Description

Technical Field

[0001] This application relates to the field of inclinometer installation technology, and in particular to inclinometer buried installation structure. Background Technology

[0002] In building and bridge engineering, due to project scale, design planning, and limited land space, deep foundation pits are typically excavated at the bottom of buildings to meet construction needs. In bridge engineering, cofferdams are used to create waterless spaces for pier and abutment construction, resulting in deep foundation pits. This necessitates ensuring safety during the construction of these deep foundation pits. A crucial task is the monitoring and measurement of these pits. Among these monitoring efforts, the monitoring of deep horizontal displacement is paramount, as it provides the most direct and accurate indication of the displacement changes in the external soil during excavation, thus demonstrating the safety status of the foundation pit. Therefore, the installation of inclinometers and ensuring their long-term reliable operation are critical aspects of foundation pit monitoring.

[0003] In existing technologies, engineering drilling rigs are typically used to drill holes with φ108mm drill bits. After drilling to the predetermined position, the hole walls are flushed with clean water before the drill is lifted to install the inclinometer. However, using engineering drilling rigs has many drawbacks. First, the drilling rig requires a certain amount of working space, and the drilling position must be a certain distance from the retaining structure, generally about 0.5m, which cannot accurately represent the displacement changes of the retaining structure. Second, during the drilling process, due to the use of mud slurry for wall protection and the small hole diameter, coupled with arbitrary mud slurry preparation, hole collapse is highly likely during drilling. Continuous water injection during drilling also leads to local soil collapse at the connection points of the retaining structure, endangering the safety of the foundation pit. Third, the drilling cost is also a considerable expense, and the drilling process is not conducive to safe and civilized construction on site. Fourth, the inclinometer is highly likely to be damaged in the later stages of installation in the soil and cannot be repaired.

[0004] Therefore, it is necessary to propose an installation structure for inclinometer tubes to reduce costs, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a structure for burying and installing inclinometers, which aims to solve the problem of high cost in the prior art of installing inclinometers by drilling holes with a drilling rig.

[0006] To achieve the above objectives, this application proposes an inclinometer installation structure, including:

[0007] Multiple steel pipe piles;

[0008] Locking buckles are installed on steel pipe piles, and two adjacent steel pipe piles are connected by locking buckles.

[0009] The vertical fixing component is installed at the bottom end of the steel pipe pile and has a bearing surface for bearing the inclinometer tube.

[0010] Multiple lateral fixing members are spaced apart on the steel pipe pile, and each lateral fixing member is provided with a limiting groove for the inclined tube to pass through.

[0011] In some embodiments, the transverse fixing member includes: an inner circular segment for forming a limiting groove; and an outer circular segment disposed on both sides of the inner circular segment, the outer circular segment being connected to a steel pipe pile.

[0012] In some embodiments, it further includes a top sealing member disposed at the top end of the inclinometer tube.

[0013] In some embodiments, the device further includes a bottom sealing member disposed at the bottom of the inclinometer tube.

[0014] In some embodiments, the device further includes: a positioning protrusion disposed on the bottom sealing member; and a positioning groove disposed on the bearing surface of the vertical fixing member, the positioning groove being adapted to the positioning protrusion.

[0015] In some embodiments, the device further includes: a connecting pipe, which connects two adjacent inclinometer tubes; and two connecting holes disposed in the connecting pipe.

[0016] This application proposes a structure for installing inclinometer tubes, comprising: multiple steel pipe piles; a locking system, with the locking system installed on the steel pipe piles, connecting adjacent steel pipe piles via the locking system; vertical fixing members, installed at the bottom of the steel pipe piles, with a bearing surface for supporting the inclinometer tube; and multiple horizontal fixing members, spaced apart on the steel pipe piles, each with a limiting groove for the inclinometer tube to pass through. The vertical fixing members are welded to the inner bottom of the steel pipe piles, and the multiple horizontal fixing members are welded to the inner wall of the steel pipe piles at intervals. The inclinometer tube passes through the limiting grooves of the multiple horizontal fixing members, with its bottom aligned with the bearing surface of the vertical fixing member, thus completing the connection between the inclinometer tube and the steel pipe pile. The inclinometer tube is securely installed inside the steel pipe pile, which greatly improves the accuracy of deep horizontal displacement in the foundation pit and is more conducive to guiding on-site foundation pit excavation and support work. The vertical and horizontal fixing members are easy to prefabricate, and the foundation construction site has the corresponding welding conditions, allowing them to be welded into the steel pipe piles relatively quickly. The inclinometer tube installation structure proposed in this application is low in cost and easy to process on-site. Attached Figure Description

