Description

Technical Field

[0001] This utility model belongs to the field of caisson construction technology, and in particular relates to a guiding and correction device for caisson sinking. Background Technology

[0002] Caissons are a type of foundation used in underground engineering or deep-buried foundations when open excavation is not feasible due to site or soil strata limitations. The specific construction method involves excavating soil inside the caisson, allowing it to sink to the design elevation under its own weight, overcoming the frictional resistance of the caisson walls. The bottom is then sealed with concrete, and the caisson hole is filled, making it the foundation for bridge piers or other structures. However, during the caisson sinking process, the lack of effective guidance and restraint makes it susceptible to deviations from the intended trajectory due to soil inhomogeneity, groundwater level changes, and various uncertainties during construction. Once deviation occurs, corrective measures are required, which are not only difficult to implement but also severely impact the construction progress. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a guiding and correction device for sinking caissons, which enables the caissons to sink along a set path and corrects the deviation when the caissons sink off course, so as to ensure the verticality of the caissons.

[0004] The technical solution adopted by this utility model is: a guiding and correction device for sinking a caisson, including a ring beam and a clamping and guiding mechanism; the ring beam is arranged around the caisson and has an installation surface on its top; the clamping and guiding mechanism is evenly arranged on the installation surface and includes a limiting wheel and a telescopic adjustment member connected to the limiting wheel. The limiting wheel can roll in the vertical direction and move closer to or away from the caisson under the drive of the telescopic adjustment member.

[0005] Furthermore, the ring beam is set on the soil around the caisson and connected to the clamping and guiding mechanism by pre-embedded bolts.

[0006] Furthermore, the gap between the ring beam and the caisson is set such that the distance between them is no more than 10mm.

[0007] Furthermore, when the cross-sectional shape of the caisson is polygonal, at least two clamping and guiding mechanisms are provided for each sidewall of the caisson.

[0008] Furthermore, the telescopic adjustment component includes a guide, a sliding component, and an adjusting component; one end of the sliding component is slidably connected to the guide, and the other end is connected to the limiting wheel; the adjusting component is connected to the sliding component and is used to drive the sliding component to slide along the length direction of the guide.

[0009] Furthermore, the sliding member has a horizontally oriented groove, and a limiting groove is formed in the groove; the sliding member is slidably disposed in the groove and is equipped with a limiting pin that matches the limiting groove.

[0010] Furthermore, the slide groove is a through groove, and the end of the slide groove away from the limiting wheel is provided with an internal thread, and the adjusting member is provided with an external thread that matches the internal thread.

[0011] Furthermore, the clamping and guiding mechanism also includes a horizontal mounting base, and the guide member is fixed to the horizontal mounting base; the horizontal mounting base is provided with a connecting hole adapted to the pre-embedded bolt, and is fixed to the mounting surface by a leveling nut.

[0012] Furthermore, it also includes a detection component for detecting the verticality of the caisson and a lifting mechanism for lifting the caisson.

[0013] A method for guiding and correcting the trajectory of a caisson during sinking, employing the aforementioned guiding and correcting device for caisson sinking, includes the following steps:

[0014] Excavate the earthwork to the top elevation of the caisson at the predetermined location, level the site, and carry out the concrete foundation construction.

[0015] The cutting edge of the caisson to be constructed;

[0016] Construction of the ring beam and pre-embedded bolts is carried out on the outside of the caisson;

[0017] Install clamping and guiding mechanism;

[0018] Adjust the clamping and guiding mechanism so that the limiting wheel is close to the cutting edge, adjust the verticality of the caisson by the lifting device, and carry out the excavation and hoisting of the soil inside the caisson until the cutting edge of the caisson is submerged below the surface soil layer;

[0019] The caisson wall is raised in sections during construction. At the same time, the verticality and offset of the caisson are observed in real time through a detection component. The lifting mechanism and the clamping and guiding mechanism are then used to correct the deviation.

[0020] The advantages and positive effects of this utility model are:

[0021] (1) By setting up a ring beam and multiple clamping and guiding mechanisms, it can be evenly clamped at different parts of the caisson, so that the caisson sinks according to the set path to ensure the verticality of the caisson; by setting up a lifting mechanism in conjunction with the clamping and guiding mechanism, the caisson can be corrected after it sinks off course; the whole device is easy to use and precise to adjust, which reduces the difficulty of sinking and correcting the caisson and significantly improves the construction efficiency.

