The pads can provide support points for the arches and reduce the phenomenon of arch feet hanging in the air. Therefore, a large number of arch foot pads are needed during the construction process. In the prior art, when the arch foot pads are cast, the molds are prone to displacement due to the lack of reliable limit, and the arch foot pads are difficult to form. The casting and tamping of the arch foot pads require multiple people to complete the production at the same time, which is labor-intensive and affects the construction progress. In addition, the quality of the produced arch foot pads is uneven, and virtual slag of the arch foot occurs, which affects the stability of the arch. Therefore, it is necessary to improve the existing casting and tamping method. Summary of the invention

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] An arch foot pad integrated casting and vibrating table, such as Figure 1 and Figure 2 As shown, it comprises a base frame 1 and a tamping table 2, wherein the base frame comprises a frame body 3, and a plurality of legs 4 are symmetrically arranged at the lower end of the frame body, and the tamping table comprises a panel 5, and a template grid 6 is arranged on the upper side of the panel, and a reinforcement frame 7 is arranged on the periphery of the panel ， The template grid is provided with a ring frame 8 ， An array of elastic support mechanisms 9 is provided between the frame and the panel, and an attached vibrator 10 is installed on the lower surface of the panel. In an optional embodiment, the outer periphery of the template grid is detachably mounted on the panel through an outer ring frame, and the thickness of the arch foot pad can be adjusted by adjusting the height of the template grid, which is very convenient and efficient.

[0025] The pouring and vibrating table is not only simple to make and easy to operate, but also reduces the number of people required for each pouring by 1-2 compared to the traditional formwork support, thereby reducing labor costs. The pouring table can be used to centrally produce pads, which is beautiful overall and more convenient for concrete maintenance and transportation. Before pouring, the pouring table is calibrated and the horizontal position is adjusted to ensure that the specifications and dimensions of the pads meet the requirements. During construction, a site is first selected, and the integrated pouring and vibrating table provided by the invention is placed on the ground of the site. Concrete is manually added to the formwork grid, and then the vibrator switch is turned on for vibration. The vibration is stopped by observing the state of the concrete. After the concrete is vibrated into shape, the pads are moved to the pad maintenance platform for maintenance.

[0026] In an optional embodiment, if Figure 3As shown, the elastic support mechanism includes an upper sleeve 14 and a lower sleeve 15. The upper end of the upper sleeve is fixed to the lower surface of the panel, and the lower end of the lower sleeve is fixed to the frame. The upper sleeve is sleeved on the outer wall of the lower sleeve, and the spring is in the lower sleeve. There is a gap of 3-5mm between the outer wall of the lower sleeve and the inner wall of the upper sleeve. The upper sleeve is 5-20mm longer than the lower sleeve, allowing the upper and lower sleeves to extend and retract in the vertical direction. When the vibrator is working, the panel is allowed to float on the frame without excessive shaking, and the stability is good. Two handles 16 are symmetrically arranged on the reinforcing frame. In a further improved solution, the upper end of the spring is fixed to the bottom of the panel, and the lower end of the spring is not connected to the frame. The spring is directly inserted into the lower sleeve, and the lower end of the spring is against the frame. Such a structural design improves the convenience of operation and facilitates the separation of the tamping platform from the frame.

[0027] A reinforcement frame is provided under the panel, and an attached vibrator is installed on the reinforcement frame. The reinforcement frame is H-shaped as a whole, and includes two horizontal frames 12 arranged in parallel. Both ends of each horizontal frame are respectively fixed to the reinforcement frame, and a mounting frame is provided between the two horizontal frames. The attached vibrator is installed on the mounting frame 13. The horizontal frame is welded and fixed to the panel, and both ends of the mounting frame are respectively welded and fixed to the corresponding horizontal frame. The horizontal frame and the mounting frame are both made of angle steel. A group of elastic support mechanisms are respectively provided at the four corners of the panel. The elastic support mechanism includes a spring. A leg is respectively provided at the four corners of the frame. The legs are made of angle steel.

[0028] The invention arranges template grids on the panel, so that arch foot pads can be mass-produced with stable quality control. The structure shape will not change due to mold movement during casting, so the number of pads in the tunnel is guaranteed, the number of construction personnel is reduced, and work efficiency is improved, achieving the purpose of simplicity, convenience, easy operation, rapid construction, and quality improvement, and effectively solving the problems of tunnel arch foot slag and difficulty in forming arch frame pads.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
