Detailed Description
The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.
As shown in fig. 1-4, the steerable steel support connecting piece between the manual hole digging retaining piles comprises a first pile foundation 1 and a second pile foundation 2, wherein a connecting platform 3 is formed on the first pile foundation 1 and the second pile foundation 2, a steering support 5 is fixed on the connecting platform 3 through a steering base 4, a steering head 6 is embedded in the steering support 5, a support steel pipe 7 is welded on the steering head 6, and the support steel pipe 7 on the first pile foundation 1 can be in direct connection with the support steel pipe 7 on the second pile foundation 2 after being in rotary alignment.
In this embodiment, in order to reduce the construction process and improve the structural strength, the connecting platform 3 is integrally cast with the first pile foundation 1 or the second pile foundation 2, and specifically, the connecting platform 3 is formed by embedding anchor bars 8 in the pile foundations and then casting concrete.
As shown in fig. 1 and 2, the steering base 4 is formed with a limiting clamping groove 10 through a limiting ring 9, the steering support 5 is formed with a limiting step 11 adapted to the limiting clamping groove 10, and the steering support 5 and the steering base 4 are clamped through the matching of the limiting clamping groove 10 and the limiting step 11.
Furthermore, the steering base 4 is hermetically connected with the steering support 5, an oil storage chamber 12 is arranged in the steering head 6, and oil is filled in the oil storage chamber 12 to play roles of lubrication and damping; the oil storage chamber 12 is communicated with the inner cavity of the steering support 5, and a sealing rubber ring 13 is annularly arranged between the steering head 6 and the steering support 5 to prevent oil from leaking.
Preferably, the steering head 6 is connected with a support top platform 14 which is a plane steel plate, the support top platform 14 is welded with the support steel pipe 7, that is, the end surface of the support steel pipe 7 is fixedly connected with the support top platform 14, and the periphery of the support steel pipe 7 is also connected with the support top platform 14 through a plurality of stiffening rib plates 15.
Further, the supporting steel pipe 7 on the first pile foundation 1 is connected with the supporting steel pipe 7 on the second pile foundation 2 through a flange 16 and a bolt 17.
During specific implementation, firstly, the embedded anchor bars 8 are arranged on the pile foundation, then the concrete platform is poured to form the connecting platform 3, the first pile foundation 1 of the retaining pile, the second pile foundation 2, the connecting platform 3 and the steering base 4 are connected into a whole through the embedded parts, then the steering support 5 is installed on the steering base 4, then the support steel pipe 7 is connected on the support top platform 14 connected on the steering head 6 through bolts, and then the support steel pipe 7 and the stiffening rib plate 15 are welded in a surrounding mode. After the first pile foundation 1 and the second pile foundation 2 on two sides are prepared, the supporting steel pipe 7 is cut, then is rotated and aligned, and finally is connected with the bolt 17 through the flange 16. The support steel pipe 7 in this embodiment can rotate in a certain angle through turning to the support 5, and the slippage on the base 4 is followed to turning to because of the space angle problem when avoiding directly supporting with a whole steel pipe, makes things convenient for the setting that the pile foundation supported.
The advantage of this example lies in receiving the influence of topography very little, all can use under the circumstances such as pile foundation not counterpoint, connects more stably, and industrialization degree is high, and parts such as ball pivot support can all recycle moreover, compares in the influence of other modes to the cost very little.
The technical scheme provided by the utility model is introduced in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
