Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 3, the present invention provides a technical solution: a subway construction line ground surface settlement monitoring device comprises a buried pipe 1, a settling pipe 2 is sleeved outside the buried pipe 1, an anchor rod 3 is connected with the buried pipe 1 in a sliding mode and a rotating mode in the axial direction and the circumferential direction, a through hole 11 is formed in the bottom of the buried pipe 1, an operation hole 12 is formed in the top of the buried pipe 1, the anchor rod 3 penetrates through the through hole 11 to fix the buried pipe 1 in an anchor pit, the anchor rod 3 extends into the bottom of the anchor pit for a distance to greatly improve the stability of the buried pipe 1 and is not affected by surrounding foundation settlement, namely the buried pipe 1 cannot settle, and when in detection, a measuring device is used for detecting the settlement condition of a subway line by taking the top of the buried pipe 1 as a reference, the bottom of pipe laying 1 still is connected with the cover and establishes the protection uide bushing 4 in 2 bottoms of sedimentation pipe, that is to say when sedimentation pipe 2 slides from top to bottom, protection uide bushing 4 plays the effect of direction, make it can not receive the settlement resistance, wherein, the interior cover of protection uide bushing 4 is equipped with supporting spring 7, this supporting spring 7's effect is to ensure to keep being in the highest position when sedimentation pipe 2 is installed with the anchor pit solidification, a plurality of resistance-increasing recesses 21 have been seted up to the periphery wall of sedimentation pipe 2, behind the concreting between anchor pit and sedimentation pipe 2, the concrete of solidification can extend to in the resistance-increasing recess 21, when the earth's surface subsides avoiding appearing, sedimentation pipe 2 skids.

In this embodiment, the bottom of the anchor rod 3 is provided with one section of helical blade 31, the hexagonal socket head driving groove 32 has been seted up at the top of this anchor rod 3, twist the instrument with the help of the outside and pass through the butt joint of operation hole 12 and hexagonal socket head driving groove 32, then twist, this moment anchor rod 3 utilizes helical blade 31 to lead into in the soil layer of anchor pit bottom, wherein the bottom of anchor rod 3 has been seted up and has been fallen and hinder hole 33, fall and hinder the interior holding soil that is used for of hole 33, reduce the resistance that anchor rod 3 stretches into the soil layer, it is more convenient to install, and is laborsaving, furthermore, the cover is equipped with the commentaries on classics cover 5 that is located buried pipe 1 on anchor rod 3, commentaries on classics cover 5 and the buried pipe 1 inner wall axial sliding connection, wherein the welding of buried pipe 1's top has limiting plate 13, run through the relative stop screw 6 of back one end of screwing and commentaries on classics cover 5 on classics on the limiting plate 13, the quantity of commentaries on classics cover 5 is two, when the bottom commentaries on classics cover 5 moves to the bottom of buried pipe 1 bottom, installation stop screw 6 this moment, stop screw 6 extrudes to the commentaries on classics cover 5, whole anchor rod 3 relatively locks the buried pipe 1 this moment, further, the buried pipe 1's buries.

When the device is used, firstly, an anchor pit is excavated on the ground surface in a line, the device is inserted into the anchor pit in a whole mode, the mouth part of the buried pipe 1 is enabled to be approximately flush with the ground surface, then, the buried pipe is butted with the inner hexagonal driving groove 32 through the operation hole 12 by means of an external screwing tool, then, screwing is carried out, the anchor rod 3 is guided into a soil layer at the bottom of the anchor pit by using the spiral blade 31, the limiting screw 6 is installed at the moment, the limiting screw 6 extrudes the rotating sleeve 5 on the upper surface, the whole anchor rod 3 is locked relative to the buried pipe 1 at the moment, then, concrete is poured between the buried pipe 2 and the anchor pit, the resistance-increasing groove 21 is arranged close to the upper end of the buried pipe 2, after the concrete is solidified, the buried pipe 2 is connected with the surrounding soil layer through the resistance-increasing groove 21, at the moment, when the ground surface subsidence occurs, the buried pipe 2 descends synchronously along with the soil layer with a certain depth below the ground surface, the buried pipe 1 is in a fixed state due to the reason that the fixed depth is deeper, and then, the monitoring equipment is erected at the top of the buried pipe 1 for settlement monitoring.
