For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0025] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] In the present invention, if Figures 1 to 5 As shown, a water intake pressure connection device is provided, comprising a fixed seat 1, a connecting ring 2 arranged on one side of the fixed seat 1, and a hydraulic cylinder 3 connected to the fixed seat 1, wherein a connecting portion is provided on a side of the fixed seat 1 away from the connecting ring 2, and the hydraulic cylinder 3 can be connected to the connecting ring 2 to drive the connecting ring 2 to move toward the fixed seat 1; the connecting ring 2 is provided with a plurality of top cones 4 at intervals along its circumferential direction on a side facing the fixed seat 1; the connection device also includes a connecting rope 5, and the connecting rope 5 can be connected to the fixed seat 1 and / or the connecting ring 2 and / or the hydraulic cylinder 3.

[0027] When the pressure connection device of the present invention is used, the following steps are performed with reference to the pressure connection method of the water intake provided by the present invention: S1. Confirm the opening area on the surface side of the water pipe, and open a connecting annular groove 10 at the edge of the opening area. The distance h1 between the bottom wall of the connecting annular groove 10 and the inner surface of the water pipe is greater than 3 cm and less than or equal to 6 cm. By controlling the distance h1, it is possible to prevent the opening area from falling off directly due to the connecting annular groove 10 being opened too deep, and it is also possible to reduce the difficulty of the cone rod 401 pushing in and damaging the bottom wall of the connecting annular groove 10.

[0028] S2, connect the fixing plate in the opening area, and insert the top cone 4 into the groove of the connecting ring 2; S3, installing a connecting pipe 16 in the opening area, the connecting pipe 16 is connected to the connecting ring groove 10, and the connecting rope 5 is led out to the outside of the connecting pipe 16; As shown in the figure, a water collection well 14 and a valve well 15 are set at the actual water intake point. A valve pipeline connected to the water collection well 14 is set in the valve well 15. One end of the connecting pipe 16 is connected to the connecting annular groove 10, and the other end is connected to the water collection well 14. The connecting rope 5 is led out from the water collection well 14. In this way, after the top cone 4 completes the operation of destroying the bottom wall of the connecting annular groove 10, the entire connecting device can be pulled out together with the damaged part of the pipeline in the opening area through the connecting rope 5. In this process, the water collection well 14 can receive the water led out by the connecting pipe 16, which can facilitate the operation.

[0029] S4, control the hydraulic cylinder 3 to drive the connecting ring 2 to move toward the fixing seat 1, and the top cone 4 destroys the bottom wall of the groove of the connecting ring 2; S5. Drag the water intake pressure connecting device out from the inside of the connecting pipe 16 through the connecting rope 5.

[0030] The connecting device of the present invention has the following effects when in use. First, the entire connecting device is fixed in the opening area to be removed when the connecting pipe 16 is not installed, which is convenient for installing the connecting device. There is no need to set a fixing structure of the connecting device in the connecting pipe 16. After the opening is completed, the concrete 13 in the opening area can be taken out together with the connecting device; second, the hydraulic cylinder 3 is used as the power structure to provide a larger bursting force, and the hydraulic pipeline can be led out from the connecting pipe 16, further simplifying the structure of the operating parts in the connecting pipe 16; third, multiple top cones 4 are used for top pressure destruction. Compared with the existing rotary cutting destruction method, the drive is simple, no heat dissipation is required, and the entire equipment structure is stable and easy to maintain.

[0031] In a preferred embodiment, for the structure of the present invention, further specifically, the top cone 4 includes a cone rod 401 and a cone tip 402 arranged at an end of the cone rod 401 away from the connecting ring 2, the size of the cone tip 402 in the circumferential direction of the connecting ring 2 is larger than the size of the cone member in the radial direction of the connecting ring 2, and the cross-sectional size of the cone member gradually increases in the direction toward the connecting ring 2.

[0032] As shown in the figure, the cone as a whole is in the shape of an ellipsoid extending laterally, so that during the jacking process of the cone, it is easier for the bottom wall of the connecting annular groove 10 to produce circumferential cracks (affected by the circumferential extrusion and expansion stress of the connecting annular groove 10 at the position of the cone), and it is easier for the cracks in the ruptured areas of the adjacent top cones 4 to develop and penetrate, so that the bottom wall of the connecting annular groove 10 as a whole presents a "smooth blasting" form of crack development and cutting, which can further reduce the difficulty of separating the water pipe part on the inner side of the connecting annular groove 10.

