Description

Technical Field

[0001] This invention relates to the field of foundation pit support technology, and in particular to a support device for emergency oil tanks and sedimentation tanks. Background Technology

[0002] Oil spill containment tanks and sedimentation tanks are crucial facilities for treating and storing oil spills and sediments, typically requiring support structures to ensure structural stability. Sheet piles are a commonly used support material, favored for their high strength, rapid installation, and relatively low cost. However, in practical applications, the flexibility and adjustability of sheet pile connections still have limitations. For example, most existing sheet pile connections use welding or single-point, single-hole pairing structures on both sides. This connection structure cannot adjust the spacing between the left and right sides, failing to provide flexible adjustment for oil spill containment tanks and sedimentation tanks with complex terrain and irregular shapes. Furthermore, the lateral supports used are usually only composed of steel columns and structural steel sections, fixed together by welding or bolting. While this connection method is robust, it cannot adjust the verticality and support strength of the sheet piles, nor can it correct deformation. Therefore, the adjustment flexibility is poor, limiting its applicability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a support device for accident oil tanks and sedimentation tanks, which can be adjusted laterally with high flexibility, and can also adjust verticality and correct deformation.

[0004] To address the aforementioned technical problems, the present invention provides a support device for an emergency oil tank and a sedimentation and regulating tank, which is installed in the foundation pit of the emergency oil tank and the sedimentation and regulating tank. The device includes a surrounding plate surrounding the foundation pit, a waler assembly connecting the surrounding plates, and a diagonal bracing assembly. The waler assembly is connected to the side of the surrounding plate closest to the emergency oil tank or the sedimentation and regulating tank, and the diagonal bracing assembly is connected between the surrounding plates on adjacent sides of the emergency oil tank or the sedimentation and regulating tank.

[0005] The enclosure panel includes multiple panels and connecting folds symmetrically arranged on both sides of the multiple panels. The multiple panels are connected to the adjacent enclosure panels through the connecting folds. Each connecting fold has at least two protrusions, and a recess is formed between adjacent protrusions. The protrusions can be inserted into the recesses of the adjacent enclosure panels.

[0006] As an improvement to the above solution, the multi-panel is further provided with a first abutting surface, a bending portion and a second abutting surface on both sides. One side of the first abutting surface is directly connected to the multi-panel, the other side of the first abutting surface is connected to one side of the bending portion, the other side of the bending portion is connected to the second abutting surface, and the protrusion and the recess are provided on the second abutting surface.

[0007] As an improvement to the above solution, the first abutting surface and the second abutting surface are parallel to each other, and the first abutting surface, the bent portion and the second abutting surface form an insertion gap, and the second abutting surface can be inserted into the insertion gap of the adjacent surrounding plate.

[0008] As an improvement to the above solution, the waler assembly includes a fixing plate, which is fixed to the side of the enclosure panel. The fixing plate is connected to the multi-panel panel by fasteners, and the cross-section of the fixing plate is H-shaped.

[0009] As an improvement to the above solution, the waler assembly further includes a connecting column, a rotating sleeve, and a support rod. One end of the connecting column is fixedly connected to the fixed plate. One end of the rotating sleeve is provided with a rotating groove. The end of the connecting column away from the fixed plate is inserted into the rotating groove and rotatably connected to the rotating sleeve. The other end of the rotating sleeve is provided with a sliding groove. The sliding groove is sleeved outside the support rod. The sliding groove can rotate relative to the support rod. When the sliding groove rotates, it can move axially relative to the support rod.

[0010] As an improvement to the above solution, the sliding groove is provided with an internal thread, the end of the support rod is provided with an external thread, the sliding groove is sleeved on the outside of the support rod and engages with the external thread of the support rod, the outer side of the rotating sleeve is provided with a first handle, and the outer side of the support rod is provided with a second handle.

