Constructing method of constructing structure of underwater bearing platform

Abstract

The invention discloses a constructing method of a constructing structure of an underwater bearing platform. The method includes the steps that a pouring jacket bottom plate with reserved holes formedis assembled on land, and a blocking-up layer is arranged on the pouring jacket bottom plate; a bearing platform reinforcement cage is bound on the blocking-up layer; remaining assemblies of a pouring jacket are mounted on the bearing platform reinforcement cage so as to form a whole lowering structure of the constructing structure of the underwater bearing platform; when the end of a to-be-butted steel protecting barrel is exposed during tide falling, the whole lowering structure is lifted in place; blocking-up concrete is filled at the blocking-up layer; and bearing platform concrete is filled in the range of the bearing platform reinforcement cage, and after the bearing platform concrete is solidified, the pouring jacket is removed. According to the constructing method, by pre-assembling the whole lowering structure and lowering the whole lowering structure during tide falling, the hydrologic conditions can be effectively used for constructing, the construction period is shortened,structures like sealing concrete are saved, resources are saved, and costs are reduced; and the conflict problem between the bearing platform reinforcement cage and protecting barrel steel bars are avoided through the method of connecting the steel bars, and the fact that the lowering process is carried out smoothly is ensured.

Description

technical field [0001] The invention mainly relates to the construction field, in particular to a construction method applied to the construction structure of an underwater bearing platform. Background technique [0002] In the construction of bridges across water bodies, it is often necessary to construct in water body areas, which requires the application of underwater construction methods and construction techniques. At present, in the construction of bridges in water bodies such as rivers and seas, hydrological factors such as the time of high tide, low tide, time interval between high tide and low tide, and tidal range water level need to be considered. At high tide, the caps of the bridge are submerged under the water. At low tide, the platform part is completely exposed above the water surface. Due to the many hydrological factors that need to be considered, the construction can only be carried out during the period of complete low tide, and the time is extremely sh...

AI Technical Summary

Problems solved by technology

The method of the prior art results in that the back cover concrete does not function as a back cover at low tide

However, if there is no bottom-sealing concrete for the casing at the high tide level, it will cause the casing to be eroded by tide water

[0004] On the other hand, during the construction of the underwater cap, the pile foundation reinforcement often collides with the inner cap reinforcement of the casing, which will lead to problems such as inaccurate construction positioning

In addition, when the tide rises, the tide will support the bottom of the cap structure due to buoyancy, which will affect the stability of the cap structure
