Description

Row of undercut piping lane tunnel, waterproof composite construction

Technical Field

The utility model relates to a row of underground concrete building structure, waterproof engineering, in particular to row of undercut piping lane tunnel, waterproof composite construction.

Background

At present, many culverts, tunnels, utility tunnel and cable trench etc. have designed and have adopted the undercut construction because ground space can not directly excavate. Namely, a lining is made on the side wall of the main hole; after the first lining construction is finished, a leveling layer is made, then a waterproof layer is paved, and then a main body of the structure (a second lining) is poured.

The lining is used as a temporary lining, which is a strong emergency support measure quickly implemented after excavation and is used for preventing and controlling the loosening of surrounding rocks. The first lining uses steel arch support as main bearing structure, and the concrete filled between the steel arches is auxiliary structure, so that its compactness is low, and it has no water-resisting function.

The drawbacks of this structure are: first, when meetting aquifer or high-pressure water layer, have a large amount of pondings in the cavern, ponding is difficult to discharge, can cause the construction degree of difficulty to increase, and the progress slows down. Secondly, when meetting aquifer or high-pressure water layer, can cause waterproof material to bulge or waterproof layer overlap joint fracture, lead to the waterproof layer to become invalid, the structural subject infiltration after appearing constructing. And thirdly, the waterproof layer fails, so that water seeped out of the waterproof layer enters the structural body, the structural body which is just poured has a diluting effect, and the strength of concrete is reduced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a row of undercut piping lane tunnel, waterproof composite construction.

In order to achieve the above object, the utility model discloses a row of undercut piping lane tunnel, waterproof composite construction, include: a hole body is arranged in the soil body, a lining and a structure main body are arranged in the hole body at intervals, and a row waterproof composite structure is arranged between the lining and the structure main body;

the row, waterproof composite structure include: a drainage plate is fixed on the inner wall of a liner through an anchoring piece; a macromolecule reaction adhesive type waterproof material is arranged between the drainage plate and the structure main body; and a drainage ditch connected with the water collecting well is arranged on the bottom plate part of the inner lining wall, and the bottom of the drainage plate is connected with the drainage ditch so as to drain the seepage water into the water collecting well.

Furthermore, a sealant layer is arranged on the fixing point of the anchoring piece.

Furthermore, the drainage plate comprises a bottom plate, and a plurality of convex parts and a plurality of drainage grooves which are arranged on the bottom plate, wherein the convex parts and the drainage grooves are alternately connected; the convex surface of the convex part faces a liner.

The utility model discloses a row, waterproof composite construction utilize bulge and the drainage recess of alternate connection on the drain bar, dredge the ponding well through the escape canal groove with the water that a lining oozes, and water can discharge the ponding well along the drainage recess under the effect of gravity, makes the hole indoor keep dry, clean, ensures the quality of water-proof effects and structure main part (two linings) construction. And row, waterproof composite construction need not carry out a lining and make level, has saved manual work and material cost, and row, waterproof composite construction installs conveniently simultaneously, can carry out the main structure construction after the installation is accomplished, has saved the total engineering time of undercut engineering greatly.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As the utility model discloses an undercut piping lane tunnel arrange, a waterproof composite construction's an embodiment, include: a hole body 6 is arranged in a soil body, a liner 1 and a structural main body 3 are arranged in the hole body at intervals, and a row and waterproof composite structure 2 is arranged between the liner and the structural main body;

the row, waterproof composite structure include: a drainage plate 21 is fixed on the inner wall of a liner through an anchoring piece; the drainage plate drains the leakage water of a lining to the water collecting well through the drainage channel. A polymer reaction paste type waterproof material (coil) 22 is provided between the drain board and the structural body.
