Abstract
Description
Technical Field
[0001] This application relates to the field of water-stopping in areas such as foundation pits, slopes, rivers, dams, mines, wharves, and shorelines, and is particularly applicable to foundation pit support and slope engineering. Background Technology
[0002] Currently, most water-stopping curtain projects for foundation pits or slopes worldwide adopt rigid water-stopping systems such as mixing piles, jet grouting piles, interlocking piles, and diaphragm walls. The core of these systems is to utilize the bonding effect of cement and soil and concrete to form a rigid water-stopping structure.
[0003] The characteristics of the above water-stopping system are:
[0004] 1. A large amount of cement needs to be added to the soil to form a cement-soil structure or concrete can be used to replace the original soil, which is costly and has low construction efficiency.
[0005] 2. The water-stop structure is implemented in sections or units. The connection effect between each water-stop unit is limited by verticality, layout accuracy, cement content and the construction level of the construction unit. The connection of each water-stop unit is a weak link, resulting in poor overall water-stop effect.
[0006] 3. The water-stopping effect within a single unit is also limited by the cement content, stratum properties, and groundwater conditions;
[0007] 4. The formed water-stopping structure is a rigid structure. When the foundation pit or slope undergoes large deformation, the water-stopping system will deform and crack, losing its water-stopping effect.
[0008] Therefore, conventional water-stopping systems have significant shortcomings. Even with some experimental techniques employing insertable membrane structures, they only solve the water-stopping problem within a single unit. The connection between multiple units is also difficult to address effectively, resulting in a poor overall water-stopping effect that is hard to meet the requirements of engineering implementation.
[0009] To address the shortcomings of conventional water-stopping systems, the search for a simple, integrated, low-cost, efficient, and reliable water-stopping system and construction method is a practical breakthrough direction for water-stopping in fields such as foundation pit support, slopes, rivers, dams, mines, wharves, and shorelines. Utility Model Content

[0022] In a preferred embodiment, the traction device is a power device that pulls the forward device along the direction of the water-stopping line on the ground to move it forward in the fluidized undisturbed soil mixing body and unfold the core membrane.
[0023] Furthermore, the traction-type continuous core membrane sealing system also includes a counterweight to prevent the forward device from floating, and a ground guide component if necessary.
[0024] This utility model also relates to a traction-type continuous core membrane water-stopping system, characterized in that it includes an undisturbed soil mixing body, a closed or long continuous core membrane that is erected in the undisturbed soil mixing body after implementation, and auxiliary components for sealing nodes.
[0025] Furthermore, the core membrane is a prefabricated membrane according to the water-stopping depth and long water-stopping length, and its material is a geotextile or polymer film material that meets the requirements of being impermeable, having a certain tensile strength, and having a certain shear strength.
[0026] Furthermore, the original soil mixture contains cement.
[0027] Furthermore, the auxiliary components are jet grouting piles, mixing piles, or grouting components.
[0028] A second aspect of the invention also relates to an implementation component of a traction-type continuous core membrane water-stopping system, comprising a core membrane, a housing containing an internal core membrane and a forward movement device, a forward movement device, an implantation device, a traction rope, and a traction device, wherein the housing is cylindrical with an opening on one side; the forward movement device is connected to the traction rope and the core membrane and is disposed adjacent to the opening, for traction of the core membrane to advance and unfold in the undisturbed soil mixing body.
[0029] Furthermore, the implementation component also includes an implantation device for implanting the cartridge into the undisturbed soil mixer and removing the cartridge after implantation.
[0030] In a preferred embodiment, the implementation components also include a traction device that uses a traction rope to pull the forward device and the core membrane out of the undisturbed soil mixing body.

[0042] Compared with existing waterproofing systems, the technical solution and preferred embodiments of this utility model have the following characteristics and beneficial effects:
[0043] 1. Excellent integrity, superb and fully controllable water-stopping effect. Because this system forms a closed or long-segment continuous impermeable core membrane after formation, its integrity and sealing performance are excellent. Furthermore, since this system relies on the closed, impermeable, flexible core membrane for water stoppage, it does not require the strength and rigidity of the mixing body. Moreover, the core membrane material is a factory-prefabricated material with high tensile and shear strength and is impermeable. Therefore, the water-stopping effect of this system is excellent and fully controllable, and its engineering feasibility is good.
[0044] 2. High construction efficiency. When this system is implemented, a long section of fluid undisturbed soil mixing body can be formed in one go, and a closed or long section of water-stopping core membrane can be formed in one go within the mixing body. At the same time, no cement needs to be added during implementation, making construction simple and extremely efficient.
[0045] 3. Low cost. This system only requires mixing the original soil to form a fluid soil mass, which is then inserted and unfolded to form a core membrane. No cement needs to be added during construction, resulting in a significant reduction in cost compared to traditional water-stopping structures.
[0046] 4. Wide range of applications. The traction-type continuous core membrane water-stopping system of this utility model is applicable to most strata, including conventional fill, silt, clay, sand, and gravel layers, and is not limited by groundwater conditions during implementation, making its application range extremely wide.
[0047] 5. Reliable quality of the water-stopping core membrane. The water-stopping core membrane of this utility model is a disposable factory prefabricated product. This core membrane has the characteristics of being impermeable, having high tensile strength, and high shear strength. It is not easily damaged during construction and use of the water-stopping system, and its quality is reliable.
[0048] 6. The traction-type continuous core membrane water-stopping system of this utility model is a flexible water-stopping system. Unlike traditional rigid water-stopping structures such as mixing piles, jet grouting piles, interlocking piles, and underground continuous walls, when there is a large displacement of the foundation pit or slope, even if the original soil mixing body cracks and is damaged, the water-stopping core membrane can still be used normally, and the water-stopping effect is not affected. It has excellent risk resistance and safety. Attached Figure Description
