The sliding rod continues to slide down and gradually moves away from the insertion cone. At this time, the drill bit at the bottom of the sliding rod can be deeply inserted into the soil layer.

The plurality of X-shaped frames cooperate with each other to firmly fix the two arm plates together and form an upper and lower double-layer support structure. The opposite sides of the two arm plates are provided with criss-cross-shaped reinforcing ribs. The structural strength of the arm plates is improved by the reinforcing ribs. The upper and lower double-layer support structure and the reinforcing ribs are used in combination to improve the support strength and support stability of the anti-settlement mechanism. Furthermore, the cross beam extends outward from the arm plate. During landfill, the cross beam is also completely buried underground. After being buried, the overall contact area between the anti-settlement mechanism and the underground soil layer can be increased.

DETAILED DESCRIPTION

[0027] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component may be enlarged or reduced. The embodiments listed in the present invention are only used to illustrate the present invention and are not used to limit the scope of the present invention. Any obvious modifications or changes made to the present invention do not depart from the spirit and scope of the present invention.

[0028] See also Figures 1 to 6 In an embodiment of the present invention, a shield machine tunnel stratum anti-subsidence construction device includes a supporting mechanism 1 and an anti-subsidence mechanism 2. The supporting mechanism 1 is welded and fixed to the anti-subsidence mechanism 2, and the upper end component of the supporting mechanism 1 is located above the anti-subsidence mechanism 2. During construction, the anti-subsidence mechanism 2 and the lower end components of the supporting mechanism 1 are buried underground. After burying, the upper end component of the supporting mechanism 1 is exposed to the ground and flush with the ground. The supporting mechanism 1 is used to support other construction structures on the ground, and the anti-subsidence mechanism 2 is used to support the supporting mechanism 1 and prevent the supporting mechanism 1 from sinking downward.

[0029] See also Figure 3 , Figure 4 , Figure 5The anti-settling mechanism 2 includes two arm plates 22 arranged opposite to each other in an upper and lower direction. The two arm plates 22 are buried underground during construction. A plurality of X-shaped frames 25 are welded between the two arm plates 22. The plurality of X-shaped frames 25 cooperate with each other to firmly fix the two arm plates 22 together and form an upper and lower double-layer support structure.

[0030] A reserved hole 24 is provided at the center of the inner wall of the two arm plates 22. The centers of the two reserved holes 24 are aligned and matched with each other for installing the supporting mechanism 1. A plurality of lower connecting angle plates 21 are provided at the bottom of the lower one of the two arm plates 22.

[0031] The two arm plates 22 are provided with a tic-tac-toe reinforcing rib 26 on the opposite side. The structural strength of the arm plates 22 is improved by the reinforcing rib 26. The upper and lower double-layer support structure and the reinforcing rib 26 are used together to improve the support strength and support stability of the anti-sinking mechanism 2.

[0032] A plurality of cross beams 23 are fixed at equal intervals at the front and rear ends of the two arm plates 22. The plurality of cross beams 23 cooperate with each other to increase the contact area between the anti-settling mechanism 2 and the underground soil layer and thereby enhance the supporting stability of the anti-settling mechanism 2 on the supporting mechanism 1;

[0033] In this embodiment, the cross beam 23 extends outward from the arm plate 22. During landfill, the cross beam 23 is also completely buried underground. After being buried, the overall contact area between the anti-subsidence mechanism 2 and the underground soil layer can be increased. The larger the contact area, the greater the support strength of the underground soil layer for the anti-subsidence mechanism 2. The anti-subsidence mechanism 2 can more stably support the supporting mechanism 1, thereby effectively preventing the supporting mechanism 1 from sinking downward.

The probe column 16 is integrally formed at the center of the bottom of the support plate 11, and a plurality of upper connecting angle plates 15 are fixed around the probe column 16 and the support plate 11 at equal intervals. The plurality of upper connecting angle plates 15 cooperate with each other and are used to strengthen the connection between the support plate 1 and the probe column 16 and provide effective support for other surfaces of the support plate 11 away from its own center.

A plurality of lower connecting angle plates 21 are fixed around and around the probe column 16 and the lower arm plate 22 at equal intervals. The plurality of lower connecting angle plates 21 cooperate with each other to strengthen the connection between the probe column 16 and the arm plate 22 to prevent it from falling off from the reserved hole 24.

[0036] The bottom end of the probe column 16 is integrally formed with a probe cone 17, which is a conical table structure with a circular cross section at the bottom end. The drill bit 14 is slidably arranged at the bottom of the probe cone 17. The insides of the probe column 16 and the probe cone 17 are respectively provided with a first cavity 18 and a second cavity 113, which are not connected to each other, and a slider 19 and a slide plate 111 are slidably connected to the first cavity 18 and the second cavity 113 respectively.

[0037] A plurality of guide rods 110 are fixed between the slider 19 and the slide plate 111. Guide holes 114 are provided on one side of the inner wall of the probe column 16 and the probe cone 17 corresponding to the plurality of guide rods 110. The plurality of guide rods 110 are respectively slidably connected in the guide holes 114 on the corresponding side. A linkage structure is formed between the slider 19 and the slide plate 111 through the coordinated use of the guide rods 110 and the guide holes 114. When the slider 19 slides up and down, it drives the slide plate 111 to move synchronously. A slide rod 112 is fixed at the center of the bottom of the slide plate 111. One end of the slide rod 112 slides through the inner wall of the probe cone 17 and extends to the bottom of the probe cone 17. The bottom end of the slide rod 112 is connected and fixed to the drill bit 14.

[0038] A screw 13 is rotatably connected in the middle position inside the first cavity 18. The screw 13 thread penetrates the slider 19 and extends to one side of the support plate 11. A hole groove is provided on the inner wall of the support plate 11 corresponding to one side of the screw 13. The screw 13 is rotatably connected in the hole groove, and the top of the screw 13 is flush with the upper surface of the support plate 11. A cross cutter is provided on the top of the screw 13.

[0039] In this embodiment, during construction, the supporting mechanism 1 and the anti-settling mechanism 2 are buried in a pre-dug pit and filled with soil. After burying, the support plate 11 of the supporting mechanism 1 is located on the ground surface and flush with the ground. At this time, the screw 13 is rotated by an electric screwdriver, and the screw 13 is threadedly matched with the slider 19. As the screw 13 continues to rotate, the slider 19 will continue to move downward along the first cavity 18. When the slider 19 moves downward, it will drive the slide plate 111 to move synchronously. The slide plate 111 slides downward in the second cavity 113, and will drive the sliding rod 112 connected to it to slide down synchronously. The sliding rod 112 continues to slide down and gradually moves away from the probe cone 17. At this time, the drill bit 14 at the bottom end of the slide rod 112 can be deeply inserted into the soil layer. The deeper the drill bit 14 is inserted, the better the positioning and fixing effect between the probe column 16, the probe cone 17 and the underground soil layer.
