Abstract

The utility model discloses a breast wall of a prefabricated concrete pipe of a manual hole digging pile; the breast wall comprises an upper concrete pipe, a plurality of intermediate concrete pipes and a lower concrete pipe which are connected end to end, wherein, the lower end of the upper concrete pipe is provided with an inner step surface, the upper end of the intermediate concrete pipe is provided with an outer step surface which is distributed in a ring shape, a low plane at the outside of the outer step surface is mounted with an embedded iron piece, the lower end of the intermediate concrete pipe is provided with the inner step surface which is distributed in a ring shape, the upper end of the lower concrete pipe is provided with the inner step surface which is distributed in a ring shape, the lower end of the lower concrete pipe is provided with a foot blade, the inner side of the foot blade is provided with an oblique plane which is expanded outwards, the outer side of the foot blade is provided with a projection; the side walls of the upper concrete pipe, the intermediate concrete pipes and the lower concrete pipe are all embedded with drainage tubes which are obliquelydistributed from low internal side to high external side. The breast wall of the prefabricated concrete pipe of the manual hole digging pile which is formed by connection of the upper concrete pipe,the plurality of intermediate concrete pipes and the lower concrete pipe can effectively reinforce the side wall of the pile hole; therefore, the breast wall can separate the inside of the pile hole and the quicksand even in the serious quicksand region, and ensures the integrity of the pile hole, and makes the pile body formed through casting have better quality.

Description

A kind of prefabricated concrete of hand excavated pile is managed and protected wall

Technical field

The utility model relates to a kind of prefabricated concrete of hand excavated pile and manages and protects wall.

Background technology

Tradition hand excavated pile panelling construction technology is Cast-in-place concrete retaining wall in the stake hole generally, treats that Cast-in-place concrete reaches after certain length of time form removal pouring pile concrete again, if but just the Cast-in-place concrete retaining wall can't be constructed when quicksand is serious, thus can not guarantee pore-forming.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of collapse prefabricated concrete of hand excavated pile in hole of a hole that can effectively prevent and manages and protects wall.

For this reason, the prefabricated concrete of the hand excavated pile that the utility model provides is managed and protected wall and is gone up the concrete pipe by a joint, the linking of concrete pipe formed under concrete pipe and saved in the middle of the more piece, the lower end of wherein going up the concrete pipe has interior cascaded surface, the upper end of middle concrete pipe has the outer cascaded surface of annular spread, the lower end of middle concrete pipe has the interior cascaded surface of annular spread, the upper end of following concrete pipe has the interior cascaded surface of annular spread, the lower end of following concrete pipe has the sword pin, the inboard of sword pin has the inclined-plane that expands outwardly, the outside of sword pin has projection, last concrete pipe, all be embedded with the drainage tube that low outer height diagonally distributes in being on the sidewall of middle concrete pipe and following concrete pipe.

Since the utility model provide by concrete pipe in the middle of the last concrete pipe, more piece and a joint down the concrete pipe be connected the prefabricated concrete that forms and manage and protect wall energy and enough effectively reinforces a hole sidewall, even the zone serious at drift sand also can intercept an inside, hole and a drift sand, guarantee the integrality in stake hole, thereby the pile quality that cast is obtained is better.
