Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
It should be noted that, in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention but do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1, be the utility model discloses overall structure schematic diagram, a spiral foundation ditch horizontal displacement observation device, including observation pole and monitoring nail, the observation pole is including the observation pole body of rod 7, and 7 bottom fixedly connected with of observation pole body of rod are used for observing the back taper observation body 6 of work, and 6 bottom fixedly connected with observation pole screw rods 5 of back taper observation body, specifically as shown in fig. 4, be the observation pole bottom view.
Monitoring nail is including the monitoring nail body of rod 3, and 3 tops of monitoring nail body of rod are equipped with monitoring nail inside screw hole 4, monitoring nail inside screw hole 4 degree of depth and 5 length looks adaptations of observation pole screw rod, and monitoring nail inside screw hole 4 degree of depth equals with 5 length looks adaptations of observation pole screw rod promptly, and monitoring nail inside screw hole 4 external diameters and 5 external diameter looks adaptations of observation pole screw rod to realize that observation pole and monitoring nail threaded connection are specifically as shown in figure 5 and figure 6, do respectively the monitoring nail threaded hole with observation pole screw rod constructional view.
When an observer screws the observation rod screw 5 into the threaded hole 4 in the monitoring nail, observation can be carried out through the inverted cone observation body 6; the observation rod is small in size and can be carried about, so that the original centering time is omitted; compared with the connection mode of the centering rod frame to the monitoring nail in the prior art, the threaded connection mode has higher stability, and is favorable for improving the observation precision; in order to further improve the connection stability between the observation rod and the monitoring nail, the depth of the threaded hole 4 in the monitoring nail is 5 to 10 times of the diameter of the monitoring nail.
