[0042] It should be noted that the base is suitable for multi-storey buildings of wood or steel structure.

[0043] In the embodiment, the inner cavity of the descending drill cylinder 22 is pre-filled with water, then the mounting base 1 is moved to the designated position, the support column 51 is inserted into the ground through the center of the mounting base 1, then the threaded rod 53 is screwed into the inner cavity of the mounting base 1 through the support plate one 31 and is inserted into the inner cavity of the limiting hole 52 to fix the position of the support column 51, after the position of the support column 51 is fixed, the threaded hole is tapped on the surface of the support column 51, and then the movable seat 39 is screwed through the threaded hole on the surface of the support column 51;

[0044] Then the sliding baffle 23 is pulled out, at this time the strong spring 21 loses the limiting of the sliding baffle 23, and releases a strong pushing force to drive the descending drill cylinder 22 to insert into the ground, if the ground is soft, the descending drill cylinder 22 can directly insert into the ground, then drives the descending rod 25 to descend, when the descending rod 25 descends and contacts with the locking rod 27, thereby driving the locking rod 27 to descend, the locking rod 27 is pulled out from the inner cavity of the sleeve ring 28, and then the support plate one 31 and the support plate two 32 lose the limiting of the locking rod 27, and are rotated and laid on the ground, and are self-locked and fixed through the support telescopic rod 36, so that the support plate one 31 and the support plate two 32 contact with the ground, thereby realizing that when the mounting base 1 and the support column 51 are installed on the ground, the support plate one 31 and the support plate two 32 can be laid on the ground after the descending drill cylinder 22 judges that the ground is soft, thereby increasing the contact area with the ground through the support plate one 31 and the support plate two 32, so that the mounting base 1, the support plate one 31 and the support plate two 32 can bear force uniformly, thereby slowing down the settlement speed of the mounting base 1 and the support column 51 on the soft ground;

[0045] And the building and installation base 1 will form overhead layer, these overhead layer because the hard ground can be used by people, overhead layer utilization is higher, and in the hard ground, the settlement speed of installation base 1 and support mechanism 5 is extremely slow, therefore, do not use support plate one 31 and support plate two 32, avoid occupying larger ground influence people walk, and in the soft ground, the area cannot be used, so that the use of support plate one 31 and support plate two 32 on the soft ground laid also will not affect the use of the area;

[0046] When the support plate one 31 and support plate two 32 are laid on the ground, the support telescopic rod 36 is pulled out from the inner cavity of the telescopic sleeve rod 34 through the fixing seat 35, so that the total length of the telescopic sleeve rod 34 and the support telescopic rod 36 is elongated, and the telescopic sleeve rod 34 and the support telescopic rod 36 can only be elongated through the clamping of the ratchet bar 37 and the pawl 38, if the telescopic sleeve rod 34 and the support telescopic rod 36 are to be retracted, the coil spring 33 is already contracted to the minimum state, the pawl 38 can only swing upward of the telescopic sleeve rod 34 with the coil spring 33 as the axis, and cannot swing toward the direction of the ratchet bar 37 with the coil spring 33 as the axis, so that the telescopic sleeve rod 34 and the support telescopic rod 36 cannot be retracted;

[0047] When the settlement occurs in a certain position, the jack is placed between the corresponding support ring 54 and the installation base 1, then the threaded rod 53 is pulled out from the inner cavity of the limiting hole 52, then the support column 51 is jacked up through the jack, so that the distance between the support ring 54 and the installation base 1 is increased, so that the support ring 54 is increased relative to the installation base 1, at this time, the high place of the support column 51 is assisted and supported through the self-locking of the support telescopic rod 36 and the telescopic sleeve rod 34, so that the situation that the support column 51 is not stable after the settlement and the support column 51 is increased relative to the installation base 1 is avoided;

[0048] When the position of the support column 51 is adjusted, the threaded rod 53 is screwed into the inner cavity of the installation base 1 and inserted into the inner cavity of the limiting hole 52, so that the support column 51 can be limited and locked.

[0049] As Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the embodiment of the present application provides an overhead building base suitable for multi-storey buildings, the knocking mechanism 4 comprises a clamping ring 41 fixedly connected to the top of the guide rod 24, the inner cavity of the clamping ring 41 clamps a knocking plate 42, the bottom of the knocking plate 42 is provided with a clamping groove 43, the knocking plate 42 is clamped with the clamping ring 41 through the clamping groove 43, the bottom end of the knocking plate 42 is fixedly connected with a water baffle rod 44, the bottom end of the descending drill cylinder 22 is fixedly connected with a water inlet cylinder 45, the bottom end of the water baffle rod 44 is attached to the top of the inner cavity of the water inlet cylinder 45, the bottom end of the water inlet cylinder 45 is fixedly connected with a water outlet pipe 46, and the bottom of the water outlet pipe 46 is fixedly connected with a one-way water outlet valve 47.

