Abstract
Description
Technical Field
[0001] The present application relates to the technical field of road engineering, and in particular to a prefabricated inspection well pipeline interface closed mold. Background Art
[0002] A prefabricated inspection well refers to a concrete inspection well that is pre-produced in the factory and can be directly installed after being transported to the construction site. It is mainly used for the connection, adjustment and diversion of sewage, rainwater and other pipelines, and is convenient for construction personnel to inspect and repair pipelines. At the same time, it can also ensure the integrity and aesthetics of the road surface. Therefore, prefabricated inspection wells are widely used in municipal roads, water conservancy projects, construction and other fields.
[0003] The side of the prefabricated inspection well is usually equipped with a pipe interface for connecting the pipe, but the outer diameter of the pipe cannot be completely matched with the inner diameter of the pipe interface, and there is an assembly error. Therefore, after the pipe is inserted into the pipe interface, it is necessary to use concrete to seal the pipe interface to achieve a fixed and airtight connection between the pipe and the prefabricated inspection well. At present, in the construction of the sealing of the pipe interface of the prefabricated inspection well, the open filling method is often used to seal the interface: first, mortar is directly poured on the inside and outside of the pipe interface, and then triangular ash is poured on the outside of the pipe interface.
[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above-mentioned technology has at least the following technical problems: the mortar is in a free state, and there is no sealing facility to support it during construction. Therefore, there will be gaps or bubbles in the mortar during the construction process, resulting in the mortar being not dense enough, affecting the construction quality, and the mortar filling is completely manually operated, which is time-consuming, labor-intensive and costly.
[0005] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art. Summary of the invention
[0006] In view of at least one of the above technical problems, the present disclosure provides a prefabricated inspection well pipe interface closing mold, which seals the pipe and the well wall through a detachable fixing ring and a seal, and then uses concrete to close the pipe interface, thereby solving the problems of poor pipe interface sealing quality and high material and construction costs in the prior art. The mold is easy to disassemble and assemble, and has a good sealing effect, so that the concrete can be fully and evenly distributed around the pipe, thereby improving the pipe interface sealing quality.
[0007] According to one aspect of the present disclosure, a prefabricated inspection well pipe interface closed mold is provided, comprising a fixing ring for being sleeved outside the pipe and fixed relative to the inspection well wall, and a sealing member arranged between the corresponding end face of the fixing ring and the pipe; after the corresponding end faces of the fixing ring are respectively connected to the pipe and the well wall, a casting cavity for filling concrete slurry is formed between the three; the fixing ring comprises at least two fixing ring segments, and the fixing ring segments are correspondingly detachably connected; the fixing ring comprises a pouring port facing vertically upwards and used for pouring slurry into the pouring cavity.
[0008] In some embodiments of the present disclosure, the sealing member is a sealing plate whose length matches the circumference of the corresponding cross section of the pipeline.
[0009] In some embodiments of the present disclosure, the outer diameter of the seal is greater than the inner edge diameter of the fixing ring; and the sealing plate is a rubber plate.
[0010] In some embodiments of the present disclosure, the fixing ring includes a first fixing ring segment, a second fixing ring segment, and a third fixing ring segment.
[0011] In some embodiments of the present disclosure, the first fixing ring segment and the second fixing ring segment are correspondingly screwed, and the first fixing ring segment and the third fixing ring segment, and the second fixing ring segment and the third fixing ring segment are correspondingly screwed or hinged.
[0012] In some embodiments of the present disclosure, the injection port is provided at the top of the first fixing ring segment and the second fixing ring segment.
[0013] In some embodiments of the present disclosure, a sealing folded edge for pressing the sealing member is provided at the corresponding end surface of the fixing ring for contacting the sealing member.
[0014] In some embodiments of the present disclosure, the fixing ring is correspondingly threadedly connected to the wall of the inspection well.
