Diaphragm wall apparatus and methods

摘要

The invention relates to apparatus and methods and kits for constructing walls such as diaphragm walls comprising one or more panels and walls so constructed. In particular the invention relates to apparatus, methods and diaphragm walls having a guideway along a height of a first wall of a pane). More particularly, the invention relates to an apparatus for constructing a diaphragm wall comprising: a guideway tube along a height of a first wall of a first concrete panel; a sacrificial wall element in the guideway tube that extends along the tube and about a portion of a periphery of the tube; a cutting mechanism for cutting along the height of a first wall of the first concrete panel, the cutting mechanism being arranged to cut along the height of the wall of the first concrete panel and along the sacrificial wall element of the guideway tube so as to cut away at least part of the sacrificial wall element of the guideway tube along at least part of the height of the first wall. The invention further relates to a comprising: casting a guideway tube into a first concrete panel along a height of a first wall of the panel; cutting along the height of the first wall of the panel; cutting along at least part of the length of the sacrificial wall element of the guideway tube; pouring a second concrete panel, including pouring concrete into the cutaway guideway tube. The invention further provides a diaphragm wall comprising at least two or a series of concrete panels adjoining one another.

主权项

1. An apparatus for constructing a wall comprising:
at least one guideway tube along a height of a first wall of a first concrete panel and in which the at least one guideway tube is hollow, wherein the at least one guideway tube comprises a sacrificial wall element that extends along the at least one guideway tube and about at least a portion of a periphery of the at least one guideway tube; and at least one cutting mechanism configured to cut along the height of the first wall of the first concrete panel, the at least one cutting mechanism being arranged to cut along the height of the wall of the first concrete panel and along the sacrificial wall element of the at least one guideway tube so as to cut at least part of the sacrificial wall element of the at least one guideway tube to form an aperture in the at least one guideway tube along at least part of the height of the first wall to allow ingress of concrete into the at least one guideway tube.
