[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1-8 The utility model provides a construction platform for bored piles, including a platform top panel 1 and two groups of symmetrically distributed semicircular manhole covers 5. A circular opening 11 is opened through the center of the surface of the platform top panel 1. The outer side of the platform top panel 1 is fixedly connected to an outer square steel plate frame 2. The left and right side walls of the outer square steel plate frame 2 are penetrated by a movable groove 21. The left and right sides of the outer square steel plate frame 2 and one side of the movable groove 21 are fixedly connected with a fixed seat 22. The inner side of the lower end of the outer square steel plate frame 2 and below the platform top panel 1 is fixedly connected to a platform bottom panel 3. A circular opening 231 is opened through the center of the surface of the platform bottom panel 3. The inner sides of the circular opening 11 and the circular opening 231 are jointly fixedly connected with an annular reinforcement plate 4. The two groups of semicircular manhole covers 5 are hinged to the platform The top panels 1 are rotatably connected, and the tops of the two groups of semicircular manhole covers 5 are connected with a driving member 1 for driving the semicircular manhole covers 5 to open. A rectangular notch 51 is provided on the surface of the semicircular manhole cover 5, and a movable plate 6 is slidably connected inside the rectangular notch 51. A semicircular notch 61 for fixing the guide tube 62 is provided on the upper surface of the movable plate 6. The four corners of the surface of the platform top panel 1 are movably connected with the anchor fixing rod 7. A casing 8 is placed on the inner side of the annular reinforcement plate 4 and 5cm-10cm below the semicircular manhole cover 5. Two groups of supporting square steels 9 for supporting the steel cage are slidably connected inside the movable groove 1 21. The left and right side walls of the annular reinforcement plate 4 are penetrated by a movable groove 2 41 that provides a sliding position for the supporting square steel 9. The fixed seat 22 is internally connected with a driving member 2 10 for driving the supporting square steel 9 to move.

[0029] The present invention can provide effective safety protection for construction by arranging a construction platform composed of a platform top panel 1, an outer square steel plate frame 2, a platform bottom panel 3 and an annular reinforcement plate 4 above the casing 8. Two sets of opening and closing semicircular manhole covers 5 are arranged on the inner side of the platform top panel 1. During the drilling and soil excavation process, the semicircular manhole covers 5 can be opened or closed according to the construction situation, so that the hole opening can be sealed to a large extent during the construction process, significantly reducing safety hazards. By arranging the supporting square steel 9, the position of the steel cage can be supported and fixed. By arranging the movable plate 6, the conduit 62 can be supported and fixed during the pouring process, thereby ensuring the stability of the conduit 62 during the pouring process.

[0030] Specific usage:

[0031] 1. After the bored pile casing 8 is buried, the construction platform is positioned and installed with the center of the casing 8 (i.e. the center of the pile position). It is necessary to ensure that the height of the semicircular manhole cover 5 after installation should be 5cm-10cm higher than the top surface of the casing 8. Then, the anchor fixing rod 7 is rammed into the ground to fix the position of the construction platform to ensure that the construction platform will not move during the operation.

[0032] 2. When the drilling rig is in place and ready to start drilling, the semicircular manhole cover 5 is opened by driving member 1, and the drill bit enters the hole (inside the annular reinforcement plate 4). After drilling to a certain depth, the movable plate 6 is pushed into the slot 52 and the semicircular manhole cover 5 is closed at the same time, thereby achieving the effect of sealing the hole. At this time, the shaft of the drill bit is located inside the two sets of rectangular notches 51.

[0033] 3. When the drill bit produces slag, open the semicircular manhole cover 5 again, and repeat steps 2 and 3 during the subsequent drilling process.

[0034] 4. Once drilling is complete, open the semicircular manhole cover 5 and lower the rebar cage. Use the annular reinforcement plate 4 to calibrate the cage's alignment with the pile center (this can be determined by measuring the distance from the cage's perimeter to the annular reinforcement plate 4 at multiple points). While the hoist lowers the cage, drive unit 2 (10) deploys the supporting square steel bars 9 for temporary support. Once the cage is fully lowered and installed, the supporting square steel bars 9 can be used to secure the cage's suspension bars.

[0035] 5. When lowering the perfusion catheter 62, the semicircular manhole cover 5 should be closed and the movable plate 6 should be opened at the same time to facilitate the installation and fixation of the catheter 62.