[0011] As an improvement to the above solution, the diagonal bracing assembly includes a diagonal brace and an end plate. The end plate is disposed at both ends of the diagonal brace and connected to the fixing plate. The diagonal brace is connected between the fixing plates on adjacent sides of the foundation pit.

[0012] As an improvement to the above solution, the end plate is inclinedly connected to the diagonal brace, and a support spring is provided in the acute-angle space formed by the end plate and the diagonal brace. One end of the support spring is connected to the end plate, and the other end is connected to the diagonal brace.

[0013] As an improvement to the above solution, the top of the enclosure protrudes from the ground, the bottom of the enclosure is inserted below the foundation pit, and the height of the enclosure inserted below the foundation pit is at least 1 / 2 of the total height of the enclosure.

[0014] As an improvement to the above solution, a protective net is also included, which is installed around the foundation pit and located on the side of the enclosure away from the foundation pit.

[0015] Implementing this invention has the following beneficial effects:

[0016] The present invention provides a support device for emergency oil tanks and sedimentation tanks, comprising a surrounding plate, a waler assembly, and a diagonal brace assembly. The surrounding plate includes multiple panels and connecting folds symmetrically arranged on both sides of the multiple panels. Each connecting fold has at least two protrusions, with a recess formed between adjacent protrusions. The protrusions can be engaged in the recesses of adjacent surrounding plates. Both protrusions can be engaged in the recesses, and different protrusions engaging in the recesses will produce different lateral distances. Therefore, the distance between the two surrounding plates can be adjusted laterally, providing high flexibility and adapting to more complex terrains and irregularly shaped oil tanks and sedimentation tanks.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0024] See Figure 1 and Figure 2This invention discloses a support device for emergency oil tanks and sedimentation regulating tanks, which is installed in the foundation pit 5 of the emergency oil tank and sedimentation regulating tank. In use, before constructing the emergency oil tank or sedimentation regulating tank, the foundation pit 5 is excavated first, and then support and protection are provided around the foundation pit 5. The support device for emergency oil tanks and sedimentation regulating tanks includes a surrounding plate 1 surrounding the foundation pit 5, a waler assembly 2 connecting the surrounding plates 1, and a diagonal brace assembly 3. The surrounding plate 1 is used for the stability of the foundation pit 5 and to prevent soil collapse. The waler assembly 2 and the diagonal brace assembly 3 are used to improve the stability and strength of the surrounding plate 1. The waler assembly 2 is connected to the side of the surrounding plate 1 closest to the emergency oil tank or the sedimentation regulating tank to support the inner side of the surrounding plate 1. The diagonal brace assembly 3 is connected between the surrounding plates 1 on the adjacent sides of the emergency oil tank or the sedimentation regulating tank to strengthen the connection between adjacent surrounding plates 1. The enclosure panel 1 includes multiple panels 11 and connecting folds 12 symmetrically arranged on both sides of the multiple panels 11. The multiple panels 11 are composed of multiple different planes or curved surfaces. The multiple panels 11 are connected to the adjacent enclosure panels 1 through the connecting folds 12. The connecting fold 12 on the left can be connected to the connecting fold 12 on the right side of the enclosure panel 1 located to its left, and the connecting fold 12 on the right can be connected to the connecting fold 12 on the left side of the enclosure panel 1 located to its right. In order to adjust the connection length on the left and right sides, the connecting fold 12 includes at least two protrusions 121, and a recess 122 is formed between adjacent protrusions 121. When assembled, the angles of adjacent partition plates 1 differ by 180°, so that the protrusions 121 can be inserted into the recesses 122 of adjacent partition plates 1. The protrusions 121 that are inserted into the recesses 122 of adjacent partition plates 1 can be protrusions 121 closer to the partition plate 1 or protrusions 121 farther away from the partition plate 1. Therefore, the distance between two adjacent partition plates 1 can be adjusted by inserting protrusions 121 at different positions, thereby achieving the effect of adjusting the side distance.

