Embodiment Construction
[0011] From figure 1 , figure 2 It can be seen that the present invention includes a circular metal cover plate 4 made of cast iron, the metal cover plate 4 is composed of a metal plate with a thickness of 5 mm, and spiral silk lines are engraved on the outer circular wall of the cast iron metal cover plate 4. The size of the cast iron metal cover plate 4 is adapted to the size of the pile hole of the prestressed pipe pile 1; the cast iron metal cover plate 4 has two cover plate rotation holes 5 with a diameter of 10mm, and the center distance between the two cover plate rotation holes 5 is 200mm.
[0012] When the foundation is being constructed, the aluminum pile hole spiral thread 3 of the vertical strip is symmetrically installed in the upper hole of the prestressed concrete pipe pile. The pile hole spiral thread 3 is an aluminum skin with a thickness of 1mm, a width of 100mm, and a height of 2000mm. It is symmetrically arranged in the pile hole of the prestressed pipe p...

Abstract
Disclosed are a pile hole dirt preventing cast iron metal cover plate for a prestressed concrete tubular pile and a mounting method of the pile hole dirt preventing cast iron metal cover plate. The pile hole dirt preventing cast iron metal cover plate comprises a circular metal cover plate made of cast iron. Spiral threads are engraved on the outer circular wall of the cast iron metal cover plate. Two cover plate rotary holes 10mm in diameter are reserved on the cast iron cover plate. During foundation construction, vertical aluminum pile hole spiral threads are attached into the holes on the prestressed concrete tubular pile; a reinforced steel bar is made into a cover plate rotating tool with a rotating handle at the upper end and a two separated forks, which can be inserted into the cover plate rotary holes, at the lower end; and during use, the cover plate rotating tool is inserted into the rotary holes to rotate the cast iron metal cover plate downwardly through the aluminum pile hole spiral threads to a core filling height. The manufacturing and mounting method is simple, manual hole cleaning is avoided, and hole cleaning of three types of piles which need to be processed is more convenient. Pile hole dirt preventing cast iron metal cover plate is laborsaving, timesaving, economical and widely applicable.
Description
technical field [0001] The invention belongs to a soil-proof cover plate and an installation method thereof, in particular to the manufacture and construction of prestressed concrete pipe piles. technical background [0002] After the construction of existing prestressed concrete pipe piles is completed, soil will fall into the pile holes, and the pile holes need to be cleaned manually during the process of filling the pile holes, which delays the construction period and increases the project cost. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a prestressed concrete pipe pile hole soil-proof cast iron metal cover plate and its installation method, the cast iron metal cover plate is covered on the prestressed concrete pipe pile hole, to avoid pressure After the pile, the soil enters the pile hole, which saves labor and time, and does not need to manually clean the pile hole. [0004] The object of the pre...
