Embodiment Construction

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0055]The present invention provides a device for testing the mechanical properties of the anchoring slurry-matrix interface in soil ruins, including a loading mechanism 110 and a sample preparation mechanism 120, wherein the loading mechanism is a press, which includes a workbench 111 at the bottom. A column 112 is arranged at the upper corner of the table 111, and an upper beam 113 is arranged at the top of the column. A movable beam 114 is arranged below the upper beam 113 , and the movable beam 114 can move up and down so as to carry out pressure loading. The lower part of the movable beam 114 is fixed with an upper jaw 115 , and is connected with the loading rod 130 by a pin 116 through the upper jaw 115 . A lower jaw 117 is arranged above the workbench 111 .

Abstract

The invention provides a device for testing interfacial mechanical characteristics of an earthen site anchoring slurry-substrate. The device comprises a loading mechanism and a sample preparation mechanism, wherein the sample preparation mechanism comprises a sample preparation base, a plurality of side wall blades, blade lock rings, a polished round core and a threaded core; a through hole is arranged in the center of the sample preparation base; the plurality of side wall blades are arranged at the upper part of the sample preparation base, are in an arc form and are enclosed into a hollow cylinder; the blade lock rings sleeve the outer sides of the blade lock rings respectively to hold the side wall blades; and the polished round core and a threaded core can be inserted into the through hole in the sample preparation base and the samples with different hole wall roughness can be manufactured separately. The invention further provides a method for testing the interfacial mechanical characteristics of the earthen site anchoring slurry-substrate.

Description

technical field [0001] The invention belongs to the technical field of research on the mechanical properties of the slurry-matrix interface of an anchoring system in the protection of earthen ruins, and in particular relates to a device and method for testing the mechanical properties of the anchoring slurry-matrix interface of earthen ruins. Background technique [0002] As an important part of my country's excellent cultural heritage, earthen sites are spread all over the country, and they have great historical, artistic, scientific, social and cultural values. However, due to the serious impact of natural environmental factors and human activities for a long time, most of the earthen sites are in an endangered state. In order to delay the deterioration of the earthen ruins and improve the life of the earthen ruins. Based on the concept and criteria of cultural relics protection, anchoring has become a generally accepted mechanical stability technology with good concealme...
