Detailed Description
In order to make the technical field person understand the solution of the present invention better, the technical solution of the present invention is further described below with reference to the specific embodiments.
The device comprises a pipe hoop 1 and a hoop cap 2, both of which are made of ferrous materials.
The pipe hoop 1 is integrally in a hollow cylinder shape, the wall thickness of the pipe hoop is about 4mm, two convex welding parts 1-1 used for being welded on a steel wall are arranged on two outer sides of the pipe hoop, the welding parts 1-1 are sheet-shaped, the thickness of the welding parts is about 2mm, and the length of the welding parts is consistent with that of the pipe hoop; internal threads 1-2 are arranged on the inner walls of the upper and lower ports of the pipe hoop 1, grooves 1-3 which are correspondingly matched with the outer wall of the inclinometer and penetrate through the pipe hoop from top to bottom are formed in the inner wall of the pipe hoop, and screw holes 1-4 are reserved on the periphery of the pipe hoop so as to fix the two connected inclinometers. Furthermore, the number of the grooves 1-3 is 4, and the bearing circumferences are distributed at equal intervals.
The hoop cap 2 is conical, the outer diameter of the hoop cap is the same as that of the pipe hoop 1, so that friction force between the hoop cap and a soil body is reduced when the hoop cap is arranged at the lowest end and is driven together with a carrier, the top end of the hoop cap 2 is provided with an external thread buckle 2-1, the outer diameter of the external thread buckle is the same as the inner diameter of the pipe hoop 1, and the external thread buckle can be matched with the internal thread 1-2 of the pipe hoop so as to be fixed.
As shown in fig. 3, the a-a groove for monitoring is parallel to the welded portion to ensure that the inclinometer placed at the time of the final measurement is perpendicular to the measurement surface.
The specific method for installing the inclinometer by using the device is as follows:
① measuring and marking a line on the carrier to be monitored to ensure that all the pipe clamps 1 are mounted in a line;
②, calculating the distance according to the length of the inclinometer, and sequentially welding the pipe hoop 1 on the carrier in a mode of fully welding two welding parts 1-1 to ensure the firmness of the two welding parts;
③ after the pipe hoop is cooled, the inclinometer pipes 3 are sequentially inserted into the pipe hoop 1, the pipe heads of two adjacent inclinometer pipes 3 are butted through the pipe hoop 1, self-tapping screws are used for fixing the pipe heads on the pipe hoop (see figure 4), the fixed convex grooves on the outer wall of the inclinometer pipes are completely combined with the grooves on the inner wall of the pipe hoop (see figure 5), and the whole inclinometer pipes are ensured not to be twisted and deformed during vibration driving;
④ after the inclinometer pipe is completely installed, the pipe hoops 1 at the top and bottom are respectively screwed into hoop caps 2, and finally are driven into the soil body along with the carrier, during the driving process, the hoop cap at the lower end can play the role of reducing resistance and protecting the end head, and the hoop cap at the upper end can ensure that the inclinometer pipe cannot move upwards when being subjected to the friction force of the soil body (see figure 6).
