Description

Technical Field

[0001] The present invention belongs to the field of underground pipelines and inspection wells, and specifically, relates to an assembled inspection well pipeline construction method and a construction device; more specifically, relates to an assembled inspection well socket-type flexible joint and a pipeline connection method thereof. Background Art

[0002] Underground pipelines are pipes laid underground for the transportation of liquids, gases or loose solids. Inspection wells are usually set up for underground pipelines for the convenience of maintenance and installation. Inspection wells are generally set up at the intersection of pipelines, bends, and a certain distance on straight pipe sections. They are auxiliary structures that are convenient for regular inspections.

[0003] The inspection well includes a well chamber, which is connected to a pipe, which is communicated with the inside of the well chamber. The connection between the pipe and the well chamber is generally a rigid connection, that is, a socket is opened on the side wall of the well chamber, and the end of the pipe is inserted into the side wall of the well chamber. Cement mortar is applied to the gap at the connection between the pipe and the well chamber for sealing. After the applied cement mortar solidifies, the well chamber is sealed to complete the setting of the inspection well.

[0004] The assembled inspection well is a well chamber that is cast in one piece, and its connection with the pipeline is a rigid tape interface construction method. This rigid interface connection method has certain defects: First, the uneven deformation of the inspection well body foundation and the pipeline foundation may cause ground subsidence, especially the drainage pipeline, causing the rigid interface to crack and leak, resulting in soil erosion and ground subsidence. Safety hazards. Second, the cement mortar has a poor sealing effect on the connection position, which is prone to water seepage, causing ground subsidence and damage to the connection position between the pipeline and the well chamber. In addition, the end of the pipeline is inserted into the side wall of the well chamber, and cement mortar is applied to the gap between the pipeline and the well chamber for sealing. In this case, when the soil layer deformation phenomenon such as geological settlement occurs, the deformation of the soil layer causes the pipe and the well body to rotate or loosen slightly, which will cause the sealing of the pipe and the well body to decrease, and easily cause the fluid in the pipe to leak. Moreover, once the connection between the pipe and the well body starts to rotate or loosen, the gap between the two connections will become larger, and even cause the two to separate. Third, the rigid interface is a pipeline interface that cannot withstand a certain amount of axial displacement and relative angular displacement. Fourth, the pipelines and inspection wells are all prefabricated and assembled, and the interfaces are cast-in-place or sealed with mortar. They are wet operations, with the defects of many construction steps, long installation time, and inconsistent installation technology. Summary of the invention

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

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

[0050] 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.

[0051] Please also read Figures 1 to 8Now, a method for constructing a prefabricated inspection well pipeline provided by the present invention is described. The method for constructing a prefabricated inspection well pipeline comprises the following steps:

[0052] S1. Casting the inspection well chamber. The inspection well chamber is prefabricated with reserved holes for connecting with pipelines. The types of reserved holes include socket holes 102 and trumpet-shaped sockets 101.

[0053] In this step, the inspection well chamber is formed by pouring precast concrete. The shape of the inspection well chamber can be rectangular or circular. The inspection well chamber is provided with a plurality of reserved openings. Specifically, reserved openings connected to the pipeline are prefabricated on any two or three sides of the inspection well chamber. More specifically, the reserved openings of the inspection well chamber are provided with two types. One is a socket opening 102, and the other is a trumpet-shaped socket 101.

[0054] A certain range of protruding concrete is provided on the outer surface around each reserved hole to make up for the wall thickness of the well chamber at that location and meet the strength requirements for retaining the socket or spigot within this range;

[0055] The outer surface around the well chamber at the socket hole presents a certain range of protruding structures. The setting of the protruding structure can make up for the defects of no interface plane or / and insufficient well wall thickness, and can also be applied to circular inspection wells.

[0056] The outer diameter of the socket hole 102 is larger than the outer diameter of the pipe.

[0057] The inner wall surface of the reserved hole is provided with an annular groove for accommodating the sealing ring. There are at least two annular grooves. For example, there are 2, 3, or 5 annular grooves.

[0058] The socket part is prefabricated into a socket end that is completely consistent with the socket form and size tolerance of the pipe, which is convenient for construction.

[0059] S2, the pipe is connected to the reserved hole of the socket hole type;

[0060] In this step, the connection structure between the reserved hole of the socket hole type and the pipeline is: the socket hole 102 is in sealing contact with the second concrete bell-and-spigot pipe 6 through the second sealing ring 9. Specifically, the second sealing ring sleeve 9 is arranged on the second concrete bell-and-spigot pipe 6. When the second concrete bell-and-spigot pipe 6 is inserted into the socket hole 102, the second sealing ring 9 located in the annular groove is squeezed by force to generate elastic compression, thereby achieving sealing contact with the second concrete bell-and-spigot pipe 6. Among them, the diameter of the second sealing ring 9 is larger than the outer diameter of the pipeline.

