Mutually it is welded to form.
Further limit, reinforcement net is also embedded with the pervious bed.
Further limit, the permeable thickness 20cm-30cm.
Using the utility model of above-mentioned technical proposal, the back-up coat structural support overall as tunnel, the whole of tunnel is improved
Body structural strength；Pervious bed can use foam concrete to pour and form, and foam concrete has internal porous due to itself
Structure, it is easy to groundwater seepage, pervious bed is by vault part and the packet of arch bottom into the underground water that vault part is penetrated into can edge
Arc-shaped curved surface infiltration downwards is final to come together in arch bottom point, and arch is embedded with the draining being made up of skeleton and surface layer fabric in bottom point
In pipeline, surface layer fabric is made using the good asbestos cloth of anticorrosion ability or glass fabric, is advantageous to groundwater seepage, draining
It pipeline inner hollow, can also facilitate underground water discharge, improve drainage effect；Skeleton is by some arc ribs and lengthways of rod phase
Mutually it is composed of a fixed connection, forms the upward arcuate channels of a curved surface, is advantageous to the pressure of scattered top, prevents drainage pipeline from existing
In work progress, compressive deformation, its structural strength is improved；Vault internal partial wall is provided with waterproof layer, and waterproof layer is by some splash guards
Unit is welded to each other composition, and waterproof Slab element can use PVC plastic flitch, and it can mutually be spliced by the way of hot melt；Thoroughly
Pre-buried reinforcement net in water layer, improve the structural strength of pervious bed；
Above-mentioned technical proposal uses following construction procedure：
First, premeasuring：
Tunnel section radius are predefined using equipment, and mark the section radius position；
2nd, back-up coat is constructed：
1st, drill：The uniformly drilling at 20cm-30cm outside the tunnel radial location of mark using rig；
2nd, it is in the milk：By grouting equipment by concrete grout hand-hole；
3rd, solidify：Concrete grout can be permeated after pouring into along fabric, by fabric in process of osmosis
Rock, sandy soil bond the back-up coat to form an arch；
3rd, tunnel piercing：
Usage mining machinery carries out longitudinal driving, and tunnelling footage, which is no more than, reinforces layer depth 30cm；Construction radius is not more than
Back-up coat inwall 10cm；
3rd, pervious bed is constructed：
1st, prefabricated reinforcement net is implanted into back-up coat inwall, expansion bolt is hammered into back-up coat inwall, by reinforcement net
It is fixed on expansion bolt；
2nd, drainage pipeline is laid, some drainage pipelines are laid side by side, adjacent spaces 20-25cm；
3rd, the foam concrete matched injection is carried out by grouting equipment encircleing bottom point pouring；
4th, vault part pouring is carried out when encircleing bottom point and reaching technological requirement intensity 65%-70%；
5th, when vault part reaches technological requirement 80%, powder is carried out to vault internal partial wall using water-proof acrylic acid paint
Brush；
4th, construction of waterproof layer：
PVC plastic flitch is fixed by swell fixture and waterproof layer, hot melt is used between adjacent two PVC plastic flitch
Bonding.
The utility model is compared with prior art, simple and reasonable, drainage effect is good.
