Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present invention based on the embodiments of the present invention.
Fig. 1 and 2 show a group of diagonal pile models according to an embodiment of the present application, where the group of diagonal pile models includes a pile cap 2, a tilt angle adjusting device 1 fixed at the bottom of the pile cap 2, and a model pile 3 connected to the end of the tilt angle adjusting device 1.
As shown in fig. 3, the reclining device 1 includes an anchor plate 10, an angle conversion joint 11, and a staking joint 12.
Referring to fig. 4, anchorage plate 10 is a rectangular parallelepiped and is made of a strong metal such as steel or an aluminum alloy. An anchor bolt hole 400 is formed in the center of the upper end surface of the anchor plate 10, and the anchor bolt hole 400 is used for fixedly connecting the anchor plate 10 with the bearing plate 20 through the bearing plate anchor bolt 40. The anchor plate 10 is provided with anchor plate rotation shaft bolt holes 410 penetrating from front to back, and the anchor plate rotation shaft bolt holes 410 are located on the middle line of the anchor plate 10 for fixing the rotation shaft bolts 41. A series of anchor plate tilt positioning bolt holes 420 are also formed in anchor plate 10 about anchor plate rotation axis bolt holes 410, anchor plate tilt positioning bolt holes 420 being used to secure tilt positioning bolts 42.
Referring to fig. 5, the angle conversion connector 11 is a "U" shaped member, and is also made of a metal with high strength such as steel or aluminum alloy, and the U-shaped groove of the angle conversion connector 11 is adapted to the anchor plate 10. Chamfering is arranged at four corners of the upper end of the angle conversion joint 11. A crossover joint rotation shaft bolt hole 411 is preset in a grooved section of the angle crossover joint 11, the crossover joint rotation shaft bolt hole 411 is on a midline of the angle crossover joint 11, and a series of crossover joint inclination angle marking bolt holes 421 are preset around the crossover joint rotation shaft bolt hole 411 on the angle crossover joint 11. In this embodiment, the adapter rotation shaft bolt hole 411 and the adapter inclination angle marking bolt hole 421 are provided in pairs at both wings of the grooved section of the angle adapter 11.
The anchor plate 10 is fixedly connected with the angle conversion joint 11 through a rotation shaft bolt 41 and an inclination angle positioning bolt 42. Chamfers are provided at both end points of the lower end of the anchor plate 10 to ensure that the chamfers do not touch the bottom of the U-shaped groove of the angle conversion joint 11 when the anchor plate 10 rotates around the rotation shaft bolt 41. The depth of the U-shaped groove of the angle conversion connector 11, the position height of the rotary shaft bolt hole 411 of the conversion connector and the position height of the rotary shaft bolt hole 410 of the anchoring plate are designed to ensure that the anchoring plate 10 can freely rotate without touching the bottom of the U-shaped groove when being embedded into the U-shaped groove of the angle conversion connector 11 and taking the rotary shaft bolt 41 as the rotation center.
Further, referring to fig. 6, the method for determining the adaptor tilt mark bolt hole 421 and the anchor plate tilt positioning bolt hole 420 is as follows:
the rotation axis bolt 41 is taken as a rotation center point, the included angle between the center line of the outer surface of the anchoring plate 10 and the center line of the outer surface of the angle conversion joint 11 in the plane is the inclination angle of the model pile 3, and the conversion joint inclination angle marking bolt holes 421 for locking the inclination angle of the model pile 3 are preset at any positions on two sides of the center line of the outer surface of the slotted section of the angle conversion joint 11. Then, adapter tilt index bolt hole 421 presets a mating anchor plate tilt locating bolt hole 420 at the planar projection of anchor plate 10. And so on, a series of anchor plate inclination angle positioning bolt holes 420 and adapter inclination angle marking bolt holes 421 are preset on the anchor plate 10 and the angle adapter 11 according to the requirements of different inclination angles.
It should be noted that, the included angles between the two circular center lines of the two hole center lines of the bolt hole 421 of the tilt mark of the adapter and the bolt hole 411 of the rotation shaft of the adapter and the central line of the outer surface of the angle adapter 11 are not necessarily the true inclination angle of the model pile 3, but only the anchor plate 10 and the angle adapter 11 are fixed by the inclination angle of the model pile 3 for facilitating the hole opening, so the hole opening positions of the bolt hole 421 of the tilt mark of the adapter are determined according to the requirement, and generally the two sides of the central line of the outer surface of the angle adapter 11 are arranged in a scattered manner, meanwhile, the distances between the bolt hole 421 of the tilt mark of the adapter and the bolt hole 411 of the rotation shaft of the adapter can be inconsistent, so as to avoid the too dense hole opening of the bolt hole 421 of the tilt mark of the adapter caused by too small angle interval, and further cause the stress damage of the bolt hole 421 of the tilt mark of the adapter in the loading process, or the bolt hole 421 of the tilt mark of the adapter cannot be arranged. And, facilitate the bolt tightening operation.
Fig. 7 shows a schematic structural view of the scarf joint 12, wherein the scarf joint 12 comprises a scarf sleeve 120, a connecting base 121 and a locking device 122.

The embedded sleeve 120 and the connecting base 121 are fixedly connected to form a whole by taking the slotting level as a requirement.
The locking device 122 comprises nuts fixed to two sides of the slit respectively and a threaded rod connecting the two nuts. The two nuts are positioned at the same level and fixed on the embedded sleeve 120, or fixed on the connecting base 121, or fixed at the joint of the two nuts.
In this embodiment, the material of the embedded joint 12 is the same as the material of the anchor plate 10 and the angle conversion joint 11. The height of the embedded sleeve 120 is added with the thickness of the connecting base 121, and is at least 1 time as large as the outer diameter of the model pile 3. The caulking joint 12 is fixedly connected with the angle conversion joint 11 by bolts at both ends of the connection base 121.
