Description
Technical field
The invention belongs to building engineering field, more particularly to a kind of bridge pier of bridge.
Background technology
It is inquired by patent consulting website soopat, using bridge, underground, monitoring as key search, applicant retrieves
Two pieces patent is the 2016204263867 and refined 2014202536451 of Zhejiang Ocean university respectively, and Zhejiang Ocean is big
What is learned is the underwater detection device of a mechanical type, and refined is to utilize acoustics multi-beam range measurement principle, this two pieces patent
The situation of intuitive visual inspection apparatus observation bridge pier underwater portion it is not related to, in addition, either underwater or low-lying location
Bridge, bridge pier always some be imbedded in underground, the physical state of this part of bridge pier also directly with the longevity of bridge
It orders and safety-related, for example bridge is eaten into erosion by termite or bridge periphery acidity is higher, and concrete is formed to corrode and is made
With, and termite medicine, by retrieval, there are following frequent species：DDVP, phoxim, chlopyrifos, Le Siben, sevin, bromine cyanogen
Chrysanthemum ester, Biphenthrin, imidacloprid, avermectin, aluminum phosphate, bitter bark, Siberian cocklebur.
By checking, termite medicine is based on synthetic pyrethroid class pesticide and organophosphorus pesticide, synthetic pyrethroid
Class drug and organophosphorus pesticide easily alkalize failure, and the lime in cement is exactly exactly alkaline matter, this gives bridge pier prevention termite
Bring problem.
Invention content
Technical characteristic：A kind of bridge pier, it is characterized in that：
Bridge pier is made of following several technical essentials, these technical essentials can be used individually, can also combine use,

Specific embodiment：Applicant is introduced with reference to attached drawing：
Bridge pier is mainly made of top cap 7, pier shaft 1, basic 5 three parts, and the top cap refers to the top of bridge pier, top cap be for
Body of a bridge structure is shelved, pier shaft is the middle section of bridge pier, and basis is the lower part of bridge pier, and basic area directly decides bridge
The size of load-bearing, either underwater or land, basis is most of to be buried in underground,
Under identical material condition, such as identical volume of concrete and identical steel, if the height that bridge pier needs are built
Spend it is identical, actually or entity structure hollow-core construction, the structure of bridge pier is more safe and reliable, due to hollow-core construction bridge pier more
Greatly, correspondingly, in the case that bridge weight is certain, to the pressure smaller of bridge pier, then have a bit, hollow-core construction is conducive to observation bridge pier
Physical state, it is found that after bridge pier goes wrong, there is certain repairing effect, analogy finds that bridge pier is damaged, such as hit
It hits, then, it is possible to hollow parts concrete perfusion, reinforcement structure, there is discharge outlet in bridge pier lower part, the effect of osculum is
By hollow space water discharge that may be present, especially winter, water freezing, volume become larger, and exist to bridge pier structure and adversely affect.
Whether there is water according to bridge pier lower part, the laying of camera is divided to two kinds, and one kind is that have water, and camera head protecting pipe is from bridge pier
There is a certain distance, camera head protecting pipe has glass, and camera is facilitated to shoot with video-corder bridge pier underwater portion, and one kind is anhydrous, camera
Protection pipe is to be close to basic laying, and camera head protecting pipe equally has glass, observes basal status by glass, anhydrous bridge pier is taken the photograph
As the basic part that head is shot with video-corder is fairly limited, still, by laying a certain number of cameras, it is still able to observe that bridge pier shape
The more area of condition, especially termite, it should be noted that underwater or under ground portion is one using camera head monitor bridge pier
Very simple technology, still, significant for bridge structure, some bridges duck in drink for a long time, physical arrangement
It is washed away by flow, if flow velocity quickly or flow pH value is relatively low, there is concrete structure very big influence,
Citing, Cili the Lishui River bridge underwater portion have reformed into cellular, discharge water maintenance if not area just outside a city gate power station, all also cover in drum
In.
Termite is due to that can eat into erosion concrete, to bridge structure there are great destruction, but synthesize pyrethroid
Esters medicine and organophosphorus pesticide easily alkalize failure, using camera, observe bridge pier there are termite and then utilize termite
Termite medicine is perfused in medicine syringe, is killed, the termite medicine syringe in hollow structure has medicine outlet, drug along bridge pier inner wall
Entrance is directly communicated with bridge floor, in this way, with regard to termite medicine can be perfused directly on bridge floor, and the termite medicine syringe of foundation is then
It is communicated with basic outer wall, termite medicine kills termite by basic outer wall.
Bridge easily sets height-limiting frame, still, ship from colliding bridge also has news report, for example, eastern unlike highway culvert
Ship from colliding bridge accident just once occurred for ten thousand river of tabernaemontanus bulrush, and the principle of buoy is that float tube is connected with the water surface by intake-outlet, according to
According to the principle of linker, the water level of float tube can with the fluctuation in stage in river, floating ball fluctuation with the fluctuation of river water, so as to
Buoy on floating ball can also move up and down, and the lifting value of buoy is converted into bridge by computer allows current numerical value, still
Bridge height will not change, and the lifting value of buoy is converted into bridge by computer allows current numerical value, be measured by buoy
Bridge allow by ship height just there are one accurate numerical value, by above-mentioned data using wireless network, be sent to needs
By the captain or operating personnel of bridge, the numerical value conversion of measurement into a kind of method of computer data be that scale is scribed on buoy,
For scale value using buoy lower end as maximum value, buoy upper end is 0 degree, and code reader, code reader and computer are set in the upper end of float tube
Connection scans the altitude information that buoy indicates by code reader, and the data transmission of scanning to computer is utilized formula meter by code reader
Calculate, formula is h=h1-h2, and h is exactly to allow ship headroom, h1 be bridge allow by highest bit value, h2 is barcode scanning
Device transmission data, and h setting safety warning data, when h numerical value be less than safe early warning numerical value when, ship by when lead to
It crosses artificial or machine and sends warning information, to ship by implementing control, do not have the ship of current condition, do not allow to pass through,
Especially river Flooding, bridge allow by ship height tailing off, still, due to lacking specific data, some captains
May leave things to chance, be forced through by rule of thumb, there is a specific data, ship by when can just know what is what, it should be noted that
Bed level do not allow current ship highly only occur in flood it is surging when, so not need to measure entire riverbed high for buoy
Degree, because riverbed is generally all higher, dynamically measuring entire bed level does not have practical significance,
When weather conditions are severe, during unsuitable navigation, in discretion Quan captain's hand whether actually navigation at present, as east
The star shipwreck accident of side is exactly bad weather, captain fails to order to suspend in time pull in shore caused by, if weather conditions are not
It is suitble to navigation, if passenger knows rather than the independent ruling of captain, the star accident in east perhaps can be to avoid, by warning,
It is also a kind of reminding effect, control department monitors ship and navigates by water in violation of rules and regulations, and ship is supervised, which to suspend also, to play a role.
