DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For reference Figure 1-14 The present invention is described:

[0036] Embodiment 1: A large diameter pipe alignment connection device includes a connection chamber, which is a rectangular body structure as a whole. The connection chamber is a shell structure with a hollow interior, and also includes a connection hole 11 that penetrates the connection chamber in the left and right directions. The connection chamber is composed of an upper connection chamber 41 and a lower connection chamber 42 arranged up and down. The upper connection chamber 41 is opened downward, and the lower connection chamber 42 is opened upward. The connection hole 11 is located on the upper connection chamber 41 and the lower connection chamber 42. The upper side surface of the upper connection chamber 41 is provided with an injection hole 5 that is connected to the interior of the connection chamber, and two injection holes 5 are provided.

[0037] Fixed chambers are respectively provided on the left and right sides of the connecting chamber. The fixed chamber is a rectangular body structure as a whole. The fixed chamber is a shell structure with a hollow interior, and also includes a connecting hole 11 that penetrates the fixed chamber in the left and right directions. The fixed chamber is composed of an upper fixed chamber 61 and a lower fixed chamber 62 arranged up and down. The upper fixed chamber 61 is opened downward, and the lower fixed chamber 62 is opened upward. The connecting hole 11 is located on the upper fixed chamber 61 and the lower fixed chamber 62. An injection hole 5 that communicates with the interior of the fixed chamber is provided on the upper side surface of the upper fixed chamber 61, and two injection holes 5 are provided.

[0038] The connecting chamber and the fixing chamber can be made of plastic or of aluminum profiles.

[0039] It also includes a series connection hole 7 that penetrates the upper connecting chamber 41 and the lower connecting chamber 42 and the upper fixed chamber 61 and the lower fixed chamber 62 in the upper and lower directions. A series connection ground grasping nail 71 is connected in the series connection hole 7. The series connection ground grasping nail 71 penetrates from the series connection hole 7 and is driven into the soil. One is to form a fixed series connection between the upper and lower structures of the connecting chamber and the fixed chamber, and the other is to fix the connecting chamber and the fixed chamber with the soil. The series connection ground grasping nail 71 is a columnar structure. The series connection ground grasping nail 71 is an internal middle hole setting. The upper end of the series connection ground grasping nail 71 is provided with a limiting ring, and the diameter of the limiting ring is greater than the diameter of the series connection hole 7.

[0040] The two pipes 1 that need to be aligned and connected pass through the left and right fixed chambers respectively and enter the connecting chamber, and the ends of the two pipes 1 are butted and connected.

[0041] When laying the pipeline, first arrange the lower connecting chamber 42 and the lower fixing chamber 62 at the bottom of the groove. One lower connecting chamber 42 and two lower fixing chambers 62 cooperate to form an alignment connection point. Multiple alignment connection points are set in the straight line direction of the pipeline laying. Adjacent alignment connection points are connected by connecting beams 9. In this way, the distance between two adjacent alignment connection points is positioned and fixed. After the alignment connection points are laid, the pipeline 1 is hoisted and placed into the alignment connection points. The two pipelines 1 are in an aligned connection state. Then the upper connecting chamber 41 and the upper fixing chamber 61 are installed, and then the serial gripping nails 71 are driven into the serial connection holes 7.

[0042] The two pipelines 1 are connected through a connecting chamber and a fixing chamber. In the laying direction of the multiple pipelines 1, a connecting beam 9 connecting the two adjacent alignment connection points is provided. The two ends of the connecting beam 9 are respectively fixedly connected to the lower connecting chamber 42 or the lower fixing chamber 62 of the two alignment connection points. The connecting beam 9 is made of steel or aluminum profiles. The connecting beam 9 is mainly used to locate the distance between the two alignment connection points to avoid the alignment connection points being displaced in the length direction by the pipelines when the pipelines are hoisted and placed.

[0043] This forms a preliminary aligned connection to the pipe.

[0044] The pipe 1 passes through the connection hole 11 on the fixing chamber, and the outer wall of the pipe 1 is spaced from the inner wall of the fixing chamber to form a gap, and the gap between the pipe 1 and the fixing chamber is filled with a fixing material 2. The fixing material 2 is liquid concrete, which is injected into the interior of the fixing chamber from the injection hole 5. When the concrete solidifies, a fixed connection to the pipe 1 is formed. Concrete can be injected in layers, and new concrete can be injected and discharged after the lower layer is solidified. Through holes can also be set on the side wall of the fixing chamber to dissipate the moisture in the concrete, and the concrete flows out of the through holes and enters between the fixing chamber and the soil, which can also play a reinforcement role.

[0045] The pipe 1 passes through the connecting hole 11 on the connecting chamber, and the outer wall of the pipe 1 and the inner wall of the connecting chamber are spaced apart to form a gap, and the gap between the pipe 1 and the connecting chamber is filled with a connecting material 3. The connecting filler is formed by solidifying a liquid thermoplastic elastomer, such as liquid rubber, which can be injected into the connecting chamber through the injection hole 5. The liquid rubber fills the connecting chamber. After the liquid rubber solidifies, an annular connecting body is formed around the joint of the two pipes 1, and the connecting body is flexible and can undergo elastic deformation, so that the influence of the movement of the pipes on the joint of the two pipes can be resisted, and the joint of the two pipes can be prevented from breaking, cracking and damage. (After the two pipes 1 are docked in the connecting chamber, the joint of the two pipes can be wrapped and wrapped with a film to prevent the injected connecting material 3 from entering the interior of the two pipes 1)

[0046] The core invention of the present application is the connecting material 3. The connecting material 3 forms an elastic body, which surrounds and surrounds the joint of the two pipes 1 to form an elastic ring tube structure, which plays the role of connecting the two pipes, is sealed with the two pipes, and can be elastically twisted and swung, so as to resist the influence of the movement of the pipes caused by external soil activities.

[0047] After the fixing seasoning 2 and the connecting seasoning 3 are injected and the fixing seasoning 2 and the connecting seasoning 3 are solidified, the pipeline can be buried with soil.

[0048] The inner wall of the upper connecting chamber 41 is provided with an electric heating plate 8, which is fixedly attached to the inner wall of the upper connecting chamber 41. The upper side surface of the upper connecting chamber 41 is provided with a power connection post 81 connected to the electric heating plate 8, and two power connection posts 81 are provided. The main consideration of adopting this technical solution is that the connection between the two pipelines 1 can be maintained and repaired in the later stage. The buried soil can be dug to expose the upper connecting chamber 41, and then the two power connection posts 81 are connected to electricity. The electric heating plate 8 is powered on to generate heat, and the connecting seasoning 3 is heated and melted, so that the upper connecting chamber 41 can be opened, so that maintenance can be carried out.

[0049] The left and right sides of the lower end of the lower connecting chamber 42 respectively form a reversible connection with the lower end of the lower fixed chamber 62 (the reversible connection can be realized by a hinge structure). With this technical solution, one lower connecting chamber 42 and two lower fixed chambers 62 are arranged as a conjoined body, which is convenient for simultaneous installation in the groove. During installation, one lower connecting chamber 42 and two lower fixed chambers 62 are in a state of being closely connected in the left and right directions. After the pipeline is installed, the upper connecting chamber 41 and the upper fixed chamber 61 are installed. The above-mentioned conjoined structure is for the convenience of installation, and the reversible structure is to enable movement and deformation between the fixed chamber and the connecting chamber, so as to resist the possible movement of the pipeline and to ensure the stability and reliability of the connection.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