[0061] The sealing method adopted in this method is: the outer wall of the second concrete bell-and-spigot pipe 6 is polished to make the pipe round, and its outer wall is used as a sealing interface without specially making a pipe mouth, which is convenient for construction.

[0062] In this step, the construction process of the socket connection is: sawing the pipe → grinding the pipe mouth → installing the rubber ring → applying oil (wax) to the pipe body → pulling back the impact mouth → filling the sand base.

[0063] Specifically, the following steps are included:

[0064] Determine the installation length of the last section of the pipe and the reserved hole in the inspection well according to the on-site conditions, mark the cutting position on the pipe to be cut with a label or a marker, place the pipe cutting tool on the pipe to be cut, and start cutting.

[0065] After cutting, remove any debris or debris from the pipe. Check whether the cut is smooth. If it is not smooth, you can use auxiliary tools such as files to trim and polish it.

[0066] Select the appropriate rubber ring according to the pipe diameter, insert the rubber ring close to the outer wall of the cut, and then apply lubricant evenly on the rubber ring and the inside of the inspection well socket. Remove dust from the surface of the pipe, apply oil or paraffin as lubricant to the outer wall of the pipe to reduce the friction resistance of the pull-back.

[0067] Pull the second concrete spigot and socket pipe 6 into place, insert it into the assembled inspection well socket, and level the socket. Then pull the socket of the third concrete spigot and socket pipe 7 synchronously and insert it into the other end of the second concrete spigot and socket pipe 6. Pull slowly and check at any time. Stick to the socket wall so that the rubber ring rolls into the socket evenly in one direction in sequence, and the other end rolls into the assembled inspection well socket. The socket push-in position should meet the requirements, so that the rubber sealing ring is correctly in place without distortion or falling off. After installation, insert a probe into the gap to determine whether the rubber ring is in the correct position and there is no distortion.

[0068] The bottom of the pipes entering and exiting the wellhead is filled with medium sand, leaving no gaps.

[0069] S3. The pipe is connected to the reserved hole of the trumpet-shaped socket type;

[0070] The reserved hole of the trumpet-shaped socket type is compatible with the socket structure provided at one end of the first concrete bell-and-spigot pipe 5. That is, the reserved hole of the trumpet-shaped socket type is consistent with the technical requirements of the socket structure provided at one end of the first concrete bell-and-spigot pipe 5, which can facilitate construction. The construction process is: the trumpet-shaped socket 101 is in sealing contact with the first concrete bell-and-spigot pipe 5 through the first sealing ring 8. Specifically, the first sealing ring sleeve 8 is arranged on the first concrete bell-and-spigot pipe 5. When the first concrete bell-and-spigot pipe 5 is inserted into the trumpet-shaped socket 101, the first sealing ring 8 is squeezed by force to produce elastic compression, thereby achieving sealing contact with the first concrete bell-and-spigot pipe 5. Among them, the diameter of the first sealing ring 8 is larger than the outer diameter of the pipe.

[0071] This method of connecting the assembled inspection well pipe also includes: during construction, first fix the inspection well, and then connect the pipes from the downstream to the upstream in sequence. Insert the pipe with the elastic sealing ring into the reserved hole installation position of the inspection well, and achieve the sealing effect by squeezing the elastic sealing ring to achieve the tightness of the joint between the inspection well chamber and the pipe. The pipe connected to the inspection well chamber is cut according to the actual on-site measurement results to achieve the connection of drainage pipes of any length with the inspection well.

[0072] The elastic sealing ring is deformed, and the elastic sealing ring and the pipe are squeezed. After deformation, the elastic sealing ring is close to the inner wall of the reserved hole of the pipe and the inspection well chamber, which improves the sealing of the connection between the pipe and the inspection well chamber. It can effectively block water, and water cannot penetrate into the elastic sealing ring, thereby reducing erosion and leakage after long-term contact with water.

[0073] The diameter characteristics of the socket and spigot of the inspection well are: the outer diameter of the socket hole is a certain size larger than the outer diameter of the pipe; the socket part is prefabricated into a socket end with a size tolerance that is completely consistent with the socket inner and outer socket of the pipe.

[0074] The connection method between the inspection well chamber and the pipeline is to use a flexible interface, so that the connection part between the inspection well chamber and the pipeline can withstand greater uneven settlement deformation, which is beneficial to preventing leakage and increasing the life of the pipeline and the inspection well.