[0029] See Figure 1 and Figure 3 As shown, this application proposes an inclinometer installation structure, including: multiple steel pipe piles 8; a locking buckle 9, which is installed on the steel pipe piles 8, and two adjacent steel pipe piles 8 are connected by the locking buckle 9; a vertical fixing member 2, which is installed at the bottom end of the steel pipe piles 8, and the vertical fixing member 2 is provided with a bearing surface for bearing the inclinometer 3; and multiple horizontal fixing members 1, which are spaced apart on the steel pipe piles 8, and the horizontal fixing members 1 are provided with limiting grooves for the inclinometer 3 to pass through.

[0030] The cofferdam is constructed by interlocking steel pipe piles 8 to form a continuous wall in an arc or circle shape. This continuous wall serves to contain water, soil, and sand. The locking mechanism 9 of the steel pipe piles 8 includes a tongue and groove joint on one side and a tenon and mortise on the other side. When two adjacent steel pipe piles 8 are connected, the tongue and groove joint of one steel pipe pile 8 engages with the tenon and mortise of the other, thus forming a connection between the two adjacent piles.

[0031] The vertical fixing component 2 and the horizontal fixing component 1 are prefabricated in the factory. The vertical fixing component 2 is installed at the bottom of the steel pipe pile 8, and multiple horizontal fixing components 1 are spaced apart on the inner side wall of the steel pipe pile 8. The inclinometer tube 3 passes through the limiting groove of multiple horizontal fixing components 1 and its bottom is aligned with the bearing surface of the vertical fixing component 2, thus completing the connection between the inclinometer tube 3 and the steel pipe pile 8.

[0032] Specifically, the vertical fixing component 2 is welded to the inner bottom of the steel pipe pile 8, and multiple horizontal fixing components 1 are welded at intervals to the inner wall of the steel pipe pile 8. The inclinometer tube 3 passes through the limiting grooves of the multiple horizontal fixing components 1, and its bottom is aligned with the bearing surface of the vertical fixing component 2, thus completing the connection between the inclinometer tube 3 and the steel pipe pile 8. The inclinometer tube 3 is firmly arranged inside the steel pipe pile 8, which can greatly improve the accuracy of the deep horizontal displacement of the foundation pit and is more conducive to guiding the on-site foundation pit excavation and support work. The vertical fixing component 2 and the horizontal fixing component 1 are easy to prefabricate, and the foundation construction site has the corresponding construction and welding conditions, so they can be welded into the inside of the steel pipe pile 8 relatively quickly. The inclinometer tube embedding and installation structure of this application is low in cost and convenient for on-site processing.

[0033] In detail, according to the monitoring plan, inclinometer tubes 3 of the corresponding length will be procured. A few extra inclinometer tubes 3 can be prepared to prevent damage during transportation and insufficient length during on-site assembly. Steel pipe piles 8 of the corresponding length will be selected according to the design plan. If one pile is insufficient, multiple steel pipe piles 8 will be welded and cut to form a complete assembly. Vertical fixing components 2 will be welded to the lower part of the steel pipe piles 8. Horizontal fixing components 1 will be welded every 3-5 meters along the axial direction of the inner wall of the steel pipe piles 8. Locking buckles 9 will be fully welded to corresponding positions on both sides of the outer side of the steel pipe piles 8, and the inclinometer tubes 3 will be installed inside the steel pipe piles 8. The planar position of the steel pipe piles 8 will be laid out using a total station, and a rotary drilling rig will be used to drill at the corresponding hole position. The drilling length will be approximately equal to the length of the steel pipe pile 8 to achieve pilot drilling. Good verticality should be maintained during drilling. The steel pipe piles 8 will be lifted using a truck crane or crawler crane and placed into the designated monitoring hole position. A pile driver will then be used to drive the steel pipe piles 8 into the soil. It should be noted that collisions should be avoided during hoisting and insertion / removal to prevent damage to the inclinometer 3. After the steel pipe pile 8 is driven into place, its verticality is checked. If the verticality deviation is too large and cannot be straightened by other means, the steel pipe pile 8 is pulled out, the borehole is backfilled, and a rotary drilling rig is used to re-drill and guide the hole. After the steel pipe pile 8 is driven into place, the excavator is used to remove soil on-site to complete the backfilling of the gaps on the outer wall of the steel pipe pile 8. In this application, the inclinometer 3 and the steel pipe pile 8 are driven into the soil simultaneously, meeting the monitoring start time requirements in the specifications. This avoids monitoring delays caused by factors such as incomplete drilling in the early stages of monitoring, allowing the monitoring work to play a role throughout the entire excavation process and improving the safety factor of the foundation pit excavation.