[0022] (2) By setting a limiting wheel, the limiting wheel can roll and connect with the side wall of the caisson while pressing against it. This can not only limit the caisson from sinking in the vertical direction, but also reduce the friction between the limiting wheel and the side wall of the caisson and provide a certain support force to the caisson, ensuring that the caisson is evenly supported when sinking and preventing the caisson from shifting laterally.

[0023] (3) By setting up telescopic adjustment components to drive the limit wheel to move closer to or further away from the caisson, the limit wheel can not only press against the side wall of the caisson and apply a set amount of support force to the caisson to avoid lateral displacement during the sinking of the caisson, but also adjust the position of the limit wheel according to the change of the shape of the side wall of the caisson, thus improving the applicability of the device.

[0024] (4) The clamping and guiding mechanism has a simple structure, is easy to manufacture, has reliable connection, and precise adjustment, which ensures the safety of construction and can be reused, thus reducing construction costs. Attached Figure Description

[0031] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0032] Please participate Figures 1 to 4This utility model embodiment proposes a guiding and correcting device for caisson sinking, including a ring beam 1 and a clamping and guiding mechanism 3. The ring beam 1 is arranged around the caisson 2, and its top is provided with a mounting surface. The clamping and guiding mechanism 3 is evenly arranged on the mounting surface, including limiting wheels 35 and telescopic adjustment members 34 connected to the limiting wheels 35. The limiting wheels 35 can roll in the vertical direction and move closer to or away from the caisson 2 under the action of the telescopic adjustment members 34. Through the above technical solution, during the sinking process of the caisson 2, by controlling the telescopic adjustment members 34 to make the limiting wheels 35 press against the side wall of the caisson 2, a uniform support force can be provided to the caisson 2 to accurately guide and limit the caisson 2. When the caisson 2 deviates laterally, the telescopic adjustment members 34 can also adjust the contact between different limiting wheels 35 and the side wall of the caisson 2 and apply different lateral support forces to implement the correction of the caisson 2.

[0033] In this embodiment, the ring beam 1 is set around the periphery of the caisson 2 to be constructed, and is used to fix the clamping guide mechanism 3. The shape of the ring beam 1 is set according to the cross-sectional shape of the caisson 2. Generally, the cross-sectional shape of the caisson 2 can be a circle, a rectangle or other polygons, so the shape of the ring beam 1 is also set to the corresponding shape. Along the thickness direction of the side wall of the caisson 2, the ring beam 1 has a sufficient width to provide a sufficiently large mounting surface for the clamping guide mechanism 3, so that the clamping guide mechanism 3 is stably fixed on the ring beam 1.

[0034] In this embodiment, multiple clamping and guiding mechanisms 3 are evenly arranged around the caisson 2. By clamping different parts of the caisson 2, the caisson 2 sinks along a set path to ensure the verticality of the caisson 2. Each clamping and guiding mechanism 3 abuts against the outer wall of the caisson 2 through a limiting wheel 35 and provides a certain supporting force to the caisson 2. By evenly arranging the clamping and guiding mechanisms 3, it is ensured that the caisson 2 receives uniform supporting force when sinking, preventing the caisson 2 from shifting laterally.

[0035] The aforementioned limiting wheel 35 is a directional roller. During the sinking process, the limiting wheel 35 abuts against the side wall of the caisson 2 and rolls with the side wall of the caisson 2. The rolling direction of the limiting wheel 35 is limited to the vertical direction, which can restrict the sinking of the caisson 2 in the vertical direction to a certain extent and reduce the friction between the limiting wheel 35 and the side wall of the caisson 2.

[0036] The aforementioned telescopic adjustment component 34 is used to drive the limiting wheel 35 to move closer to or further away from the caisson 2. When sinking operations are required, by controlling the telescopic adjustment component 34, the limiting wheel 35 can be pressed against the side wall of the caisson 2, applying a set amount of support force to the caisson 2 to prevent lateral displacement of the caisson 2 during sinking. The position of the limiting wheel 35 can also be adjusted according to the changes in the shape of the side wall of the caisson 2, thus improving the applicability of the device. When the caisson 2 shifts laterally due to soil inhomogeneity, changes in groundwater level, and various uncertainties during construction, the contact and tightness between the limiting wheel 35 and the side wall of the caisson 2 can be adjusted by controlling the telescopic adjustment component 34 at the corresponding position, so as to apply different amounts of support force to the caisson 2 to correct its deviation.

