Description

Technical Field

[0001] The invention relates to the field of pipe jacking construction, and in particular to a water stopping device for a well in a pipe jacking construction hole. Background Art

[0002] With the development of cities, urban land resources are becoming increasingly scarce, and urban construction is increasingly dependent on the development of underground space. The application of pipe jacking technology has played an important role in urban pipeline construction. With the development of large-scale pipe jacking technology, pipe jacking technology has become an important construction method for urban pedestrian walkways and other facilities. However, pipe jacking is an underground project. The groundwater level in southern regions such as Shanghai is high, and the soil texture is relatively soft. Pipe jacking leakage always threatens the safety of pipe jacking construction. During the process of pipe jacking construction, leakage accidents at the joints of the pipe jacking receiving end are relatively common. Once leakage occurs, there is a high probability that the hole well needs to be backfilled, and even the entire pipe jacking needs to be recharged, causing great economic losses. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defect that water leakage easily occurs in the seam between the jacking pipe and the hole opening of the tunnel wall during the jacking pipe construction process, and to provide a water stopping device for the seam between the jacking pipe and the tunnel.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A water-stopping device for the seam between a top pipe and a well, wherein the top pipe is passed through the first well wall of the well, and the seam is formed between the top pipe and the wall surface of the first well wall; the feature of the water-stopping device for the seam between the top pipe and the well is that the water-stopping device comprises a water-stopping component, wherein the water-stopping component comprises a first sealing surface and a second sealing surface, wherein the first sealing surface of the water-stopping component is sealedly pressed on the surface of the top pipe, and the second sealing surface is sealedly pressed on the wall surface of the first well wall, and the water-stopping component isolates the seam from the outside. In this scheme, the water-stopping component isolates the seam from the outside, wherein the first sealing surface is pressed on the surface of the top pipe, and the second sealing surface is pressed on the wall surface of the first well wall, thereby preventing water leakage from occurring at the seam and the wall surface of the first well wall around the seam. The sealing of the water-stopping component with the first well wall and the top pipe is a surface seal, which has a better sealing effect. The water-stopping component isolates the seam from the outside, thereby preventing water leakage from occurring at the seam.

[0006] Preferably, the water-stop component is formed by enclosing at least two water-stop units, and the water-stop units are pressed against each other at the butt joint.

[0007] A plurality of water-stopping units are continuously arranged in the circumferential direction of the top pipe, and adjacent water-stopping units are pressed together to form a complete water-stopping component.

[0008] Preferably, the water stopping unit comprises:

[0009] A first sealing body, wherein the water stop unit is sealed with the top pipe through the first sealing body; the first sealing surface is generated after the first sealing bodies are enclosed; and,

[0010] A second sealing body, the water-stop unit is sealed with the wall surface of the first well wall through the second sealing body; the second sealing body is sealingly connected to the end of the first sealing body; the second sealing surface is generated after the second sealing bodies are enclosed.

[0011] The first sealing surface formed by the first sealing bodies is pressed against the top pipe surface, and the second sealing surface formed by the second sealing bodies seals the wall surface of the first well wall. The first sealing body and the second sealing body are made of rubber. When the first sealing body is pressed against the top pipe surface and the second sealing body is pressed against the wall surface of the first well wall, since the rubber material has a certain elasticity, when the sealing body is pressed against the sealing surface, the rubber can fill the uneven area between the top pipe surface and the first well wall, so that the actual contact area of ​​each sealing surface is larger, the fit is tighter, and the sealing effect is better.

[0012] Preferably, the water-stop unit also includes a first protective layer and a second protective layer, the second protective layer is fixed to the end of the first protective layer, the first sealing body is clamped between the first protective layer and the top pipe, and the second sealing body is clamped between the second protective layer and the wall surface of the first well wall.

[0013] The load is transferred to the corresponding first sealing body and second sealing body through the first protective layer and the second protective layer. During the transfer process, the point load is converted into a surface load through the first protective layer and the second protective layer and transferred to the first sealing body and the second sealing body, thereby avoiding the occurrence of stress concentration and making the load transfer more uniform. As a result, the acting force between the first sealing body and the top pipe, and between the second sealing body and the first well wall is more uniform, and the fit between them is more tight.

