HERBERT F. DUNHAM, OF NEYV YORK, N. Y.

TUNNEL-SECTION.

SPECIFICATION forming part of Letters Patent No. 736,507, dated August 18, 1903.

Original application filed September 11, 1900, Serial No. 29,626. Divided and this application filed August 9, 1902. Serial No. 119,020. (No model.)

To [I/ZZ whom it may concern.-

Be it known that I, HERBERT F. DUNl-IAM, a citizen of the United States, residing in the city of New York, in the county of New York and State of New York, have invented certhe high pressure in which the workmen are obliged to perform their labor if the carrying out of the operation requires their services under water, and if sections of the tunnel are to be laid the difficulty of dredging a proper place on the bed and keeping it clear till the section has been placed in position renders .such procedure not only unduly costly, but

the results unsatisfactory.

By my present invention, the subject of this application, which is a division of an application filed by me on September 11, 1900, hearing Serial No. 29,626, for method of constructing and laying subaqueous tunnels, it is made possible to lay a tunnel under water section by section and carry on the operation from a secure working platform above the surface of the water and to dredge, if necessary, the water-bed immediately beneath the section and to sink the section into the dredged channel as fast as the dredging proceeds. To this end sections are constructed upon the land, if desired, and launched upon the body of water and then towed to the point at which operations are in progress. Each section is provided with platform-holding means for receiving the stan chions or up rights for the working platform, which may be placed in position before the section is launched or while it is still floating upon the water. The sections are also provided with mating interlocking devices of such a character that the section while being sunk will interlock with a sunken section, and the interlocking devices will assure a tight joint between the sections and the accurate positioning and alinement thereof.

The most expeditious way of dredging for the reception of a body or structure is to work directly beneath it, and myimproved sections are so constructed that hydraulic or other forms of dredging may be carried on, removing the bed directly from under the section as it is being sunk. This form of structure permits the section to be sunk and maintained in the desired position. If the bed is uneven, the highest point will receive the entire Weightof the section,whereupon the operation of hydraulic dredging will be facilitated at that point, the interlocking devices and the stanchions, which may be slidingly connect ed, holding and guiding the section, so that one end will not sink faster than the other. The section may be suspended by the stanchions and proper derricks and the excavations thereunder filled with concrete or other suitable material. To prevent longitudinal strain upon the uncompleted tunnel, each section may be so constructed that it will engage securely the bed. Its engaging portion may, if desired, in practice be so formed that it will prevent the filling of the dredged excavation by shifting of the material of the bed.

Referring to the drawings accompanying and forming part of this specification, Figure l is a perspective view of a form of tunnelsection embodying my invention. Fig. 2 is an end view, Fig. 3 is a side view, Fig. 4 is a plan view, and Fig. 5 is an end view, of a form of section having a single passage-way.

The section, as shown, comprises a body portion (designated in ageneral way byA) and may be made of any suitable material. The section is shown as traversed by two passageways 6, with a partition or wall 7 therebetween. At convenient points on the section stanchion or platform supporting means may be provided-in the present instance sockets 8, located in wings or extensions 9 from the heads 10. The sockets are designed to receive stanchions for guiding and controlling the section as it is being sunk and for supporting a working platform from which subsequent sections may be supported and guided.

When the section is being sunk and nears its final position, it is well to augment the guiding influence of the stanchions and to positively interlock the sections. Suitable and convenient means for so doing are in the present instance shown in the form of dowels 11, projecting downwardly from extensions 12 from one of the heads 10. The other head is shown as provided with sockets 13 in extensions 14, projecting therefrom, for the reception of the dowels.

The units organized as illustrated herein are provided with faces 15 upon the extensions 12, which are in a plane coincidentwith the line of movement of the sections when properly sinking to their mating positions and which faces are adapted to embrace the sides or faces 16 upon the opposite head or end of a similarly-formed section and serve to guide and position the section, guiding it laterally and producing axial justification. The projections 12 are also provided upon their lower sides with faces 17, adapted to rest upon faces 18 of the extensions 14 to positively and accurately limit the descent of the section when it has reached its final position. The dowels 11 are shown in the present instance as square in cross-section and beveled on their free ends and the sockets also as square in cross-section. The beveling of the dowels will assist in their ready entrance into the sockets. The faces of the heads 10, constituting the meeting or abutting ends, are also 1 shown as matching to assist in guiding the sections to position and to make a flush and tight joint between the sections. Thus it will be seen that each section is provided with its own guiding means-to Wit, the dowels entering the sockets, the abutting ends of the section-heads constituting guiding-faces to guide the section to place, and also the lateral or side-embracing guiding-faces, which force the section to sink in a straight line,

. prevent axial rotation of the section, and remove strain from the dowels to a large extent.

.For providing convenient access to the bed beneath the section while it is in a position approaching its final position one or more openings (designated in a general way by B) may be constructed in the section and in the present instance are shown comprising tubular portions 19, and upon top of the section conical bosses 20 may be placed to provide flaring mouths 21 for the openings.

In Figs. 1 to 4 the openings are shown as located in the wall or partition dividing the passage-ways and in Fig. 5 as traversing the passage-way.

It is intended that the bed will be dredged through the openings as the section is being lowered and,if desired,pits or pockets dredged from beneath the section, which pits or pockets and the openings will be filled with hydraulic cement, concrete, or other suitable material and the tops and side of the tunnel be covered with similar material. The form shown in Fig. 5 will after the hardening of the filling-in material have removed therefrom the portion of the tubular opening 19 which is an obstruction to the passage-way 6.

For the purpose of preventing longitudinal movement of the tunnel during construction or afterward the section may be provided with retaining means, (designated in a general way by 0,) and in the present instance is shown as comprising a reinforced depending leaf 22, which leaf not only prevents lateral movement of the tunnel, but also keeps loose or shifting material from gaining access to the excavation beneath the section.

Each end of the passage-ways may before the section is launched be provided with removable bulkheads 23 for excluding water and rendering the section buoyant. These bulkheads will of course be removed at the proper time in the construction of the tunnel.

The section illustrated in Fig. 5 is for a single-passage-way tunnel-and that of the other figures the section is for a twin conduit or double-passage-way tunnel. Any number of conduits or passage-ways may be'provided, and the organization of the openings for reaching the bed beneath the section may be differently constituted as in practice may be necessary.

Although but one form of section has been shown herein, yet it will be apparent that such is for the purpose of illustration of the invention and that in practice many changes in details of construction may be had without departure from the spirit of my invention.