[0037] Furthermore, in this embodiment, the ring beam 1 is set on the soil surrounding the caisson 2 and connected to the clamping and guiding mechanism 3 via pre-embedded bolts 11. During the sinking of the caisson 2, the lateral pressure transmitted by the caisson 2 is transmitted to the ring beam 1 through the clamping and guiding mechanism 3, and further dispersed into the surrounding soil by the ring beam 1, which can effectively avoid excessive local stress leading to soil damage or uneven settlement; the clamping and guiding mechanism 3 is connected to the ring beam 1 via pre-embedded bolts 11, and the two form a stable integral structure that can jointly resist the lateral pressure of the caisson 2; at the same time, this connection method allows for a detachable connection between the clamping and guiding mechanism 3 and the ring beam 1, which is beneficial for the maintenance and reuse of the clamping and guiding mechanism 3.

[0038] Furthermore, in this embodiment, the gap between the ring beam 1 and the caisson 2 is set to be no greater than 10mm. In this embodiment, the cross-sectional shape and size of the caisson 2 are not the same along the height direction, and the maximum position of its cross-section is the cutting edge of the caisson 2. Therefore, the gap between the ring beam 1 and the caisson 2 is controlled by the distance between the inner wall of the ring beam 1 on the side closer to the caisson 2 and the cutting edge of the ring beam 1. By setting the gap between the ring beam 1 and the caisson 2, it can be ensured that the cutting edge structure of the caisson 2 is not blocked by the ring beam 1 during the sinking process, so that the caisson 2 sinks smoothly. It can be understood that when the limiting wheel 35 abuts against the side wall of the caisson 2, the limiting wheel 35 is in a suspended state. By setting the gap between the ring beam 1 and the caisson 2 to be no greater than 10mm, it is beneficial to reduce the suspended length of the limiting wheel 35 and reduce the range of position adjustment of the limiting wheel 35 required by the telescopic adjustment component 34, shorten the force transmission path, and improve the stability and reliability of the clamping guide mechanism 3.

[0039] Furthermore, in this embodiment, when the cross-sectional shape of the caisson 2 is polygonal, at least two clamping and guiding mechanisms 3 are provided for each sidewall of the caisson 2. The polygonal caisson 2 has a relatively long sidewall, allowing each sidewall to be clamped and guided by at least two clamping and guiding mechanisms 3, forming multi-point constraints. This covers a larger area of ​​each sidewall, effectively preventing the caisson 2 from tilting or twisting due to insufficient support at a single point. This helps ensure the vertical sinking of the caisson 2's axis and improves guiding accuracy. It also reduces the lateral pressure of the caisson 2 on a single clamping and guiding mechanism 3, preventing damage from excessive force on a single clamping and guiding mechanism 3, and increasing the upper limit of the lateral pressure of the caisson 2 that the overall clamping and guiding mechanism 3 can withstand.

[0040] Further, in this embodiment, the telescopic adjustment member 34 includes a guide member 32, a sliding member 33, and an adjusting member 34; one end of the sliding member 33 is slidably connected to the guide member 32, and the other end is connected to the limiting wheel 35; the adjusting member 34 is connected to the sliding member 33 and is used to drive the sliding member 33 to slide along the length direction of the guide member 32. The guide member 32 is used to limit the movement direction of the sliding member 33. In use, the length direction of the guide member 32 is made to be horizontal. By controlling the relative position of the sliding member 33 and the guide member 32 through the adjusting member 34, the relative position of the limiting wheel 35 and the side wall of the caisson 2 can be adjusted, so that it applies a set amount of supporting force to the side wall of the caisson 2 to press against the side wall of the caisson 2.

[0041] In one alternative technical solution of the above embodiments, such as Figure 4 As shown, the slider 33 has a horizontally oriented groove 321, within which a limiting groove 322 is formed. The slider 33 is slidably disposed within the groove 321 and is equipped with a limiting pin 331 that matches the limiting groove 322. Through the cooperation between the slider 33 and the groove 321, and between the limiting groove 322 and the limiting pin 331, the slider 33 achieves directional sliding within the groove 321, preventing deflection of the slider 33 during sliding and ensuring that the rolling direction of the limiting wheel 35 remains vertical.

