Simple removable drainage curtain for inspection and measurement of underwater pile foundations

Abstract

The invention relates to a simple removable drainage curtain for inspection and measurement of underwater pile foundations. The simple removable drainage curtain comprises hinges, waterproof rubber and thin plates; one end of each thin plate is Z-shaped while the other end is L-shaped, the bottom of each thin plate is provided with a saw blade, and Z-shaped ends and L-shaped ends of each two neighboring thin plates are respectively connected; each hinge is composed of pins, a holed half-hinge body, a holeless half-hinge body and a bolt, the hinge is pluggable, and the holed half-hinge body and the holeless half-hinge body are connected with the bolt to form a revolute pair; holes matched with the bolts is arranged in the plane of the Z-shaped end of each thin plate, and the thin plate is connected with the holed half-hinge body through the bolt and is in glue joint with the holeless half-hinge body on the plane of the L-shaped end of each neighboring thin plate. The simple removable drainage curtain has the advantages that heads of the pile foundations are allowed to expose out of water surface with in a short time through drainage, technical work such as subsequent pile foundation detection or positioning measurement are facilitated, working efficiency is improved, time cost is saved, and economic input is reduced.

Description

technical field [0001] The invention relates to a drainage curtain, more specifically, it relates to a simple and detachable drainage curtain for inspection and measurement of underwater pile foundations. Background technique [0002] In civil engineering, such a situation is often encountered: after the foundation pit is excavated, the pile foundation driven into the ground is submerged due to the infiltration of surrounding water sources or rainfall, and the water surface is relatively large, forming a pond shape. Because all the pile foundations in the foundation pit are submerged by water, and the water depth is relatively deep, if you want to measure the specific pile foundation position or check the designated pile at this time, you must require the pile foundation head to be exposed to the water. [0003] Pumping water directly to make the head of the submerged pile foundation emerge from the water surface requires a large amount of drainage work, which is time-consum...

AI Technical Summary

Problems solved by technology

[0003] Pumping water directly to make the head of the submerged pile foundation emerge from the water surface requires a large amount of drainage work, which is time-consuming and labor-intensive. It is necessary to use high-power pumping equipment to ensure that the pumping speed is greater than the inflow speed of the water source, so that the pile foundation can be exposed to the water surface, but this method undoubtedly requires a lot of time and economic investment.

To sum up the above problems: 1. Direct drainage, large drainage; 2. There may be inflow of external water sources, resulting in invalid drainage or slow drainage
