Please refer to Figure 1 and Figure 2, the base 100 is used to be fixed to the foundation. The precast conduit member 200 is installed on the base 100. The functional sleeve 300 is provided with a cylindrical part 310 and an elastic element 320. The cylindrical part 310 is movably sleeved outside the precast conduit member 200. The elastic element 320 is inserted through the cylindrical part 310 and is connected to the precast conduit member 200. During the construction of the roller, the elastic element 320 can resist the instantaneous impact during the rolling of the roller. The elastic element 320 and the cylindrical part 310 outside it together protect the precast conduit member 200 from being damaged by rolling. After the roller passes, the elastic element 320 can recover and make the cylindrical part 310 expose above the foundation surface to cooperate with the level for settlement observation.

[0033] In order to solve the problem that the monitoring data measurement is inaccurate caused by the sand and gravel easily invading into the opening of the precast conduit member 200 through the connection between the functional sleeve 300 and the precast conduit member 200 under the influence of settlement, the present application further designs the precast conduit member 200 and the functional sleeve 300, and the specific description is as follows.

[0034] Please refer to Figure 3 , the precast conduit member 200 is provided with a pipe part 210 and a head part 220. The head part 220 is connected to one end of the pipe part 210 in terms of length. The head part 220 is connected to the base 100, specifically, the end of the head part 220 far from the pipe part 210 is connected to the base 100; the head part 220 and the base 100 can adopt a detachable connection method, which is convenient for on-site assembly and disassembly; please specifically refer to Figure 4 , the pipe part 210 is provided with at least one chute 211. The chute 211 is distributed along the axial direction of the pipe part 210. The chute 211 is opened on the outer side of the pipe body of the pipe part 210. The chute 211 can be understood in the form of an open groove, and it is defined that the chute 211 is spaced from the end of the pipe part 210 far from the head part 220, that is to say, the chute 211 does not penetrate Figure 4 the upper end of the pipe part 210 in , thus providing a structural basis for realizing the anti-detachment function at the end of the pipe part 210 far from the head part 220. The method for realizing the anti-detachment function will be specifically described in combination with the structure of the functional sleeve 300.

[0035] Please refer to Figure 3, the barrel portion 310 of the functional sleeve 300 is movably sleeved outside the pipe portion 210. The barrel portion 310 has a barrel cavity which presents as a blind hole shape. The orifice of the barrel cavity is located at one axial end of the barrel portion 310. The barrel cavity is formed by enclosing the cavity wall of the barrel portion 310. The cavity wall of the barrel portion 310 includes a bottom wall and a peripheral wall. The elastic element 320 of the functional sleeve 300 is inserted through the barrel cavity. One end of the elastic element 320 is connected to the head 220, and the other end of the elastic element 320 is connected to the bottom wall of the barrel cavity of the barrel portion 310. The connection here means in contact with each other, which can be a fixed connection, a separable contact, or other connection methods. Please refer to Figure 4 , at least one raised chuck 311 is provided on the inner wall of the barrel portion 310. Figure 4 The distribution position of the chuck 311 is specifically shown by the filled parabola in Figure 4 . The chuck 311 is slidably arranged in the chute 211. The chuck 311 and the chute 211 are arranged opposite to each other. At least one chuck 311 is slidably arranged in each chute 211, and the chuck 311 will not disengage from the end of the chute 211 away from the head 220, so as to have the anti-detachment function of preventing the functional sleeve 300 from detaching from the prefabricated conduit member 200.

[0036] In the settlement monitoring device provided in the present application, the prefabricated conduit member 200 and the functional sleeve 300 are specially designed as above. On the one hand, the elastic element 320 inserted through the barrel portion 310 of the functional sleeve 300 is connected to the head 220 of the prefabricated conduit member 200. During the construction of the roller, the elastic element 320 can resist the instantaneous impact during the roller compaction, and can also recover after the roller passes and make the barrel portion 310 expose above the foundation surface to cooperate with the level for settlement observation. On the other hand, the chuck 311 at the inner wall of the barrel portion 310 of the functional sleeve 300 is slidably arranged inside the chute 211 of the pipe portion 210 of the prefabricated conduit member 200. When the elastic element 320 expands and contracts, it ensures that the chuck 311 is always located in the chute 211, so that the barrel portion 310 of the functional sleeve 300 will not disengage from the pipe portion 210 of the prefabricated conduit member 200, and sand and gravel will not enter the pipe cavity of the pipe portion 210 of the prefabricated conduit member 200 during the working process of the settlement monitoring device, solving the technical problem in the prior art that sand and gravel easily invade the opening of the prefabricated conduit member 200 through the connection between the functional sleeve 300 and the prefabricated conduit member 200, and ensuring the accuracy of the data measurement of the subgrade settlement amount.

[0037] Considering the movement stability when the pipe part 210 and the cylinder part 310 move relative to each other, in some embodiments, the number of the sliding grooves 211 is set to at least two, and all the sliding grooves 211 are evenly spaced along the circumferential direction of the pipe part 210. The cylinder part 310 is provided with the same number of clamping heads 311 as the number of the sliding grooves 211, and all the clamping heads 311 are evenly spaced along the circumferential direction of the cylinder part 310. At least two clamping heads 311 are respectively slidably arranged in at least two sliding grooves 211, and the sliding grooves 211 and the clamping heads 311 adopt a one-to-one corresponding distribution manner.

[0038] In some embodiments, please refer to Figure 3 and Figure 4 , the position of the clamping head 311 on the cylinder part 310 is limited. The clamping head 311 is arranged at the position of the cavity wall opposite to the cavity opening of the cylinder cavity, so that when the settlement monitoring device of the present application works, the maximum allowable movement amount of the clamping head 311 in the clamping groove is in the maximum state, enabling the elastic element 320 to be stretched to the maximum extent, and increasing the maximum value of the subgrade settlement amount that the settlement monitoring device of the present application can measure.

One end of the connecting pipe 130 away from the connection seat 120 is threadedly connected to the head 220. In the threaded connection manner, external threads and internal threads that match each other are provided at the end of the connecting pipe 130 and the head 220.

[0043] In some embodiments, the length direction of the connecting pipe 130 is perpendicular to the settlement base plate 110, and the length direction of the connecting pipe 130 is the same as the axial direction of the pipe portion 210 of the precast conduit member 200 and the axial direction of the barrel portion 310 of the functional sleeve 300, which not only improves the stability of the base 100 but also ensures the accuracy of the measurement results.

[0044] In some embodiments, please refer to Figure 6 , the connecting pipe 130 includes an external thread seat 132, a main body 131, and an internal thread seat 133 that are connected in sequence.

The external thread seat 132 is connected to one end of the length of the main body 131, and the internal thread seat 133 is connected to the other end of the length of the main body 131. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the external thread seat 132 is threadedly connected to the connection seat 120, and the internal thread seat 133 is threadedly connected to the head 220. In this way, by controlling the pipe length of the connecting pipe 130, the overall length of the settlement monitoring device meets the measurement requirements.

[0045] In some embodiments, at least two connecting pipes 130 can be assembled so that the overall length of the settlement monitoring device meets the measurement requirements. At least two connecting pipes 130 in the base 100 are connected in sequence, and the internal thread seat 133 of the previous connecting pipe 130 is threadedly connected to the external thread seat 132 of the next connecting pipe 130.
