M. B. BL, KOMMANDITGESELL SCHAIT, OF SIEMENSSTADT, NEAR BERLIN, GERMANY, A CORPORATION OF GER- MANY PROCESS OF CONNECTING SOLIDIFIED FOUNDATION I SOIL TO BUILDING STRUCTURES AND THE STRUCTURE PRODUCED THEREBY Application filed January 30, 1931, Serial No. 512,378, and in Germany April 11, 1930.

, crete or of stone, brick or the like, which is n- IJIJ erected on the foundation soil.

In carrying out solidifying work the fastening between the solidified foundation soil and the constructional parts of concrete or stone, brick and the like, which are erected on the foundation soil is deficient in many cases and gives rise to trouble in the structure.

According to the present invention the connection between the foundation soil and the erected structure is improved and simplified by leaving the tubes, used for the injection of the solidifying substances, in the solidified foundation soil and by embedding their projecting upper ends to the constructional part which is erected on the foundation soil. 7

In the accompanying drawings Figure 1 is a vertical section through a construction according to one embodiment of the invention, and

Figure 2 is a similar view of anotherembodiment of the invention.

In Figure 1 are shown sheet pilings 1 and 2 between which lies the foundation block 3. The foundation body 3 is to be understood as soil material artificially solidified, for example, by the introduction of chemicals which convert the loose soil into artificial rock. Before or during the solidification, iron rods 1 are inserted in the ground which is to be solidified. These iron rods 4 project at their free ends from the foundation body, and may be bent, as indicated at 5, and embedded in the concrete or masonry 6 when V the latter is formed.

In Figure 2 a somewhat different embodiment of the invention is illustrated. Instead of the iron rods 4, the pipes 7, which serve for the introduction of the solidification medium, are in this instance simply allowed to remain in the solidified mass, and as in the case of the iron rods in Figure 1 are bent into hooks 8 at their upper ends, where they are I crete as a means of reinforcement is in itself known in the preparation of piles which are prepared in the foundation soil; there is, however, the particular advantage, when carrying out solidifying work, that the said tubes also serve to fasten the constructional part to the foundation soil. Further the tubes for the injection do not have to be pulled out after the solidification has been completed and do not have to be particularly cleaned or repaired. On the contrary the tubes remain in the structure serving as reinforcing iron.

We claim as our invention:

1. The process of connecting foundation soil to building structures which comprises inserting reinforcing members part-way into the soil, solidifying the soil, and erecting a structure on the solidified soil in attachment with the protruding portions of the reinforcing members.

2. The process of connecting foundation soil to building structures which comprises 7 inserting pipes part-way into the soil, introducing solidifying material into the soil through the pipes, and erecting a structure on the solidified soil in attachment with the pipes. I

3. A structure comprising in combination, artificially solidified foundation soil, the soil having embedded in it pipes through which solidifying material has been introduced into the soil, said pipes having hooked portions projecting beyond the soil, and a building structure connected to said hooked portions.

In testimony whereof we aflix our signa- WILLY SICHARDT. CARL ZEMLIN.
