Abstract
Abstract Proposed is a method of erecting long straggling subterraneous buildings within an open ditch, comprising the steps of excavating the earth at the end face of the ditch by means of a digging machine which is advanced substantially continuously, supporting the lateral walls of the ditch in the region adjacent the end face by prop pieces which are moved forward together with the digging machine, sectionwise building-in the building from prefabricated parts directly behind the digging machine in the free space between the prop pieces at the bottom of the ditch, supporting the lateral walls of the ditch in a region located behind the prop pieces, and subsequently filling the ditch again over the building.

Claim 1
Independent Claim
201 words
Method for erecting a long straggling subterraneous construction within an open ditch comprising the steps of: excavating the earth at the front end of said ditch by means of a substantially continuously advanced excavating machine; propping the sidewalls of said ditch in the region adjacent and extending rearwardly from said front end by means of prop members on either side of said ditch, said prop members extending rearwardly from said excavating machine a predetermined distance and attached to said excavating machine for forward movement therewith; forming said construction sectionwise from prefabricated sections on the bottom of said ditch substantially within the free space interposed between said prop members, filling the space between the respective sidewalls of said ditch and said construction to thereby support the sidewalls of said ditch behind said prop members in the region from the bottom said ditch to the height of said construction, said space being formed behind said prop members as said excavating machine moves forward; inserting removable vertical planks along said sidewalls above said construction to thereby support said sidewalls of said ditch in the region from the top of said construction to the top of said ditch; and refilling the ditch above the construction.

Method for erecting a long straggling subterraneous construction within an open ditch comprising the steps of: excavating the earth at the front end of said ditch by means of a substantially continuously advanced excavating machine; propping the sidewalls of said ditch in the region adjacent and extending rearwardly from said front end by means of prop members on either side of said ditch, said prop members extending rearwardly from said excavating machine a predetermined distance and attached to said excavating machine for forward movement therewith; forming said construction sectionwise from prefabricated sections on the bottom of said ditch substantially within the free space interposed between said prop members, filling the space between the respective sidewalls of said ditch and said construction to thereby support the sidewalls of said ditch behind said prop members in the region from the bottom said ditch to the height of said construction, said space being formed behind said prop members as said excavating machine moves forward; inserting removable vertical planks along said sidewalls above said construction to thereby support said sidewalls of said ditch in the region from the top of said construction to the top of said ditch; and refilling the ditch above the construction.
Claim 3
Dependent Claim
50 words
The method recited in claim 1 and further comprising the steps of: wedging the bottom ends of said vertical planks against the top of said construction; and bracing said planks adjacent the top of said ditch by means of stiffening members extending across said ditch between opposite sets of planks.
Claim 4
Dependent Claim
54 words
The method recited in claim 2 and further comprising the steps of: removing said planks in the rearward regions of said ditch after said refilling step has been accomplished; filling the hollow spaces resulting from the removal of said planks; and transporting said planks forward to a position behind said excavating machine for reuse.
Claim 5
Dependent Claim
45 words
The method recited in claim 1 wherein said refilling step is carried out substantially continuously in accordance with the advancement of said excavating Machine in the form of a ramp sloping from the rearward end of said ditch toward said front end of said ditch.
Claim 6
Dependent Claim
70 words
The method recited in claim 1 and further comprising the steps of: prefabricating disassemblable sections of said construction at a location remote from said ditch; disassembling said construction sections into more easily transportable elements; transporting said elements to an assembly station in the vicinity of said ditch; and reassembling said parts to form prefabricated sections of said construction in preparation for the step of forming said construction in said ditch.
Claim 7
Dependent Claim
128 words
Method in accordance with claim 1 in which said propping of the sidewalls of the ditch in the region rearwardly of a ditch section lying behind the prop members is arranged at least in a region of the ditch lying above said construction by means of vertical planks the lower ends of which are secured against the sidewalls of the ditch taking abutment on parts of the construction and the upper ends of which are secured against the sidewalls of the ditch by means of stiffening members extending across the ditch and taking abutment on the planks on the respective opposite sides of the ditch, said planks being inserted at both sides of the ditch against drag plates being connected to and moving together with the excavating machine.
