The utility model discloses a pipe gallery structure thoroughly cancels the fertile groove of foundation ditch both sides and the vertical stack of pipe gallery and arranges, effectively utilizes underground space, solves narrow and small space and builds the difficult problem of utility tunnel, and effectual reduction earthwork excavation and backfill volume shorten construction period, reduce the potential safety hazard of foundation ditch.
Description
The technical field is as follows:
The utility model belongs to the technical field of utility tunnel structure, concretely relates to double-deck piping lane structure of fertile groove of no.
Background art:
The demand for utilities in the rapid development of cities is increasing with the economic growth and the enlargement of the urban scale, and the development of underground space resources is also being taken into consideration. The construction of urban utility tunnel often reduces the occupation of underground space by compressing the pipe gallery construction space, which will be the trend of the construction of subsequent urban utility tunnels. The fertilizer groove of both sides leads to the low-usage in soil when building utility tunnel, consequently how to guarantee to accomplish the problem that utility tunnel built under the condition of corridor pipeline demand in narrow and small space and await solution urgently.
The utility model has the following contents:
the utility model provides a do not have double-deck pipe gallery structure in fertile groove, guarantee to go into the building that realizes utility tunnel under the condition of corridor pipeline demand in the narrow and small space, increase the rate of utilization in soil.
The utility model provides a technical problem's technical scheme as follows:
A double-layer pipe gallery structure without a fertilizer groove comprises fender posts and a pipe gallery structure body, wherein the fender posts are symmetrically fixed on two sides of a foundation pit, a net hanging guniting layer, a leveling layer and a waterproof layer are sequentially paved on the outer surface of the inner side of each fender post from inside to outside, and the leveling layer is positioned between the net hanging guniting layer and the waterproof layer; the pipe gallery structure body is provided with the bilayer, and it sets gradually in the foundation ditch middle department, every layer by supreme down the pipe gallery structure body includes bottom plate, medium plate and roof.
Further, the net hanging guniting layer adopts C20 anchor shotcrete.
Furthermore, the leveling layer is made of cement mortar, and the ratio of cement to sand of the cement mortar is 1: 2.5-3.
Furthermore, the waterproof layer adopts self-adhesive polymer modified asphalt waterproof coiled material.
Furthermore, the height of the net hanging guniting layer, the height of the leveling layer and the height of the waterproof layer are consistent, and the thicknesses of the net hanging guniting layer, the height of the leveling layer and the height of the waterproof layer are reduced in sequence.
Furthermore, the height of the net hanging guniting layer, the height of the leveling layer and the height of the waterproof layer are all smaller than the height of the fender post.
Compared with the prior art, the utility model following beneficial effect has: the utility model discloses a pipe gallery structure thoroughly cancels the fertile groove of foundation ditch both sides and the vertical stack of pipe gallery and arranges, effectively utilizes underground space, solves narrow and small space and builds the difficult problem of utility tunnel, and effectual reduction earthwork excavation and backfill volume shorten construction period, reduce the potential safety hazard of foundation ditch.
Drawings
The invention will be further explained with reference to the drawings and the detailed description below:
fig. 1 is the structural schematic diagram of the fertilizer groove-free double-layer pipe gallery structure of the utility model.
The numbers in the figures are as follows: 1-a tube corridor structure body; 2-hanging a net and spraying a slurry layer; 3-leveling layer; 4-waterproof layer; and 5-fender pile.
Detailed Description
Example 1
As shown in fig. 1, a double-deck piping lane structure of no fat groove, including fender pile 5 and piping lane structure body 1, fender pile 5 is provided with two, and its symmetry is fixed in the foundation ditch both sides, and 5 inboard surfaces of every fender pile have laid hanging net whitewashing layer 2, screed-coat 3 and waterproof layer 4 from inside to outside in proper order, screed-coat 3 is located hanging net whitewashing layer 2 with between the waterproof layer 4. The net hanging guniting layer 2 adopts C20 anchor shotcrete, and the net hanging guniting layer 2 comprises a steel bar hanging net and shotcrete and is used for preventing soil body collapse in the construction process; the leveling layer 3 adopts cement mortar, and the ratio of cement to sand of the cement mortar is 1:2.5, so that the construction level can be quickly reached; and the waterproof layer 4 is a self-adhesive polymer modified asphalt waterproof coiled material. The height of the net hanging guniting layer 2, the height of the leveling layer 3 and the height of the waterproof layer 4 are consistent, but are all smaller than the height of the fender post 5, and the thicknesses of the three layers are reduced in sequence. Pipe gallery structure body 1 is provided with two-layerly, and it sets gradually in the foundation ditch middle department, every layer by supreme down pipe gallery structure body 1 includes bottom plate, medium plate and roof.
The utility model provides a double-deck piping lane structure's work progress as follows: 1) slope is set and a foundation pit is excavated; 2) symmetrically driving guard piles into two sides of the foundation pit; 3) carrying out net hanging guniting construction on the inner side surface of each fender post to form a net hanging guniting layer; 4) leveling construction is carried out on the surface of the suspended net guniting layer to form a leveling layer; 5) performing waterproof construction on the surface of the leveling layer to form a waterproof layer; 6) with bottom plate, medium plate and the roof of piping lane by supreme placing down and form piping lane structure body 1 in the foundation ditch, then pour the fixed double-deck piping lane structure that forms of concrete.
this double-deck pipe gallery structure thoroughly cancels the fertile groove and the vertical stack of pipe gallery of foundation ditch both sides and arranges, effectively utilizes underground space, solves the difficult problem of narrow and small space construction utility tunnel, and effectual reduction earthwork excavation and backfill volume shorten construction period, reduce the potential safety hazard of foundation ditch.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
