Problems solved by technology

However, the specimen prepared by this method still needs to be processed twice, such as cutting and leveling. The operation is complicated and requires a high level of operation of the operator. It is not a standard test piece, and the detection cost is very high in practical applications, almost 10 times more than the above two test pieces

Embodiment Construction

[0032] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Figures 1 to 5 It is a structural representation of the present invention.

[0034] The reference signs therein are: bottom mold 1, specimen mold cavity 1a, partition 11, lower fastening plate 13, upper mold 2, long side wall 21, wide side wall 22, upper fastening plate 23 , sealing ring 3, fastener 4.

[0035] As shown in the figure, the present invention discloses a device for making cement slurry test pieces. Three test pieces can be produced at one time by using the device, and the produced test pieces have good integrity and very small dimensional errors, and there is no need to for secondary processing. This device comprises bottom mold 1, and bottom mold 1 is a rectangular box with certain height, length and width, and it has an upper opening. In order to form multiple standard cement slurry specimens at one time without cutt...

Abstract

The invention discloses a device for manufacturing a cement paste test-piece and an application method thereof. The device comprises a bottom mold and an upper mold; two baffle plates are integrally molded in the cavity of the bottom mold; the cavity of the bottom mold is divided into three mutually independent test-piece molds by the two baffle plates to form a triple test mold with a bottom; each test-piece mold cavity is cube mold cavities with the same size, and an air inlet is formed in the bottom surface of each test-piece mold cavity; the upper mold is detachably hermetically connectedwith the upper opening of the bottom mold. The application method of the device comprises assembling a device, painting machine oil, collecting cement paste, injecting the cement paste into the bottommold, molding a test-piece body, standing the test-piece body, demolding the test-piece body and maintaining the test-piece body to a test age. By using the cement paste test-piece provided by the invention, the cement paste can be molded by one-time casting, with no need to secondarily replenish slurry, after the test-piece is cured, the secondary treatment is not needed either; the applicationmethod is simple and convenient, convenient to operate, and low in manufacturing cost of the test-piece.

Description

technical field [0001] The invention relates to a technology for making a cement slurry test piece, in particular to a device for making a cement slurry test piece and a method for using the same. Background technique [0002] Grouting technology is a simple, economical and effective geotechnical engineering reinforcement and water blocking method, which has been widely used in construction projects in various fields such as construction, water conservancy and hydropower, transportation, and mining. The most important role of cement grouting technology in foundation engineering is reinforcement, and it is widely used in various construction methods, such as static drilling and rooting construction methods, SMW construction methods, cement mixing pile construction methods, etc. In the construction process of the foundation project, the prepared cement slurry is injected into the pores of the soil, combined with the soil, and undergoes a physical and chemical reaction, thereby...
