Problems solved by technology

[0003] At present, the current device for measuring the dissolution test can only complete the dissolution test of fine-grained saline soil indoors. For coarse-grained saline soil, only large-scale devices can be used to do such tests outdoors. Such outdoor tests are time-consuming. power, poor economy

Embodiment Construction

[0025] Such as Figure 1-8 As shown, the embodiment of the present invention provides a novel indoor coarse-grain saline soil dissolution coefficient testing device. The device includes a container 13 with a water outlet for holding saline soil and a loading part arranged on the container 13 . The loading part includes a horizontally arranged loading rod 14 located above, and a pressure bearing rod 21 located below the loading rod 14. The bottom of the pressure bearing rod 21 is provided with a lower surface in contact with the saline soil, which can compress the saline soil down. 41. One end of the loading rod 14 is provided with a movable balance weight 201, and the other end is suspended with a sliding loading weight 202 to realize continuous variable loading. At the designated depth of the test soil sample, a settlement mark 11 is buried near the container wall, and a dial indicator is set on the settlement mark to test the settlement of each soil layer.

Abstract

The invention provides a novel device for testing dissolved settlement coefficient of indoor coarse-grained salty soil. The device comprises a container and a loading part, wherein the container is used for containing salty soil and comprises a water outlet; the loading part is arranged on the container and comprises a loading rod and a pressure-bearing rod; the loading rod is positioned on the upper side and horizontally arranged; the pressure-bearing rod is positioned below the loading rod; a base plate of which the lower surface is contacted with the salty soil and which is capable of downwards compressing the salty soil is arranged at the bottom of the pressure-bearing rod; a movable balance block is arranged at one end of the loading rod, and a sliding type load weight is suspended at the other end of the loading rod so as to realize continuous variable loading; and settlement marks are uniformly distributed at the specified depth of the tested soil sample surrounding the loading plate, and a dial indicator is arranged on the settlement marks for testing the settlement of each soil layer.

Description

technical field [0001] The invention relates to a novel indoor coarse-grain saline soil dissolution coefficient testing device, which belongs to the technical field of indoor testing devices in the field of civil engineering. Background technique [0002] When constructing on various types of foundation soil, the influence of water has always been a factor that cannot be ignored. For the same water soaking conditions, the two foundation soils, loess and saline soil, will have different reactions, that is, loess collapsibility and collapsibility of saline soil. my country's "Building Code for Collapsible Loess Areas" defines that the loess that is wetted by water under a certain pressure, the soil structure is rapidly destroyed, and produces significant additional subsidence is called collapsible loess. Saline soil is soil with a salt content exceeding a certain amount. According to the "Code for Design of Highway Subgrade" of the Ministry of Communications, when the soluble...