[0014] Preferably, the first sealing body is bonded to the first protective layer, and the second sealing body is bonded to the second protective layer.

[0015] By bonding the first sealing body and the first protective layer, and the second sealing body and the second protective layer, the first sealing body and the first protective layer become one, and the second sealing body and the second protective layer become one. When the water stop unit is pushed into the jacking pipe, since each sealing body and each protective layer are bonded together, there will be no problem of each sealing body hanging in the air and falling off due to no connection with surrounding parts.

[0016] Preferably, the seam water-stopping device between the top pipe and the tunnel also includes a supporting component, and both ends of the supporting component are respectively connected to the tunnel and the water-stopping unit through pins installed in the vertical direction, and the water-stopping unit is pressed by the supporting component onto the wall surface of the top pipe and the first tunnel wall.

[0017] The support component outputs linear motion to push the water-stop unit to be pressed against the top pipe and the wall of the first well wall. The tail of the support component is connected to the well through a pin, and the pin is installed in the vertical direction, that is, the axis of the pin is in the vertical direction. The support component can rotate in the horizontal plane around the pin installed in the vertical direction. The head of the support component is connected to the water-stop unit through a pin, and the pin is installed in the vertical direction. The water-stop unit can rotate in the horizontal plane around the pin. The rotation of the support component around the pin at the tail in the horizontal plane drives the water-stop unit to rotate in the horizontal plane. The water-stop unit can also rotate around the pin at the head of the support component, so that the water-stop unit can adjust its position and the angle between the water-stop unit and the top pipe in the horizontal plane, so that the water-stop unit can fit more closely to the surface of the top pipe and the wall of the first well wall, so that the water-stop effect is better.

[0018] Preferably, each of the water-stop units further comprises at least three first connecting seats of supporting components, the first connecting seats of supporting components are arranged at equal intervals along the circumference of the water-stop unit, the distances from the multiple first connecting seats of supporting components to the end faces of the water-stop units are the same, and the first connecting seats of supporting components are connected to the supporting components one-to-one.

[0019] By symmetrically distributing the first connection seat of the support component, the water stop unit is installed one-to-one with the support component through the first connection seat of the support component. The load of the support component can be distributed to multiple points of the water stop unit, so that the support component can evenly transfer the load to the water stop unit.

[0020] Preferably, the water-stop component is composed of two water-stop units, and the supporting components corresponding to the two water-stop units are symmetrically arranged relative to the top pipe.

[0021] The support components are symmetrically arranged on both sides of the top pipe, so that when the water-stopping units are pushed by the support components to press against the top pipe and the wall surface of the first well wall, the water-stopping units on both sides can be evenly stressed, that is, the direction of the combined external force on the water-stopping units on both sides points to the axial direction of the top pipe. This prevents the asymmetric stress on the water-stopping units on both sides from causing the pressing direction of the water-stopping units on both sides to deviate from the axial direction of the top pipe, resulting in reduced sealing effect and poor water-stopping effect.

[0022] Preferably, the seam water-stopping device between the top pipe and the tunnel also includes two support component frames, the support component frames are respectively fixed to the second well wall and the third well wall of the tunnel, and the support component is connected to the tunnel via the support component frames.

[0023] By arranging the support component frames on the second well wall and the third well wall respectively, the support component can be stably connected to the second well wall and the third well wall of the well through the support component frames.

[0024] Preferably, the support component frame comprises:

[0025] A pad, one pad is disposed on each wall surface of the second well wall and the third well wall; and,

[0026] At least three second connecting seats of the supporting components are fixedly connected to the pad, and the supporting components are connected to the second connecting seats of the supporting components in a one-to-one correspondence via pins.

[0027] By providing the pad and the second connecting seat of the support component, the support component can be connected to the pad, so as to avoid the support component directly acting on the well wall surface and causing stress concentration. The pad evenly transfers the recoil force of the support component to the well wall surface, thereby providing a stable working environment for the support component.

