Apparatus and method for on-site measurement of concrete penetration

Abstract

The invention discloses a device for concrete penetration field measurement and a method for concrete penetration field measurement, wherein the field measurement device comprises an outer neck, an inner neck and a sealing ring; the outer neck is fitted and closely connected with the inner structure of the inner neck, so as to form a measurement device body; the outer neck and the inner neck are equally divided into two symmetrical parts and tightly connected through the bolt; the handle is located on the outer neck; priming wires are evenly distributed on the surfaces of the outer neck and the inner neck; the sealing ring is located at the inside diameter place of the inside neck, and tightly fit with a water filling opening. On the basis of guaranteeing good tightness effect, the sealing device provides enough combining force to connect and fix the water filling opening with the wall body. By using the technology, the concrete penetration field measurement can be completed.

Description

technical field [0001] The invention relates to an on-site measuring device for concrete penetration, in particular to a device for fixedly connecting a water injection nozzle and a concrete wall body to be tested during an on-site concrete anti-seepage test. Background technique [0002] In the traditional impermeability test, the impermeability tester is used to test the concrete block to be tested in the laboratory. This method of operation can only be tested on the test block in the laboratory, which cannot meet the needs of the concrete impermeability test in the field environment, and has certain limitations. [0003] In the on-site concrete impermeability test, the difficulty lies in the connection device between the water injection port and the wall to be tested. The water pressure at the water injection port is about 2MPa, and the sealing device needs to provide sufficient bonding force to connect the water injection port and the wall. Traditional vacuum sealing m...

Problems solved by technology

[0004] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a concrete penetration field measurement device, the device connects and fixes the water injection port and the wall through the friction force generated by the contact between the striker and the wall, and solves the problem of traditional fixation. Insufficient binding force in the method, realized the on-site measurement of concrete penetration
