Abstract
The utility model relates to a kind of facing wall walls to carry on the back drain structure, including, it is mounted on the polyvinylchloride splash guard of wall back；Water draining beak, positioned at the center of polyvinylchloride splash guard；Loaded filter is set between the polyvinylchloride splash guard and water draining beak；Drain hole is connected with the water draining beak.After rainwater, crevice water of seepage flow etc. meet splash guard in the massif of wall behind, downward fair current to loaded filter is flow in drain hole by Central Drainage mouth through loaded filter, is finally drained to outside wall by drain hole.The wall behind soil body is isolated with wall by the drainage systems of larger area for the utility model, collects wall back seepage through soil mass water, and concentration is drained in drain hole, is finally discharged outside facing wall by drain hole, improves the stability and durability of facing wall.
Description
Technical field
The utility model relates to highway engineering technical fields, carry on the back drain structure in particular to a kind of facing wall wall.
Background technique
In the excavations such as highway, Class I highway section, facing wall is upper side slope using more protection form, Er Qieduo
It is entity facing wall, is mostly built by mortar flag stone.Since wall back is mostly loose soil bed, fragmented rock body, therefore there is water after rainwater weather
Stream from wall behind seepage flow, wash away, cause facing wall deformation, sliding after penetrating into wall, can develop when serious as total collapse, sternly
Ghost image rings the operation and traffic safety of highway.Traditional design scheme is wall setting drain hole behind, aperture rubble and geotechnique
Loaded filter is arranged in cloth, but such scheme and wall back soil body contact area are limited, only can have water infiltration in the subrange of aperture end
Out, drainage effect is extremely limited.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of facing wall wall back drain structure, pass through larger area
Drainage systems the wall behind soil body is isolated with wall, collect wall back seepage through soil mass water, concentration be drained in drain hole, finally
Outside by drain hole discharge facing wall, the stability and durability of facing wall are improved.
The utility model solves technical solution used by its technical problem are as follows:
A kind of facing wall wall back drain structure, including, it is mounted on the polyvinylchloride splash guard of wall back；Water draining beak, position
In the center of polyvinylchloride splash guard；Loaded filter is set between the polyvinylchloride splash guard and water draining beak；It sluices
Hole is connected with the water draining beak.After rainwater, crevice water of seepage flow etc. meet splash guard in the massif of wall behind, downward fair current to anti-filter
Layer, is flow in drain hole by Central Drainage mouth through loaded filter, is finally drained to outside wall by drain hole.
Preferably, the polyvinylchloride splash guard covering wall carries on the back gamut, the square for being 2m in side length.
Preferably, the water draining beak is located at the center of the square polyvinylchloride splash guard, and water draining beak diameter is
5cm, length are not less than 10cm.
Preferably, the loaded filter includes anti-filter rubble and anti-seepage geotextile.
Preferably, the water draining beak is directly protruding into the drain hole.
Preferably, the drain hole is connected with the water draining beak by pipeline or channel.
Splash guard must overlap securely after wall, and seam is tight, closely touch the soil body or rock mass after wall, and when installation prevents from rupturing.
When building facing wall or retaining wall, wall back is laid with polyvinyl chloride splash guard, can effectively after barrier wall seepage flow rainwater to facing wall
Infiltration infiltration, prevent deformation of wall, sliding, can solve infiltration caused by wall body structure damage.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is the utility model wall back drain structure scheme of installation；
Fig. 2 is splash guard plan view；
Fig. 3 is splash guard sectional view.
Component, toponym and corresponding label are shown in figure:
Rock mass or the soil body 1, polyvinyl chloride splash guard 2, anti-filter rubble 3, anti-seepage geotextile 4, water draining beak 5, drain hole after wall
6, mortar flag stone facing wall 7.
Specific embodiment
The present invention will be further described with example with reference to the accompanying drawing.
Referring to Fig.1, the water drainage behind the wall construction of the utility model, comprising: carry on the back range in the entire wall of mortar flag stone facing wall 7
It is interior, it is laid with the polyvinyl chloride splash guard 2 containing Central Drainage mouth, seepage water in the former natural rock-filled or rock mass of wall behind is split
Gap water meet polyvinyl chloride splash guard 2 after seepage flow it is downward, after the loaded filter being made of anti-filter rubble 3 and anti-seepage geotextile 4 from
Central Drainage mouth 5 is drained to drain hole 6, is ultimately discharged into outside wall.
Water drainage behind the wall plate must be close to former natural rock-filled or rock mass, and overlap joint securely, and must be covered pressure layer by upper layer from top to bottom,
The lap of splice is not less than 10cm.It must be provided with loaded filter around Central Drainage mouth, water draining beak blocked with sediment prevention etc..Water draining beak
Diameter is 5cm, and length is not less than 10cm, and guarantee is protruded into drain hole, or is connected by pipeline and channel with drain hole.It builds
It to put down building stones when facing wall gently, forbid throwing, to prevent breaking splash guard.
When construction, firstly, determining the size of drain bar according to the slope surface gradient, length；Second step, when building facing wall,
Wall back is laid with polyvinyl chloride drain bar, and when masonry must prevent from destroying splash guard.Third step, when installation is to sluicing hole site, first
Drain hole security protection is secured, and the gradient is outside, at this time docks the Central Drainage mouth of drain bar well with drain hole；4th step,
Loaded filter is laid with around water draining beak；5th step continues up masonry facing wall, installs splash guard above.
Engineering practice shows the facing wall for creating or repairing, and polyvinyl chloride splash guard is arranged after wall, and wall is native behind
Body is isolated with facing wall, leads to water in the soil body outside wall through water draining beak along splash guard, and soil body infiltration, ponding are to wall after can solving wall
The destruction of body.
Be explained in detail above in conjunction with example of the attached drawing to the utility model, but the utility model be not limited to it is above-mentioned
Example within the knowledge of a person skilled in the art can also be before not departing from the utility model aims
The various change made is put, also should be regarded as the protection scope of the utility model.
