Description

Technical Field

[0001] This invention relates to the technical field of enclosure structures, and more specifically, to a method for safe and controlled construction of support structures between enclosure structures. Background Technology

[0002] In deep foundation pit engineering, support structures need to be erected between the retaining structures to balance the lateral earth pressure and control the deformation of the foundation pit. After the support structures are erected and in place, axial prestress needs to be applied to the support structures between the retaining structures so that the support structures enter the bearing state before the foundation pit is excavated, thus eliminating installation gaps.

[0003] In existing construction methods, prestressing is usually achieved by using jacks to push the end of the support. Once the jacks are in place, the prestressing is maintained by the hydraulic system of the jacks themselves. However, some construction methods use filler to lock the jacks in place after they are pushed, but there is no clear division between the steps of applying force and locking.

[0004] During the long construction period of foundation pit excavation, the jacks are under load for a long time, and the hydraulic system is prone to slight backflow, which leads to the gradual loss of prestress. Once the support structure loses its prestress, the installation gap reappears, and the deformation of the retaining structure becomes uncontrollable, thus affecting construction safety. Summary of the Invention

[0023] Reference Figures 1-7 The image shows a preferred embodiment of the present invention.

[0024] The safety-controlled construction method for the supporting structures between the enclosure structures includes the following construction steps: 1) Prepare a hinge head 200 and a supporting steel pipe 300. The hinge head 200 includes a fixed section 500 and a movable section 600 that moves toward or away from the fixed section 500. The movable section 600 and the supporting steel pipe 300 are respectively provided with flanges 400. A jack 201 is provided between the fixed section 500 and the movable section 600. The jack 201 drives the fixed section 500 and the movable section 600 to move toward or away from each other. The jack 201 has a piston shaft 202. 2) Surface treatment is performed on the fixed section 500, the movable section 600 and the supporting steel pipe 300 to form anti-corrosion layers on the surfaces of the fixed section 500, the movable section 600 and the supporting steel pipe 300 respectively. 3) Two steel wain beams 101 are arranged on the enclosure structure 100, and the two steel wain beams 101 are arranged facing each other; 4) Connect the fixed section 500 to a steel waist beam 101, connect the supporting steel pipe 300 to another steel waist beam 101, and connect the two flanges 400 together to form a whole, so that the movable head 200 and the supporting steel pipe 300 are connected to form a whole supporting structure, and the supporting structure is horizontally supported between the two steel waist beams 101. 5) The piston shaft 202 of the jack 201 extends and moves, driving the fixed section 500 and the movable section 600 to move apart, so as to form a jacking stress between the two steel waist beams 101. The jacking stress is applied and arranged along the axial direction of the support structure. 6) Arrange a fixed structure between the fixed section 500 and the movable section 600 to keep the fixed section 500 and the movable section 600 in a relatively fixed state.

[0025] The above-mentioned safe and controlled construction method for the supporting structure between the enclosure structures, through the construction coordination of steps 1 to 6, especially the successive connection of steps 5 and 6, realizes the adjustable application of force and stable maintenance of the supporting stress during the construction process.

[0026] In step 5 of the construction process, the piston shaft 202 of the jack 201 extends and moves, driving the fixed section 500 and the movable section 600 to move apart, forming an axially arranged jacking stress between the two steel waist beams 101. In this way, the extension amount of the piston shaft 202 corresponds to the magnitude of the jacking stress, thereby realizing the adjustable application of the supporting stress.

[0027] In construction step 6, a fixed structure is arranged between the fixed section 500 and the movable section 600 to keep the fixed section 500 and the movable section 600 in a relatively fixed state. In this way, the jacking stress is transferred from the hydraulic support of the jack 201 to the mechanical bearing of the fixed structure, avoiding the loss of prestress caused by the slight backflow of the hydraulic system under long-term load, thereby achieving stable maintenance of the support stress.

[0028] As an extended embodiment, in construction step 2), the anti-corrosion layer includes a primer and a topcoat applied on the primer. The primer includes two layers of red lead paint, which are respectively formed on the surface of the fixed section 500, the surface of the movable section 600, and the surface of the supporting steel pipe 300.

[0029] The anti-corrosion layer is prepared in advance in construction step 2, prior to all subsequent hoisting, docking and prestressing steps; among them, two layers of red lead paint utilize the chemical passivation properties of red lead paint to form a dense passivation film on the surface of the fixed section 500, the movable section 600 and the supporting steel pipe 300, preventing moisture and corrosive media in the foundation pit from penetrating into the steel substrate.

