Detailed Description
The present invention will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent.
The embodiment of the invention provides a construction platform adaptive to an inclined panel of a concrete stone dam, which comprises hoisting equipment 2 and construction platforms 5 adaptive to different inclined planes, wherein the hoisting equipment 2 is connected with the construction platforms 5 through ropes 4 to control the construction platforms 5 to lift along the inclined plane of the earth-stone dam 1.
The laying process of the panel 16 area is as follows: firstly, paving vertical joint mortar strips; manually leveling, and paving a water stopping frame vertical side mold 3; the side mould 3 is provided with a water stop protection groove; fixing the side mold 3 by using a thick wood plate, a staple and the like; and finally, carrying out single-layer bidirectional reinforcement construction and grouting to realize block pouring. And a deformation slot is reserved in the block pouring process.
As shown in fig. 1-2, the laying of the panel 16 area is performed on the construction platform 5 by an operator, the construction platform 5 is slidably connected to the side mold 3 with the inclination consistent with that of the panel 16, the construction platform 5 comprises a main platform 6, the main platform 6 comprises a bottom plate 61, a supporting rod 62 is fixed on the bottom plate 61, an operation table 63 is hinged to the upper end of the supporting rod 62, an electric push rod 64 is hinged to the bottom of the operation table 63 through a connecting block, the output end of the electric push rod 64 is hinged to the bottom plate 61 through a connecting block, and the operation table 63 is driven by the driving of the electric push rod 64 to change the included angle of the operation table 63 relative to the bottom plate 61 so as to adapt to the steepness degree of the panels 16 of different earth-rock dams 1, so that the operation table 63 is always in a horizontal state.
Both sides and the rear side of the operation table 63 are provided with guardrails 7, which give security to operators.
Further, an auxiliary platform 8 with a smaller size is connected to the underside of the main platform 6, and the auxiliary platform 8 has substantially the same structure as the main platform 6. The auxiliary platforms 8 can be arranged at intervals, so that the operation is convenient to be performed simultaneously in batches, and the construction is more efficient. Wherein the auxiliary platform 8 can be fixedly connected to the lower side of the main platform 6 through a connecting rod 9. Of course, the electric push rod 64 can be movably connected, so that operators positioned on the auxiliary platform 8 can further independently adjust the construction position, and the construction flexibility of the application construction platform 5 is further improved.
Because the electric push rods 64 are required to be provided with a power supply, a matched circuit and the like on the construction platform 5, and the electric push rods 64 are provided with a plurality of electric push rods, the construction period is long, the application cost is higher, and the subsequent maintenance is more complicated, as a further improved example, as shown in fig. 4-9, the use of the electric push rods 64 is canceled through the structural improvement, so that the operation platform 63 is always horizontally adapted to the steep degrees of the panels 16 of different earth-rock dams 1.
Specifically, the construction platform 5 includes a movable frame 10, and in use, the ground of the movable frame 10 engages the face plate 16 of the earth-rockfill dam 1. The movable frame 10 is internally and movably connected with an operation table 63, and the operation table 63 changes an included angle with the bottom surface of the operation table 63 through a mechanical auxiliary displacement structure arranged on the movable frame 10, so that the operation table 63 can be always horizontal when the construction platform 5 is applied to the surfaces of different earth-rock dams 1.
The auxiliary shifting structure comprises a screw rod pivoted on the side edge of the movable frame 10, sliding grooves 15 are respectively formed in the two corresponding sides of the movable frame 10, a first sliding block 13 which is in sliding connection with the sliding grooves 15 is respectively hinged on the two sides of the upper end of the operating platform 63, and the sliding block is in threaded connection with the screw rod. Two sides of the lower end of the operating platform 63 are respectively hinged with a second sliding block 14 which is correspondingly and slidably connected with the side edge of the movable frame 10. The other end of the screw rod penetrates to the outer side of the moving frame 10, and can rotate to drive the inner side first slide block 13 to horizontally move (the screw rod in the horizontal state is set as a first screw rod 11, and the screw rod in the vertical state is set as a second screw rod 12).
Fig. 4-5, 6-7, 8-9 are schematic illustrations of the construction platform 5 at different levels of steepness of the panel 16.
As shown in fig. 4-5, in the state where the steepness of the panel 16 is relatively low, the first slider 13 is screwed on the horizontally arranged screw rod and serves as a limiting end, and the second slider 14 is slidably connected to two side edges of the longitudinal moving frame 10 and abuts against the two side edges (due to the inclined state, the second slider 14 can abut against the supporting console 63 to a certain extent).
As shown in fig. 6-7, in order to make the panel 16 have a state of a certain steepness, the first slider 13 is screwed on the horizontally arranged screw rod and serves as a limiting end, and the second slider 14 is slidably connected to and abutted against two side edges of the bottom horizontal moving frame 10.
As shown in fig. 8-9, in the steeper state of the panel 16, the first slider 13 is screwed on the vertically arranged screw rod and serves as a limiting end, and the second slider 14 is slidably connected to and abuts against two side edges of the bottom horizontal moving frame 10.
In the improvement scheme, the connection position of the first sliding block 13 and the second sliding block 14 at the two ends of the operating platform 63 can be directly selected according to the steepness degree of the panel 16 of the earth-rock dam 1, so that the operating platform 63 can be always horizontal in application.
In the scheme, due to the existence of deformation slots after block pouring in the process of the forced deformation of the panel 16, a deformation space with a proper degree can be utilized, and the forced state of the whole panel 16 is changed, so that the panel 16 is prevented from being cracked or broken rapidly due to the fact that the panel 16 is deformed in a pulling-pressing manner due to uneven settlement and displacement of a rock-fill dam body.
As shown in fig. 3, the deformation slot 17 is embedded with a back-shaped steel groove 18, and the deformation slot is partially filled to play a role of supporting and filling, so that the whole stress of the panel 16 formed by pouring the partition is better. Secondly, the two ends of the steel bar 18 are communicated, and whether the concrete dam is deformed or not can be indirectly monitored by detecting whether the size of the inner side wall of the steel bar 18 is changed or not. That is, the change of the size of the inner side wall of the steel 18 indicates that the panel 16 is deformed under the stress, and the damage condition exists, so that the repair can be performed rapidly.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the invention thereto, but to limit the invention thereto, and any modifications, equivalents, improvements and equivalents thereof may be made without departing from the spirit and principles of the invention.
