Description
Technical field
The present invention relates to a kind of basement guarded drainage construction method, specially a kind of hills rich water area basement near a river is anti-
Drainage and construction method.
Background technology
For basement floor, guarded drainage is emphasis.The guarded drainage way of traditional basement is nearby done along shear wall
Gutter, building way is towards the slope in gutter 0.5% on floor, 0.5% slope in ditch.
For the ease of statement, monolayer area is more than 20,000 square meters, basement definition of the length and width more than 150 meters by applicant
For " wide region basement ".
For wide region basement, if pressing traditional draining way, slope height is up to 75m × 0.5%=
37.5cm, but the building finished surface general thickness of basement only has 10-30cm, it will be than having built by traditional basement slope way
It wants high at face, leads to not implement.
And the water pressure that the building positioned at hills rich water area near a river is born is larger, it is impossible to keep perfect sealing again
Effect.Even if can control in the error range that specification allows, generation that also can be more or less is seeped water phenomenon, even if as far as possible
Using the processing of the methods such as closure, infiltration also can still exist on a small quantity in a certain range, so that influencing the normal use work(of building
Can, and mending-leakage, rehabilitation expense are also larger.
Invention content

Present invention is particularly suitable for the drainage constructions of hills rich water area near a river " wide region basement ", that is to say, that underground
The monolayer area of room is more than 20,000 square meters, and length and width are more than 150 meters.
It is the detailed description that " wide region basement " carries out drainage construction using this method below.For the ease of stating, with
It is lower to be referred to as " wide region basement " " basement ".
The bottom that can be seen that basement in conjunction with Fig. 1 to Fig. 3 is concrete structure bottom plate 5, open drain MG, draining
Underdrain AG and water draining plate 2 may be contained within the upper surface of concrete structure bottom plate 5, the paving of water draining plate 2 to seugh groove width
Edge.
For remote shearing wall zone, an open drain, open drain and sump is arranged every about 30 meters in the present embodiment
A sump 13 is arranged every about 30 meters with 0.5% slope to sump in the bottom of trench of connection, open drain.Pouring coagulation
The processing at sump position is paid attention to when soil structure bottom plate.
The width of the present embodiment open drain is 400mm, and the both sides of open drain are concrete structure furrow bank 1.
Plastering processing is carried out to furrow bank and bottom of trench after the bottom of trench both sides inner corner trim full coat JS coating 9 of open drain, face 10 of plastering
Thickness be 15mm or so, when plastering, pays attention to bottom of trench slope.Ditch grade is preferably 0.5%-1%, and the present embodiment chooses ditch base slope
Degree is 0.5%.
After the completion of plastering face 10, angle steel 11 is fixed on the inside of the upper surface of both sides furrow bank 1, and casting is laid between the angle steel of both sides
Iron runner cover plate 12.
According to the practical situation of each functional area of basement, seugh is set in the side of open drain or both sides,
Relatively high functional area is required aridity, seugh is respectively provided in the both sides of open drain, as electrical equipment room is arranged
Functional area etc..Fig. 1 is shown in the side of open drain MG setting seugh AG.
The width of the present embodiment seugh is 500mm, and the side furrow bank of remote shear wall area sewerage underdrain shares draining
The furrow bank of bright ditch, other side furrow bank are built by laying bricks or stones with the shale hollow brick 3 of long * high * wide=240*140*90.
It can be seen that before seugh is built by laying bricks or stones from structure shown in FIG. 1, need first to lay water draining plate 2, water draining plate paving
To the edge of seugh groove width.The material of the present embodiment water draining plate is HDPE, selects its plate thickness for 30mm, wall thickness is
1.7mm。
After water draining plate 2 is laid, it is laid with non-woven fabrics 4, when preparing non-woven fabrics, width dimensions are seugh groove
The double-width+height of shale hollow brick+of width+shale hollow brick spreads the width in groove, and the present embodiment is by non-woven fabrics
It spreads the width in groove and is set as about 150mm, so the overall width of non-woven fabrics is about 1000mm.Non-woven fabrics 4 is by water draining plate 2
Lateral margin upper surface covers.
When shale hollow brick 3 is built by laying bricks or stones, width direction bottom surface is pressed on non-woven fabrics 4.After shale hollow brick is laid, arranging
Middle sand 8 (fineness modulus 3.0-2.3, average grain diameter 0.5-0.35mm) is filled up in the groove of water underdrain, makes the top surface of middle sand 8
It is concordant with the upper surface of shale hollow brick 3, then by the non-woven fabrics of laying 4 successively by the outside of shale hollow brick 3, upper surface and
It wraps up the top surface of middle sand 8.
After non-woven fabrics 4 wraps, light-weight aggregate face layer 6 is poured above water draining plate 2 and seugh, light-weight aggregate face layer 6
Upper surface is concordant with the upper surface of open drain both sides furrow bank.When light-weight aggregate face layer pours, pay attention to the non-woven fabrics of middle sand top surface
It washes and presses.
At nearly shear wall, open drain MG and seugh AG and shear wall JLQ are arranged in parallel, and seugh is located at
The remote shear wall side of open drain, in addition adds narrow slot ZC relatively narrow together also between open drain and shear wall, and draining is bright
The distance between ditch and shear wall buttress outside are small as possible, and the both ends of narrow slot ZC terminate in the buttress FBZ of shear wall.Narrow slot and
Open drain is constructed simultaneously, and JS coating and plastering processing are identical as open drain.
Finally pour building coats 7.The building coats of the present embodiment is pea gravel concreten face layer, pea gravel concreten face layer
Upper surface is concordant with 11 upper edge of angle steel of open drain both sides.When building coats pours, open drain side or both sides about 5m
The building coats in region preferably has the water guide gradient of 0.5%-1%, the present embodiment to use 0.5% slope with respect to open drain respectively
Degree.When pouring building coats 7 between the nearly shear wall side of groove and shear wall of open drain at nearly shear wall, in narrow slot and draining
Pre-buried drainpipe 14 between bright ditch makes the water that narrow slot is collected be introduced into open drain.The present embodiment is using pvc pipes as draining
Pipe, nominal outside diameter preferably select 110mm.
Once shear wall has water leakage, infiltration is introduced by drainpipe in open drain after being collected by narrow slot ZC, together
When shear wall infiltration region can rapidly be made by plasterboard SGB etc. and block processing at narrow slot ZC, recovery sensory effects wait for
Professional waterproof operating personnel repairs its shear wall after showing up, and avoids underground chamber interior environment moist.