[0036] Furthermore, a plurality of sets of horse stool bars 32 are fixedly connected between the platform top panel 1 and the platform bottom panel 3 .

[0037] Specifically, the saddle bars 32 are fixedly connected between the platform top panel 1 and the platform bottom panel 3, which can enhance the stability and load-bearing capacity of the structure and ensure that the construction platform will not deform or become unstable during construction. The arrangement of the saddle bars 32 can be reasonably configured according to the actual use and design requirements of the construction platform. Preferably, multiple groups of saddle bars 32 will be evenly distributed between the platform top panel 1 and the platform bottom panel 3 to ensure uniform support of all parts of the construction platform.

[0038] Furthermore, an annular placement groove 42 for placing the semicircular manhole cover 5 is opened at the inner upper end of the annular reinforcement plate 4.

[0039] Specifically, the annular placement groove 42 can provide a placement position for the semicircular manhole cover 5 after being buckled, so that the position of the semicircular manhole cover 5 after being buckled is more stable.

[0040] Furthermore, the platform top panel 1 and the semicircular manhole cover 5 are both made of steel grating plates.

[0041] Specifically, steel gratings have good load-bearing capacity and durability. At the same time, compared to solid steel plates, steel gratings are lighter, which helps reduce the weight of the overall structure and facilitates installation and maintenance.

[0042] Furthermore, a slot 52 is provided on one side of the rectangular notch 51 , and the movable plate 6 is slidably connected to the inside of the slot 52 . A fixing bolt 521 for fixing the movable plate 6 is threadedly connected to the semicircular manhole cover 5 .

[0043] Specifically, when the movable plate 6 is needed to secure the conduit 62, the movable plate 6 is removed from the slot 52 and tightened using the fixing bolt 521 to ensure that the movable plate 6 does not move while securing the conduit 62, thereby providing stable support. An annular protrusion 621 is provided on the outside of the conduit 62. The outer diameter of the annular protrusion 621 is larger than the diameter of the two sets of semicircular notches 61. When the two sets of movable plates 6 are moved out and brought together, the conduit 62 is placed inside the two sets of semicircular notches 61. Since the outer diameter of the annular protrusion 621 of the conduit 62 is larger than the diameter of the semicircular notches 61, the semicircular notches 61 restrict the position of the annular protrusion 621, thereby ensuring that the conduit 62 is stably fixed in place.

[0044] Furthermore, the driving member 1 is a hydraulic rod 53, the telescopic end of the hydraulic rod 53 is rotatably connected to a connecting seat 1 54, and the connecting seat 1 54 is fixedly connected to the upper surface of the semicircular manhole cover 5, and the end of the hydraulic rod 53 away from the telescopic end is rotatably connected to a connecting seat 2 55, and the front and rear sides of the outer square steel plate frame 2 are fixedly connected to a T-shaped plate 56, and the connecting seat 2 55 is fixed to the T-shaped plate 56.

[0045] Specifically, the purpose of flipping the semicircular manhole cover 5 can be achieved by driving the hydraulic rod 53 to extend and retract, thereby realizing the opening and closing of the semicircular manhole cover 5.

[0046] Furthermore, one side of the supporting square steel 9 is rotatably connected to a pulley 91, and the outer side of the pulley 91 is slidably connected to a slide rail 92, which is fixedly connected to the front and rear sides of the inner side of the movable groove 21.

[0047] Specifically, when the supporting square steel 9 moves, it drives the pulley 91 on one side to slide in the slide rail 92. The use of the pulley 91 reduces the direct contact friction between the supporting square steel 9 and the inner surface of the movable groove 21, thereby making the movement of the supporting square steel 9 smoother.

[0048] Furthermore, the driving component 2 10 includes a wide rack 101, a reduction motor 102 and a gear 103. The wide rack 101 is fixedly connected to the inner side of two groups of supporting square steels 9 located on the same side. The reduction motor 102 is fixedly connected to the inside of the fixed seat 22. The output shaft of the reduction motor 102 is fixedly connected to the gear 103, and the gear 103 is meshed with the wide rack 101.

[0049] Specifically, when the steel cage is lowered, the steel cage can be supported by the supporting square steel 9. Specific operation method: Control the reduction motor 102 to operate, and the reduction motor 102 drives the gear 103 to rotate through the output shaft, thereby driving the wide rack 101 meshing with the gear 103 to move, and the wide rack 101 drives the supporting square steel 9 to slide within the two sets of slide rails 92.

[0050] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
