Description

Technical Field

[0001] The present invention relates to the technical field of large anchor foundation construction. More specifically, the present invention relates to a matching manufacturing jig and construction method for flange row-inserted steel bars of a super-deep diaphragm wall steel reinforcement cage. Background Art

[0002] In the construction of anchor foundation, the circular foundation pit can exert the arch effect of the diaphragm wall, and the stress is mainly the vertical bending moment. The size of the compartment of the double-loop retaining structure is large and the foundation pit is deep, and the stress is mainly the horizontal bending moment. In the super-deep diaphragm wall anchor foundation of the large new double-loop retaining structure, the traditional joints do not meet the stress requirements, and a new type of socket rigid joint needs to be adopted. The new type of socket rigid joint and the socket steel reinforcement cage are matched and lapped to jointly form the rigid skeleton of the diaphragm wall, and a complete diaphragm wall is formed after pouring the late-stage concrete.

[0003] During the construction process, first, the socket rigid joint needs to be installed, and then the socket steel reinforcement cage is installed after the socket rigid joint is installed in place. When the socket rigid joint is installed, it is affected by structural deformation and sectional docking deviation, and there are certain deviations in its line type and verticality, which leads to deviations in the installation space of the socket steel reinforcement cage in the later stage, and interference occurs at the lapping part between the socket rigid joint and the steel reinforcement cage flange. In order to ensure the smooth lowering and installation of the socket steel reinforcement cage and avoid the phenomenon of "cage jamming", it is necessary to carry out matching manufacturing of the socket steel reinforcement cage.

[0046] In addition, the embodiments of the present invention involved in the following descriptions are usually only part of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] The following further describes the present invention in detail with reference to the accompanying drawings and embodiments, and the specific implementation process is as follows:

[0048] As Figures 1 to 9As shown in the figure, the present invention provides a matching manufacturing jig for the wing flange inserted steel bars of a super-deep diaphragm wall steel reinforcement cage, which includes n modular units symmetrically arranged on both sides of the steel reinforcement cage; a single modular unit includes a walking drive mechanism 1, a walking chassis 2, a lifting drive mechanism 3, a movable steel bar bracket 4, and an inserted steel bar caliper 5; the inserted steel bar caliper 5 is used to limit the lateral position of the outer end of the wing flange inserted steel bar, and the end face of the caliper is used to limit the end of the steel bar, so that the linear type of the outer end of the wing flange inserted steel bar of the steel reinforcement cage can be well controlled.

[0049] The walking chassis 2 is movably arranged on the walking drive mechanism 1, the lifting drive mechanism 3 is arranged on the walking chassis 2 and is used to lift the movable steel bar bracket 4, and the inserted steel bar caliper 5 is arranged on the movable steel bar bracket 4;

[0050] The movable steel bar bracket 4 is used for the precise positioning and linear type control of the wing flange inserted steel bars of the super-deep diaphragm wall steel reinforcement cage. The movable steel bar bracket 4 includes: a cantilever lower bracket 41, a distributed rotary vertical rod 42, a step-adjustable upper bracket 43, a positioning pin 44, and a diagonal brace 45;

[0051] The cantilever lower bracket 41 is a Z-shaped cantilever structure. Driven by the lifting drive mechanism 3, it carries the distributed rotary vertical rod 42 and the step-adjustable upper bracket 43 to move in the vertical direction. A longitudinal positioning rack 4c is arranged on the cantilever lower bracket 41, and the longitudinal positioning rack 4c is parallel to the length direction of the steel reinforcement cage, which can precisely position the longitudinal spacing of the lower-layer wing flange inserted steel bars 7 of the steel reinforcement cage; the lower end of the distributed rotary vertical rod 42 is hinged to the cantilever lower bracket 41 through the positioning pin 44, and the attitude change from the horizontal state to the vertical state can be realized; the end of the step-adjustable upper bracket 43 is hinged to the step-adjustable positioning hole 4d arranged on the distributed rotary vertical rod 42 through the positioning pin 44. The step-adjustable positioning hole 4d includes a seat body arranged on the distributed rotary vertical rod 42 and multiple rows of positioning holes arranged in the height direction of the seat body. The step adjustment is realized through the connection of positioning holes at different heights. A transverse positioning rack 4f is arranged on the top surface of the step-adjustable upper bracket 43, and the transverse positioning rack 4f is used for the transverse positioning of the upper-layer wing flange inserted steel bars 8 of the steel reinforcement cage; a diagonal brace chute 4e is arranged on the bottom surface of the step-adjustable upper bracket 43, and a diagonal brace 45 is arranged between the diagonal brace chute 4e of the step-adjustable upper bracket 43 and the distributed rotary vertical rod 42, and between the distributed rotary vertical rod 42 and the cantilever lower bracket 41. The step adjustment of the spacing between the upper and lower layer wing flange inserted steel bars is completed through the cooperation of the step-adjustable positioning hole 4d, the diagonal brace chute 4e, and the diagonal brace 45. During the matching manufacturing process, under the action of the diagonal brace 45, the distributed rotary vertical rod 42 is perpendicular to the top surface of the cantilever lower bracket 41, and the step-adjustable upper bracket 43 is perpendicular to the distributed rotary vertical rod 42, so that the planes where the upper and lower layer wing flange inserted steel bars are located are parallel.

