Description
Technical field
The utility model relates to a kind of sealed, burglarproof well lid, and it belongs to a kind of by cast iron and the compounded sealed, burglarproof well lid of concrete.
Background technology
In urban construction, there are many local needs to use well lid, as inspection shafts such as tap water, coal gas, power cable and communication cables.These well lids generally adopt cast iron to make, and this well lid cracky there is no sealing, and rainwater enters in the inspection shaft especially easily, and corrosion power cable and communication cable cause power failure or communicating interrupt.For preventing that rainwater from entering in the inspection shaft, people have designed a kind of double-deck casting iron well lid and have stoped rainwater to enter.But, not only waste resource but also lose easily, and sealing effectiveness is bad because this well lid is all made by cast iron.
Summary of the invention
The purpose of this utility model be solve cracky that existing casting iron well lid exists, do not have sealing and non-anti-theft technological difficulties and provide a kind of good airproof performance, can antitheft and sealed, burglarproof well lid not cracky.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: the sealed, burglarproof well lid, it comprise one by cast iron skeleton and the compounded well lid of concrete, one match with well lid and to merge the well seat of making by cast iron bead, steel grid and concrete, wherein: it also comprises cover opening device and sealing ring, cover opening device is located at the edge of well lid, and sealing ring is located at the joint portion of well seat cast iron bead and well lid cast iron skeleton.
Described cover opening device is any one in bolt cover opening device or the draw ring cover opening device.
The cross section of described sealing ring is any one in circular, square or the U-shaped.
Well lid and well seat be shaped as in circular or square any one.
Described cast iron skeleton is made up of shirt rim, groove, grid frame and ring-type lower edge, the shirt rim is located at the outer edge of cast iron skeleton, grid frame is located at the centre of cast iron skeleton, groove be located at shirt rim and grid frame between and the two is linked together, the ring-type lower edge is located at the place, outer of grid frame bottom surface and is connected as a single entity with grid frame.
Described bolt cover opening device is made up of opening bolt, sealing mat and nut, and the head of opening bolt is provided with an open hole, and sealing mat is located at the top of opening bolt, and nut is located at the bottom of opening bolt.
Described draw ring cover opening device is made up of draw ring, top nut, sealing mat and lower nut, and top nut is located at the top that draw ring is provided with thread segment, sealing mat be located on the draw ring and be positioned at top nut below, lower nut is located at the bottom that draw ring is provided with thread segment.
Because the utility model has adopted technique scheme, well lid sealing and waste problem of resource have been solved, and therefore improved supporting capacity and non-skid property, compared with background technology, have good airproof performance, can be antitheft and advantages such as cracky, non-slip and noiselessness not.