[0025] The beneficial effects of the embodiments of the present invention are as follows:

[0026] The support device for accident oil tanks and sedimentation tanks in this embodiment of the invention includes a surrounding plate 1, a waler assembly 2, and a diagonal brace assembly 3. The surrounding plate 1 includes a multi-panel 11 and connecting folding blocks 12 symmetrically arranged on both sides of the multi-panel 11. Each connecting folding block 12 has at least two protrusions 121, and a recess 122 is formed between adjacent protrusions 121. The protrusions 121 can be inserted into the recesses 122 of adjacent surrounding plates 1. Both protrusions 121 can be inserted into the recesses 122. Different protrusions 121 inserted into the recesses 122 will produce different lateral distances, so the distance between the two surrounding plates 1 can be adjusted laterally. The adjustment is highly flexible and can adapt to more oil tanks and sedimentation tanks with complex terrain and irregular shapes.

[0027] Specifically, see Figure 3 The multi-panel 11 is further provided with a first abutting surface 13, a bending portion 14, and a second abutting surface 15 on both sides. One side of the first abutting surface 13 is directly connected to the multi-panel 11, and the other side of the first abutting surface 13 is connected to one side of the bending portion 14. The other side of the bending portion 14 is connected to the second abutting surface 15. The first abutting surface 13 and the bending portion 14 are connected at a certain angle, and the bending portion 14 and the second abutting surface 15 are connected at a certain angle. The protrusion 121 and the recess 122 are provided on the second abutting surface 15. In this way, when the adjacent side panel 1 is rotated 180°, its protrusion 121 can be inserted into the recess 122 of the side panel 1.

[0028] In this embodiment, to effectively limit the positioning of the enclosure panel 1, the first abutment surface 13 and the second abutment surface 15 are parallel to each other. The first abutment surface 13, the bent portion 14, and the second abutment surface 15 form an insertion gap 16, allowing the second abutment surface 15 to be inserted into the insertion gap 16 of adjacent enclosure panels 1. The first abutment surface 13 and the second abutment surface 15 restrict the movement of the enclosure panel 1 in the front-back direction, and the cooperation of the protrusion 121 and the recess 122 restricts the movement of the enclosure panel 1 in the left-right direction, thus achieving better fixation. Furthermore, the first abutment surface 13 and the second abutment surface 15 extend the seepage channel, achieving a better waterproofing effect.

[0029] Further, see Figure 4The waler assembly 2 includes a fixing plate 21, which is fixed to the side of the enclosure panel 1, specifically located on the inner side of the enclosure panel 1, i.e., the side closest to the foundation pit 5. The fixing plate 21 is connected to the multi-panel panel 11 by fasteners, which can be standard parts such as bolts. The fixing plate 21 has an H-shaped cross-section. The connection of the fixing plate 21 to the inner side of the enclosure panel 1 enhances the stability of the connection between the enclosure panels 1.

[0030] During use, the enclosure 1 may deform or bend due to increased soil pressure caused by construction or other reasons. Its verticality may change, and the protrusions and recesses 122 may loosen, thereby changing the overall shape of the enclosure 1 and affecting the stability of the entire support device. To address the aforementioned issues, the waler assembly 2 further includes a connecting column 22, a rotating sleeve 23, and a support rod 24. One end of the connecting column 22 is fixedly connected to the fixing plate 21, and the fixing plate 21 moves axially along with the connecting column 22. One end of the rotating sleeve 23 is provided with a rotating groove 231. The end of the connecting column 22 away from the fixing plate 21 is inserted into the rotating groove 231 and rotatably connected to the rotating sleeve 23. Therefore, the rotating sleeve 23 is fitted over the connecting column 22. To improve the connection strength between the rotating sleeve 23 and the connecting column 22, a central column 233 is provided in the rotating groove 231. The central column 233 can be inserted into the connecting column 22 to form a coaxial rotatable connection. Therefore, the rotating sleeve 23 forms an internal and external rotatable connection with the connecting column 22 through the rotating groove 231, the central column 233, and the connecting column 22, thereby strengthening the overall connection strength. The support rod 24 is connected to the fixed plate 21 through the rotating sleeve 23 and the connecting column 22. Therefore, the support rod 24 is mainly used to support the surrounding plates 1 on opposite sides. The other end of the rotating sleeve 23 is provided with a sliding groove 232. The sliding groove 232 is sleeved on the outside of the support rod 24. The sliding groove 232 can rotate relative to the support rod 24. When the sliding groove 232 rotates, it can move axially relative to the support rod 24. When the sliding groove 232 moves axially, it will drive the connecting column 22 to move axially through the rotating sleeve 23, thereby affecting the supporting force generated by the fixed plate 21 on the inner side of the surrounding plate 1. By increasing the supporting force generated by the fixed plate 21 on the surrounding plate 1, the deformation of the surrounding plate 1 or the bending caused by the increase of soil pressure can be improved.

