Description

TECHNICAL FIELD

[0001] The application relates to the technical field of risk management and remediation of contaminated sites, in particular to a joint protection device for a vertical blocking super-deep flexible membrane joint. BACKGROUND

[0002] The vertical blocking technology is a technology for storing pollutants or changing the direction of groundwater by using underground blocking, aiming to control the migration of pollution levels and achieve the purpose of preventing the migration of underground pollutants. The vertical blocking technology requires that the blocking wall has very low permeability.

[0003] According to the vertical blocking form, the vertical blocking is generally divided into rigid vertical blocking and flexible vertical blocking. The rigid vertical blocking mainly uses continuous mud wall or cement wall to achieve the blocking purpose; the flexible vertical blocking mainly uses high-density polyethylene membrane (HDPE membrane) and supporting piles on both sides, and the end of the HDPE membrane is fixed on the supporting pile through a connecting buckle, so as to achieve the blocking purpose.

[0004] The Chinese patent with the publication number CN214994119U discloses an interlocking sealing device for connecting a flexible vertical cutoff wall system, which comprises a female buckle and a male buckle. The female buckle and the male buckle are made of HDPE material and can be connected with the HDPE membrane by hot melt welding. A longitudinal space is formed in the female buckle, and the longitudinal space has an opening. The male buckle is placed in the longitudinal space of the female buckle to form a buckle joint, and the opening is closed.

[0005] During the use of the above-mentioned technology, the female buckle is usually fixed on the supporting pile. During the construction process, the self-setting mortar may cause the female buckle to be blocked, so that the subsequent HDPE membrane joint cannot be installed on the supporting pile, and there is a deficiency.

[0012] Optionally, the mud blocking piece comprises a flexible mud blocking brush arranged on the flexible rubber strip, and the flexible mud blocking brushes on the two flexible rubber strips abut against each other.

[0013] By adopting the technical scheme, the external mud entering between the two guard plates is blocked by the two flexible mud blocking brushes abutting against each other, and when the flexible film is installed and fixed, the flexible mud blocking brushes on both sides of the flexible film abut against both sides of the flexible film, so as to reduce the way of mud and water diffusing and blocking the carabiner.

[0014] Optionally, the flexible mud blocking brush is arranged in an inclined manner, and the flexible mud blocking brush is inclined towards the carabiner along the direction from the carabiner to the flexible film.

[0015] By adopting the technical scheme, the flexible mud blocking brush arranged in an inclined manner can adapt to the change of the flexible film with different thicknesses, and is beneficial to reducing the possibility of the external mud entering between the two guard plates.