[0075] An assembled inspection well pipeline construction device, please refer to Figures 9 to 11 , comprising: a device body 1, a connecting rod 2 rotatably connected to the device body 1, a grinding assembly 3 connected to the connecting rod 2, and a monitoring assembly 4 connected to the connecting rod 2. The length of the connecting rod 2 is adjustable.

[0076] When installing the pipeline, the device body 1 is connected to the pipeline, and the connecting rod 2 rotates relative to the device body 1, driving the grinding component 3 in contact with the grinding surface of the pipeline to rotate along the grinding surface and perform operations, thereby realizing the detection of the accuracy of the grinding surface construction. After the pipeline is installed, the connection position between the device body 1 and the pipeline is adjusted, and the connecting rod 2 rotates relative to the device body 1, driving the monitoring component 4 to move along the connection position. The monitoring component 4 is used to monitor the sealing of the pipeline connection position.

[0077] As a specific implementation of the embodiment of the present invention, please refer to Figures 9 to 11 The device body 1 can generate reciprocating motion along the axial direction of the pipeline. The position of the device body 1 relative to the pipeline can be adjusted according to the construction process.

[0078] In any feasible embodiment, the device body 1 can be used to be connected and fixed to the outer side of the pipeline, and can move relative to the pipeline along the axial direction when necessary.

[0079] In any feasible embodiment, the device body 1 is used to be connected and fixed to the inner wall surface of the pipeline, and can move axially relative to the pipeline when necessary.

[0080] In some feasible embodiments, the device body 1 is provided with a plurality of connection components 11. The device body 1 is connected and fixed with the pipeline or moves relative to the pipeline by cooperating with the plurality of connection components 11. Specifically, the device body 1 includes a housing and an energy supply component disposed in the housing.

[0081] A first running wheel rotatably connected to the housing, a driving motor disposed in the housing and meshing with the first running wheel, the driving motor being electrically connected to the energy supply component. The driving motor is also connected to a control component. The control component includes a wireless communication structure.

[0082] In this embodiment, the connection assembly 11 includes an elastic plate 111 and a walking structure 112 connected to the elastic plate 111. One end of the elastic plate 111 is connected to the housing of the device body 1, and the other end is connected to the walking structure 112. The walking structure 112 is electrically connected to the energy supply assembly.

[0083] In any feasible embodiment, the device body 1 is connected and fixed to the inner wall surface of the pipeline through the connecting assembly 11. There are at least two groups of connecting assemblies 11. Exemplarily, there are two groups of connecting assemblies 11, one of which is connected and fixed to the upper end surface of the device body 1, and the other end of the connecting assembly 11 is connected and fixed to the lower end surface of the device body 1. The two groups of connecting assemblies 11 are arranged opposite to each other (that is, the two groups of connecting assemblies 11 are arranged in a straight line). When the device body 1 is connected to the inner wall surface of the pipeline, the walking structure 112 of any connecting assembly contacts the upper end of the inner wall surface of the pipeline, and the walking structure 112 of the other connecting assembly contacts the lower end of the inner wall surface of the pipeline.

[0084] In any achievable embodiment, the device body 1 is connected and fixed to the outer side of the pipeline through the connecting component 11. Exemplarily, the connecting component 11 is provided with two groups, and the elastic plate 111 is an arc-shaped plate body, wherein one group of connecting components 11 is connected and fixed to the left end face of the device body 1, and the other end connecting component 11 is connected and fixed to the right end face of the device body 1. The two groups of connecting components 11 are arranged oppositely (i.e., the two groups of connecting components 11 are arranged in a straight line). When the device body 1 is connected to the outer wall of the pipeline, the device body 1 is located above the pipeline and contacts the pipeline, the walking structure 112 of any connecting component 11 is located on the left side of the device body 1 and contacts the outer side face of the pipeline, and the walking structure 112 of the other connecting component 11 is located on the right side of the device body 1 and contacts the outer side face of the pipeline. The elastic plate 111 of each group of connecting components 11 is elastically deformed and then restored to the initial state, thereby generating a force to achieve a stable connection between the device body 1 and the outer side face of the pipeline. The walking structure 112 is rotationally connected to the connecting component 11 through a rotating structure. The rotating structure can drive the walking structure 112 to rotate relative to the connecting assembly 11 when powered, so that the device can move along the pipeline in all use states. The walking structure 112 includes a driving motor connected to the rotating shaft structure, and a walking wheel connected to the driving motor (the structure is Fig.10 The driving motor can drive the walking wheel to rotate, thereby driving the device to move.

