A high-strength force transmission column and its manufacturing method

Abstract

The invention belongs to the technical field of rock mass test and detection equipment, and in particular relates to a high-strength force transmission column, which includes a pin sleeve; a composite material cavity, which is set in the middle of the outer circumference of the pin sleeve; and a sheath, which is set in the middle of the outer circumference of the pin sleeve. The upper and lower parts of the outer circumference of the pin sleeve have an outer diameter equal to the outer diameter of the composite cavity. The present invention also provides a method for manufacturing a high-strength force transmission column, including pretreatment of carbon fiber mesh and steel wire mesh impregnated with resin; placing the plug sleeve at the center of the cylindrical mold; carbon fiber mesh sheet and resin-impregnated steel mesh sheet; when the stacking quantity is reached, pressurize axially to make the billet tightly bonded; exhaust and dry the cylindrical mold; The upper and lower sheaths are bonded externally at both ends. The high-strength force transmission column of the invention is light in weight, easy to transport, easy to install and disassemble, has anti-corrosion performance and long service life.

Description

technical field [0001] The invention belongs to the technical field of rock mass test and detection equipment, and in particular relates to a high-strength force transmission column and a manufacturing method thereof. Background technique [0002] The force transmission column is a component used to transmit force. In geotechnical tests, it is used with a jack to transmit output force. The force transmission column is made of thick-walled steel pipe, and has various length specifications. In the test, it can be matched according to actual needs to form different lengths. The joints between each section of the force transmission column are adopted. [0003] There are the following problems in the currently used steel force transmission columns: [0004] 1. The weight is heavy and heavy, the transportation cost is high, and the transportation cost at the test site is large; [0005] 2. Installation and disassembly are time-consuming and labor-intensive, and there are potenti...

AI Technical Summary

Problems solved by technology

[0004] 1. Heavy weight, high transportation costs, and high transportation expenses at the test site;

[0005] 2. Installation and disassembly are time-consuming and labor-intensive, and there are potential safety hazards;

[0006] 3. If the socket length is too short, the socket ring is easily deformed by force, and there are potential safety hazards;

[0007] 4. The steel force transmission column is used in the humid environment of the cavern, which is severely corroded and has a short service life
