Description
Technical field
The utility model relates to cover the combined water proof drainage system of underground structure in permeable stratum in one kind, belong to ground
The water-proof drainage systems technology field of lower structures.
Background technique
The underground engineering construction phase mainly guarantees normal construction condition by the measure of foundation pit Yield rainfall relation, and the runtime relies primarily on
Concrete self-waterproof ability simultaneously cooperates and solves the problems, such as concrete anti-seepage using measures such as waterproof roll, water-repellent paints, is tied by underground
Structure exterior wall undertakes external whole soil water pressures.
For underground structures such as ultra-deep subway station, basements, when underground water buried depth is shallower, stratum water penetration is stronger
When, the construction time may face foundation pit water percolating capacity it is larger, take out effluent cost it is higher, run-time structure exterior wall will bear larger outer hydraulic pressure
Power and the problems such as be easy to happen infiltration, and then influence normal use, threaten main structure body quality and safety.
Utility model content
The technical problem to be solved by the utility model is to provide the combinations that underground structure in permeable stratum is covered in one kind
Formula water-proof drainage system can reduce ultra-deep underground structure exterior wall external water pressure, reduce structure infiltration risk, while reducing and applying
Duration foundation pit water percolating capacity.
To solve above-mentioned technical problem the technical scheme adopted by the utility model is on cover underground in permeable stratum and construct
The combined water proof drainage system of object, including underground structure, the stratum on the outside of underground structure successively include saturating from top to bottom
Water stratum and opposite impervious stratum, the structure outer lateral surface of underground structure and plate outer side face are provided with waterproof roll,
Foundation pit enclosure structure is equipped on the outside of the structure outer of underground structure, foundation pit enclosure structure top is far from underground structure knot
The side of structure exterior wall is provided with impervious body, and bottom end insertion velatively waterproof layer, top and the underground structure outside of impervious body are tightly
The wall of contiguity touching or insertion underground structure.
Further, the structure outer of underground structure be provided between waterproof roll and foundation pit enclosure structure it is permeable
Loaded filter, the structure outer bottom of underground structure are provided with the permeable loaded filter of connection and underground structure internal drainage structure
Drainage hole.
Further, permeable loaded filter is filled using sandy gravel class dank material.
Further, the structure outer of underground structure is obliquely installed drainage hole, and outside underground structure structure
The lateral ends of wall are eminence end, inner opposite end is lower end, can draw underground water.
Further, being equipped with catch basin on bottom plate inside underground structure for drainage hole, infiltration can be led to collection
Concentrate pump drainage in puddle.
Further, impervious body is cut-pff wall, high-pressure rotary jet grouting pile or steel sheet pile.
The beneficial effects of the utility model are: covering permeable stratum penetrating passage in partition, reduction is applied by setting impervious body
Duration and runtime take out effluent cost.By the way that permeable loaded filter and drainage hole is arranged, guidance percolating water discharge avoids underground from constructing
Object bears larger water pressure, while the soil pressure that will act on foundation pit enclosure structure passes to subterranean by permeable loaded filter
Object is built, under permanent operating condition, underground structure and foundation pit enclosure structure shared soil pressure can be made, guarantees structure safety.
Detailed description of the invention
Fig. 1 is the cross-sectional structural schematic diagram of the utility model；
Marked in the figure: 1- underground structure, 2- waterproof roll, 3- permeable stratum, 4- are enclosed with respect to impervious stratum, 5- foundation pit
Protection structure, 6- impervious body, the permeable loaded filter of 7-, 8- drainage hole, the ground 9- high level, 10- are with respect to impervious stratum crest level.
Specific embodiment
For ease of understanding with implementation the utility model, the preferred embodiment combination attached drawing work of anthology utility model is furtherly
It is bright.
As shown in Figure 1, the utility model includes underground structure 1, the stratum in 1 outside of underground structure is from top to bottom successively
Including permeable stratum 3 and opposite impervious stratum 4, the structure outer lateral surface of underground structure 1 and plate outer side face are provided with
Waterproof roll 2, the structure outer outside of underground structure 1 are equipped with foundation pit enclosure structure 5, and 5 top of foundation pit enclosure structure is remote
Side from 1 structure outer of underground structure is provided with impervious body 6, the bottom end insertion velatively waterproof layer of impervious body 6, top with
The wall of underground structure 1 is in close contact or is embedded on the outside of underground structure 1.Impervious body 6 can be cut-pff wall, high-pressure rotary jet grouting pile
Or the stop waters measure such as steel sheet pile, permeable stratum penetrating passage is covered by the way that impervious body 6 is arranged, in partition, reduce the construction time and
Runtime takes out effluent cost.
When implementing, the generally vertical setting of impervious body 6, when the structure outer of underground structure 1 has traversing section, impervious body
6 bottom end is embedded in velatively waterproof layer, top is directly embedded into 1 wall of underground structure, embodiment as shown in Figure 1.When
When impervious body 6 needs to be embedded in the situation of structure outer vertical section of underground structure 1, L can be set by the top of impervious body 6
Type structure.
The structure outer of underground structure 1 is provided with permeable loaded filter 7 between waterproof roll 2 and foundation pit enclosure structure 5,
The structure outer bottom of underground structure 1 is provided with the draining for being connected to permeable loaded filter 7 and 1 internal drainage structure of underground structure
Hole 8.Permeable loaded filter 7 can be used sandy gravel class dank material and fill.Drainage hole 8 is preferably obliquely installed, and
The lateral ends of 1 structure outer of underground structure are eminence end, inner opposite end is lower end.By the way that permeable 7 He of loaded filter is arranged
Drainage hole 8, guidance percolating water discharge, avoids underground structure 1 from bearing larger water pressure, while will act at foundation pit enclosure structure
Soil pressure on 5 passes to underground structure 1 by permeable loaded filter 7, under permanent operating condition, can make underground structure 1 and base
5 shared soil pressure of pit enclosure structure guarantees structure safety.
For convenience of draining, it is equipped with catch basin for drainage hole 8 on bottom plate inside underground structure 1, infiltration can be led to
Catch pit concentrates pump drainage.