[0033] In the illustrated embodiment, the connecting rope is connected to the hydraulic cylinder, which is not intended to be a limitation of the present invention. In an optional embodiment, the connecting rope may also be fixed to a connecting ring or a fixing seat.

[0034] In a preferred embodiment, for the structure of the present invention, to be more specific, the outer edge of the connecting ring 2 is provided with a guide arc plate 6, and the guide arc plate 6 extends inwardly in a direction away from the mounting seat.

[0035] As shown in the figure, by providing a guide arc plate 6, when the entire connecting device is dragged outward, the dragging resistance can be reduced by using the guide arc plate 6. In the embodiment shown in the figure, two guide arc plates are provided (one is removed to better show the structure), the connecting ring is provided with a fixing block, and the guide arc plate is connected to the fixing block by screws.

[0036] In a preferred embodiment, for the structure of the present invention, more specifically, the connecting ring 2 is provided with a through hole for the hydraulic cylinder 3 to pass through, and one end of the hydraulic cylinder 3 is connected to the fixing seat 1 .

[0037] As shown in the figure, the hydraulic cylinder 3 can be arranged in the space on the side of the connecting ring 2 away from the fixed seat 1, thereby shortening the distance between the connecting ring 2 and the mounting seat, so as to further reduce the length requirement of the top cone 4, thereby reducing the ultimate bending moment generated during the insertion process of the top cone 4, and further improving the stability of the top cone 4.

[0038] In the embodiment shown in the figure, the length optimization of the top cone 4 is exemplarily described. After the entire connecting device is installed in the water pipe, the tip of the top cone 4 abuts against the bottom wall of the connecting ring groove 10, and the stroke required by the top cone 4 is approximately (h1-2) cm to (h1+2 cm), that is, the maximum stroke of the connecting ring 2 is about 8 cm. At this time, the distance between the connecting ring 2 and the fixing seat 1 can meet the stroke of the top cone 4. The present invention can make the initial position of the connecting ring 2 only meet its stroke by passing the hydraulic cylinder 3 through the connecting ring 2, without considering the installation space of the hydraulic cylinder 3.

[0039] In a preferred embodiment, for the structure of the present invention, to be more specific, the inner rod section of the hydraulic cylinder 3 is connected to the fixing seat 1, the sleeve section is connected to the side of the connecting ring 2 away from the fixing seat 1, and the inner rod section passes through the through hole. As shown in the figure, the present invention can push the connecting ring 2 toward the fixing seat 1 by connecting the sleeve section to the surface side of the connecting ring 2, thereby reducing the distance between the top cone 4 and the pushed position of the connecting ring 2, thereby reducing the bending moment generated in the process of the connecting ring 2 transmitting the top pressure moment, thereby preventing the connecting ring 2 from being deformed by the top pressure.

[0040] In a preferred embodiment, for the structure of the present invention, more specifically, the sleeve section of the hydraulic cylinder 3 forms a plurality of limiting protrusions 7 at intervals along its circumference, and the connecting ring 2 is provided with a notch 8 for the limiting protrusion 7 to pass through, and when the connecting ring 2 moves to the side where the limiting protrusion 7 is facing the fixed seat 1, the limiting protrusion 7 can abut against the portion of the connecting ring 2 outside the notch 8.

[0041] As shown in the figure, the detachable connection between the connecting ring 2 and the hydraulic cylinder 3 can be achieved. When the fixing seat 1 needs to be connected to the surface side of the water pipe, the connecting ring 2 can be removed first, and the fixing seat 1 can be conveniently connected to the water pipe at this time to reduce the interference of the top cone 4 on the installation and fixing process. After the fixing seat 1 is installed, the connecting ring 2 can be moved toward the fixing seat 1, and the limiting protrusion 7 passes through the notch 8, and then the connecting ring 2 is rotated so that the limiting protrusion 7 is pressed on the connecting ring 2 to complete the installation.

[0042] In a preferred embodiment, for the connection of the fixing seat 1, expansion bolts can be installed on the surface side of the water pipe, and the fixing seat 1 can be installed by using the expansion bolts.