[0031] Specifically, the sliding groove 232 has an internal thread, and the end of the support rod 24 has an external thread. The sliding groove 232 is sleeved on the support rod 24 and engages with the external thread of the support rod 24. By rotating the sliding groove 232, the engagement between the external and internal threads will cause the sliding groove 232 and the support rod 24 to move axially. The rotating sleeve 23 also includes a blocking part 235, which is disposed on the outer wall of the sliding groove 232. The length L of the blocking part 235 is greater than the total arrangement length S of the external thread of the support rod 24. In this way, no matter what position the rotating sleeve 23 is in relative to the support rod 24, the blocking part 235 can block the external thread of the support rod 24, which can prevent water and dust from entering and prevent the external thread of the support rod 24 from rusting or becoming blocked.

[0032] To prevent the support rod 24 from rotating, a first handle 234 is provided on the outer side of the rotating sleeve 23, and a second handle 241 is provided on the outer side of the support rod 24. By fixing the second handle 241 and rotating the first handle 234, it can be ensured that only the sliding groove 232 rotates and the support rod 24 does not rotate.

[0033] Additionally, preferably, see Figure 5 The enclosure panels 1 form a rectangular space, and the diagonal bracing assembly 3 connects the enclosure panels 1 on adjacent sides of the pit 5 by an inclined connection to enhance the compressive strength of the adjacent enclosure panels 1. The diagonal bracing assembly 3 includes a diagonal bracing rod 31 and an end plate 32. The end plate 32 is located at both ends of the diagonal bracing rod 31 and is connected to the fixing plate 21. The enclosure panels 1 on the same side of the pit 5 are fixedly connected to the same fixing plate 21, while the fixing plates 21 on adjacent sides are connected at right angles. The diagonal bracing rod 31 connects the fixing plates 21 on adjacent sides of the pit 5, thereby enhancing the compressive strength of the adjacent enclosure panels 1. Furthermore, the end plate 32 is inclinedly connected to the diagonal bracing rod 31, and a support spring 33 is provided in the acute angle space formed by the end plate 32 and the diagonal bracing rod 31. One end of the support spring 33 is connected to the end plate 32, and the other end is connected to the diagonal bracing rod 31. The support spring 33 provides better support for the diagonal brace 31 and the end plate 32, thereby enhancing the compressive strength of the fixed plate 21.

[0034] See Figure 6The bottom of the pit 5 is below ground level, while the top of the retaining wall 1 protrudes above ground level. The bottom of the retaining wall 1 is inserted below the pit 5, and the height h of the retaining wall 1 inserted below the pit 5 is at least 1 / 2 of the total height H of the retaining wall 1, to ensure that the retaining wall 1 has good supporting strength and bending strength. The support device for the emergency oil tank and sedimentation tank also includes a protective net 4, which is installed around the pit 5 and located on the side of the retaining wall 1 away from the pit 5. The protective net 4 is used to protect the outer side of the portion of the retaining wall 1 that protrudes above ground level.

[0035] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
