Problems solved by technology

Nowadays, the soil moisture meter can be buried to the test position by means of manual exploration well burial, but there are disadvantages such as long construction period, high cost, poor construction safety, etc., and it cannot be buried when the measured soil is poor in self-support
In addition, due to the lack of installation devices and installation methods in the method of drilling and burying the soil moisture meter, there have been problems such as the inability to accurately install the soil moisture meter to the measured soil layer or poor installation quality.
The backfill of buried holes is mostly loose original soil or sandy soil, without compaction or any waterproof treatment measures. As a result, the permeability of the backfill is much greater than that of the original ground. When the water seeps from top to bottom, it is often buried first. Pores infiltrate into the soil, the test results of the soil moisture meter cannot truly and accurately reflect the infiltration process of the water body and the temporal and spatial variation of the moisture content

Abstract

The invention discloses a soil moisture meter embedding device and embedding method. The device comprises a mounting cylinder, a ramming plate and an operation rod, which can be mounted on the mounting cylinder and can be also mounted on the ramming plate, wherein the operation rod is mounted right above the mounting cylinder so as to form a mounting device; and the operation rod is mounted right above the ramming plate so as to form a rammer; and the method comprises the following steps of: (1) drilling of an embedding hole; (2) water-proof treatment of a data wire joint; (3) mounting of a soil moisture meter: feeding the soil moisture meter to the bottom of the embedding hole by the mounting device and then inserting a probe into a detected soil body downward by using the operation rod; and (4) backfilling of the embedding hole: backfilling the embedding hole in a layered way; and after each layer is backfilled, ramming the backfilled soil body by the rammer. The soil moisture meter embedding device disclosed by the invention has the advantages of simple structure, simplicity and convenience in operation, good use effect and convenience in promotion and application; the soil moisture meter can be accurately mounted to the detected soil layer through drilling the hole; and the real moisture content variation situation of the detected soil layer can be accurately reflected by the soil moisture meter.

Description

technical field [0001] The invention belongs to the technical field of soil moisture detection in geotechnical engineering, and in particular relates to a soil moisture meter embedding device and embedding method. Background technique [0002] Due to poor drainage of the construction site, rainwater seeping into the ground or damage to the water supply and drainage pipes, heating pipes and drainage ditches of the building itself, as well as poor anti-seepage measures for reservoirs and artificial lakes, etc. will cause various leakage problems, sometimes requiring The soil moisture meter is set up to monitor the moisture content change of the foundation soil in real time, which is used for engineering risk assessment and forecasting. The soil moisture meter is a test element that reflects the soil volumetric moisture content by measuring the dielectric constant of the soil. When using it, the probe of the soil moisture meter must first be inserted into the soil to be tested....
