Abstract

The invention discloses an anti-theft and waterproof drain well cover, belonging to underground pipe drain facilities. Two circular pits are uniformly distributed along the edge of the upper surface of the drain well cover; circular holes are arranged in the centres of the circular pits; bolts are screwed into manhole screw holes under the ground after penetrating through the two circular holes to connect the manhole and the cover to a whole; locking plates are plugged and welded on the bolt heads; and the cover cannot be opened via a tool by manpower. The plugged and welded locking plates can be cut via a cutting device by the owner of the drain well and the bolts are unloaded via a socket spanner, and then the well cover is lifted via a T-shaped hook. The well cover is not provided with an opening hole; an aluminium gasket is arranged under the bolt heads; and the attaching surface of the well cover and the manhole is filled with water sealing glue to prevent water. The drain well cover is an anti-theft and waterproof cover applicable to all kinds of drain wells.

Description

Anti-theft and waterproof drain well cover

The underground pipe trench facility of technical field.

There are a lot of inspection shaft lids on background technology avenue road surface.Inspection shaft in one's early years covers the formula of floating, shape such as disk, and the cast iron manufacturing has two to open slotted holes.Lay conveniently; Open as long as a T-shaped hook is therefore very easy to be stolen.Occurred several anti-stealing manhole covers in these several years, first kind is that chain is fastened formula, with an iron chains from well lid the inside the well lid chain on well head.The thief uses the sawed-off shot of a cable ring of handsaw, but just the well lid band chain is stolen together.Second kind is the hinge formula, and well lid is folding paper with well head and is connected, and theftproof improves, and tears that to decrease folding stolen open but still have.The third is the steel concrete formula, and it is little to steal the back use, allows the thief give up the idea; But weight is big, opens hard; And the rapid wear that collides with.These well lids can be intake because of open hole is arranged, and diminish the insulation environment of power cable, communication cable.

The technical problem that the summary of the invention anti-theft and waterproof drain well cover will solve is to prevent that the thief from can open with manpower hand-held tool (as existing T-shaped hook) that inspection shaft lid is committed theft and inspection shaft is stamped the function that stops rainwater.Prevent that the technical scheme that the thief opens the inspection shaft lid with the manpower hand-held tool from being, after with screw the walling crib in well lid and the build-in ground being connected together, head of screw and the weldering of well lid locking plate are dead.Motionlessly can not excise the well lid locking plate with electric slicer or oxygen cutting equipment.The technical scheme that stops rainwater is to add to fill out plastic sealing water between well lid and walling crib, and screw adds aluminium backing.

Anti-theft and waterproof drain well cover (accompanying drawing) is made up of well lid 1 and walling crib 5.Well lid 1 is discoid, upper surface uniform two round pools 2 that keep to the side, and there is circular hole the round pool center.Well lid 1 periphery lower end is the conical surface.Walling crib 5 is a concave shape, and uniform two screws in ring-type bottom surface of character cut in bas-relief the inside are corresponding with the circular hole position of well lid round pool 2 centers.In the walling crib 5 setting-in ground, upper surface flushes with ground.Remove walling crib 5 internal surface area soil, be coated with in right amount with plastic sealing water 6 as one sees fit at its peripheral inboard root angle.Well lid is opened and is closed lid again, and plastic sealing water 6 should shovel old being coated with newly.Well lid 1 is inserted walling crib 5, and the circular hole of well lid round pool 2 centers is aimed at walling crib 5 corresponding screws.Put into aluminium pad 8 in the round pool 2.Screw 4 passes aluminium pad 8 heart holes, is screwed in the walling crib screw with box spanner.Place on the ailhead of screw 4 having the inclination the round locking plate 3 in hole, and plug welding in heart hole, make locking plate 3 and screw 4 welderings extremely.When well lid is opened by inspection shaft master's house, available electric slicer or oxygen cutting equipment, the locking plate 3 of excision plug welding unloads screw 4 with box spanner, just can lift covers 1 with the T-shaped hook again.The thief commits theft and also need use these equipment, and the impersonal force hand-held tool can be succeeded.

Well lid 1 does not have open hole, and 5 of well lid 1 and walling cribs have plastic sealing water 6 shutoff, has aluminium pad 8 to remove the crack between screw 4 and round pool 2 bottom surfaces, has blocked permeable slit.Make that well lid 1 is waterproof to advance well.To need not the inspection shaft of waterproof, can not add plastic sealing water 6 and aluminium pad 8.

The advantage of anti-theft and waterproof drain well cover is an anti-theft and waterproof.All there is the required equipment that opens by force in inspection shaft master's house, though that well lid opens and closes the time spent is many, because of well lid is not often to open normally closedly, still has practicality.

Appended drawings is the anti-theft and waterproof drain well cover structure principle chart.

The casting of specific embodiment well lid 1 cast iron is made, and continues to use diameter, the thickness of existing well lid.Be round pool 2 places that mounting screw 4 is provided with, the part thickeies into axial boss 10.Attachment screw 4 should be used the M16 screw.Round pool 2 degree of depth are than screw 4 ailhead thickness and the big 1-2mm of locking plate 3 thickness sums; Round pool 2 diameters are than the big 1-2mm of sleeve outer diameter of screw 4 used box spanners; The Circularhole diameter of round pool 2 centers is than the big 2-4mm of screw 4 external diameters.60 ° of well lid 1 lower end periphery conical surface cone-apex angles.Walling crib 5 is cylinder iron casting system also; Pass the position of screw 4 on the corresponding well lid 1, the part is widened into radially boss 9, and the screw that is screwed into for screw 4 is arranged on it.There is flange 7 walling crib 5 periphery lower ends, and walling crib 5 is firmly embedded in the ground.Locking plate 3 thick 3mm, the iron plate punching out.Aluminium pad 8 thick 1mm, soft aluminium sheet punching out.Plastic sealing water 6 is commercially available fluid sealant.