[0028] Preferably, the seam water-stopping device between the top pipe and the wellbore also includes a limiting component, which is connected to the support component frame, and is located above and below the support component and is used to limit the upward or downward movement of the support component.

[0029] The vertical movement of the supporting component is limited by setting limit components on the upper and lower parts of the supporting component. The supporting component can only be rotated and adjusted in the horizontal plane.

[0030] Preferably, the supporting component is a jack.

[0031] By using jacks as supporting components, mechanical automation operation is achieved.

[0032] Preferably, the well is a receiving well.

[0033] By setting a water-stopping device for the joint between the top pipe and the tunnel in the receiving well, the water-stopping unit is pressed against the joint between the top pipe and the tunnel using a supporting component to enclose a water-stopping component. The first sealing surface and the second sealing surface of the water-stopping component respectively seal the joint between the top pipe and the tunnel, thereby achieving the effect of water-stopping the joint between the top pipe and the tunnel.

[0034] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0035] The positive and progressive effects of the present invention are:

[0036] The water-stopping device for the joint between the jacking pipe and the tunnel of the present invention uses a supporting component to push the rubber gasket of the water-stopping component to fit tightly with part of the jacking pipe section and the tunnel wall, so that a closed sealing area is formed at the joint between the jacking pipe and the tunnel, thereby achieving the effect of water-stopping the joint.

[0062] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0063] like Figure 1 , Figure 2 and Figure 3 As shown, the water-stopping device for the joint between the jacking pipe and the tunnel in an embodiment of the present invention, the jacking pipe 9 is penetrated through the first well wall 6 of the tunnel 110, and a joint 100 is formed between the jacking pipe 9 and the wall surface of the first well wall 6, and the water-stopping device for the joint between the jacking pipe and the tunnel includes a water-stopping component 1, and the water-stopping component 1 includes a first sealing surface 111 and a second sealing surface 112. The first sealing surface 111 of the water-stopping component 1 is sealingly pressed onto the surface of the jacking pipe 9, and the second sealing surface 112 is sealingly pressed onto the wall surface of the first well wall 6, and the water-stopping component 1 isolates the joint 100 from the outside.

[0064] The water-stop component 1 is a component used for water-stopping in the water-stopping device for the joint between the top pipe and the well. The water-stop component 1 is subjected to load and is pressed against the surface of the top pipe 9 and the wall surface of the first well wall 6. The first sealing surface 111 of the water-stop component 1 is sealed and pressed against the surface of the top pipe 9, and the second sealing surface 112 of the water-stop component 1 is sealed and pressed against the wall surface of the first well wall 6. The first sealing surface 111 is a cylindrical surface, and the second sealing surface 112 is a toroidal surface. The axis of the first sealing surface 111 is perpendicular to the second sealing surface 112, and one end of the first sealing surface 111 is sealed and connected to the second sealing surface 112. Through the joint action of the two sealing surfaces, the water-stop component 1 seals and isolates the joint 100 between the top pipe 9 and the first well wall 6 from the outside world, thereby preventing water leakage at the joint 100.

[0065] The water-stop component 1 is formed by enclosing at least two water-stop units 11 , and the water-stop units 11 are pressed together at the joints to form the water-stop component 1 .

[0066] Figure 1-3 The water-stop component 1 is illustrated as being composed of two water-stop units 11. Of course, in other embodiments, the number of water-stop units 11 constituting the water-stop component 1 may exceed 2, for example, the number of water-stop units 11 may be 3 or 4.

[0067] like Figure 1 and Figure 3 As shown, each water-stopping unit 11 is in an unclosed state in a top view and a front view. At this time, each water-stopping unit 11 has not enclosed a complete water-stopping component 1, and each water-stopping unit 11 has not pressed the top pipe 9.

[0068] like Figure 2 As shown, each water-stop unit 11 is in a closed state, that is, each water-stop unit 11 is pressed against each other to enclose a complete water-stop component 1. Each water-stop unit 11 is pressed against the top pipe 9 and the wall surface of the first well wall 6, the first sealing surface 111 seals the top pipe 9, and the second sealing surface 112 seals the wall surface of the first well wall 6.

