High-strength underground pipe connector for improving soil in saline and alkaline land

Abstract

The invention provides a high-strength underground pipe connector for improving soil in saline and alkaline land. The high-strength underground pipe connector comprises a connector body, wherein the connector body is tubular and comprises a rotary clamping part and connecting parts; the connecting parts are positioned on two sides of the rotary clamping part; external threads matched with an underground pipe are arranged on the connecting parts; an anti-skid clamping groove which is inwards sunken is formed in the outer surface of the rotary clamping part; a protecting jacket sleeves the outside of each connecting part; the inner diameter of each protecting jacket is greater than the outer diameter of the corresponding connecting part; a position, close to the rotary clamping part, of each protecting jacket, is connected with the rotary clamping part. The high-strength underground pipe connector disclosed by the invention is high in corrosion resistance; threaded connecting parts are utilized to be matched with the threads of the underground pipe, so that the thread connecting strength is high; for further improving the connecting strength, the protecting jackets sleeve the outsides of the connecting parts, and the protecting jackets and the connecting parts mutually act to clamp the underground pipe between the protecting jackets and the connecting parts; meanwhile, the high-strength underground pipe connector has the advantage of preventing the leakage of the connector.

Description

technical field [0001] The invention relates to the technical field of engineering drainage, in particular to an underground pipe technology, in particular to a high-strength underground pipe connection joint used in soil improvement of saline-alkali land. Background technique [0002] As we all know, one of the most common technologies used in the improvement of saline-alkali land is the salt discharge technology of the hidden pipe, which is simple in structure and easy to use. The length of a long hidden pipe is generally 100 meters in length, which is more convenient during the laying process. The second is to use a shorter hidden pipe, generally about 10 meters in length. The shorter the length of the hidden pipe, the easier it is to lay. In the process, the number of joints of the underground pipe is more, due to the difference in the geographical area of ​​construction, such as the cold area in the north, due to the defect that the material of the underground pipe is h...

[0002] As we all know, one of the most common technologies used in the improvement of saline-alkali land is the salt discharge technology of the hidden pipe, which is simple in structure and easy to use. The length of a long hidden pipe is generally 100 meters in length, which is more convenient during the laying process. The second is to use a shorter hidden pipe, generally about 10 meters in length. The shorter the length of the hidden pipe, the easier it is to lay. In the process, the number of joints of the underground pipe is more, due to the difference in the geographical area of ​​construction, such as the cold area in the north, due to the defect that the material of the underground pipe is hardened by the cold in winter and is easy to break, it is not possible to use the dark pipe in rolls during the laying process. pipe, only a single 10-meter hidden pipe can be used

[0003] The general method of connection between two adjacent hidden pipes is a tie. After adjustment, the iron wire is used to bind the periphery. The main purpose is to prevent the joints from being pulled apart by force during the laying of the hidden pipes, and to improve the connection of the joints. Strength, and then prevent leaks at the joints of buried low-rise pipes, causing salt leakage and affecting the effect of land improvement. After long-term use, the iron wire will break after being corroded, and it will not be fixed.