[0043] In a preferred embodiment, for the structure of the present invention, to be more specific, the connection ring 2 is provided with a limiting convex edge 9 at a position at the edge of the notch 8 on a surface away from the fixing seat 1 .

[0044] As shown in the figure, by setting the limiting protrusion 7, the position of the limiting protrusion 7 and the connecting ring 2 can be positioned to prevent the limiting protrusion 7 from entering the notch 8 due to the free rotation of the connecting ring 2 when the hydraulic cylinder 3 drives the connecting ring 2 to move.

[0045] In the illustrated embodiment, a detachable connection is adopted between the connecting ring 2 and the hydraulic cylinder 3, which is not the structure of the hydraulic cylinder 3 and the connecting ring 2 of the present invention. Now in an optional embodiment, the connecting ring 2 and the hydraulic cylinder 3 may also be fixedly connected, such as by welding or bolting the connecting ring 2 and the hydraulic cylinder 3.

[0046] The structure of the top cone 4 is not limited to the flat plate structure shown in the figure, and in an optional embodiment, a conical structure may also be adopted.

[0047] The present invention also provides a water intake pressure connection method, including the water intake pressure connection device as described above, and the connection method includes: S1. Confirm the opening area on the surface of the water pipe, and open a connecting annular groove 10 at the edge of the opening area. The distance between the bottom wall of the connecting annular groove 10 and the inner surface of the water pipe is h1, and h1 is greater than 3 cm and less than or equal to 6 cm; S2, connect the fixing plate in the opening area, and insert the top cone 4 into the groove of the connecting ring 2; S3, installing a connecting pipe 16 in the opening area, the connecting pipe 16 is connected to the connecting ring groove 10, and the connecting rope 5 is led out to the outside of the connecting pipe 16; S4, control the hydraulic cylinder 3 to drive the connecting ring 2 to move toward the fixing seat 1, and the top cone 4 destroys the bottom wall of the groove of the connecting ring 2; S5. Drag the water intake pressure connecting device out from the inside of the connecting pipe 16 through the connecting rope 5.

[0048] In a preferred embodiment, for the method of the present invention, to be more specific, the forming of the connecting annular groove 10 at the edge of the opening area in S1 also includes drilling a hole in the bottom wall of the connecting annular groove 10 to form a socket 11 for inserting the cone tip 402 of the top cone 4.

[0049] As shown in the figure, by providing the insertion hole 11, the cone tip 402 of the top cone 4 can be partially inserted into the insertion hole 11, so that in the further jacking process of the top cone 4, the top cone 4 can directly produce extrusion damage at the position of the insertion hole 11, making it easier to produce through cracks between each insertion hole 11, so that the opening area and the water pipe can be quickly separated by the development of cracks connected between adjacent insertion holes 11. This method of the present invention is particularly suitable for the flat plate-shaped cone structure of the top cone 4 in the illustrated embodiment. The top cone 4 gradually applies axial extrusion stress to the hole wall of the drilled hole during the jacking process, and can quickly produce cracks in the circumferential direction of the bottom wall of the groove of the connecting ring 2.

[0050] Preferably, the distance between the bottom wall of the plug hole 11 and the inner surface of the water pipe is controlled to be more than 1 cm, so as to prevent water leakage caused by drilling through the plug hole 11 and facilitate connection through the position of the plug hole 11 when circumferential cracks are generated in the connecting annular groove 10 during the insertion of the cone tip 402.

[0051] In a preferred embodiment, for the method of the present invention, more specifically, installing the connecting pipe 16 in the opening area includes: implanting the connecting rib 12 outside the connecting ring groove 10 on the surface side of the water pipe; inserting the connecting pipe 16 into the connecting ring groove 10; pouring concrete 13 outside the connecting pipe 16. As shown in the figure, the fixing stability of the connecting pipe 16 can be increased. Regarding the sealing of the installation of the connecting pipe 16, a sealing structure such as a waterproof roll material and a sealing filler can be applied at the position where the connecting pipe 16 is inserted into the connecting ring 2 groove.

[0052] It should be noted that the present invention Figure 1 In order to better display the structure, some guide arc plates are removed.

[0053] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0054] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