[0069] The water stop unit 11 comprises:

[0070] First sealing body 113, the water stop unit 11 is sealed with the top pipe 9 through the first sealing body 113; each first sealing body 113 is enclosed to form a first sealing surface 111; and,

[0071] The second sealing body 114 , the water-stop unit 11 is sealed with the wall surface of the first well wall 6 through the second sealing body 114 ; the second sealing body 114 is sealed and connected to the end of the first sealing body 113 ; the second sealing surface 112 is generated after the second sealing bodies 114 are enclosed.

[0072] The first sealing body 113 is a semicircular tube, and the second sealing body 114 is a semi-cylindrical torus. One end of the first sealing body 113 is sealed and connected to the second sealing body 114. When each water-stop unit 11 encloses a complete water-stop component 1, each first sealing body 113 encloses a circular tube, and the inner surface of the circular tube is the first sealing surface 111. The water-stop component 1 is sealed with the top pipe 9 through the first sealing body 113.

[0073] Each second sealing body 114 forms a cylindrical ring body. The end surface of the cylindrical ring body formed by the second sealing bodies 114 is the second sealing surface 112. The water stop component 1 is sealed with the wall surface of the first well wall 6 through the second sealing body 114.

[0074] The first sealing body 113 and the second sealing body 114 are both made of rubber. The first sealing body 113 is in close contact with the pipe joint of the top pipe 9, and the second sealing body 114 is in close contact with the first well wall 6. The first sealing body 113 and the second sealing body 114 work together to seal the joint 100 between the top pipe 9 and the first well wall 6 to prevent water leakage from the joint 100.

[0075] The water-stop unit 11 also includes a first protective layer 115 and a second protective layer 116. The second protective layer 116 is fixedly connected to the end of the first protective layer 115. The first sealing body 113 is sandwiched between the first protective layer 115 and the top pipe 9. The second sealing body 114 is sandwiched between the second protective layer 116 and the wall surface of the first well wall 6.

[0076] The first protective layer 115 is tubular, the second protective layer 116 is a cylindrical ring, and the second protective layer 116 is fixed to the end of the first protective layer 115. The first protective layer 115 and the second protective layer 116 are made of steel, and their main functions are to bear and transfer loads.

[0077] The first protective layer 115 and the first sealing body 113, the second protective layer 116 and the second sealing body 114 respectively constitute a semicircular annular water-stopping unit 11. After the water-stopping units 11 are enclosed, a complete circular water-stopping component 1 is formed. According to the shape of the top pipe 9 or a complete elliptical water-stopping component 1, the shape and size of the inner surface of the water-stopping component 1 are the same as the shape and size of the outer surface of the pipe section of the top pipe 9. At this time, the rubber water-stopping pad inside the water-stopping component 1 fits tightly with the outer surface of the pipe section of the top pipe 9, and the rubber water-stopping pad against the well wall fits tightly with the surface of the well wall. The two fitted surfaces enclose the joint 100 between the top pipe 9 pipe section and the well wall into a closed state.

[0078] The first protective layer 115 and the second protective layer 116 transfer the driving force to the first sealing body 113 and the second sealing body 114. The first protective layer 115 and the second protective layer 116 increase the contact area between each protective layer and each sealing body, so that the load can be transmitted more evenly and stress concentration can be avoided. The larger contact area also makes the first sealing body 113 and the top pipe 9, and the second sealing body 114 and the wall surface of the first well wall 6 fit more closely, achieving a better sealing and water-stopping effect.

[0079] The first sealing body is bonded to the first protective layer, and the second sealing body is bonded to the second protective layer.

