A kind of concrete anti-seepage wall water-stop installation equipment

Abstract

This invention relates to a concrete anti-seepage wall water-stopping installation device, comprising a joint pipe body, a movable body, and a water-stopping plate. The side wall of the joint pipe body has a movable groove, and the movable body is embedded within the movable groove. The water-stopping plate is partially installed on the movable body. Because the movable body is embedded within the movable groove of the joint pipe body, when the pipe is pulled out by a pipe-pulling machine after the concrete has initially set, the movable body moves into the joint pipe body, causing the movable groove of the joint pipe body to lose support, thereby narrowing the opening and reducing the overall size of the joint pipe body for easier pipe pulling. Simultaneously, the movement of the movable body into the joint pipe body causes it to detach from the water-stopping plate, leaving the water-stopping plate at the joint of the concrete anti-seepage wall to achieve a water-stopping effect.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a water-stopping installation device for a concrete anti-seepage wall. Background Art

[0002] At present, with the vigorous development of my country's construction market, underground continuous walls are increasingly widely used as maintenance structures in large-scale deep foundation projects such as subways and housing construction. The underground continuous wall is composed of many wall sections. In order to maintain continuous construction between wall sections, the joints adopt the joint pipe process, that is, before pouring the groove section concrete, a joint pipe with a diameter equal to the groove width is pre-inserted at the end of the groove section. After the concrete is initially set, the joint pipe is slowly pulled out by the pipe pulling machine to form a semi-tenon-shaped joint at the end of the concrete. Then the convex mouth of the steel cage of the lower ground wall is lowered and connected, and then concrete is poured to form the two ground walls as a whole.

[0003] The above is a traditional construction method, which has certain disadvantages. First, there is a huge risk when pulling out the pipe. If the timing of pulling out the pipe is not mastered, the joint pipe will not be pulled out, causing an accident. Secondly, the wall joints sometimes leak water. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the joint pipe is difficult to be pulled out, which may easily cause an accident, and the wall joint part may sometimes be water-permeable.

[0005] In order to solve the above technical problems, the present invention provides a concrete anti-seepage wall water-stopping installation device, including a joint pipe body, a movable body and a water-stop plate. The side wall of the joint pipe body is provided with a movable groove, the movable body is embedded in the movable groove, and the water-stop plate is partially installed on the movable body.

[0006] Furthermore, the movable body moves relative to the movable groove through a driving device.

[0007] Furthermore, the driving device adopts two groups of oil cylinders, one end of the cylinder body of the oil cylinder is connected to the inner wall of the joint pipe body, one end of the telescopic rod of the oil cylinder is connected to the movable body, and the two groups of oil cylinders are symmetrically arranged up and down.

[0008] Furthermore, the cross section of the movable body is trapezoidal, and the upper bottom surface of the trapezoid is matched with the outer arc of the joint pipe body.

[0009] Furthermore, the shape of the movable groove matches the shape of the movable body.

[0010] Furthermore, the lower bottom surface of the trapezoidal cross section of the movable body is provided with limiting plates protruding toward both sides.

[0011] Furthermore, the movable body is provided with a mounting opening for accommodating the water stop plate.

[0012] Furthermore, the width of the installation opening matches the width of the water stop plate.

[0013] Furthermore, the depth of the installation opening is half the length of the water stop plate.

[0014] Furthermore, the water stop plate adopts a steel plate rubber water stop strip.

[0015] The above technical solution of the present invention has the following advantages: the movable body is embedded in the movable groove of the joint pipe body, and when the pipe is pulled out by the pipe pulling machine after the initial setting of the concrete, the movable body moves into the joint pipe body, so that the movable groove of the joint pipe body loses support, thereby shrinking the mouth, reducing the outer dimensions of the joint pipe body, and facilitating the pulling of the pipe;

[0016] At the same time, the movable body moves into the joint pipe body to separate the movable body from the water stop plate, leaving the water stop plate at the joint of the concrete anti-seepage wall, and then the protrusion of the steel cage of the lower ground wall is lowered and connected, and then concrete is poured to form the two ground walls as a whole. No matter how the gap between two adjacent ground walls is, the water stop plate forms a water retaining structure between the two, which can effectively prevent water seepage at the joints of the adjacent ground walls.

