Description

Technical Field

[0001] The invention relates to the technical field of pipeline renewal in trenchless pipeline repair, and in particular to a sludge treatment system for pipeline milling and diameter expansion. Background Art

[0002] Trenchless repair technology (trenchless) refers to the use of various rock and soil drilling equipment and technical means, through guidance, directional drilling and other means, in the case of excavation of a very small part of the surface (generally refers to the small area of ​​​​entrance and exit excavation), to lay, replace and repair various underground pipelines. New construction technology will not hinder traffic, will not damage green space and vegetation, will not affect the normal life and work order of shops, hospitals, schools and residents, and solve the interference of traditional excavation construction on residents' lives, and the damage and adverse effects on traffic, environment, and surrounding building foundations, so it has a high social and economic effect. In the trenchless repair technology, there is a technical direction for the repair of small and medium-sized concrete pipe tissues, which usually requires milling the inside of the damaged cement pipe to adapt to the updated metal pipe.

[0003] In the prior art, for small concrete pipe milling, expansion and renewal tunnel boring machines, the commonly used slag removal methods include mud and water circulation slag removal, which requires the front of the machine head to be blocked to form a closed space, which is relatively complicated, and the mud pipe is usually small. The concrete pipe to be milled usually has a steel keel / steel strand inside, and the steel bars after milling and crushing are not easy to discharge; in addition, the equipment space required for the treatment of waste mud is relatively large. In addition, there is rear spiral shaft slag removal, which also requires the front of the machine head to be blocked to form a closed space, and the spiral passes through the inside of the tunnel boring machine, occupying a large space of the host equipment, resulting in a narrow layout inside the tunnel boring machine.

[0004] Therefore, a slag treatment system at the front end is urgently needed. Summary of the invention

[0005] In order to overcome the technical solution in the prior art that mud / slag discharge requires occupying the space of the tunnel boring machine, a front-type mud and slag treatment method is adopted in the mud and slag treatment used for milling and expanding small and medium-diameter pipes. By respectively arranging tunneling equipment and slag discharge systems on both sides of the inspection well / working well, the purpose of not arranging a slag discharge device inside the tunneling device is achieved.

[0006] The technical solution adopted by the present invention is: a sludge treatment system for pipe milling and diameter expansion, comprising:

[0007] pipeline;

[0008] A milling device, for milling the inner wall of the pipeline or expanding the inner diameter of the pipeline;

[0009] An external discharge device is located at the front end of the milling device in the forward direction, moves with the milling device, and discharges the sludge produced by the milling device outwardly along the forward direction of the milling device;

[0010] A collecting bin is used to collect the sludge at the discharge end of the external discharge device.

[0011] Furthermore,

[0012] The collecting bin is connected to the milling device and moves synchronously with the external discharge device.

[0013] Furthermore, it also includes:

[0014] The mud and water circulation device utilizes the mud and water system to extract the mud residue inside the collection bin and inject mud into the collection bin.

[0015] Furthermore, it also includes:

[0016] Car;

[0017] The collecting bin is arranged on the trolley, and the trolley moves synchronously with the external discharge device.

[0018] Furthermore,

[0019] The external discharge device utilizes the reciprocating motion of the trolley to discharge the sludge.

[0020] Furthermore, it also includes:

[0021] A mud-water circulation device, utilizing a mud-water system to extract mud residue from the collecting bin and inject mud into the collecting bin;

[0022] The mud and water circulation device is connected to the trolley.

[0023] Furthermore, it also includes:

[0024] A vacuum collecting device is provided with a collecting pipeline which can move synchronously with the trolley to collect the mud stored in the collecting bin.

[0025] The beneficial effects of the present invention compared to the prior art are: the external discharge device and the collection bin are both arranged at the front end of the milling direction, and a variety of slag discharge modes are used to achieve the purpose of front-end slag discharge, thereby realizing a technical solution without setting a slag discharge path or device inside the milling device.

[0033] The technical solutions in the embodiments are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In the description of the present invention, it should be understood that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. are based on the orientations 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 operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0034] In order to overcome the technical solution in the prior art that mud / slag discharge requires occupying the space of the tunnel boring machine, a front-type mud and slag treatment method is adopted in the mud and slag treatment used for milling and expanding small and medium-diameter pipes. By respectively arranging tunneling equipment and slag discharge systems on both sides of the inspection well / working well, the purpose of not arranging a slag discharge device inside the tunneling device is achieved.

[0035] See also Figures 1 to 5 , the technical solution adopted by the present invention is as follows:

[0036] A sludge treatment system for pipe milling and diameter expansion, comprising:

[0037] Pipeline 100; in this embodiment, the pipeline 100 refers to a cement pipe, or other plastic pipes or conveying cavities that need to be repaired.