[0080] By bonding the first sealing body 113 and the first protective layer 115, and the second sealing body 114 and the second protective layer 116, the first sealing body 113 and the first protective layer 115 become one, and the second sealing body 114 and the second protective layer 116 become one. When the water-stopping unit 11 is pushed into the top pipe 9, the load is transferred to its corresponding sealing body through the protective layer, which prevents the sealing body from falling off due to being suspended in the air. The sealing bodies and the protective layers are connected together by bonding, and the problem of the sealing bodies falling off due to being suspended in the air without connection with the surrounding parts will not occur. The seam water-stopping device between the top pipe and the well also includes a support component 2, and the two ends of the support component 2 are respectively connected to the well 110 and the water-stopping unit 11, and the water-stopping unit 11 is pressed by the support component 2 on the wall surface of the top pipe 9 and the first well wall 6.

[0081] The two ends of the support component 2 are respectively connected to the water stop unit 11 and the well 110 through the pin shaft 4 installed in the vertical direction. The support component 2 pushes the water stop unit 11 to press against the top pipe 9 and the wall surface of the first well wall 6 by outputting a linear load, so that the water stop component 1 can be tightly pressed against the surface of the top pipe 9 and the surface of the first well wall 6. The tail of the support component 2 is connected to the well 110 through the pin shaft 4, and the pin shaft 4 is installed in the vertical direction, that is, the axis of the pin shaft 4 is in the vertical direction, and the support component 2 can rotate around the pin shaft 4 in the horizontal plane. The head of the support component 2 is connected to the water stop unit 11 through the pin shaft 4, and the pin shaft 4 is installed in the vertical direction, and the water stop unit 11 can rotate around the pin shaft 4 in the horizontal plane. The support component 2 rotates around the pin shaft 4 at the tail in the horizontal plane, driving the water-stop unit 11 to rotate in the horizontal plane. The water-stop unit 11 can also rotate around the pin shaft 4 at the head of the support component 2, so that the water-stop unit 11 can adjust the position and the angle between the water-stop unit 11 and the top pipe 9 in the horizontal plane, so that the water-stop unit 11 can fit more closely to the surface of the top pipe 9 and the wall of the first well wall 6, thereby improving the water-stopping effect.

[0082] Each water-stop unit 11 also includes at least three supporting component first connecting seats 117, which are arranged at equal intervals along the circumference of the water-stop unit 11, and the distances from multiple supporting component first connecting seats 117 to the end face of the water-stop unit 11 are the same. The supporting component first connecting seats 117 are connected to the supporting components 2 one by one.

[0083] Each water-stop unit 11 is connected to three support components 2. Three support component first connection seats 117 are installed on the outer surface of each water-stop unit 11, and each support component first connection seat 117 is connected to a support component 2 one by one. The number of support components 2 corresponding to each water-stop unit 11 is determined according to the size of the water-stop unit 11. If the size of the top pipe 9 is larger, the corresponding size of the water-stop unit 11 is also larger, and the number of support components 2 corresponding to each water-stop unit 11 can be increased. The three support component first connection seats 117 are distributed at equal intervals around the water-stop unit 11. The end face distances of the three support components 2 to the water-stop unit 11 are the same. The support component 2 is connected to the support component first mounting seat on the water-stop unit 11 through the pin 4.

[0084] The water-stop component 1 is composed of two water-stop units 11 , and the supporting components 2 corresponding to the two water-stop units 11 are symmetrically arranged relative to the top pipe 9 .

[0085] The support components 2 are symmetrically arranged on both sides of the top pipe 9. The support components 2 located on both sides of the top pipe push the water-stop units 11 to enclose the top pipe surface. The two water-stop units 11 are pressed together at the connection to form a water-stop component 1. The symmetrically arranged support components 2 make the force on the water-stop units 11 on both sides uniform, preventing the water-stop component 1 formed by the water-stop units 11 on both sides from being unevenly stressed, and the direction of the combined external force on the water-stop component 1 is inconsistent with the axial direction of the top pipe 9, ensuring that the first sealing surface 111 of the water-stop component 1 can be sealed and pressed on the surface of the top pipe 9, and the second sealing surface 112 can be sealed and pressed on the wall of the first well wall 6, so as to achieve a good sealing and water-stopping effect.

