Description

Technical Field

[0001] The utility model relates to the technical field of flexible vertical anti-seepage, and specifically to a self-clamping vertical box for lock protection, which is specifically used to provide protection for the lock after the flexible anti-seepage unit is installed to prevent the lock from being blocked by slotted debris and backfill. Background Art

[0002] During the construction of flexible vertical anti-seepage membrane, it is inevitable that the trench of the rear anti-seepage unit will be excavated after the installation of the first anti-seepage unit. During the excavation process, the mud and rock and soil debris will disturb the turbulent flow in an disordered manner, which will easily cause the lock of the first anti-seepage unit to be blocked. Once blocked, it will affect the installation of the rear anti-seepage unit and affect the construction progress and quality. In addition, for the surrounding closed flexible vertical anti-seepage, when the anti-seepage unit is closed, the first installed anti-seepage unit needs to provide better protection for the lock, otherwise it will cause the lock to be blocked.

[0003] Based on the above problems, Patent ZL201520786995.9 discloses a protective device for a flexible vertical anti-seepage wall connecting lock strip, including a front construction slot section, a rear construction slot section and a HDPE insert film, and a connecting lock strip is arranged at the end of the HDPE insert film, including a lock strip protection frame and an isolation frame, and the lock strip protection frame is two front construction slot sections respectively arranged on the front and rear sides of the HDPE insert film corresponding to the inner side of the connecting lock strip on the HDPE insert film, and the isolation frame is arranged in the front construction slot section located on the outside of the connecting lock strip and 1 meter away from the rear construction slot section. Although this patent also plays a protective role for the first construction connecting lock strip, the actual implementation process is relatively cumbersome, the efficiency is low, and the verticality of the installation is difficult to control.

[0004] Patent ZL201921402190.4 discloses a protective device and a flexible membrane assembly for a flexible membrane buckle, wherein a link lock is arranged at the edge of the membrane, and the protective device comprises: a protective shell and at least one fracture, wherein the fracture is located on the side wall of the protective shell, and the protective shell can be inserted at the edge of the flexible membrane through the fracture, and the link lock cover is arranged in the protective shell. Due to the existence of the fracture in this patent, during the construction process, under the disordered disturbance and turbulent flow of the underground mud, the grooved impurities can easily enter the protective shell through the fracture, causing the lock to be blocked.

[0005] When installing the sectional units of the flexible vertical anti-seepage system, the protection of the lock is an unavoidable and important problem. The lock protection device has high requirements, and the protection device is required to be simple to set up and easy to operate, and at the same time, it does not affect the trough excavation of the lower sectional unit. Although the above lock protection devices have played a certain role, they all have different problems. Based on the above technical situation and technical difficulties, it is a problem that technicians in this field need to consider and overcome. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0027] like Figures 1 to 3 As shown, the utility model provides a self-clamping vertical box for lock protection. The flexible vertical anti-seepage membrane is constructed in sections. After the first anti-seepage unit is constructed, its lock 7 is exposed to the disordered disturbance turbulence of mud and rock and soil debris. In order to prevent the lock 7 of the first anti-seepage unit 1 from being blocked when the unit to be excavated 2 is excavated, a self-clamping vertical box for lock protection is specially designed.

[0028] The self-clamping vertical box is composed of channel steel A3, channel steel B4, current wire A5, current wire B6, rotating part 8, flange A9, flange B10 and power supply battery 11; the openings of channel steel A3 and channel steel B4 are arranged opposite to each other and one side is hinged by rotating part 8, and the arrangement of rotating part 8 can facilitate the channel steel A3 and channel steel B4 to realize rotation and opening under the action of Ampere force. The full interface of channel steel A3 and channel steel B4 is of equal thickness, and the dimensions of channel steel A3 and channel steel B4 are: height (180 mm to 240 mm) × leg width (90 mm to 120 mm) × waist thickness (10 mm to 18 mm). The dimensions of channel steel A3 and channel steel B4 can be adjusted within the above range, but the proportion must be ensured. The ends of channel steel A3 and channel steel B4 (corresponding to the other end of rotating part 8) need to be punched in advance, and the punched hole diameter should be larger than the diameter of the current wire A5 and current wire B6 buried later. After the drilling is completed, the current conductor A5 and the current conductor B6 are buried in the vertical through-holes of the channel steel A3 and the channel steel B4. The current conductors must be completely insulated. The cross-sectional area of ​​the current conductor A5 and the current conductor B6 is 25 square millimeters to 60 square millimeters. The steel flange A9 and the flange B10 are welded at the ends of the channel steel A3 and the channel steel B4 (corresponding to the other end of the rotating part 8) to increase the clamping area and prevent accidental force from causing physical damage to the membrane body. The dimensions of the steel flange A9 and the flange B10 are: width: (30 mm to 50 mm) × thickness: (8 mm to 15 mm), and the upper and lower through-length spot welding is arranged. When the current conductor A5 and the current conductor B6 are energized, in order to better protect the membrane body, the steel flange A9 and the flange B10 are fully coated with epoxy resin on the contact surface with the high-density polyethylene membrane. Furthermore, the top of the current wire A5 and the current wire B6 are connected to the positive electrode of the power supply battery 11 through the positive wire 12, and the bottom of the current wire A5 and the current wire B6 are connected to the negative electrode of the power supply battery 11 through the negative wire 13, ensuring that the current directions of the current wire A5 and the current wire B6 are consistent.

[0029] After the construction of the first width anti-seepage unit 1 is completed, the vertical box is hoisted by a crane and installed to the depth of the membrane body; after the positive and negative pole wires are installed, power is turned on, and the ends of the channel steel A3 and the channel steel B4 are displaced toward each other under the action of the Ampere force of the magnetic field, driving the steel flange A9 and the flange B10 to stick to both sides of the high-density polyethylene membrane, isolating the debris generated by the rock and soil layer 14 of the channel wall, and protecting the lock 7 of the first width anti-seepage unit 1.
