Description

Technical Field

[0001] The utility model belongs to the technical field of cement pipes, in particular to a water conservancy pipeline reinforcement device. Background Art

[0002] The water conservancy pipeline reinforcement device is a device used to strengthen and protect various pipelines used in water conservancy projects. These devices can use a variety of technical means to achieve the reinforcement of pipelines in different application scenarios. The reinforcement of cement pipelines can be carried out by grouting around the pipeline. Specifically, grouting is performed on the outside of the cement pipeline to form a protective layer to prevent damage to the cement pipeline caused by disrepair. Grouting technology is an economical and efficient anti-seepage treatment method. Ordinary Portland cement is relatively low in price and easy to obtain, and can significantly reduce the cost of water leakage treatment. It is especially suitable for projects suitable for the use of cement pipelines.

[0003] When cement pipes are used as water conservancy pipes, it is particularly time-consuming and labor-intensive to reinforce them by applying cement; when grouting is used for reinforcement, a lot of grouting is injected at the joints, causing unnecessary waste of concrete materials flowing to other places on the outer wall of the pipe. Utility Model Content

[0004] The purpose of the utility model is to provide a water conservancy pipeline reinforcement device to facilitate the sealing of cement pipeline joints and pipeline maintenance.

[0005] The water conservancy pipeline reinforcement device comprises a first cement pipe arranged to be connected to the left and right, the left end of the first cement pipe is transversely connected to the second cement pipe, the right ends of the first cement pipe and the second cement pipe are both fixed with a first boss along the circumference near the end, the left ends of the first cement pipe and the second cement pipe are both fixed with a second boss along the circumference near the end, at least four through holes distributed in a rectangular shape are opened on the first boss and the second boss at the connection of the first cement pipe and the second cement pipe along the circumference, the through holes are connected to the left and right and are arranged symmetrically, bolts are independently installed in the through holes, and the screw rods of the bolts transversely pass through the through holes on the first boss and the second boss in sequence;

[0006] A bottom plate is longitudinally placed on the bolt below the connection between the first cement pipe and the second cement pipe, and the front and rear ends of the bottom plate are both located outside the first boss and the second boss; vertical plates are vertically placed in the bolts in front and behind the connection between the first cement pipe and the second cement pipe, and the lower ends of the vertical plates are in contact with the upper surface of the bottom plate, and the upper ends are located above the first boss and the second boss, and the bottom plate and the two vertical plates form a groove structure with an opening facing upward on the inner side of the bolt.

[0007] The first cement pipe and the second cement pipe are just examples of two cement pipe connection methods, which extend to the left and right when actually used. First, place the first cement pipe and the second cement pipe in the installation groove. After aligning the left and right, the through holes on the first boss and the second boss at the connection of the first cement pipe and the second cement pipe are symmetrically distributed on the left and right. Then, bolts are inserted into the through holes. The bottom plate is placed on the bolts below the connection of the first cement pipe and the second cement pipe. The vertical plates are vertically placed in the bolts in front and behind the connection of the first cement pipe and the second cement pipe. The bottom plate and the two vertical plates form a groove structure with an opening facing upward on the inner side of the bolt. Grout is injected into the groove to fix the connection of the first cement pipe and the second cement pipe. It is very convenient to seal the pipe. After grouting, the bolts, vertical plates and bottom plates can be removed and reused. If one section of the cement pipe is damaged in the later stage, taking the damaged repair of the first cement pipe as an example, a rod-like structure such as a steel bar can be inserted into the through hole between the first boss and the second boss on the first cement pipe. A plate wider than the bottom plate is placed on the steel bars under the first cement pipe, and plates wider than the vertical plates are placed vertically on the front and back of the first cement pipe to form a groove structure with an opening facing upward. Grouting is injected into the groove to complete the damaged maintenance and reinforcement of the first cement pipe. Maintenance and reinforcement can be carried out without removing the pipe, which is very convenient. In actual use, the bolts can also be replaced with other rod-like structures.

[0008] Furthermore, the left end of the first cement pipe and the right end of the second cement pipe are connected in a tongue-and-groove manner.

[0009] The first cement pipe and the second cement pipe that are tongue-and-groove matched can increase the stability at the connection.

[0010] Furthermore, a connecting pipe communicating left and right is provided between the first cement pipe and the second cement pipe, the left end of the connecting pipe is connected to the right end of the second cement pipe, and the right end is connected to the left end of the first cement pipe.

[0011] The connecting pipe can be connected between two sections of the pipe when the installed pipes need to be extended. At the same time, the connecting pipe is fixed between the first cement pipe and the second cement pipe by grouting, so that the connection between the first cement pipe and the second cement pipe is more stable and firm.

[0012] Furthermore, both left and right ends of the first cement pipe and the second cement pipe are provided with limiting grooves in an annular structure into which the ends of the connecting pipes can extend independently.

[0013] The limiting groove has an annular structure. After the end of the connecting pipe is independently extended into the limiting groove, the outer diameter of the connecting pipe is larger than the inner diameter of the first cement pipe and the second cement pipe, and smaller than the diameter of the limiting groove; the connecting pipe fits the inner wall of the first cement pipe and the second cement pipe, and the limiting groove is convenient for connection with the end of the connecting pipe, which is convenient for quick positioning and preliminary fixation, and the part of the connecting pipe extending into the first cement pipe and the second cement pipe can support the ends of the first cement pipe and the second cement pipe, so that the first cement pipe and the second cement pipe are more stable at the connection.

[0014] Furthermore, a rubber ring is arranged in the limiting groove.

[0015] The rubber ring can prevent leakage at the connection points between the first cement pipe, the second cement pipe and the connecting pipe respectively.

[0016] Furthermore, the outer peripheries of the first boss and the second boss are in a square structure.

[0017] The first and second bosses of the square structure facilitate left-right alignment of the first cement pipe, the second cement pipe and the through hole.

[0018] Furthermore, there are twelve through holes, which are evenly spaced and arranged in a square shape.

[0019] There are twelve through holes distributed in a square, and two through holes between two adjacent right angles. This can increase the load-bearing capacity of the vertical plate and the bottom plate during grouting. The evenly spaced through holes also allow the first cement pipe and the second cement pipe to be aligned left and right without having to worry about whether the through holes are aligned.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] First, place the first cement pipe and the second cement pipe in the installation groove. After aligning the left and right sides, the through holes on the first boss and the second boss at the connection of the first cement pipe and the second cement pipe are symmetrically distributed. Then, bolts are inserted into the through holes. The bottom plate is placed on the bolts below the connection of the first cement pipe and the second cement pipe. The vertical plates are vertically placed in the bolts in front and behind the connection of the first cement pipe and the second cement pipe. The bottom plate and the two vertical plates form a groove structure with an opening facing upward on the inner side of the bolt. Grout is injected into the groove to seal the connection of the first cement pipe and the second cement pipe. It is very convenient. After grouting, the bolts, vertical plates and bottom plates can be removed and reused. If one section of the cement pipe is damaged at a later time, taking the repair of the first cement pipe as an example, a rod-like structure such as a steel bar can be inserted into the through hole between the first boss and the second boss on the first cement pipe. A plate wider than the bottom plate is placed on the steel bars under the first cement pipe, and plates wider than the vertical plates are placed vertically on the front and back of the first cement pipe to form a groove structure with an opening facing upward. Grouting is injected into the groove to complete the damaged maintenance and reinforcement of the first cement pipe. Maintenance and reinforcement can be carried out without removing the pipe, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
