The present application belongs to the technical field of geotechnical engineering test, and relates to a system and method for rapidly determining the permeability coefficient of low-permeability soil in situ, which comprises an inner sleeve, an outer sleeve, a pressurizing device and a pore water pressure sensor. The inner and outer sleeves are simultaneously driven into the soil to a specified depth, and then the outer sleeve is further pressed to form a sealed test cavity; water is injected into the inner sleeve and the top is closed, and a stable air pressure is applied through the pressurizing hole to accelerate the permeation; the pore water pressure sensor pre-embedded at the bottom of the outer sleeve is used to monitor the transient change data of the pore water pressure at the soil permeation interface in real time and in situ, instead of the traditional external water level change. Based on the monitored pressure decay data, the soil parameters can be calculated. Compared with the prior art, the present application discards the unreliable water level observation link, shortens the test time from several days to several hours, fundamentally avoids the errors introduced by the capillary effect and hysteresis effect, and realizes the rapid and high-precision test of low-permeability soil in situ.

The application relates to a survey scheme planning method and device, electronic equipment and a storage medium, which comprises the following steps: acquiring road network information, the road network information comprising roads and buildings in a target area; dividing the target area into a plurality of survey areas according to the road network information, and determining the operation information of all the survey areas, each operation information comprising an operation type, an operation difficulty and an operation amount; acquiring the business capabilities of a plurality of survey personnel, the business capabilities comprising a plurality of survey fields that can be surveyed by the corresponding survey personnel, and the survey efficiency and the survey level of each survey field; determining a target survey scheme according to the business capabilities of all the survey personnel and the operation information of all the survey areas, and assigning survey areas and survey routes to each survey personnel in the target survey scheme. The application can improve the overall survey efficiency.

This utility model relates to the field of geological engineering technology and discloses a rock and soil breaking device for geological exploration, including a drill bit. Multiple protective shells are fixedly connected to the outer wall of the drill bit. A quick-release mechanism is installed inside each protective shell. A drill rod is slidably connected to the inner wall of the drill bit. A first protective shell is fixedly connected to the outer wall of the drill rod. An adjustment component is installed inside the first protective shell. The quick-release mechanism includes a motor. The outer wall of the first motor is fixedly connected to the inner wall of the protective shell. A gear is fixedly connected to the drive end of the first motor. A fixing column is fixedly connected to the inner wall of the protective shell. A clamping plate is slidably connected to the outer wall of the fixing column. A rack is fixedly connected to the outer wall of the clamping plate. This utility model improves upon the problem of traditional drill bit replacement requiring disassembly of the entire structure, which is time-consuming and labor-intensive. It reduces equipment downtime, lowers the risk of operational delays in field exploration, and improves exploration efficiency.
