Height detection device for suspension bridge open caisson mud suction

Abstract

The invention belongs to the technical field of open caisson platform mud suction, and particularly relates to a height detection device for suspension bridge open caisson mud suction. The height detection device comprises an open caisson platform, the upper surface of the open caisson platform is fixedly connected with a supporting column, and the upper surface of the supporting column is fixedly connected with a limiting sliding plate and a middle sliding plate; an axial movement adjusting device is arranged in the limiting sliding plate and the middle sliding plate and longitudinally moves on the upper surface of the open caisson hole, and a radial movement adjusting device is arranged on the surface of the axial movement adjusting device and radially moves on the upper surface of the open caisson hole; and a mud suction device is arranged on the lower surface of the radial movement adjusting device, and in the moving process of the mud suction device, mud on the inner bottom wall of the open caisson hole is extracted, and sinking of the open caisson platform is facilitated. According to the height detection device for suspension bridge open caisson mud suction, the distance between the stainless steel probe and the sludge interface and the distance between the stainless steel probe and the bottom surface are detected through the stainless steel sludge interface instrument according to the reliable ultrasonic echo detection principle, and convenience and rapidness are achieved.

Description

technical field [0001] The invention relates to the technical field of mud suction on caisson platforms, in particular to a height detection device for mud suction in caissons of suspension bridges. Background technique [0002] The caisson platform is a type of underground structure and deep foundation constructed by the caisson method. It is first made into a well-shaped structure (caisson) on the surface, and then passes through the well continuously under the enclosure of the well wall. Excavate the soil to make the caisson sink gradually under the action of its own weight. After reaching the predetermined design elevation, seal the bottom and build the internal structure. It is widely used in the foundation of bridges, chimneys, water towers; deep well structures such as water pump rooms, underground oil depots, and pool shafts. and working wells for shielding or pipe jacking. [0003] However, when the existing caisson platform measures the distance from the horizonta...

Problems solved by technology

[0004] Based on the existing caisson platform, the device is not only unstable when measuring the distance from the horizontal surface to the sediment, but also the measurement accuracy is not enough, which brings difficulties to the work of the suction pipe to extract the sediment, thereby reducing the working efficiency of the sediment extraction. Problem, the present invention proposes a height detection device for suspension bridge caisson suction mud