[0030] The topcoat is applied over the primer to provide physical protection for the primer and prevent it from being directly bumped or damaged during subsequent construction steps such as hoisting, docking, and disassembly.

[0031] In this way, the chemical protection of the primer and the physical protection of the topcoat complement each other, achieving comprehensive corrosion protection of the supporting structure throughout the entire construction process and ensuring the long-term durability of the supporting structure.

[0032] As an extended embodiment, in construction step 1), the flange 400 has a mating annular surface 401 and a reversing annular surface 402, with the mating annular surface 401 and the reversing annular surface 402 arranged opposite to each other; the reversing annular surface 402 is provided with a plurality of reinforcing ribs 404, which are evenly spaced around the flange 400 along the circumference and are arranged perpendicular to the flange 400; along the circumference of the flange 400, the flange 400 has a plurality of connecting sections 405, which are arranged sequentially and evenly spaced along the circumference of the flange 400. In construction step 4), the mating ring surfaces 401 of the two flanges 400 are mated together, and bolts 406 are inserted through the connecting section 405. The bolts 406 pass through the connecting section 405 of the two flanges 400 respectively, connecting the two flanges 400 into one unit, so that the movable head 200 and the supporting steel pipe 300 form an integrated support structure.

[0033] In this way, when the supporting structure is subjected to axial pressure, multiple reinforcing ribs 404 simultaneously apply axial constraints to the annular surface 402 away from the flange 400, suppressing out-of-plane deformation of the flange 400; at the same time, multiple connecting sections 405 are evenly distributed circumferentially, and bolts 406 pass through the connecting sections 405 of the two flanges 400 to achieve circumferential fastening, so that the axial pressure is evenly distributed to each connecting section 405 along the circumference of the flange 400, avoiding local stress concentration at the mating position 403, and ensuring the overall rigidity and uniform force transmission of the connection between the swivel head 200 and the supporting steel pipe 300.

[0034] As an extended embodiment, in construction step 3), two brackets 102 are set on the enclosure structure 100, the two brackets 102 are arranged facing each other, and two steel waist beams 101 are arranged on the enclosure structure 100. The steel waist beams 101 are located above the brackets 102 and abut against the brackets 102 from top to bottom. The bracket 102 includes a side frame 103 and a support frame 104 fixed to the enclosure structure 100. The inner end of the support frame 104 is connected to the upper end of the side frame 103, and the outer end of the support frame 104 extends outward away from the enclosure structure 100. An inclined frame 105 is provided between the side frame 103 and the support frame 104. The upper end of the inclined frame 105 is connected to the outer end of the support frame 104, and the lower end of the inclined frame 105 is connected to the lower end of the side frame 103. When the steel waist beam 101 is constructed on the enclosure structure 100, the bottom of the steel waist beam 101 abuts against the support frame 104.

[0035] Thus, the inclined frame 105, the side frame 103, and the support frame 104 together form a triangular support, which applies an oblique tensile force to the outer end of the support frame 104, offsetting the cantilever bending moment caused by the self-weight of the steel waist beam 101 and the supporting structure above it, preventing the outer end of the support frame 104 from drooping in subsequent construction steps, and ensuring that the steel waist beam 101 maintains a stable horizontal posture throughout the construction process, thereby providing an accurate reference surface for the subsequent docking of the flexible head 200 and the supporting steel pipe 300.

[0036] As an extended embodiment, in construction step 4), after the fixed section 500 is fixedly connected to the enclosure structure 100, an inclined fixed suspension rod 501 is connected to the fixed section 500; the fixed suspension rod 501 is located above the fixed section 500; the upper end of the fixed suspension rod 501 is fixedly connected to the enclosure structure 100, and the lower end of the fixed suspension rod 501 is connected to the fixed section 500.

[0037] The fixed suspension rod 501 is arranged between the fixed section 500 and the retaining structure 100, forming an oblique tension transmission path and adding an independent safety constraint. When the subsequent jack 201 drives the movable section 600 to extend or retract or encounters unexpected vibration, if the fixed section 500 tends to sink, the fixed suspension rod 501 bears the tension and transfers the gravity load of the fixed section 500 to the retaining structure 100, thereby preventing the fixed section 500 from falling off and ensuring the connection safety of the fixed section 500 side during construction.

