Embodiment Construction

[0018] A method for reinforcing and repairing pipe pile heads, characterized in that:

[0019] Step 1) Remove the damaged and loose concrete, expose the main reinforcement 3-4cm and straighten it to make it vertical to the ground, and saw off the concrete at the damaged pile head, and then saw off the concrete; then wash away the floating ash and the soil on the surface of the concrete, After drying, add a pile cap of the same specification on the pile head, and connect the exposed main reinforcement with the pile cap.

[0020] The pile cap includes: a circular end plate 11, and a cylindrical steel ferrule 12 is set on the circular end plate 11. The surface of the circular end plate 11 is coplanar with the end surface of the cylindrical steel ferrule 12 and the circular end plate 11 Connected with the cylindrical steel ferrule 12, an end plate screw hole 111 is provided on the circular end plate 11, and a ring rib 13 is also provided between the circular end plate 11 and the c...

Abstract

The invention provides a method for strengthening and repairing a tubular pile head. The method comprises the following steps: cleaning broken and loose concrete, exposing main reinforcement for 3 to 4cm, regulating the main reinforcement to ensure that the main reinforcement is vertical to the ground; sawing off the broken pile head, and flat sawing the pile head; washing float ash and dust on the surface of the concrete, drying the concrete, and covering a pile cap with the same specification on the pile head; connecting the exposed main reinforcement with the pile cap, and placing a pallet matched with the pile cap in an inner cavity of the tubular pile; connecting the pallet with the pile cap; and finally, filling epoxy resin concrete in a cavity formed by the pallet, an annular end plate and the inner wall of the tubular pile, and continuously connecting the epoxy resin concrete with a sunk pile after curing in 4 hours. The pile cap comprises the annular end plate, wherein a cylindrical steel hoop is sleeved on the annular end plate; the surface of the annular end plate and the end surface of the cylindrical steel hoop are coplanar, and the annular end plate and the cylindrical steel hoop are connected; the annular end plate is provided with end plate screw holes; and the connection of the exposed main reinforcement and the pile cap is to weld the exposed main reinforcement onto the end plate screw holes one by one.

Description

technical field [0001] The invention relates to a pile joint technology in the field of construction according to construction requirements for the length of a concrete foundation pile after the pile head is damaged during the construction process, and in particular relates to a method for reinforcing and repairing a pile head of a pipe pile. Background technique [0002] With the increasing importance of modern buildings and the continuous increase in building height. Higher requirements are put forward for the bearing capacity of the foundation. The natural foundation can no longer bear the load from the upper building, so the natural foundation is used, and there is a way to deal with it, that is, to use reinforced concrete as the foundation of the foundation Pile, the pile is pressed into the ground with a pile driver to become a foundation pile, and the upper part of the foundation pile bears the building. my country has stipulated corresponding standards for the desig...