[0038] The milling device 200 mills the inner wall of the pipe 100, or expands the inner diameter of the pipe 100; the milling device 200 is usually a tunnel boring mechanism with a tool set at the front end, but because the diameter of the pipe to be repaired is usually not the same as the cross-sectional size of the tunnel, a tunnel boring mechanism with a smaller specification that matches the pipe to be repaired will be used. In this case, it is very difficult to set a mud and slag discharge device inside the tunnel boring mechanism, and a certain closed space needs to be generated at the end to meet the purpose of mud and water balance and slag absorption. The inventive point of this embodiment is that in the traditional non-excavation pipeline repair system, the slag absorption conditions of the normal tunneling device are not available, and referring to the characteristics of pipeline repair, an inspection well or a construction well is generally set in one section, so it has the particularity of openings at both ends. On this basis, a front-type slag discharge system is designed.

[0039] See also Figure 1 The external discharge device 300 is located at the front end of the milling device 200 in the forward direction, and moves with the milling device 200 to discharge the mud residue produced by the milling device 200 outward along the forward direction of the milling device 200;

[0040] The collecting bin 400 collects the sludge discharged from the external discharge device 300 .

[0041] In some embodiments,

[0042] The collecting bin 400 is connected to the milling device 200 and moves synchronously with the external discharge device 300. There are many ways to achieve synchronous movement, please refer to Figure 1 and Figure 2 The collecting bin 400 can be mounted on the outside. By using the principle of bearings, if the milling device 200 needs to rotate, the collecting bin 400 uses bearings to remain relatively still under the action of gravity. If the milling device 200 does not need to rotate, the collecting bin 400 is fixedly connected.

[0043] In some embodiments, see Figure 2 , the external discharge system utilizes muddy water circulation and also includes:

[0044] The mud and water circulation device 500 uses a mud and water system to extract the mud residue inside the collecting bin 400 and inject mud into the collecting bin 400. The mud and water circulation device 500 is located at the front end of the excavation direction, that is, the forward direction of the milling device 200.

[0045] In some other embodiments, please refer to Figure 3 , using the trolley 600, to overcome the difficulty of setting up the circulation path, also includes:

[0046] Car 600;

[0047] The collecting bin 400 is arranged on the trolley 600, and the trolley 600 moves synchronously with the external discharge device 300. Since the path to be repaired is usually a pipeline, the conventional trolley 600 only needs to keep reciprocating in the path, which greatly reduces the difficulty.

[0048] In some other embodiments, see Figure 3 , the sludge is discharged by utilizing the follow-up movement of the trolley 600.

[0049] The external discharge device 300 utilizes the reciprocating motion of the trolley 600 to discharge the sludge.

[0050] In some other embodiments, see Figure 4 , a receiving port of the external discharge device 300 is arranged on the trolley 600 to achieve the purpose of synchronous movement of the receiving port and the milling device 200, and also includes:

[0051] The mud and water circulation device 500 utilizes the mud and water system to extract the mud residue inside the collecting bin 400 and inject mud into the collecting bin 400;

[0052] The mud and water circulation device 500 is connected to the trolley 600 .

[0053] In some embodiments, the external discharge device 300 has many other modes, including:

[0054] The vacuum collecting device 700 is provided with a collecting pipeline that can move synchronously with the trolley 600 to collect the sludge stored in the collecting bin 400 .

[0055] During the specific implementation, the milling device 200 enters the pipeline 100, and uses the tool set at the forward end of the milling device 200 to mill the inner wall of the pipeline 100 to achieve the purpose of expanding the diameter. At the same time, the external discharge device 300 collects the mud milled and transports it to the collection bin 400. In some embodiments, the collection bin 400 is connected to the external discharge device 300. In some embodiments, the collection bin 400 is fixedly connected to the trolley 600, and the external discharge is achieved with the help of the power of the trolley. It should be noted that since the specifications of the pipeline to be repaired are usually small, the selection of the trolley 600 can be flexibly selected according to the size of the pipeline repair, or a receiving port of the mud circulation or vacuum slag extraction system is set on the trolley 600, and only the follow-up of the trolley 600 is used to set the power externally to achieve the external discharge of mud slag.

[0056] The beneficial effect is: the external discharge device and the collection bin are both arranged at the front end of the milling direction, and a variety of slag discharge modes are used to achieve the purpose of front-end slag discharge, thereby realizing a technical solution without setting a slag discharge path or device inside the milling device.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
