Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0024] see Figure 1-Figure 3 , a V-shaped seam forming device, including a first rubber strip 310 and a second rubber strip 320, the end faces of the first rubber strip 310 and the second rubber strip 320 are triangular, preferably, the first The end surface of the rubber strip 310 is an isosceles triangle, and the end surface of the second rubber strip 320 is a right triangle;

[0025] After the tip of the second rivet 420 passes through the steel plate 500, the second rubber strip 320 is fixed on the steel plate 500. The large end 421 of the second rivet 420 is closely fixed to the panel 100 of the initial construction trolley, and the steel plate 500 and the initial construction The trolley panel 100 is welded and fixed.

[0026] A V-shaped seam forming process based on the above-mentioned V-shaped seam forming device, comprising the steps of:

Abstract

The invention discloses a V-shaped seam forming device. The V-shaped seam forming device comprises a first rubber strip and a second rubber strip, wherein the end faces of the first rubber strip and the second rubber strip are triangular, after the tip end of a second rivet penetrates through a steel plate, the second rubber strip is fixed on the steel plate, the large end of the second rivet is tightly fixed on a panel of an initial lining trolley, and the steel plate is welded and fixed on the panel of the initial lining trolley. The invention further discloses a V-shaped seam forming technology based on the V-shaped seam forming device. The problem of large area tunnel lining cracking diseases which pass through karst geology is effectively solved through the V-shaped seam forming device and technology. According to the V-shaped seam forming device and technology, pressure and tension in the circumferential and longitudinal directions are released through a V-shaped notch, and circumferential and longitudinal cracks caused by uneven stress distribution at construction joints of secondary lining concrete are avoided. The first rubber strip and the second rubber strip can be reused 10 times or above, while a traditional cutting machine takes 2 days to cut a ring with an average of 5 cutting pieces to be replaced. Compared with the traditional cutting machine, the V-shaped seamforming device can realize cost saving and shorten the operation time.

Description

technical field [0001] The invention relates to a tunnel construction technology, in particular to a V-shaped seam forming device and its technology. Background technique [0002] In recent years, China has entered a period of high-speed railway construction and development, and several high-speed railways have been opened to traffic in the southwest region. In the previous tunnel construction process and tunnel completion acceptance, longitudinal and circumferential cracks existed in the tunnel lining construction, and the cost of later rectification and maintenance was extremely high, which brought great risks to project cost control. According to the traditional technology, after the tunnel construction is completed, the construction team can use the grinder to cut the tunnel lining (groove), which is time-consuming and labor-intensive, and it is not conducive to saving construction costs. [0003] Therefore, the applicant proposes a V-shaped seam forming device and its ...