[0038] As an extended embodiment, in construction step 4), after the supporting steel pipe 300 is fixed on the enclosure structure 100, an inclined supporting rod 301 is connected to the supporting steel pipe 300, and the supporting rod 301 is located above the supporting steel pipe 300; the upper end of the supporting rod 301 is fixedly connected to the enclosure structure 100, and the lower end of the supporting rod 301 is connected to the supporting steel pipe 300.

[0039] In this way, the support hanger 301 provides oblique suspension constraint for the support steel pipe 300. For example, during the segmented hoisting and assembly of the steel support, if the support steel pipe 300 is in place but the flange 400 has not yet been connected, the lack of suspension constraint will cause the self-weight of the support steel pipe 300 to cause the flange 400 to sag and deviate, resulting in misalignment of the bolt holes when the two flanges 400 are connected. After forced tightening, the bolts 406 will be subjected to uneven circumferential force, which will then induce local buckling instability of the flange 400 under subsequent axial pressure.

[0040] Therefore, the support rod 301 supports the self-weight of the support steel pipe 300, preventing the support steel pipe 300 from sagging due to its own weight, which would cause misalignment of the holes when the flange 400 is connected. This ensures the alignment accuracy of the two flanges 400 and makes the flange 400 connection surface evenly stressed after the bolts 406 are tightened.

[0041] As an extended embodiment, in construction step 1), the fixed section 500 includes a fixed end plate 502, on which two insert plates 503 are arranged side by side at intervals; the movable section 600 includes a docking section 601, on which a flange 400 is disposed, and on which two guide plates 602 are arranged side by side at intervals, with an interval area 603 formed between the two guide plates 602. The guide plate 602 is provided with a guide groove, and the insert plate 503 is movably inserted into the guide groove; the jack 201 is set in the interval area 603, the jack 201 is connected to the fixed end plate 502, the piston shaft 202 extends toward the docking section 601 and docks with the docking section 601; in construction step 4), the fixed end plate 502 is fixedly connected to a steel waist beam 101; In construction step 5), the piston shaft 202 extends and moves, driving the insert plate 503 to move relative to the guide groove, so as to form a pushing stress between the two steel waist beams 101; in construction step 6), the fixing structure is set in the guide groove to fix the insert plate 503 relative to the guide groove, so that the fixed section 500 and the movable section 600 remain in a relatively fixed state.

[0042] The insertion plate 503, in conjunction with the guide groove, provides directional guidance for the extension process of the movable section 600. When the jack 201 drives the movable section 600 to move, the insertion plate 503 is inserted into the guide groove, which limits the movement trajectory of the movable section 600 and prevents the movable section 600 from swaying or twisting during the extension and contraction process. This ensures that the movable section 600 moves smoothly along the preset axis, making the direction of the jacking stress applied in construction step 5 consistent with the axis of the supporting structure, thereby improving the accuracy of prestressing application.

[0043] Meanwhile, the jack 201 is set in the interval area 603 between the two guide plates 602. The adjacent insert plate 503 and the guide groove form a guide, so that the driving force direction of the jack 201 is consistent with the guiding direction, further reducing the additional bending moment caused by the deviation of the driving force.

[0044] As an extended embodiment, in construction step 1), the inner end of the insert plate 503 is abutted against the fixed end plate 502, and the outer end of the insert plate 503 is inserted into the guide groove to form an insertion end 504; the outer end of the guide groove has an opening facing the outer end of the fixed end plate 502, and the insert plate 503 is inserted into the guide groove through the outer end opening; the inner end of the guide groove forms a closed groove bottom 604, and there is an adjustment interval between the insertion end 504 and the groove bottom 604; In construction step 5), the piston shaft 202 extends and moves, driving the insert plate 503 to move relative to the guide groove, thereby increasing the adjustment interval; in construction step 6), the fixing structure includes a wedge block 605, which is inserted into the adjustment interval. The wedge block 605 abuts against the insertion end 504 and the bottom of the groove 604 to fix the insert plate 503 relative to the guide groove.

[0045] In this way, the two sides of the wedge block 605 abut against the insertion end 504 and the bottom of the groove 604 respectively, forming a mechanical filling and locking, and the wedge block 605 locks the separation state between the fixed section 500 and the movable section 600.