[0086] The joint water-stopping device between the top pipe and the cavern 110 also includes two support component frames 3 , which are respectively fixed to the second well wall 7 and the third well wall 8 of the cavern 110 , and the support component 2 is connected to the cavern 110 via the support component frames 3 .

[0087] The support component frame 3 is installed on the second well wall 7 and the third well wall 8 of the cave 110 , and the support component 2 is connected to the second well wall 7 and the third well wall 8 of the cave 110 by connecting the support component frame 3 .

[0088] The support component frame 3 includes a pad 32 and at least three support component second connecting seats 31. A pad 32 is arranged on the wall surface of the second well wall 7 and the third well wall 8. The support component second connecting seat 31 is fixedly connected to the pad 32. The support component 2 is connected to the support component second connecting seat 31 one by one through the pin shaft 4.

[0089] The pad 32 is made of steel. The tail of the support component 2 is connected to the second support component connection seat 31 on the pad 32 through the pin 4. The pad 32 is fixed to the well wall of the hole, and the support component 2 is connected to the second well wall 7 and the third well wall 8 of the hole 110 through the pad 32. The well wall body provides a recoil reaction force to the support component 2 through the pad 32. The support component 2 is connected to the well wall through the pad 32, so that the recoil point load of the support component 2 is converted into a surface load through the pad 32 and transmitted to the well wall surface, avoiding the support component 2 directly acting on the well wall to cause stress concentration. The support component frame 3 provides a stable working environment for the support component 2.

[0090] Limit rods are arranged at the upper and lower ends of the support component 2, and the support component 2 can move freely between the upper and lower limit rods.

[0091] The joint water-stopping device between the top pipe and the well also includes a limiting component 5, which is connected to the support component frame 3. The limiting component 5 limits the movement of the support component 2 in the vertical direction.

[0092] The limiting component 5 is an angle steel, and two angle steels are installed on the upper and lower sides of a support component 2. The limiting component 5 limits the vertical movement of the support component 2. The support component 2 is connected to the pad 32 through the pin 4. By installing the limiting component 5 on the upper and lower sides of the support component 2, the limiting component 5 below the support component plays the role of supporting the support component 2. The support component 2 is connected to the second connecting seat 31 of the support component on the pad 32 through the pin 4. The connecting piece at the tail of the support component 2 is provided with a through hole, and the second connecting seat 31 of the support component and the support component 2 are connected at the connection. The upper and lower surfaces of the U-shaped groove are provided with holes that match the through hole of the connecting piece at the tail of the support component 2. The connecting piece at the tail of the support component 2 is inserted into the U-shaped groove of the second connecting seat 31 of the support component, and the U-shaped groove is connected with the through hole of the connecting piece of the support component 2 by the pin 4. The axis of the through hole is in the vertical direction. Under the action of the limiting component 5, the vertical movement of the support component 2 is limited, and under the action of the pin shaft 4 installed in the vertical direction, the support component 2 can only rotate in the horizontal plane. Because the support component 2 can rotate freely in the horizontal plane, the jacking direction of the support component 2 is adjusted in the horizontal direction during use to accurately find the joint position of the hole 110 and the top pipe 9. The support component 2 supports the water-stopping unit 11 to be close to the joint of the hole 110 and the top pipe 9. By adjusting the jacking angle of the support component 2 in the horizontal direction, it is ensured that the water-stopping unit 11 can accurately seal the joint of the hole 110 and the top pipe 9, and achieve a good sealing and water-stopping effect.

[0093] The supporting component 2 is a jack. The water-stopping device for the joint between the top pipe and the well uses the jack as the power source, and realizes mechanical automation operation through the jack, eliminating a large number of manual operations. The jack is used as a supporting device. The jack pushes the rubber gasket formed by the two first sealing bodies 113 and the two second sealing bodies 114 through the first protective layer 115 and the second protective layer 116 to fit closely with the outer wall of the pipe section of the top pipe 9 and the first well wall 6 to form a closed sealing area, thereby achieving the effect of water stopping.

[0094] The well 110 is a receiving well.
