- The invention relates to apparatuses and methods for excavating the ground to construct-in-place of a continuous narrow excavation an underground structure, such as anchor and foundation, draining and retaining stratum and wall especially to control of ground gas and water flow and to provide drainage, isolation, containment, and separation of subsurface environments, prevention of leakage through levees and isolation of contaminated and sensitive areas.
- In constructing a curved surfacial and narrow underground wall according to a prior art technique, first a hole of an elliptical cross-section having a 2 to 3 m major axis is dug in the ground to a predetermined depth by a powerful bucket or a hole is dug to a predetermined depth by two or three series of auger drills. After the hole formed in slurry is sealed with a bentonite solution to prevent further penetration of slurry, a reinforcing bar cage is placed in the hole and a ready mixed-concrete is then poured into the hole to form a foundation column. Such a method is repeated to form an underground continuous wall. Slurry or bentonite solution layers interrupt the formation of the continuous wall so that after completion of the wall, ground water tends to leak into the inside of the continuous walls through the joints. It is therefore very difficult to provide the underground continuous wall simultaneously having two functions as foundation wall and a diaphragm wall.
- There is known to use an excavator disclosed in U.S. Pat. No. 5,244,315 for constructing an underground continuous wall, including a travelling trolley, supporting frames, an extensible guide post vertically supported by a tiltable frame on the trolley, and an endless chain cutter and agitator. The cutter excavates a trench, jets a hardening liquid in a hole and mixes the liquid with the earth and sand in the hole to form a soil cement wall. Significant defects of the excavator and method of its advancement are: 1) the excavator is not capable to form a wall in the unstable ground and a horizontal stratum; 2) the cantilever chain cutter being advanced that requires a huge traction force and stabilizing moment applied to the trolley; 3) the cutter carries the mixture out of the trench; 4) the cutter is not capable to compress the working front face of the wall being formed.
- There is also disclosed in U.S. Pat. No. 5,685,668 an apparatus for delivering an unrolling liner material into and along a trench being formed of a depth up to sixty feet that prevents side wall collapse in a subsurface water saturated zone and forms a barrier wall. Significant defects of that barrier wall installation system are as shown above and following: 1) a wall may be shaped into plane and vertical cylindrical surfaces only because of the cylindrical shape of a roll of the liner material; 2) it is difficult to use a very wide liner material of width that is sufficient to reach a deep impermeable ground layer.
- It is known a means for steering a cable-laying apparatus disclosed in U.S. Pat. No. 5,934,833, the steering means mounted securely to a frame of the chassis of the apparatus to allow excavating the curvilinear slit trench by turning break the frame about a central vertical hinge disposed between to turn relatively front driving wheels and a rear driven wheel, that is difficult because the steering is carried out, while the apparatus advances and the driving front wheels must provide large road-holding capacity.
- To decrease the huge intended traction and stabilizing moment for the constructing means that must be created by the chassis it is well-known a slit trench digging apparatus disclosed in U.S. Pat. No. 3,638,338 and provided with a disposed vertically slit trenching blade being capable of oscillating about a vertical axis to form a slit trench and expanding reciprocatingly aside to compact the side walls and widen the trench being advanced, so though there are common defects necessiated with forced applying a huge torque to the blade and its cheeks from above the ground level, and large friction resistance by the compacted walls to the advancement of the blade; as well as utilizing an advanceable and trench side walls-supporting shield disclosed in U.S. Pat. No. 3,994,139 and adapted for laying a pipeline into a rectilinear trench, where the shield being composed of a set of the longitudinally displaceable elongate cutting and side wall-supporting members, a frame for supporting and guiding the members and ram means for effecting relative movement between the frame and the members to effect advancement of the trench. In operation, the ram means advance the members in relation to the frame so as to excavate a trench, and other ram means for the members not being advanced are blocked and holding the remainder of the shield, including the frame, that is stationary until all of the members have been advanced, and then the ram means shift the frame in the advancing direction. Significant defects of the shield and method of its advancement are: 1) the members and trench, on the one hand, and the frame and the pipeline, on the other hand, are advanced alternately and interruptible at a lesser mean speed because frequent standing idles; 2) advancement of the frame is not secured because stopping the advanced members and their firm frictional contact with the walls is not secured, especially in the unstable wet or stony ground, and 3) the shield is not capable of advancing a curvilinear trench section.
