Preferably, the limiting blocks at two sides are respectively attached to grooves of the left rib and the right rib.
Preferably, stirrups are arranged inside the upper concrete structure, the left rib and the right rib.
Preferably, grooves are formed in the bottoms of the left rib and the right rib respectively.
Preferably, two sides of the bottom end of the upper concrete structure are fixedly connected with the left rib and the right rib respectively.
The novel prestressed concrete foundation pit support pile provided by the utility model has the beneficial effects that: carry out the joint through between both sides upper portion concrete structure through first connecting block and the second connecting block, the stopper of both sides through coming from the base top simultaneously to the fender pile of both sides is connected, restricts through the spread groove of first connecting block and second connecting block, and the stopper of both sides restricts the recess of left rib and right rib that upper portion concrete structure bottom of both sides corresponds, thereby prevents to appear the gap between the fender pile connection of both sides, thereby has improved the quality of row stake.
