Pile foundation construction platform erection method

Abstract

The invention discloses a pile foundation construction platform, which comprises a supporting body, wherein an excessively grouted pile foundation is fixed at the lower end of the supporting body; the lower part of the excessively grouted foundation is connected with a structural pile foundation; and the steel platform is erected on the top of the supporting body. The invention also discloses an erection method for the pile foundation construction platform. The erection method comprises the following steps of: firstly, preferably drilling the pile foundation of the pile foundation construction platform by an island building construction method in a dry season; secondarily, excessively grouting the pile foundation, and embedding the supporting body into the excessively grouted foundation; and finally, erecting the steel platform on the supporting platform in a wet season. According to the pile foundation construction platform, characteristics of construction in the dry and wet seasons in a shallow-water region are adopted, and advantages of the island building construction method and a steel platform construction method are fully combined, so that the pile foundation is continuously and quickly constructed without being influenced by a water level.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a method for erecting a pile foundation construction platform. Background technique [0002] At present, for the construction methods of pile foundations in shallow water areas, the island construction method and the steel platform construction method are mainly used. [0003] When using the island construction method to carry out drilling work, first pile up artificial islands above the water surface near the pile position, transform the water surface construction into land construction, and then place equipment on it for drilling operations. The island construction method simplifies the water area Drilling equipment and technology, fast construction and reduced engineering costs, but the island construction method is only suitable for construction operations in dry seasons, and the water level is greatly affected by the wet season, and the island construction m...

[0003] When using the island construction method to carry out drilling work, first pile up artificial islands above the water surface near the pile position, transform the water surface construction into land construction, and then place equipment on it for drilling operations. The island construction method simplifies the water area Drilling equipment and technology, fast construction and reduced engineering costs, but the island construction method is only suitable for construction operations in dry seasons, and the water level is greatly affected by the wet season, and the island construction method will not be able to carry out construction during the rising water level Operation

[0004] When using the steel platform construction method, it is necessary to construct the foundation of the steel platform first, then build the steel platform on the foundation, then use the steel platform as a support to set up the pile driver, and then carry out the piling operation. Although this construction method is not affected by the water level, However, the erection of the steel platform requires a long construction period, which affects the overall construction progress
