Abstract
The utility model relates to a one-hole dual-purpose tunnel drain hole structure. The utility model aims at providing a one-hole dual-purpose tunnel drain hole structure which has the advantages that the cost is saved, the construction is convenient and the damage to the concrete structure is reduced. The technical scheme provided by the utility model is as follows: the one-hole dual-purpose tunnel drain hole structure is provided with an arched tunnel, wherein a layer of structural concrete is built on the inner wall of the tunnel; consolidation grouting holes are uniformly arranged on the top part, the bottom part and the two sides of the structural concrete; and the consolidation grouting holes comprise embedded pipes embedded in the structural concrete and drilling holes drilled in the rock body in the coaxial line with the embedded pipes. The one-hole dual-purpose tunnel drain hole structure is characterized in that: drain pipes are arranged in the drilling holes and communicated with the embedded pipes in a butt joint manner. The one-hole dual-purpose tunnel drain hole structure is applicable to tunnel design and construction according to drainage request in engineering construction.
Description
Technical field
The utility model relates to a kind of tunnel drainage hole structure, the tunnel drainage hole structure that an especially a kind of hole is dual-purpose.Be applicable to tunnel design, construction that drainage requirement is arranged in the engineering construction.
Background technology
In the tunnel that drainage requirement is arranged was built, drain hole often was provided with separately, also often is drilled with or arranges pre-buried pipe during construction separately; And this type of tunnel all need carry out backfill grouting, consolidation grouting etc. in order to guarantee Stability Analysis of Structures; Therefore, different types of repeatedly pipe laying, boring need be carried out in the barrel position, and pipe laying and borehole engineering amount are very big; Not only influence construction speed, and the integrality of concrete structure is had influence in various degree.
Summary of the invention
The technical problem that the utility model will solve is: the problem to above-mentioned existence, and provide a hole dual-purpose tunnel drainage hole structure, practice thrift cost, make construction convenient more, reduce destruction to concrete structure.
The technical scheme that the utility model adopted is: the tunnel drainage hole structure that an a kind of hole is dual-purpose; Tunnel with arched door type; The tunnel inwall is built has one deck structural concrete; Top, bottom and both sides at structural concrete all are provided with the consolidation grouting hole, said consolidation grouting hole comprise pre-buried in structural concrete pre-buried pipe and with the boring of injection in rock mass of pre-buried pipe coaxial line, it is characterized in that: in boring, fix a drainpipe and be docked and connected with pre-buried pipe.
Said consolidation grouting hole comprises that one group is positioned at dome portions and is radial arrangement, one group and is positioned at the vertical downward layout of tunnel floor and two groups and is positioned at the tunnel both sides respectively and is horizontal arrangement.
The beneficial effect of the utility model is: the position of drain hole is identical with the position in consolidation grouting hole in the utility model; The degree of depth of drain hole can be provided with according to design demand, adopts can to reduce the construction works amount behind this programme and to the influence of the integrality of concrete structure.In the tunnel of structural reinforcement complicacy, this programme has significantly reduced the pre-buried pipe of drain hole, has reduced and repeated the damage of different parts boring to structural concrete, for the setting of tunnel drain hole provides a kind of new thinking.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, present embodiment comprises arched door type tunnel, and one deck structural concrete 1 of tunnel inwall lining cutting, wherein is embedded with some pre-buried pipe 2-1 in the structural concrete 1.The deployment scenarios of pre-buried pipe 2-1 in structural concrete 1 is following in this example: the arch crown part at structural concrete 1 is radial arrangement, and left and right both sides are horizontal arrangement, and is then vertical downwards at tunnel floor.Injection has the boring with pre-buried pipe 2-1 coaxial line on the rock mass of tunnel, boring with constituted consolidation grouting hole 2 after corresponding pre-buried pipe 2-1 docks.After the said structure construction is accomplished, carry out the consolidation grouting construction.Be full of grouting agent in the consolidation grouting hole 2 behind the grouting construction; Can not serve as drain hole uses; Select part or all of consolidation grouting hole 2 (selecting) that it is carried out cleaning bottom of hole operation (degree of depth should satisfy the designing and arranging water hole and require) according to actual requirement of engineering; And the gutter 2-2 that installation is communicated with pre-buried pipe 2-1 at former boring position, pre-buried pipe 2-1 and gutter 2-2 have constituted the drain hole of tunnel jointly.The main feature of present embodiment is that drain hole is consistent with position, 2 hole, consolidation grouting hole, does not need other injection drain hole.
The main construction method of present embodiment is following: at first carry out the construction of the structural concrete 1 of tunnel inwall, carry out the pre-buried pipe 2-1 construction (being part within the structural concrete 1) in consolidation grouting hole 2 simultaneously; After structural concrete 1 construction is accomplished and reached certain length of time, carry out the drilling construction (being part outside the structural concrete 1) and the consolidation grouting construction in consolidation grouting hole 2 at pre-buried pipe correspondence position; The position of drain hole is consistent with position, 2 hole, consolidation grouting hole, after consolidation grouting construction is accomplished and reached certain length of time, cleaning bottom of hole to the designing and arranging water hole degree of depth is carried out in consolidation grouting hole 2, the 2-2 that fixes a drainpipe, and with it as drain hole.
Claims (2)
