The deep foundation pit concrete internal support removal construction technology refers to the construction technology of removing the concrete internal support structure after the deep foundation pit support transformation or construction project is completed. With the continuous development of urban construction in my country, the application of deep foundation pit concrete internal support removal construction technology has become more and more extensive. Usually, in the process of removing the reinforced concrete internal support beams in deep foundation pits, construction units will take supporting components at the bottom of the removed beams to prevent the removed beams from falling and injuring people, or local beam collapse during the removal of reinforced concrete internal support beams. Generally, steel pipes are used to set up full-height scaffolding to ensure construction safety, which can achieve the effect of safe construction.

When moving the device, the handle 19 is held by hand, and the rubber pad 20 can increase the friction between the handle 19 and the hand, making it convenient to apply force.

[0026] A hydraulic rod 3 is fixedly connected to the upper surface of the support plate 2, and a contact plate 4 is fixedly connected to the top of the hydraulic rod 3. A concrete body 5 is arranged on the upper surface of the contact plate 4. A motor 6 is fixedly connected to the bottom surface of the support plate 2. There are four hydraulic rods 3, which are symmetrically distributed on the bottom surface of the contact plate 4. The hydraulic rods 3 can prevent the contact plate 4 from tilting when the concrete body 5 is pressed on the contact plate 4, so that the force is more evenly distributed.

[0027] The output shaft end of the motor 6 is fixedly connected with a threaded rod 7, and the threaded rod 7 rotates and penetrates the bottom surface of the support plate 2. The motor 6 provides power for the threaded rod 7, which is convenient for operation. The outer surface of the threaded rod 7 is threadedly connected with a moving plate 8. The motor 6 is started, and the motor 6 drives the threaded rod 7 to rotate, so that the moving plate 8 moves up, and the moving plate 8 moves up with the contact plate 4. The outer surface of the contact plate 4 is provided with a groove 10, and the inner wall of the groove 10 is slidably connected with a U-shaped plate 11. The bottom surface of the U-shaped plate 11 is fixedly connected to the upper surface of the support plate 2.
