After reading the detailed description of the present invention in conjunction with the drawings, the features and advantages of the present invention will become more apparent.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a front view of a settlement measuring support for a foundation pile static load test in the embodiment;
FIG. 2 is a partial view I of a settlement measuring support for a foundation pile static load test in the embodiment;
fig. 3 is a partial view of a settlement measuring support for a foundation pile static load test in the embodiment.
Detailed Description
As shown in fig. 1 to 3, the settlement measuring support for the foundation pile static load test provided in this embodiment includes an inner expansion pipe 1, a support column 2, a U-shaped clamp 3, an adjusting column 4, a settlement measuring panel 5, and the like, and each component is made of a metal material.
The inner expansion pipe 1 is an internal forced expansion screw flat explosion expansion pipe. One end of the inner expansion pipe 1 is an expandable end, and the outer surface of the expandable end is provided with a friction surface. The inner expansion pipe 1 is driven into the pile body of the foundation pile, and after the expansion end expands and deforms, the static friction coefficient of the friction surface is higher, so that the maximum static friction force between the expansion end and the pile body is improved.
The other end of the inner expansion pipe 1 is a first fitting end. In this embodiment, the inner expansion pipe 1 is a tubular sleeve, and the other end of the inner expansion pipe 1 is provided with a threaded hole. One end and the first assembly end of support column 2 can be dismantled and be connected, and in this embodiment, the one end of support column 2 is provided with the second external screw thread 21 with screw hole complex. A second nut 6 is fitted on the second external thread 21.
The inner expansion pipe 1 is driven into the pile body of the foundation pile by an electric hammer, the second external threads 21 of the support column 2 are in threaded connection with the threaded holes of the inner expansion pipe 1 and are fastened through the second nuts 6, and therefore the support is simply and quickly mounted on the pile body of the foundation pile.
3 parcel support column 2's of U-shaped card the body of rod, first pilot hole has all been seted up at the both ends of U-shaped card 3, is equipped with adjusting bolt 7 in the two first pilot holes on the U-shaped card 3, and adjusting bolt 7's one end is provided with first external screw thread, is equipped with first nut 8 on the first external screw thread, and adjusting bolt 7's the other end is provided with the assembly seat, has seted up the second pilot hole on the assembly seat, inserts regulation post 4 in the second pilot hole.
