It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 3, the present application relates to a fixing member for a soft soil roadbed widening structure, comprising: the support bar comprises a support bar 1 and at least one fixing piece 2, wherein the fixing piece 2 comprises a connecting end 21 and a free end 22, and the connecting end 21 is hinged to the support bar 1.
The supporting rod 1 is buried in the soft soil layer, the stress area is increased through the fixing sheet 2, the compression resistance of the soft soil layer is adjusted, and the aim of adjusting the sinking speed is achieved indirectly.
When the anchor is settled with the soft soil layer, since the settlement of the soft soil layer is a state of being compressed while being settled, the angle of the anchor 2 in the soil is necessarily changed as the soft soil layer is compressed. The connecting end 21 of the fixing plate 2 is hinged with the supporting rod 1. So that the stator plate 2 can be rotated centering on the hinge point, thereby displacing the free end. To reduce the resistance encountered by the free end during displacement, in one embodiment of the present application, the free end is spherical.
If the angle of the fixing sheet 2 is left to vary, the vertical force capacity of the fixing sheet 2 becomes gradually smaller when the free end 22 of the fixing sheet 2 is higher than the attachment end 21. In order to avoid this, in an embodiment of the present application, the fixing member for a soft soil roadbed widening structure further includes: and the limiting part 3 is arranged on the support rod 1 and is positioned on the upper side of the connecting end 21. Because the existence of spacing portion 3 for the free end is the same with the height of link, and the stationary blade 2 supports spacing portion 3 and makes stationary blade 2 can not continue to rise this moment. Thereby keeping the force bearing capacity of the fixing sheet in the vertical direction to the maximum.
In an embodiment of this application, the bracing piece is the screw rod, and the outer wall is equipped with the screw thread, a mounting for soft soil roadbed widens structure still includes: a sleeve 4, a connecting portion 5 and at least one through hole 6. Wherein the inner wall of the sleeve 4 is provided with an internal thread, the screw rod is arranged inside the sleeve, and the external thread is matched with the internal thread, so that the screw rod moves axially along the sleeve 4 inside the sleeve 4; the connecting part 5 is connected with one end of the screw rod facing the interior of the sleeve; at least one perforation 6 is arranged on the pipe wall of the sleeve 4, the at least one fixing sheet 2 penetrates through the perforation 6 in a one-to-one correspondence mode, the connecting end 21 is hinged to the connecting portion 5, the screw rod drives the connecting portion 5, and then the connecting end 21 is driven to move axially along the sleeve inside the sleeve 4.
The screw rod moves up and down in the sleeve to drive the connecting part 5 to move up and down, so that the angle of the fixing piece 2 when the fixing piece is embedded into a soft soil layer is adjusted to achieve the speed of indirect settlement control. In addition, if the casing is long enough, it can protrude out of the ground. The angle of the fixing sheet 2 can be adjusted in real time by the adjusting screw rod in the process of descending the soft soil layer, so that the purpose of adjusting the stress capacity in time is achieved. In the present embodiment, the size and shape of the through hole 6 are not limited. Thus, the through-hole 6 may be set to the same width as the fixing sheet 2 so that the fixing sheet 2 can directly pass through the through-hole 6 and start working. When the width of perforation 6 is less than the width of stationary blade, can wear out the stationary blade vertically earlier, or follow the perforation direction and wear out afterwards and begin work with it tiling in soft soil layer again, all belong to this application claimed the scope.
In an embodiment of the present application, the bottom end of the supporting rod is a cone.
In one embodiment of the present application, the bottom end of the cannula is a cone.
In an embodiment of the present application, the number of the through holes is 4, and the number of the fixing pieces is 4.
In an embodiment of the present application, the through holes are uniformly distributed in the circumferential direction of the sleeve, and the fixing pieces are uniformly distributed in the circumferential direction of the connecting portion.
In an embodiment of the present application, the screw and the connecting portion are freely rotatable. Thus, when the screw rod is rotated, the connecting part does not need to be driven to rotate at the same time.
In an embodiment of the present application, the number of the limiting portions is 4, and the limiting portions are correspondingly disposed on the supporting rods.
The application provides a mounting for soft soil roadbed widens structure buries this mounting in soft soil layer, increases the ability of bearing the pressure from the road surface through the stationary blade, can slow down the roadbed and sink. Meanwhile, when the fixing piece is buried in the soft soil, the bearing capacity of the contact surface of the fixing piece and the soft soil layer in the vertical direction can be controlled by adjusting the angle of the fixing piece, and the purpose of adjusting the sinking speed is further achieved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
