specific Embodiment approach 1

[0014] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment, a kind of foam lightweight ball test piece forming device described in this embodiment comprises top cover 1, upper hemisphere mold 2, lower hemisphere mold 3 and positioning pin 4, and upper hemisphere mold 2 and lower hemisphere mold 3 are formed by upper Connected sequentially from top to bottom, the upper surface of the upper hemispherical mold 2 is provided with a grouting port 2-1, the top cover 1 is installed on the grouting port 2-1, and the lower end of the positioning pin 4 passes through the top cover 1 and is inserted into the upper hemispherical mold 2 In the positioning pin hole 2-2 on the upper surface. The forming device described in this embodiment is used to process a spherical test piece with a diameter of 100mm, and the slurry is poured from the grouting port at the top of the upper hemisphere.

specific Embodiment approach 2

[0015] Specific implementation mode two: combination Figure 1 to Figure 3 To describe this embodiment, the upper surface of the top cover 1 of a foam lightweight ball test piece forming device described in this embodiment is provided with an excess slurry overflow port 1-1. In this embodiment, the slurry is poured to the grouting port, the top cover is pressed in and fixed, the excess slurry will flow out from the overflow port, and the spherical test piece is formed and completely closed, thereby avoiding the problem of defects on the top of the spherical surface. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation mode three: combination Figure 1 to Figure 3 To illustrate this embodiment, the upper surface of the top cover 1 of the foam lightweight ball test piece forming device described in this embodiment is provided with a plurality of top cover fixing threaded holes 1-2 evenly distributed along the circumferential direction. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to forming devices and testing methods, in particular to a light foam ball test piece forming device and a testing method, and belongs to the field of road and bridge construction. The problems that the appearance of a light foam ball test piece formed by an existing light foam ball production forming process is defective, and the homogeneity is not good are solved. The light foam ball test piece comprises a top cover, an upper half ball mold, a lower half ball mold and a positioning pin. The upper half ball mold and the lower half ball mold are sequentially connected from top to bottom; a grouting opening is formed in the upper surface of the upper half ball mold; the top cover covers the grouting opening; and the lower end of the positioning pin penetrates through the top cover to be inserted into a positioning pin hole in the upper surface of the upper half ball mold.

Description

technical field [0001] The invention relates to a forming device and a test method, in particular to a foam lightweight ball test piece forming device and a test method, belonging to the field of road and bridge construction. Background technique [0002] Lightweight spherical material is a new type of roadbed filling material obtained by pouring foam light soil slurry into a specific spherical material forming mold, and releasing the mold after the slurry solidifies and hardens. According to the definition of foamed lightweight soil in the "Technical Regulations for Cast-in-place Foamed Lightweight Soil", foamed lightweight soil refers to the application of physical methods to prepare foaming agent aqueous solution into foam, and the necessary components of cement-based cementitious materials, water It is a lightweight material formed by mixing and stirring optional components aggregates, admixtures, and admixtures in a certain proportion, and hardening through physical and...