[0085] In any achievable embodiment, the device body 1 can be connected and fixed to the outer side surface of the pipeline through the connecting component 11. The device body 1 can also be connected and fixed to the inner wall surface of the pipeline through the connecting component 11. Specifically, the connecting component 11 is provided with six groups. The device body 1 includes four surfaces, front, back, left and right. The connecting components 11 are respectively arranged on these four surfaces. Among them, the elastic plates 111 of the four groups of connecting components 11 are arc-shaped plates. The four groups of connecting components 11 are divided into two groups, one of which is arranged on the left surface and the other end is arranged on the right surface. The elastic plates 111 of the two groups of connecting components 11 are straight plates. And any elastic plate 111 is connected to the front in rotation. The other elastic plate 111 is connected to the back in rotation, specifically, the rotation connection is realized by the rotating shaft structure, and the rotating shaft structure is electrically connected to the energy supply component. At this time, the six groups of connecting components 11 have two use states, one of which is that the device body 1 is located in the pipeline, and the four groups of elastic plates 111 are arc-shaped plate connecting components that are connected to the inner wall surface of the pipeline respectively. The two sets of elastic plates 111 are straight connecting assemblies connected to the inner wall of the pipe respectively. Another use state is that the device body is located outside the pipe, and at this time, two sets of connecting assemblies 11 of the four sets of elastic plates 111 are arc-shaped connecting assemblies connected to the outer side of the pipe. The two sets of elastic plates 111 are straight plates that rotate respectively, and rotate 90° from a parallel state relative to the surface to a vertical state, and contact the outer side of the pipe in a front-to-back arrangement relative to the device body 1.

[0086] As a specific implementation of the embodiment of the present invention, please refer to the fact that the length of the connecting rod 2 is adjustable. The length of the connecting rod 2 can be adjusted according to actual needs, which can effectively improve the convenience of using the device.

[0087] In some feasible embodiments, the connecting rod 2 includes a first rod body 21 connected to the device body 1 and a second rod body 22 rotatably connected to one end of the first rod body 21 away from the device body 1. The first rod body 21 is a telescopic rod. The monitoring component 4 is connected to one end of the second rod body 22 away from the first rod body 21.

[0088] In this embodiment, the grinding assembly 3 includes a connecting portion 31 movably connected to one end of the second rod body 22 away from the first rod body 21 and a grinding portion 32 connected to the connecting portion 31. Specifically, the connecting portion 31 is rotatably connected to the second rod body 22 through a rotating shaft structure. More specifically, the connecting portion 31 has two use states. In the first use state, the setting direction of the connecting portion 31 coincides with the axial direction of the second rod body 22, and the grinding portion 32 can monitor and fine-tune the roundness of the tube body. In the second use state, the connecting portion 31 is set at an angle to the axial direction of the second rod body 22. In this state, the monitoring assembly 4 is released, and the monitoring assembly 4 can collect the connection state of the connection position. The staff can judge the sealing of the connection position through the image collected by the monitoring assembly 4. In this state, the second rod body 22 can be equivalent to a "pull rod", and the device can be easily moved by dragging the second rod body 22.

[0089] In this embodiment, one end of the connecting portion 32 connected to the second rod body 22 is provided with a receiving groove 33 adapted to the monitoring component 4. The receiving groove 33 can protect the monitoring component 4 by accommodating the monitoring component 4 to prevent the external environment from causing damage to the monitoring component 4.

[0090] In this embodiment, the monitoring component 4 is electrically connected to the energy supply component. The polishing part 32 is electrically connected to the energy supply component.

[0091] Compared with the prior art, the present invention provides a method and device for constructing an assembled inspection well pipeline.

[0092] The elastic sealing ring is squeezed against the pipeline, and after deformation, the elastic sealing ring is tightly attached to the pipeline and the reserved hole, thereby increasing the sealing performance of the connection between the reserved hole and the inspection well chamber.

[0093] The use of the sealing ring can block water, and water cannot penetrate into the elastic sealing ring, thereby avoiding erosion and leakage after long-term contact with water.

[0094] As the extrusion force increases, the sealing ring contacts the drain pipe and the water outlet more closely, thereby improving the sealing effect.

[0095] The socket-and-spigot connection between the inspection well and the pipeline makes it easier to connect the pipeline and the inspection well, reduces construction procedures, reduces labor costs, improves work efficiency, and is not affected by seasonal temperature, etc.

[0096] The structure connected by this method of connecting prefabricated inspection well pipes has the characteristics of being able to deform at a certain angle without leaking; it is quick and simple to install, so that the prefabricated process can be uniformly applied, and the flexible connection between the pipe and the inspection well structure is maintained, which not only ensures the use function, but also guarantees the design function and facilitates construction.

[0097] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
