Keep heat-conducting member 2 and temperature sensor 4 all to be located outside soil moisture sensor 5's detection area through non-metallic body 1, make the distance between two sensors fixed, avoid the too near production of distance of two sensors to disturb, the installation gesture of two sensors of adjustment when can also be convenient. In the detection process, temperature sensor 4 installs on temperature sensor installation position 21, and heat conduction member 2 can be with the heat transfer of near soil for temperature sensor 4, reduces because of nonmetal main part 1 blocks the contact of soil and temperature sensor 4, the temperature measurement precision that leads to descends.

Referring to fig. 3 to 5, as a specific embodiment of the measuring assembly provided by the present invention, the measuring assembly includes more than two soil moisture and temperature sensor combined brackets, the measuring assembly further includes a fixing rod 3, a through hole is axially disposed in the fixing rod 3, two ends of the fixing rod 3 are respectively formed with a socket 31 for being socket-connected with the non-metal main body 1 by the through hole, and a threading port 32 communicated with the through hole is further disposed on a side wall of a lower end of the fixing rod 3. By adopting the structure, the installation of the sensors of monitoring points at different depths at the same position can be simplified. When the device is used, the fixing rod 3 is connected between the soil moisture and temperature sensor combined support, after the two soil moisture and temperature sensor combined supports are buried in the measuring hole, the depth difference of the two soil moisture and temperature sensor combined supports can be accurately kept, and the monitoring on the soil with different depths is realized. When the device is used, a plurality of soil moisture and temperature sensor combined brackets provided with sensors can be sequentially connected in series from top to bottom through the fixing rod 3, so that the sensors can be sent to different depths of a single measuring hole, and the soil at the different depths of the measuring hole can be monitored; through the length of control dead lever 3, can realize the accurate control of the inside sensor degree of depth of soil.

Specifically, the fixing rod 3 may be a square tube, the tube hole is a through hole, and the openings at both ends of the square tube form the sockets 31, respectively. The fixing rod 3 may be made of metal or nonmetal. The length of the fixed rod 3 is determined according to the depth difference of two monitoring points in the same measuring hole. The threading opening 32 may be plural, and specifically, may be provided on a side wall of the lower end of the fixing lever 3 facing the wiring groove 131 and a side wall facing the heat guide 2, respectively. The connection line of the soil moisture sensor enters the threading opening 32 along the wiring groove 131.

In particular, the construction method can comprise the following steps:

1. construction of earthwork

According to the design, the sensor embedding position on the construction drawing is measured and lofted and positioned on the spot, and a drilling machine is used for drilling a measuring hole on the ground, wherein the depth of the measuring hole is not less than the depth of the deepest sensor embedding position.

2. Assembly measuring assembly

And manufacturing a fixed rod 3 with corresponding length according to the depth difference of the sensor embedding positions in the same measuring hole. A plurality of soil moisture and temperature sensor combined brackets are connected in series by utilizing the fixing rod 3, so that the distance between the adjacent soil moisture and temperature sensor combined brackets is the same as the depth difference of the embedding position of each sensor in the same measuring hole. The temperature sensor 4 is installed on the temperature sensor installation position 21, the soil moisture sensor 5 is installed on the soil moisture sensor installation position 121, and connecting wires of the sensors penetrate through the through hole of the fixing rod 3 and are led out from one end, close to the ground, of the fixing rod 3.

4. Backfill measuring hole

And inserting the assembled measuring assembly into the measuring hole, ensuring that each sensor is at a preset depth, backfilling according to an original soil layer, tamping a part of the soil layer at a certain height, and tamping while backfilling until the soil layer is backfilled to the ground height to finish construction.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
