Embodiment Construction

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0021] See figure 1 As shown, the integrated construction method of pile-planting cofferdam platform for low pile caps in rock formations in the embodiment of the present invention includes the following steps:

[0022] S1: Simultaneous construction of lifting platform 1 and drilling platform 2 on the rock formation, lifting platform 1 is located around drilling platform 2; during the construction of lifting platform 1 and drilling platform 2, the lifting platform 1 and drilling platform The cofferdam construction channel 3 is reserved between 2 and the cofferdam platform panel is laid on the cofferdam construction channel 3 to serve as the cofferdam construction platform and drilling platform, and go to S2.

[0023] S2: Cofferdam construction is performed on the drilling platform 2 on the cofferdam construction platform, and at the same time, the p...

Abstract

The invention discloses an integral construction method of a pile planting cofferdam platform used for a rock strata low-pile cap and relates to the field of construction of rock stratum low-pile caps. The integral construction method comprises the following steps that S1, a lifting platform and a drilling platform are constructed on a rock stratum at the same time, and a cofferdam construction channel is reserved between the lifting platform and the drilling platform in the lifting platform and the drilling platform construction process; and S2, cofferdam construction is conducted on the drilling platform in the cofferdam construction channel, and pile foundation drilling is conducted on the drilling platform at the same time; during the cofferdam construction, after steel sheet piles required by a cofferdam are planted into the rock stratum through a static-pressure pile planting machine, a steel sheet pile cofferdam inner supporting structure is installed, water drawing is conducted in the cofferdam, and an excavator is lifted into the cofferdam for conducting no-water excavation.. According to the integral construction method, underwater blasting is changed into no-water excavation, the construction period is short, required manpower and material resources are few, and construction requirements can be met.

Description

Technical field [0001] The invention relates to the field of construction of low-pile caps in rock formations, in particular to an integrated construction method for pile-planting cofferdam platforms for low-pile caps in rock formations. Background technique [0002] At present, the traditional construction method for low-pile caps in rock formations is: first carry out underwater blasting operations, and then construct drilling platforms and cofferdams. However, for piles with fast flow rates and underwater blasting operations that cannot be implemented, traditional construction methods not only require huge investment of manpower and material resources, but also have a long construction period, which is difficult to meet the construction requirements. . Summary of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is to provide an integrated construction method for pile-planting cofferdam platform for low pile caps in rock format...