[0052] In the above technical solution, the matching manufacturing jig for the flange inserted steel bars of the ultra-deep diaphragm wall steel reinforcement cage consists of n modular units. The value of n is determined according to the length of the steel reinforcement cage. The distance between the upper and lower brackets is adjusted according to the matching manufacturing data, and then the n modular units are synchronously moved horizontally and lifted vertically to the specified position to complete the matching manufacturing of the flange inserted steel bars of the ultra-deep diaphragm wall steel reinforcement cage.

[0053] The matching manufacturing jig for the flange inserted steel bars of the ultra-deep diaphragm wall steel reinforcement cage in this application: 1) Adopts a lead screw motor drive. Utilizing the characteristics of stable transmission ratio, good transmission continuity, and self-locking of the lead screw drive, it realizes the rapid movement and precise positioning of the flange inserted steel bar jig in the horizontal direction; 2) Adopts a vertical guiding mechanism in cooperation with a screw jacking mechanism. The guiding mechanism offsets the overturning moment generated by the cantilever bracket, and the screw jacking mechanism provides a stable vertical thrust to realize the rapid lifting and precise positioning of the flange inserted steel bar jig in the vertical direction; 3) Adopts a cantilever lower bracket 41, a distributed rotary vertical rod 42, and a step-adjustable upper bracket 43 to realize the step adjustment of the distance between the upper and lower steel bars brackets. At the same time, it can provide a steel bar splicing working platform for the main cage steel bar binding, reducing the occupation of the steel reinforcement cage manufacturing site; 4) Adopts a modular design and continuous layout, which is convenient for installation and disassembly. The number of flange inserted steel bar matching manufacturing jig modules is selected according to the length of the steel reinforcement cage to be manufactured, which can meet the matching manufacturing of diaphragm wall steel reinforcement cages with different lengths and the linear control of the flange inserted steel bars; 5) The matching manufacturing jig and construction method for the flange inserted steel bars of the ultra-deep diaphragm wall steel reinforcement cage solve the problems of rapid adjustment and precise positioning of the flange inserted steel bar jig during the matching manufacturing process of the steel reinforcement cage, and provide a solution for the high-precision linear control of the flange steel mesh of the ultra-deep diaphragm wall steel reinforcement cage.

The traveling chassis 2 includes: a chassis keel 21, a guide rail wheel set 22, and the traveling lead screw flange 2b is arranged on the chassis keel 21;

The lifting drive mechanism 3 includes: a lifting guide rod 31, a lifting screw assembly 32, and a lifting drive motor 33;

[0058] The lifting guide rods 31 are symmetrically installed on the top surface of the chassis keel 21 and cooperate with the linear bearings 4b provided on the cantilever lower bracket 41 to stably lift the movable steel bar bracket 4 in the vertical direction; the lifting screw assembly 32 is docked with the lifting screw flange 4a provided on the cantilever lower bracket; the lifting drive motor 33 is installed on the lifting drive motor 33 supports 2a provided on both sides of the chassis keel 21. When operating, the torque is transmitted to the lifting screw assembly 32, and the lifting screw assembly 32 converts the torque into thrust to drive the movable steel bar bracket 4 to act.