[0046] At this point, the axial pressure on the support structure changes from the hydraulic support state of the jack 201 to the mechanical load state of the wedge block 605. The wedge block 605 itself does not retract over time, thus avoiding the slight hydraulic retraction and prestress loss caused by the long-term load of the jack 201, thereby ensuring the long-term stable maintenance of axial prestress throughout the entire excavation process.

[0047] As an extended embodiment, in construction step 1), two movable annular walls 700 are protruding from the outer periphery of the movable segment 600, and the two movable annular walls 700 are arranged at intervals to form an annular axial elastic interval; an axially movable ring is provided in the axial elastic interval, and the axial movable ring is arranged around the outer periphery of the movable segment 600. The lower part of the axial movable ring is movably embedded in the axial elastic gap to form the axial lower ring 701, and the upper part of the axial movable ring extends to the outside of the axial elastic gap to form the axial upper ring 702. The axial lower ring 701 is provided with axial elastic layers 703 on both sides. The axial elastic layers 703 abut against the movable annular wall 700 and are in an elastic compression state. Two supporting annular walls 800 are protruding on the outer periphery of the supporting steel pipe 300. The two supporting annular walls 800 are arranged at intervals to form an annular radial elastic interval. A radially movable ring is provided in the radial elastic interval, and the radially movable ring is arranged around the circumference of the supporting steel pipe 300. The lower part of the radial movable ring is movably embedded in the radial elastic space to form a radial lower ring 801, and the upper part of the radial movable ring extends out of the radial elastic space to form a radial upper ring 802; two supporting annular walls 800 clamp the radial lower ring 801 facing each other, restricting the axial movement of the radial lower ring 801; a radial elastic layer 803 is provided at the bottom of the radial lower ring 801, and the radial elastic layer 803 presses against the outer periphery of the supporting steel pipe 300 and is in an elastic compression state; In construction step 4), bolt 406 passes through the axial upper ring 702 and is fixedly connected to the axial upper ring 702, thus relieving the axial stress impact of the axial movable ring elastic buffer flange 400; bolt 406 passes through the radial upper ring 802 and is fixedly connected to the radial upper ring 802, thus relieving the radial stress impact of the radial movable ring elastic buffer flange 400.

[0048] When the enclosure structure 100 undergoes instantaneous displacement and the flange 400 is subjected to axial stress impact, the impact force is transmitted along the bolt 406 to the upper axial ring 702, driving the axial movable ring to move slightly within the axial elastic interval. The axial elastic layers 703 on both sides undergo elastic compression deformation, converting the impact energy into elastic deformation energy, so as to prevent the flange 400 from directly bearing the instantaneous stress peak and causing out-of-plane buckling.

[0049] When the enclosure structure 100 undergoes lateral displacement and the flange 400 is subjected to radial stress impact, the impact force is transmitted along the bolt 406 to the radial upper ring 802, driving the radial movable ring to move slightly in the radial direction. The bottom radial elastic layer 803 is further elastically compressed to absorb and convert the radial impact energy, so as to prevent the flange 400 from becoming laterally unstable due to sudden changes in radial load.

[0050] In this way, the two sets of elastic buffer structures can respectively cope with the stress impact in the axial and radial directions, covering the safety protection of flange 400 under complex stress directions; moreover, the elastic buffering effect of the movable ring provides continuous impact protection for the locked support structure, improving the stability and reliability of the support stress.

[0051] As an extended embodiment, in construction step 1), a radial groove 804 is provided in the middle of the radial elastic layer 803. The radial groove 804 is arranged around the circumference of the radial elastic layer 803. The top of the radial groove 804 penetrates the top of the radial elastic layer 803 to form a top opening. The bottom of the radial groove 804 extends to the middle of the radial elastic layer 803 and is arranged in a closed manner.

[0052] When the radial elastic layer 803 is subjected to radial compression, the elastic material will expand to both sides, while the radial groove 804 in the middle provides a release space for the elastic material to deform inward, increasing the compressibility of the radial elastic layer 803 and thus improving the radial elastic deformation capability of the radial elastic layer 803.

[0053] After the connection and fastening are completed in construction step 4, when the radial movable ring is subjected to radial stress impact and undergoes radial displacement, the radial elastic layer 803 with a larger deformation stroke can buffer the impact energy within a larger radial displacement range, making the radial movable ring more adaptable to radial stress impact of different degrees, and ensuring that the stability of the support stress is maintained and does not fail due to accidental impact in the radial direction.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
