Multi-layer damping pile for overwater measuring platform

Abstract

The invention discloses a multi-layer damping pile for an overwater measuring platform. The multi-layer damping pile is characterized in that the upper end is buried in a water layer and penetrates asoft clay layer until arriving at a hard rock layer, and the upper end is positioned on the water layer and is used for supporting the measuring platform. The multi-layer damping pile comprises a first steel pipe layer, a second steel pipe layer and a third steel pipe layer which sequentially sleeve with each other from an outer layer to an inner layer; the bottom parts of the first steel pipe layer, the second steel pipe layer and the third steel pipe layer are aligned to each other; a filling space is formed between every two adjacent steel pipes; concrete is poured in a lower section of a filling space between the first steel pipe layer and the second steel pipe layer, a lower section of a filling space between the second steel pipe layer and the third steel pipe layer and in the thirdsteel pipe layer; fine sand is filled in the whole upper section of the filling space between the first steel pipe layer and the second steel pipe layer; and rubber is filled in an upper section of aspace between the second steel pipe layer and the third steel pipe layer. The multi-layer damping pile is obvious in damping effect and meets the requirement of a measuring device on vibration.

Description

technical field [0001] The invention belongs to the technical field of engineering survey, and in particular relates to a multi-layer damping pile for an above-water survey platform. Background technique [0002] In recent years, the construction of urban transportation facilities in my country has developed rapidly. During the construction of water transportation, it is necessary to build a water measurement platform. However, the water measurement platform is seriously affected by the impact of waves, causing the platform to vibrate, resulting in a decrease in accuracy. Affecting on-site construction, how to solve the vibration of the water measurement platform by waves has become a crucial issue. [0003] At present, the above-water platform mainly adopts reinforced concrete pile foundation. Mainly by increasing the diameter of the concrete pile, improving the strength of the concrete pile and reducing vibration. However, this method needs to increase the diameter of t...

Problems solved by technology

However, this method needs to increase the diameter of the concrete pile, resulting in an increase in the construction cost of the water platform, and this method can only slightly reduce the impact of vibration on the water measurement platform, and the increased diameter is not proportional to the weakened vibration

Therefore, only by increasing the diameter of the concrete pile cannot reduce the impact of vibration on the vibration of the water platform.