[0050] The top of the water baffle rod 44 located in the inner cavity of the descending drill cylinder 22 is fixedly connected with a limiting plate 48, the top end of the inner cavity of the descending drill cylinder 22 is fixedly connected with a rectangular plate 491, the side of the rectangular plate 491 away from the limiting plate 48 is fixedly connected with a tension spring 49, one end of the descending rod 25 located in the inner cavity of the descending drill cylinder 22 is fixedly connected with the tension spring 49, and the end of the descending rod 25 away from the locking rod 27 penetrates through the rectangular plate 491 and is attached to the limiting plate 48.

[0051] In this embodiment, after the sliding baffle 23 is pulled out from below the descending drill cylinder 22, if the ground is hard, the pushing force of the strong spring 21 cannot insert the descending drill cylinder 22 into the ground, then the knocking plate 42 is hammered by external equipment or manually, so that the clamping ring 41 and the clamping groove 43 are separated, and the knocked knocking plate 42 is lowered;

[0052] After the knocking plate 42 is lowered, the water baffle rod 44 is lowered, the water baffle rod 44 drives the limiting plate 48 to be lowered and separated from the descending rod 25, at this time, the pushing force of the tension spring 49 drives the descending rod 25 to move towards the rectangular plate 491, so that the descending rod 25 is pushed into the inner cavity of the descending drill cylinder 22;

[0053] And the water baffle rod 44 is lowered in the inner cavity of the water inlet cylinder 45, at this time, the inner cavities of the descending drill cylinder 22 and the water inlet cylinder 45 are through, the water in the inner cavity of the descending drill cylinder 22 enters the water outlet pipe 46 from the water inlet cylinder 45, and flows out from the water outlet pipe 46 to the ground through the one-way water outlet valve 47, and the one-way water outlet valve 47 prevents soil from entering the upper part of the inner part of the water outlet pipe 46, causing blockage;

[0054] After the ground is softened, the descending drill cylinder 22 is hammered into the ground, so that when hard ground is encountered, the ground is moistened by water, the hard ground is soft, and the descending drill cylinder 22 is easy to enter the ground, then the descending drill cylinder 22 is used to assist in fixing the installation base 1, and then the staff stably installs the installation base 1 and the ground.

[0055] Working principle: firstly, fill the inner cavity of the descending drill cylinder 22 with water, so that the clamping ring 41 is clamped in the inner cavity of the clamping groove 43, move the installation base 1 to the designated position, then install the support column 51 through the installation base 1 to the ground, and lock and stop the support column 51 by screwing the threaded rod 53 through the limiting hole 52, and connect the movable seat 39 with the support column 51, then pull out the sliding baffle 23, when the sliding baffle 23 is separated from the bottom of the descending drill cylinder 22, the strong spring 21 is released to drive the descending drill cylinder 22 to penetrate into the ground, if the ground is soft, the descending drill cylinder 22 descends and penetrates into the ground, when the descending drill cylinder 22 descends, the descending rod 25 contacts with the locking rod 27, and the locking rod 27 is pressed downward, driving the locking rod 27 to move away from the inner cavity of the sleeve ring 28, at this time, the support plate one 31 and the support plate two 32 lose the limitation of the locking rod 27, and fall down by their own gravity, so that the side of the support plate one 31 and the support plate two 32 away from the installation base 1 contacts with the ground;

[0056] When the support plate one 31 and the support plate two 32 fall down, the total length of the telescopic sleeve rod 34 and the support telescopic rod 36 is elongated, and the clamping of the ratchet bar 37 and the pawl 38 makes the support telescopic rod 36 and the telescopic sleeve rod 34 unable to shorten after elongation, thereby limiting and locking the support plate one 31 and the support plate two 32;

[0057] If the ground is hard, the strong spring 21 cannot penetrate into the ground after losing the limitation of the sliding baffle 23, then the knocking plate 42 is hammered by external hammering, the knocking plate 42 moves downward and drives the clamping ring 41 and the clamping groove 43 to separate, then the knocking plate 42 descends and drives the water blocking rod 44 to descend in the inner cavity of the water inlet cylinder 45, so that the inner cavity of the descending drill cylinder 22 is connected with the water inlet cylinder 45, the water in the inner cavity of the descending drill cylinder 22 is discharged from the water outlet pipe 46 and flows into the ground through the one-way water outlet valve 47, after the water moistens and softens the ground below the descending drill cylinder 22, the knocking plate 42 is hammered into the ground to assist the fixation of the installation base 1;

[0058] When the water blocking rod 44 descends, the limiting plate 48 descends, thereby driving the limiting plate 48 to separate from the descending rod 25, at this time, the descending rod 25 is driven to move downward by the tension of the tension spring 49, so that the descending drill cylinder 22 does not contact with the locking rod 27 when it descends, then the staff stably installs the installation base 1 and the ground;

[0059] When the settlement occurs, the jack is used to support the support ring 54 and the mounting base 1 at this time, then the threaded rod 53 is screwed out of the inner cavity of the limiting hole 52, then the support column 51 is lifted as a whole by the jack supporting the support ring 54, at this time the distance between the support ring 54 and the mounting base 1 will increase, when the support column 51 moves upward, the total length of the support telescopic rod 36 and the telescopic sleeve rod 34 is elongated, when the support column 51 is lifted to the specified position, the threaded rod 53 is screwed into the support column 51 to limit and lock it.

[0060] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