[0021] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] In the description of the present invention, it is necessary to understand that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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.

[0024] In the embodiment, a concrete anti-seepage wall water-stopping installation device is provided, comprising a joint pipe body 1, a movable body 2 and a water-stopping plate 3. The materials of the joint pipe body 1 and the movable body 2 can be metal or alloy materials, such as steel, and are formed by processing and welding steel. The side wall of the joint pipe body 1 is provided with a movable groove 4, and the movable body 2 is embedded in the movable groove 4, and through the embedding of the movable body 2, the movable groove 4 is expanded outward, thereby increasing the external dimensions of the joint pipe body 1.

[0025] When the pipe pulling machine is used to pull the pipe after the initial setting of the concrete, the movable body 2 will be separated from the movable groove 4, so that the movable groove 4 of the joint pipe body 1 loses support, thereby shrinking the joint pipe body 1 to reduce the outer dimensions of the joint pipe body 1 and facilitate pipe pulling.

[0026] The water stop plate 3 is partially installed on the movable body 2. Since the other part of the water stop plate 3 is combined with the initial setting concrete, when the movable body 2 is separated from the movable groove 4, the water stop plate 3 will also be separated from the movable body 2, leaving the water stop plate 3 at the joint of the concrete anti-seepage wall, and then the protrusion of the steel cage of the lower ground wall is lowered and connected, and then concrete is poured to make the two ground walls form a whole. No matter how the gap between two adjacent ground walls is, the water stop plate 3 forms a water retaining structure between the two, which can effectively prevent water seepage at the joints of adjacent ground walls.

[0027] In some embodiments, the movable body 2 moves relative to the movable groove 4 through a driving device, wherein the driving device is not limited to the cylinder 5, and a driving device such as a cylinder or an electric telescopic rod can also be used to move the movable body 2 into the joint pipe body 1.

[0028] In some embodiments, the driving device uses two groups of oil cylinders 5, one end of the cylinder body of the oil cylinder 5 is connected to the inner wall of the joint pipe body 1, and one end of the telescopic rod of the oil cylinder 5 is connected to the movable body 2. The two groups of oil cylinders 5 are symmetrically arranged up and down, so that the force on the movable body 2 is balanced and the movement is smoother. Of course, the number of the oil cylinders 5 is not limited to two groups, and can be increased or decreased according to actual conditions. The movable body 2 moves into the joint pipe body 1 or moves out of the joint pipe body 1 through the synchronous extension and contraction of the oil cylinders 5.

[0029] In some embodiments, the cross-section of the movable body 2 is trapezoidal, and the upper bottom surface of the trapezoid matches the outer arc of the joint pipe body 1. When the movable body 2 moves outside the joint pipe body 1 to the extreme position, the outer contour of the movable body 2 and the joint pipe body 1 is exactly a full circle.

[0030] In some embodiments, the shape of the movable groove 4 matches the shape of the movable body 2, that is, the inclination of the groove wall of the movable groove 4 matches the inclination of the waist of the trapezoidal cross-section of the movable body 2. When the movable body 2 moves to the extreme position outside the joint pipe body 1, the movable body 2 is completely fitted with the groove wall of the movable groove 4, so that the movable groove 4 expands outward, thereby increasing the external dimensions of the joint pipe body 1.

[0031] In some embodiments, the lower bottom surface of the trapezoidal cross-section of the movable body 2 is provided with a limit plate 6 protruding on both sides. When the movable body 2 moves outside the joint pipe body 1 to the extreme position, the limit plate 6 abuts against the inner wall of the joint pipe body 1, thereby preventing the cylinder 5 from being pushed out too far.

