated to achieve complete longitudinal elevation adjustment and positioning of the cable guide tube 5.