[0042] Based on the above embodiments, this application proposes a specific structure for an optional adjusting member 34: as follows Figure 2As shown, the slide groove 321 is a through groove, and the end of the slide groove 321 away from the limiting wheel 35 is provided with an internal thread. The adjusting member 34 is provided with an external thread that matches the internal thread. Through the above technical solution, the threaded engagement between the adjusting member 34 and the slide groove 321 achieves precise adjustment and self-locking. This not only enables precise adjustment of the position of the sliding member 33, and thus precise adjustment of the position of the limiting wheel 35, but also achieves positioning of the sliding member 33 through self-locking. Specifically, by rotating the adjusting member 34, the length of the adjusting member 34 extending into the slide groove 321 can be adjusted so that its extended end abuts against one end of the sliding member 33, and moves along the slide groove 321 towards the side wall of the caisson 2 under the push of the adjusting member 34. When the limiting wheel 35 abuts against the side wall of the caisson 2, the adjusting member 34 locks and limits the sliding member 33 to prevent the sliding member 33 from moving away from the side wall of the caisson 2 under the side pressure of the caisson 2, thus ensuring the effective support and guidance of the limiting wheel 35 for the caisson 2.

[0043] Furthermore, in this embodiment, the clamping and guiding mechanism 3 further includes a horizontal mounting base 31, on which the guide member 32 is disposed; the horizontal mounting base 31 is provided with a connecting hole adapted to the pre-embedded bolt 11, and is fixed to the mounting surface by a leveling nut. In this embodiment, the horizontal mounting base 31 is used to install the guide member 32, and its installation angle directly affects the extension direction of the guide member 32. By setting leveling nuts on the upper and lower surfaces of the horizontal mounting base 31, the levelness of the horizontal mounting base 31 can be precisely controlled, thereby adjusting the extension direction of the guide member 32 and ensuring that the rolling direction of the limiting wheel 35 meets the requirements for guiding the sidewall of the caisson 2.

[0044] Specifically, in the above embodiment, the horizontal mounting base 31 includes a horizontal plate and a vertical plate. Four connecting holes are evenly arranged on the horizontal plate and fixed to the mounting surface of the ring beam 1 by leveling nuts and pre-embedded bolts 11. The vertical plate is vertically arranged in the middle of the horizontal plate, and the guide member 32 is arranged on the upper part of the vertical plate. The two are arranged with equal length to form a stable support for the guide member 32, thereby ensuring that the clamping guide mechanism 3 can effectively play its guiding role.

[0045] Furthermore, in a specific embodiment, the guiding and correcting device for sinking the caisson 2 proposed in this application also includes a detection component for detecting the verticality of the caisson 2 and a lifting mechanism for lifting the caisson 2. When the detection component detects that the caisson 2 has deviated, the lifting mechanism applies an upward lifting force to the caisson 2, and at the same time applies a supporting force to the set position of the deep well by adjusting the limiting wheel 35. This can more conveniently and efficiently complete the correction of the caisson 2. Through the above technical solution, the problem of high correction difficulty caused by a large deviation of the caisson 2 can be solved more effectively.

[0046] Specifically, the detection component can be any device capable of detecting the verticality and offset of the caisson 2. For example, the detection component may include several vertical spirit levels installed on the side wall of the caisson 2, allowing construction personnel to easily observe the degree of tilt of the caisson 2; it may also include a plumb line, which can accurately measure the specific value of the tilt. The lifting mechanism is connected to the caisson 2 via a pull ring 21 installed at the top of the caisson 2.

[0047] This application also proposes a guiding and correction construction method for caisson sinking, which uses the guiding and correction device for caisson sinking in the above embodiments, and includes the following steps:

[0048] S1. Excavate the earthwork at the preset location to the top elevation of caisson 2, level the site, and carry out the concrete foundation construction.

[0049] S2, the cutting edge of the construction caisson 2;

[0050] S3. Construct the ring beam 1 and pre-embedded bolts 11 on the outside of the caisson 2;

[0051] Specifically, the planned construction position of the caisson 2 is located by measuring and setting out lines, and the distance between the ring beam 1 and the outline is set within 10mm according to the maximum cross-sectional outline of the cutting edge of the caisson 2. The outline of the ring beam 1 is then laid out, followed by the formwork erection and steel reinforcement binding. Pre-embedded bolts 11 are installed at the set position, and the concrete of the ring beam 1 is poured.