[0015] One or more technical solutions provided in the embodiments of the present application have at least any of the following technical effects or advantages:
[0016] 1. At least one layer of sealing is provided between the fixing ring and the pipeline, which not only realizes the sealing between the fixing ring and the pipeline, but also can make up for the matching error between the fixing ring and the pipeline, thereby improving the applicability of the fixing ring.
[0017] 2. The fixing ring and the seal are both detachable. The fixing ring segments are correspondingly screwed or hinged. The seal is made of a rubber plate whose length matches the circumference of the corresponding cross section of the pipe. This makes the mold easy to disassemble and assemble, with high construction efficiency and reusable, reducing material costs.
[0018] 3. The pipe interface is sealed and connected with the pipe and the well wall by a fixing ring, and a fixing ring is provided at the pipe interface inside and outside the well wall respectively. After pouring the concrete slurry, the slurry can flow in the casting cavity between the pipe, the fixing ring and the well wall, and finally evenly distribute around the pipe, filling the entire casting cavity, greatly improving the sealing quality of the concrete; and because the fixing ring is tightly connected with the pipe and the well wall, the concrete slurry can be prevented from flowing out of the mold, thereby avoiding the waste of slurry and saving material costs.

DETAILED DESCRIPTION
[0025] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The terms "first", "second", etc. involved in the present application are used to distinguish the objects described and do not have any order or technical meaning. The terms "connection" and "connection" involved in the present application, unless otherwise specified, include direct and indirect connections (connections).
[0027] Unless otherwise specified, the components, structures, and mechanisms involved in the following embodiments are conventional commercially available products.
[0028] The embodiment of the present application solves the technical problems of poor sealing quality of pipe interfaces and high material costs in the prior art by providing a prefabricated inspection well pipe interface sealing mold. Fixed rings are respectively arranged on the inner and outer sides of the prefabricated inspection well wall to be sealed and connected to the pipes, which can improve the quality of concrete pouring, avoid waste of concrete slurry, and save material costs.
[0029] This example discloses a prefabricated inspection well pipe interface sealing mold, which is used to seal the pipe 1 and the well wall 2 to achieve concrete pouring and sealing at the pipe interface. Figures 1 to 5 , including a fixing ring 3 used to be sleeved outside the pipeline and fixed relatively to the wall of the inspection well, at least one layer of sealing member 4 arranged between the corresponding end face of the fixing ring 3 and the pipeline 1; a sealing gasket is arranged between the fixing ring 3 and the well wall 2; after the corresponding end faces of the fixing ring 3 are respectively connected to the pipeline 1 and the well wall 2, a casting cavity for filling concrete slurry is formed between the three, and the fixing ring 3 includes a vertical upward pouring port 5 for pouring slurry into the pouring cavity, thereby realizing the closure of the pipeline interface.
[0030] See also Figure 1 The fixing ring 3 includes at least two fixing ring segments, and the fixing ring segments are correspondingly connected in a detachable manner; in this embodiment, the fixing ring includes a first fixing ring segment 6, a second fixing ring segment 7 and a third fixing ring segment 8. The corresponding connection points of the first fixing ring segment 6, the second fixing ring segment 7 and the third fixing ring segment 8 are provided with a first folded edge 9 facing outwards, so as to realize the connection between the fixing ring segments. The third fixing ring segment 8 is arranged at the bottom of the first fixing ring segment 6 and the second fixing ring segment 7. The third fixing ring segment 8 is correspondingly connected in a detachable manner with the first fixing ring segment 6 and the second fixing ring segment 7 by bolts, and of course, it can also be connected in a corresponding rotation by hinges; the first fixing ring segment 6 is correspondingly connected in a detachable manner with the second fixing ring segment 7 by bolts; the fixing ring 3 is a split circular ring structure (see Figure 2 ), or it can be a split rectangular structure (see Figure 3 ), easy to disassemble and assemble, which can greatly shorten the formwork time and improve construction efficiency.
[0031] See also Figure 2 The pouring port 5 is correspondingly arranged at the top of the first fixed ring segment 6 and the second fixed ring segment 7, and the pouring port 5 is arranged above the pipeline 1, so that the concrete slurry can naturally flow to various parts of the casting cavity, reducing the difficulty of construction operation.
