Embodiment Construction

[0018] The dilatometer provided by the present invention will be further described in detail below in conjunction with specific embodiments.

[0019] Such as figure 1 As shown in , the dilatometer of the present invention at least includes a base 1 , a container 2 placed above the base 1 , a vertical dial gauge 5 and a horizontal dial gauge 6 . The container 2 is composed of a bottom plate and a side wall and is in the shape of a cuboid, and the cuboid soil sample is placed in the container 2 .

[0020] A vertical force-measuring plate 4 with permeable holes 3 is placed above the cuboid soil sample, and a vertical dial indicator 5 is in close contact with the vertical force-measuring plate 4 and is perpendicular to it.

[0021] On the left and right side walls of the cuboid soil sample, there are horizontal force measuring plates 7 that can move outward along the normal direction of the two side walls with the expansion of the soil sample. The permeable hole 3 is provided wi...

Abstract

The invention discloses a dilatometer. The dilatometer at least comprises a base, a container arranged on the upper side of the base, a vertical dial indicator and a horizontal dial indicator, wherein the container consists of a base plate and a side wall; a cuboid soil sample is arranged in the container; a vertical force measurement plate is arranged on the upper side of the cuboid soil sample; a horizontal force measurement plate capable of moving along the normal direction of more than one side wall of the cuboid soil sample with the dilation of the soil sample is leaned on the side wall; the vertical dial indicator and the vertical force measurement plate are contacted with each other tightly and vertical to each other; and the horizontal dial indicator passes through a dial indicator insertion hole formed in the side wall of the container and is contacted with the horizontal force measurement plate tightly and vertical to the horizontal force measurement plate. By the dilatometer, a user can observe the dilated deformation of the soil sample in vertical and horizontal directions at the same time.

Description

technical field [0001] The invention relates to a dilatometer. Background technique [0002] Existing dilatometers for measuring the expansion deformation of cylindrical soil samples can only observe the vertical expansion deformation of the soil sample, but cannot measure the horizontal expansion deformation of the soil sample. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a dilatometer. The dilatometer provided by the present invention can simultaneously observe the vertical and horizontal expansion deformation of a soil sample. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a dilatometer at least includes a base, a container placed above the base, a vertical dial gauge and a horizontal dial gauge, the container is composed of a bottom plate and a side wall, and the cuboid soil The sample is placed in a container, a vertica...