[0034] Among them, the inclinometer tube 3 is made of two materials: ABS engineering plastic tube and PVC polyvinyl chloride clinker tube.

[0035] See Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the transverse fixing member 1 includes: an inner circular segment for forming a limiting groove; the inner circular segment for fixing the inclinometer tube 3, the inner diameter of which is determined according to the outer diameter of the inclinometer tube 3, and a portion of the inner circular segment having an inner diameter equal to the outer diameter of the inclinometer tube 3. In this application, the outer diameter of the inclinometer tube 3 is 700 mm. An outer circular segment is disposed on both sides of the inner circular segment and connects to the steel pipe pile 8. The curvature of the outer diameter of the outer circular segment is the same as the curvature of the inner diameter of the steel pipe pile 8, so that the outer circular segment can better fit the inner surface of the steel pipe pile 8.

[0036] In this embodiment, the central angle of the inner circular segment is greater than 180° to make the connection between the inner circular segment and the inclinometer tube 3 more reliable and to increase the contact area between the inner circular segment and the inclinometer tube 3, which helps to reduce the risk of the inclinometer tube 3 being damaged by the inner circular segment. The end of the outer circular segment is provided with an arc-shaped surface that adapts to the inner wall of the steel pipe pile 8 to increase the connection strength between the outer circular segment and the steel pipe pile 8.

[0037] See Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, it further includes: a top sealing member 5, which is disposed at the top of the inclinometer tube 3; and a bottom sealing member 4, which is disposed at the bottom of the inclinometer tube 3. The top sealing member 5 is used to seal the top of the inclinometer tube 3, and the bottom sealing member 4 is used to seal the bottom of the inclinometer tube 3, to prevent soil or gravel from falling into the inclinometer tube 3 during the construction of the steel pipe pile 8.

[0038] In this embodiment, the top sealing member 5 is provided with a first columnar body. The outer diameter of the first columnar body is the same as the inner diameter of the inclinometer tube 3. The first columnar body is inserted into the inclinometer tube 3 to enhance the connection strength between the top sealing member 5 and the inclinometer tube 3.

[0039] See Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, it further includes: a positioning protrusion disposed on the bottom sealing member 4; and a positioning groove disposed on the bearing surface of the vertical fixing member 2, the positioning groove being adapted to the positioning protrusion. One end of the bottom sealing member 4 is provided with a second columnar body, the outer diameter of which is the same as the inner diameter of the inclinometer tube 3. The second columnar body is inserted into the inclinometer tube 3. The other end of the bottom sealing member 4 is provided with a positioning protrusion. During the connection process between the inclinometer tube 3 and the steel pipe pile 8, the positioning protrusion of the bottom sealing member 4 is inserted into the positioning groove of the vertical fixing member 2, thereby enhancing the stability of the inclinometer tube 3.

[0040] In this embodiment, the diameter of the positioning protrusion gradually decreases towards the end away from the second column, so that the positioning protrusion can be more easily inserted into the positioning groove.

[0041] See Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the device further includes: a connecting pipe 7, which connects two adjacent inclinometer tubes 3; and two connecting holes disposed on the connecting pipe 7. When the length of the inclinometer tube 3 is insufficient, the two sections of the inclinometer tube 3 need to be connected to meet the length requirement of the inclinometer tube 3. During the connection of the two sections of the inclinometer tube 3, PVC glue is applied to the contact point between the connecting pipe 7 and the inclinometer tube 3 to complete the connection and fix it with screws 6.

[0042] In this embodiment, the bottom sealing member 4 is inserted into the bottom of the lowest inclinometer tube 3. After the inclinometer tube 3 is fixed, it is inserted into the inner wall of the steel pipe pile 8 section by section for installation. This realizes the connection between the steel pipe piles 8.

[0043] Among them, a portion of the transverse fixing component 1 is installed on the connecting pipe 7, and the inner diameter of the inner circular section of the transverse fixing component 1 installed on the connecting pipe 7 is equal to the outer diameter of the connecting pipe 7. Installing the transverse fixing component 1 on the connecting pipe 7 helps to protect the connection between the two inclinometer tubes 3 from damage.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
