Embodiment Construction

[0039] The present invention is described in detail below in conjunction with accompanying drawing:

[0040] Such as Figure 1-2 As shown, the detailed drawing of the ribbed prestressed pipe pile connection includes the upper ribbed prestressed pipe pile 1, the end plate 2 with internal threads, the end plate 3 with external threads, and the internal thread of the end plate with internal threads Recessed threads, male threaded end plates with protruding male threads. The lower ribbed prestressed pipe pile 4 and the closed end plate 5. When the ribbed prestressed pipe pile is connected to the pile, fix the lower section of the ribbed prestressed pipe pile 4 with a clamp, rotate the upper section of the ribbed prestressed pipe pile 1, and place the upper section of the ribbed prestressed pipe pile 1 in the belt. The threaded end plate 2 is screwed into the externally threaded end plate 3 of the ribbed prestressed pipe pile 4 at the lower part. After correcting its verticality...

Abstract

The invention discloses a ribbed prestressed pipe pile, and a manufacturing method and a drilling-planting construction process thereof. The ribbed prestressed pipe pile comprises an upper ribbed prestressed pipe pile and a plurality of lower ribbed prestressed pipe piles. The upper and lower ends of each lower ribbed prestressed pipe pile are provided with an external thread end plate and a closed end plate. Two ends of the upper ribbed prestressed pipe pile are provided with an external thread end plate and an internal thread end plate. According to the drilling-planting construction process, gravels are placed at the bottom of the pile and around the pile, grout is injected to the bottom of the pile and around the pile, and accordingly, limit bearing capacity of the single pile can be improved significantly and piles are saved. In addition, an injection pipe can be recycled after grout injection, so that fewer injection pipes are needed.

Description

technical field [0001] The invention relates to a ribbed prestressed pipe pile, a manufacturing method thereof, and a drilling and planting construction technology. Background technique [0002] Prestressed pipe piles have been widely used due to their advantages of reliable pile quality, factory production, fast construction speed and reasonable economy. , The joints are prone to corrosion damage and low tensile strength. In actual engineering, engineering accidents such as displacement of pipe piles or even broken piles due to pile driving effect occur from time to time. The vibration and earth-squeezing effect produced by piling will also have a great impact on the normal life of surrounding buildings and residents, and even cause cracks in adjacent buildings. At the same time, when common prestressed pipe piles are piled, the end plates are exposed to groundwater or wet soil layers. When constructing in corrosive groundwater and soil layers, the joints of pipe piles a...
