Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 3, the technical solution adopted by the present embodiment is: the device comprises a test bed body and an observation tube; the test bed body adopts a cubic structure; the number of the observation tubes is four; the four observation tubes are symmetrically arranged at four corners of the test bed body; the upper part and the lower part of each observation pipe are sleeved with a fixed ring; the height of the fixed ring is 20mm, the thickness of the fixed ring is 2mm, and a nut with the length of 20mm is embedded; the outer diameter of the observation tube is smaller than the inner diameter of the fixed ring, and a movable space is arranged between the observation tube and the fixed ring; the fixed ring is fixedly connected with the test bed body through the embedded rod; one end of the embedded rod is welded with the fixed ring, and the other end of the embedded rod is embedded into the wall of the test bed body and fixedly connected with the test bed body; the fixed ring is provided with four symmetrically arranged fixed holes; a bolt is arranged in the fixing hole; the bolt is screwed into the fixed ring through the nut and tightly presses the observation pipe, the bolt is an M10 bolt, and the total length of the bolt is 40 cm.
In the specific embodiment, a test bed body is built in a laboratory, four corners of the test bed body are respectively provided with an observation tube, and the upper end and the lower end of each observation tube are fixed in a wall body of the test bed body through a fixed ring and an embedded rod; the horizontal position of the observation pipe can be manually adjusted through the adjusting bolt, so that the observation pipe is inclined, and the displacement of a deep soil body is simulated. Colleges and universities monitor inclination data through special monitoring inclination equipment, training of deep soil displacement monitoring is achieved, and the possibility of training at any time and repeatedly is achieved.
The horizontal position of the observation pipe is adjusted mainly by changing a group of bolts vertical to the direction of the foundation pit; if the PVC pipe moves to the right side, the right bolt is loosened, and then the left bolt is tightened, so that the PVC pipe moves to the right side; a group of bolts parallel to the foundation pit direction mainly play a fastening role, namely, before moving the left direction and the right direction, a group of bolts in the up-down direction are loosened firstly, and after the belt moves in place, a group of bolts in the up-down direction are screwed.
After adopting above-mentioned scheme, this embodiment's beneficial effect does: the method has the advantages that the practical engineering simulation in a laboratory is realized, the relevant monitoring is completed in the laboratory, the influence of the engineering progress, the environment and the like is avoided, and the monitoring can be performed in all weather.
