Embodiment Construction
[0032] The present invention will be further described below in conjunction with specific examples.
[0033] A construction method for erecting T-beams in narrow spaces adjacent to existing lines, such as figure 1 shown, including the following steps:
[0034] 1) Construction preparation:
[0035] ① Check and accept the T beam with the supervisor, check the geometric dimensions, appearance quality and waterproof and drainage facilities of the beam; check and mark whether the T beam matches the corresponding pier, check the center line, center of gravity line and T beam installation direction, and Mark well, be clear, accurate and eye-catching;
[0036] ② Measure and release the cross line of the T-beam support, and check the span of the bridge;
[0037] ③ Near the existing line, close the hard isolation fence and anti-collision isolation pier, and paste reflective strips on the existing equipment to make the logo obvious;
[0038] ④Foundation testing, timely replacement of...

The invention discloses a construction method for erecting a T-beam in a narrow space adjacent to an existing line, and relates to the construction field of erecting a T-beam. Since the narrow space is only enough for the erection operation of two large crane stations, the beam transport vehicle does not have enough space to approach the work site. . In order to reduce the operating radius to within the range of the safety factor, the method of moving the beam forward is adopted. First, store the T beam on a nearby structure with sufficient bearing capacity to stabilize the beam and then move the crane to within the operating radius. Inner beam work. After the point is given, use two cranes to lift the beam frame to try to erect the T beam to the design center line. Before the pin point, the crane completed the withdrawal. The present invention can be applied to various narrow space occasions, and can be adaptively applied on the basis of the present invention according to specific environments. The method provided by the invention not only speeds up the construction progress, improves the construction efficiency, but also reduces safety risks; it leaves enough time for the development of follow-up projects.
Description
technical field [0001] The invention relates to the field of T-beam construction, in particular to a construction method for erecting a T-beam in a narrow space adjacent to an existing line, which is suitable for erecting a T-beam adjacent to an existing line where only a crane can be supported and a beam transport vehicle cannot approach in a narrow space. Background technique [0002] In the construction process near the existing line, ensuring the safe operation of the existing line is the focus of the work of the construction unit. The construction plan for the construction near the existing line is particularly important, especially the beam erection plan. Due to the construction near the existing line, the safety risk is high; the construction site is narrow, only enough for a large crane to stand, and the beam transport vehicle cannot be close to the work site; when erecting the beam, the bearing capacity of the temporary beam storage structure is high, so it is necess...