[0052] S4. Install clamping guide mechanism 3;

[0053] Specifically, the clamping guide mechanism 3 includes a horizontal mounting base 31, a limiting wheel 35, and a telescopic adjustment component 34. The horizontal mounting base 31 includes a horizontal plate and a vertical plate. The horizontal plate has a connection hole adapted to the pre-embedded bolt 11, and the vertical plate is welded vertically to the horizontal plate. The telescopic adjustment component 34 includes a guide component 32, a sliding component 33, and an adjusting component 34. The guide component 32 is welded to the upper end of the vertical plate, the limiting wheel 35 is disposed at one end of the guide component 32, the other end of the guide component 32 is slidably connected to the slide groove 321 of the guide component 32, and the adjusting component 34 is threadedly connected to the other end of the slide groove 321. The horizontal mounting base 31 is installed on the mounting surface of the ring beam 1 by leveling bolts, ensuring that the horizontal plate is in a horizontal state and the limiting wheel 35 can roll in the vertical direction.

[0054] In this embodiment, the limiting wheel 35 adopts a rolling steel core nylon wheel and a double-sided ball bearing, which has good compressive strength and wear resistance.

[0055] S5. Adjust the clamping guide mechanism 3 so that the limit wheel 35 is in close contact with the cutting edge of the caisson 2. Adjust the verticality of the caisson 2 through the lifting device, and carry out the excavation and hoisting of the soil inside the caisson 2 until the cutting edge of the caisson 2 is submerged below the surface soil layer.

[0056] S6. The caisson 2 wall is raised in sections. At the same time, the verticality and offset of the caisson 2 are observed in real time through the detection component. Then, the lifting mechanism and the clamping guide mechanism 3 are used to correct the deviation.

[0057] In this embodiment of the application, the detection component includes several vertical spirit levels and a plumb line. In steps S5 and S6, the operator observes the verticality of the caisson 2 using the vertical spirit levels. When it is found that the caisson 2 is tilted to one side, the offset value is determined by the plumb line. Then, the lifting mechanism set at the top of the caisson 2 applies an upward lifting force to the caisson 2. Subsequently, the limiting wheel 35 corresponding to the higher side of the caisson 2 is controlled to move away from the side wall of the caisson 2, and the limiting wheel 35 corresponding to the lower side of the caisson 2 is controlled to further press against the side wall of the caisson 2 to apply a greater supporting force to the side wall of the caisson 2 on that side. Finally, with the cooperation of the limiting wheel 35 and the lifting mechanism, the deviation of the caisson 2 is corrected, and the caisson 2 is accurately sunk.

[0058] In this embodiment, in order to facilitate the lifting of the position of the sliding member 33 by the adjusting member 34 so that the limiting wheel 35 can apply sufficient support force to the caisson 2, the end of the adjusting member 34 away from the guide member 32 is also provided with a rotating ring, into which a pry bar can be inserted to drive the adjusting member 34 to rotate.

[0059] The advantages and positive effects of this utility model are:

[0060] (1) By setting up a ring beam and multiple clamping and guiding mechanisms, it can be evenly clamped at different parts of the caisson, so that the caisson sinks according to the set path to ensure the verticality of the caisson; by setting up a lifting mechanism in conjunction with the clamping and guiding mechanism, the caisson can be corrected after it sinks off course; the whole device is easy to use and precise to adjust, which reduces the difficulty of sinking and correcting the caisson and significantly improves the construction efficiency.

[0061] (2) By setting a limiting wheel, the limiting wheel can roll and connect with the side wall of the caisson while pressing against it. This can not only restrict the caisson from sinking in the vertical direction, but also reduce the friction between the limiting wheel and the side wall of the caisson and provide a certain support force to the caisson, ensuring that the caisson receives uniform support force when sinking and preventing the caisson from shifting laterally.

[0062] (3) By setting up telescopic adjustment components to drive the limit wheel to move closer to or further away from the caisson, the limit wheel can not only press against the side wall of the caisson and apply a set amount of support force to the caisson to avoid lateral displacement during the sinking of the caisson, but also adjust the position of the limit wheel according to the change of the shape of the side wall of the caisson, thus improving the applicability of the device.

[0063] (4) The clamping and guiding mechanism has a simple structure, is easy to manufacture, has reliable connection, and precise adjustment, which ensures the safety of construction and can be reused, thus reducing construction costs.
