Description

A kind of prestressed concrete pipe pile being easy to pile sinking
Technical field
The utility model relates to a kind of concrete tubular pile, in particular to a kind of prestressed concrete pipe pile for being easy to pile sinking.
Background technique
Prestressed concrete pipe pile can be divided into post-tensioned prestressing stake and pretensioned-prestressed tube pile.Pretensioned prestressing Tubular pole is using a kind of hollow cylinder elongate concrete prefabricated components made of pretensioned prestressing technique and centrifugal casting, master It to be made of cylinder-shaped pile body, end plate and steel hoop etc..Concrete tubular pile has cross, pyramid type and open-type.It is cross Closed type is also referred to as with pyramid type.District of Shanghai is relatively more using open-type pile top (boots), and Guangdong and Hong Kong and Macao, using cross Type pile top (boots) is more.There are about 1/3 long inner cavities to be clogged by the soil body for pile body lower part after open-type pile top (boots) sinks to soil layer, sinks The soil-squeezing action occurred when stake is more smaller than sealing type pile top (boots).But sealing type pile top is sunk in soil layer, and pile body inner cavity exists It is very clear under the irradiation of electric light and flashlight light, therefore, can use ocular estimate check pile pile quality, and with directly measurement method Repetition measurement pile sinking length.Pile top off-gauge closes design requirement, will also result in accident resulting from poor quality of projects, so Guangdong standard《Prestressing force Pipe pile foundation technical regulation》DBJ15-22-98 has made regulation to common pile top specification.There are many tubular pole pile sinking process, at me The method that the country of state constructed has:Hammering method, static pressure method, lash method, water jetting, prebored hole method and middle pick method etc., and with static pressure Method is with the most use.Due to diesel hammer piling when vibration acutely, noise it is big, for adapt to urban district construction need, China was each in recent years Ground develops the technique of the static pile press pressure pile for prestressed pipe of large-tonnage, and static pile press can be divided into roof pressing type again and embrace pressure Formula, hugging pressure type are that the clamping plate of a machine clamps pile body, are worked by the principle that the frictional force for holding plate is greater than soil-entering resistance, static press piling Machine maximum pile driving pressure needs 5000-6000KN that the pile for prestressed pipe of diameter 500-600 could be pressed onto the supporting course of design requirement, So just there is very high power demand to pressing machine, therefore it is desirable to have a kind of prestressed concrete pipe pile for being easy to pile sinking It constructs, to improve the quality and stability of prestressed concrete pipe pile, and reduces construction volume.