[0032] In some embodiments, the movable body 2 is provided with a mounting opening 7 for accommodating the water stop plate 3 , and the water stop plate 3 is connected to the movable body 2 by being partially embedded in the mounting opening 7 .

[0033] In some embodiments, the width of the mounting opening 7 matches the width of the water stop plate 3. Specifically, the width of the mounting opening 7 may be slightly narrower than the width of the water stop plate 3. Since the water stop plate 3 has a certain elasticity, it can be inserted into the mounting opening 7 to avoid falling out.

[0034] In some embodiments, the depth of the installation opening 7 is half the length of the water stop plate 3, half of the water stop plate 3 is embedded in the installation opening 7, and the other half is embedded in the concrete. When the pipe pulling operation is performed by the pipe pulling machine after the initial setting of the concrete, the movable body 2 will be separated from the movable groove 4, and the water stop plate 3 will also be separated from the movable body 2, leaving the water stop plate 3 at the joint of the concrete anti-seepage wall, and then the protrusion of the steel cage of the lower ground wall is lowered and connected, and then concrete is poured to make the two ground walls form a whole. No matter how the gap between two adjacent ground walls is, the water stop plate 3 forms a water retaining structure between the two, which can effectively prevent water seepage at the joints of adjacent ground walls.

[0035] In some embodiments, the water stop plate 3 is made of a steel plate rubber water stop strip, which is made of natural rubber as the main raw material, and has a use temperature of (-35°C to 60°C). Natural rubber has the characteristics of high elasticity and compression deformation, and produces elastic deformation under various loads, thereby playing an effective role in tightening and sealing, preventing water leakage and seepage of the building structure, and reducing shock and buffering.

[0036] In order to make the stress of each part of the water stop belt even and reasonable, a layer of stainless steel plate is added to the middle rubber layer of the steel plate rubber water stop belt. There is a strong adhesion between the steel plate and the rubber. The anti-seepage performance of the structural deformation is enhanced, and at the same time, the water components can withstand greater tension and torsion, improving the waterproof effect. It also adopts a non-uniform thickness structure, which is divided into a strong area, a waterproof area, and an installation area. The contact surface is large when the template is clamped, which prevents dislocation, is convenient for fixing, and is easy to construct and install. It is suitable for high-pressure waterproofing, such as underground facility waterproofing and foundation engineering water stopping.

[0037] A construction method for a concrete anti-seepage wall water-stopping installation device, the specific steps are as follows:

[0038] (1) When placing the pipe pulling machine, the ground must be flat and placed securely;

[0039] (2) Place the hydraulic station in a suitable location. The hydraulic station should not be placed on vibrating objects.

[0040] (3) connecting the oil pipe between the hydraulic station and the pipe pulling machine, and connecting the oil pipe between the hydraulic station and the oil cylinder 5;

[0041] (4) Check whether the movable body 2 on the joint pipe body 1 is pushed outward and in place. If not, connect the corresponding oil pipes in sequence and start the hydraulic station to push the movable body 2 outward and into place;

[0042] (5) Install the water stop plate 3 on the movable body 2, and pre-insert the joint pipe body 1 at the end of the trough section before pouring the trough section concrete;

[0043] (6) Pour concrete and wait for it to solidify;

[0044] (7) After the concrete reaches initial setting, the hydraulic station is started, and the movable body 2 moves toward the inside of the joint pipe body 1, and the water stop plate 3 is separated from the movable body 2 and remains in the concrete;

[0045] (8) After the oil cylinder 5 reaches the contraction limit, the pressure on the pressure gauge will rise, indicating that the movable body 2 has reached the limit position of moving toward the inside of the joint pipe body 1;

[0046] (9) Start the pipe pulling machine to pull out the joint pipe body 1. Since the outer dimensions of the joint pipe body 1 are shrunk at this time, the gap between the joint pipe body 1 and the concrete structure is increased, and the pulling force is reduced, which facilitates the pulling out of the joint pipe body 1;

[0047] (10) Check the status of the water stop plate 3 in the concrete and keep records.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
