Description
Technical field
A kind of pumping equipment is the utility model is related to, particularly a kind of highway bridge bridge deck drainage facility.
Background technology
Bridge is for road, pipeline etc. each other mutually across or across natural objects (such as water body, mountain valley)
Engineering structure, bridge are the piths in communications and transportation composition.With the development of science and technology, bridge construction also obtains
Rapidly development.Bridges in Our Country construction in recent years develops rapidly, and the ratio that bridge investment accounts for social capital construction investment is also more next
It is bigger.During bridge construction, the setting of bridge drainage system is highly important part during bridge construction
One of, it is related to the normal use of whole bridge.But designer's often heavier applying depending on bridge construction jackshaft girder construction
Work and design, and ignore the research to bridge drainage system.But bridge drainage system functional relationship bridge durability and traffic peace
Congruent problem, it is impossible to regard as unimportant.
Being currently known may cause science of bridge building to be damaged because the drainage system of bridge floor has problem.It is mainly manifested in
Following several respects：(1) long when the bridge floor rainwater holdup time, rainwater can first pass through pave-load layer and gradually permeate again under pave-load layer
Waterproof layer, finally enter inside bridge structure, the reinforcing bar in bridge spanning, bridge pier and bridge abutment structure may because infiltration become rust
Erosion, reinforcing bar toughness and intensity decreases, the stability of this service life and normal operation to bridge can all have adverse effect on.
(2) if the water entered by deck crack or seam etc. impenetrable waterproof layer inside bridge structure can not be discharged in time, at one section
Between after the bridge deck pavement internal void water capacity easily reach saturation.Vehicle can quickly make full in bridge deck pavement when bridge floor is walked
Flow velocity and pressure are produced with pore water, and then bridge deck pavement is produced peeling, loose, pit-hole etc..(3) if bridge floor
Water effectively, can not be excluded promptly, and moisture film even ponding will be formed in bridge floor；Bridge floor antiskid degradation will be made, work as vehicle
It is able to may occur to slide because of moisture film or ponding when driving through bridge floor or can not normal braking.Again because traveling can splash ponding
The sight of driver can be influenceed, makes the reduction of safety traffic coefficient, and one of inducement of multiple traffic accident on rainy day bridge.This
The rainwater of external storm period bridge floor excludes that if effect is bad deep water will be assembled so that traffic jam occurs, this also gives
Bridge, people, vehicle bring potential safety hazard.
People have started to pay attention to excluding bridge floor precipitation as quickly as possible at present, this depend on normal work all the time, effectively
Drainage system.It is but main on highway bridge bridge floor at present that ponding is carried out using the structure for excavating rhone or drainage pipeline
Exclude, the structure design of this rhone is relatively simple, exists weaken bridge intensity in actual use, cause stress collection
In, the problems such as potential safety hazard be present.Therefore the highway bridge bridge deck drainage facility used at present is difficult the hair for adapting to current social
Exhibition needs.And with the continuous development of road pavement technology, how to protect traffic safety of the rainy day on highway bridge bridge floor
Also the extensive concern of society has increasingly been caused, this workmen also to highway bridge bridge floor proposes requirements at the higher level.
The content of the invention
The defects of technical problem to be solved in the utility model is to overcome prior art and a kind of structural strength is provided
High, the convenient highway bridge bridge deck drainage facility of draining.
Technical problem of the present utility model is achieved through the following technical solutions：
A kind of highway bridge bridge deck drainage facility, including the drainage pipeline being laid under bridge floor, drainage pipeline inside are provided with
Support meanss, the cross section of the support meanss is Λ shapes, and the support meanss summit is located at the circular top surface of drainage pipeline,
The bottom of the support meanss extends towards to both sides.
Due to being provided with support meanss, good booster action is served to drainage pipeline, improves the overall knot of bridge
Structure intensity.
Technical scheme can be further：The drainage pipeline is semicircle, and base portion also extends towards to both sides, and two
While it is respectively provided with groove portion.
Technical scheme can be further：The base portion both sides of the bottom both sides extension insertion drainage pipeline of the support meanss
Groove portion in.Both simply consolidate by the mating connection mode in embedded groove, are easy to process.
Technical scheme can be further：The base portion both sides of the drainage pipeline are provided with the part extended obliquely upward.
Technical scheme can be further：The part extended obliquely upward on both sides is centrosymmetric.It is so that overall
Structure does not produce stress concentration effect.
Technical scheme can be further：The drainage pipeline is centrosymmetric.So that overall structure does not produce stress collection
Middle effect.
Technical scheme can be further：The support meanss are centrosymmetric.So that overall structure does not produce stress collection
Middle effect.
Technical scheme can be further：The height of the support meanss is equal to the radius of the drainage pipeline.
Compared with prior art, the utility model plays reinforcing and strengthened by setting support meanss in drainage pipeline
The effect of drain pipeline structure intensity, the overall structural strength for lifting bridge, will not cause stress concentration, band at drainage pipeline
Carry out potential safety hazard.Therefore, this highway bridge bridge deck drainage facility has the advantages that structural strength is high, draining is convenient.
