Abstract
An underground continuous wall building method and apparatus in which a chain cutter 2 provided with excavation blades is obliquely mounted on a running carriage 1. Slanting continuous trenches G1, G2 are excavated by moving the running carriage 1 in a transverse direction while rotating the cutter 2 with the cutter 2 obliquely placed in the ground, and a water cutoff material is poured into the excavated continuous trenches G1, G2 and solidified therein to build slanting continuous walls R1, R2 in the ground.

A method for building an underground continuous wall, comprising the steps of:
- placing a chain cutter carried by a running carriage obliquely in ground by sliding the chain cutter in an oblique direction by a hydraulic cylinder;
- moving the running carriage along a specified course over the ground, said running carriage carrying the chain cutter fixedly held in the oblique direction in the ground, said chain cutter being driven to form a first continuous slanting trench and a second continuous oppositely slanting trench;
- excavating the first and the second continuous slanting trenches so as to form an inverted V cross section separated at an apex thereof;
- pouring a wall material into the first and second continuous trenches in order to build two continuous walls with an inverted V cross section;
- and
- placing a slightly arcuate roof bridging the apex of the two continuous walls with the inverted V cross section above an underground construction.

- moving the running carriage along a specified course over the ground, said running carriage carrying the chain cutter fixedly held in the oblique direction in the ground, said chain cutter being driven to form a first continuous slanting trench and a second continuous crossing trench;
- building a plurality of vertical walls in the ground;
- excavating the first continuous slanting trench and the second continuous crossing trench between the vertical walls built in the ground;
- and
- pouring a wall material into the first and second continuous trenches in order to build a X-shaped wall for reinforcement between the vertical walls.
A method for building an underground continuous wall, comprising the steps of:

- building two vertical walls at a specified spacing in the ground;
- undercutting at an angle and then excavating the continuous slanting trench so as to extend underneath the two vertical walls;
- and
- pouring a wall material into the continuous trench in order to build a slanting continuous cutoff bottom wall for preventing entry of water from below into a region between the two vertical walls.