[0032] See also Figure 1The outer edge of the fixing ring 3 is provided with a second folded edge 10 facing away from the pipe 1 on the side close to the well wall 2, so that the fixing ring 3 can be fixedly connected to the well wall 2 by bolts, and the connection is tight to prevent the concrete slurry from leaking out. The corresponding end surface of the fixing ring 3 for contacting the seal 4 is provided with a sealing folded edge 11 for pressing the seal 4. The sealing folded edge 11 is connected to the seal 4 to seal the pipe 1. The sealing folded edge 11 faces away from the well wall 2 to avoid the sealing folded edge 11 and the seal 4 blocking the contact between the concrete and the pipe 1, ensuring that the contact area between the concrete and the pipe 1 reaches the maximum.
[0033] See also Figure 4 The seal 4 is a sealing plate whose length matches the circumference of the corresponding cross-section of the pipeline. The sealing plate is a rubber plate that can be bent. The thickness of the sealing plate is 3 to 10 mm. The number of layers of the seal 4 is selected according to the outer diameter of the pipeline 1 and the inner diameter of the fixing ring 3 at the construction site to ensure that the outer diameter of the outermost seal 4 is at least 10 mm larger than the inner diameter of the fixing ring 3, thereby achieving the sealing of the pipeline 1. Since there is an error in the diameter of the pipeline 1 when it is prepared, at least one layer of seal 4 is arranged between the fixing ring 3 and the pipeline 1 to make up for the error between the fixing ring 3 and the pipeline 1, which helps to improve the application range of the fixing ring 3 and enhance its applicability. Since the seal 4 is formed by bending the sealing plate, the seal 4 has a detachable function. After the pipeline interface is closed, the fixing ring 3 and the seal 4 can be disassembled in turn and can be reused to avoid wasting resources.
[0034] See also Figure 4 Since there is a gap between the pipe 1 and the well wall 2, the pipe interfaces on both sides of the well wall 2 need to be closed, so the fixing rings 3 are used in pairs, which are respectively arranged on the outside and inside of the well wall 2; since fixing rings 3 are arranged on both sides of the well wall 2 to seal the pipe 1, when pouring concrete slurry, it can be ensured that the slurry will not flow out from the gap between the pipe 1 and the well wall 2, thereby ensuring that the concrete slurry fills the cavity between the pipe 1 and the fixing ring 3 and the well wall 2, thereby improving the sealing quality of the pipe interface.
[0035] For rectangular prefabricated inspection wells, during the construction of the flat well wall pipe interface closure, the seal is first wound around the outside of the pipe, and then the third fixed ring segment, the first fixed ring segment, and the second fixed ring segment are installed in sequence, and the fixed ring is fixed to the well wall by bolts. The inner and outer fixed rings of the well wall are installed simultaneously, and after the fixed ring is sealed with the pipe and the well wall, concrete slurry is poured through the pouring port, and a vibrator is used to vibrate to ensure that the concrete is densely combined; after the concrete solidifies, the fixed ring and the seal are removed in sequence, and the pipe interface is closed.
[0036] For the circular prefabricated inspection well, the fixed ring in the pipeline interface closed mold of the present application can be equipped with two bendable arc-shaped steel plates 12 (see Figure 5), which is arranged between the fixing ring and the well wall to close the gap between the fixing ring and the circular well wall to achieve sealing of the pipeline interface.
[0037] During the construction of the closure of the pipe interface on the arc surface of the circular prefabricated inspection well, the seals and fixing rings are successively put on the outside of the pipe, and then the arc steel plate and the fixing ring are connected by bolts. After the arc steel plate and the fixing ring are tightly connected, the arc steel plate is fixed to the well wall. After the installation of the inner and outer molds of the well wall is completed, concrete slurry is poured. After the concrete solidifies, the arc steel plate, fixing ring and seals are successively removed to complete the closure of the pipe interface.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
[0039] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the inventive concept. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
