Abstract
The utility model discloses a box type foundation submarine tunnel structural component, which is formed by a box type foundation inserted in the seabed soil and the tunnel above the seabed soil, the box type foundation is a bottomless rectangular box body, in which traverse and vertical separators are arranged, the top plate of the box is a flat or a concave arc shaped plate, each chamber on the top plate separated by the traverse and the vertical separators is provided with at least one switchable processing through hole; the tunnel over the box foundation is a tube body with a semi-circular or a semi elliptical cross section, a flat separator is arranged on the upper part of the tube body, the symmetric shaft in the tube body is provided with a vertical separator; the structural component of the utility model can be prefabricated on land, and the utility model can make air-floating transportation with a convenient assembling-in-site, a fast construction and a low construction expense, which can be applied to soft soil seabed foundation.
Description
Technical field
The utility model relates to a kind of box foundation seabed tunnel structural member.Belong to the building unit in road traffic and the ocean engineering field.
Background technology
At present, the seabed tunnel of having implemented in the engineering has two kinds of forms: a kind of is to have at the distance sea bottom surface that the borehole lining structure becomes seabed tunnel in the rock of certain depth or the soil body, and the seabed tunnel construction period of this kind form is long, difficulty of construction height, construction costs height; Another kind is the prefabricate syndeton that is arranged in sea bed top layer or shallow soil, as will be on land the box of prefabricated segmentation or cylinder type spare be placed on sea bed surface or shallow embedding in sea bed, then each segment structure spare is done the seabed tunnel that sealing is formed by connecting.For the seabed tunnel of a kind of form in back, in order to overcome buoyancy, a kind of method be with the tunnel structure section build very huge, come the balance buoyancy by construction weight, so just increased the engineering material expense; Another kind method is embedding in the seabed grooving, by construction weight with structurally bury native weight and come the balance buoyancy, has so just increased construction cost, and particularly in darker seabed grooving with to bury the construction cost that bankets high especially, the while also can extend the duration.
Summary of the invention
The purpose of this utility model is to provide a kind of box foundation seabed tunnel structural member, adopts this structural member to make up seabed tunnel and has easy construction, the characteristics that construction costs is relatively low.
For achieving the above object, the utility model is realized by following technical proposals: box foundation seabed tunnel structural member, form by the box foundation and the tunnel more than the seabed soil face that are inserted in the seabed soil, it is characterized in that, box foundation is the rectangular box at the following no end, orthogonal horizontal and vertical vertical clapboard is set in the casing, roof box is dull and stereotyped or to the arc of lower convexity, but the technology through hole of a switch is set in each the cabin lattice that is separated into by horizontal and vertical vertical clapboard on top board at least; Tunnel on the box foundation is that the cross section is semicircle or semielliptical cylindrical shell, and the top in the cylindrical shell is provided with one deck horizontal baffle, and the axis of symmetry place in the cylindrical shell is provided with vertical clapboard.
The horizontal and vertical vertical clapboard that is provided with in the above-mentioned casing respectively is 1 to 8, and the height of dividing plate is equal to or less than the height of external box wall.
Superiority of the present utility model is: box foundation seabed tunnel structural member can be prefabricated on land, can air supporting transport on the water, and on-the-spot easy for installation, construction speed is fast, and engineering cost is relatively low, is applicable to weak soil sea bed ground.
Description of drawings
Fig. 1 is a sectional schematic diagram of the present utility model.
Fig. 2 is the upward view of the box foundation among Fig. 1.
1 is the tunnel shell among the figure, and 2 is the box foundation tank wall, and 3 is the vertical vertical clapboard in the box foundation, 4 is box foundation top board and tunnel road surface, and 5 is the through hole on the box foundation top board, and 6 is the vertical clapboard in the tunnel, 7 is the horizontal baffle in the tunnel, and 8 is the horizontal vertical clapboard in the box foundation.
The specific embodiment
An embodiment is as follows for the utility model: as depicted in figs. 1 and 2, the box foundation of box foundation seabed tunnel structural member is a cuboid, the top board of casing is dull and stereotyped, be provided with 4 layers of vertical vertical clapboard and 4 layers of horizontal vertical clapboard in the casing, the height of middle vertical clapboard is identical with the height of external box wall, the height of other vertical clapboard is short in the height of external box wall, the top board in each lattice cabin is provided with through hole, the tunnel is semicircle cylindrical shell, two passages about being provided with 1 layer of vertical clapboard in the tunnel tunnel being divided into are provided with 1 floor horizontal baffle the tunnel are divided into carriage way district and pipeline district in the tunnel.
After the box foundation seabed tunnel structural member of segmentation is prefabricated on land, it is moved in water, in the casing that back-off is placed, inflate, structure air supporting floated transport to the erecting bed, install buoyancy tank or ship hang and locate after emit gas in the casing, make structural member sink down into bottom half and in the mud face, extract gas and water in the casing out by through hole then, utilize vacuum pressure that casing is inserted in the seabed soil, seal through hole at last.After being installed in multi-segment structure spare on the sea bed, the sealing that carries out seam connects to be handled, and drains the water in the tunnel afterwards, road surface pavement, pipeline, cable etc. in the tunnel.
The box foundation that is inserted in the soil body can overcome the horizontal applied force that subsea current produces the tunnel on the one hand, utilize the buoyancy that the soil body cohesion on the vertical clapboard and frictional force overcome the tunnel in tank wall and the case on the other hand, so just can make light-dutyer that tunnel structure does.
Claims (2)
1. box foundation seabed tunnel structural member, form by the box foundation and the tunnel more than the seabed soil face that are inserted in the seabed soil, it is characterized in that, box foundation is the rectangular box at the following no end, orthogonal horizontal and vertical vertical clapboard is set in the casing, roof box is dull and stereotyped or to the arc of lower convexity, but the technology through hole of a switch is set in each the cabin lattice that is separated into by horizontal and vertical vertical clapboard on top board at least; Tunnel on the box foundation is that the cross section is semicircle or semielliptical cylindrical shell, and the top in the cylindrical shell is provided with one deck horizontal baffle, and the axis of symmetry place in the cylindrical shell is provided with vertical clapboard.
2. according to the described a kind of box foundation seabed tunnel structural member of claim 1, it is characterized in that the horizontal and vertical vertical clapboard that is provided with in the above-mentioned casing respectively is 1 to 8, the height of dividing plate is equal to or less than the height of external box wall.
