Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0015] figure 1 and figure 2 A stable super-high observation tower for segmental beam prefabricated measurement is shown, including a steel pipe pile foundation buried underneath, a stable cap 2, a steel pipe column 3, a stable tie beam 4, a platform support 5, an observation platform 6, a protective Shed 8, combined safety ladder 11 and observation pier 13, the stable cap 2 is located on the ground, connected to the steel pipe pile foundation, the steel pipe column 3 is welded to the steel pipe pile foundation by three steel pipes, and passes through the stable cap 2. Concrete is poured inside, and the periphery is wrapped with double-layer geotextiles. The stable tie beam 4 is arranged in the middle and top of the steel pipe column 3, and is connected with three steel pipe columns 3 at the same time. Bearing the observation platform 6, the observat...

Abstract

The invention relates to a stable super-high observation tower for measurement in prefabricating of segmental beams. The observation tower comprises a steel pipe pile foundation buried in the ground, a fixing cushion cap, steel pipe stand columns, fixing collar beams, a platform support, an observation platform, a protection shelter, a combined safety ladder and an observation pillar. The fixing cushion cap locates on the ground and is connected with the steel pipe pile foundation. The steel pipe stand columns are welded with the steel pipe pile foundation through three steel pipes and passe through the fixing cushion cap. The top and middle of the steel pipe stand columns are provided with the fixing collar beams connected with three steel pipe stand columns. The bottom of the platform support is connected with the fixing cushion and the observation platform is arranged on the platform support. The observation platform locates on the platform support and is provided with the observation pillar through a circular hole. The protection shelter is connected with the top of the fixing cushion cap through a color steel plate and the platform support and surrounds three sides of the observation platform. An observation window is arranged at the upper position, within the observation sight, of the protection shelter. The combined safety ladder is hoisted and welded on one side of the observation platform, wherein the side of the observation platform is not provided with the protection shelter. The observation pillar is buried in steel pipe stand column concrete in advance.

Description

technical field [0001] The invention relates to a stable super-high observation tower for prefabricated measurement of segmental beams, which belongs to the field of bridge engineering. Background technique [0002] At present, domestic short-line method segmental beam prefabrication, the beam height generally does not exceed 4m, and the height of the observation platform of the observation tower set for it is generally controlled at 4~5m. In recent years, the prefabrication process of large-section segmental beams has been gradually promoted, and the beam height is about 9-10m. Since the height of the prefabricated bottom formwork from the ground is usually about 2m, the maximum prefabrication height of large-section segmental beams can reach 11-12m. Due to the relatively simple composition and structure of the current observation towers, which are often only composed of a single steel pipe pile, and there are imperfect reinforcement and protection measures, the commonly us...
