4, accompanying drawing explanation and embodiment
Fig. 1 is that sewer and sand sediment trap are at underground schematic diagram.Fig. 2 does not have fenced in square desilting basket schematic diagram.
Fig. 3 is with fenced in circular desilting cage schematic diagram.Fig. 4, the 5th, a kind of circular desilting basket schematic diagram.
Fig. 1, sand sediment trap 1 is arranged in sewer 4.Sand sediment trap also can be called inspection shaft.The difference of sand sediment trap of the present invention and known manhole is that sand sediment trap is also with desilting recessed 5.Desilting recessed 5 is for placing desilting bucket.Sand sediment trap has the function that facilitates desilting.As can be seen from Figure 1, desilting recessed 5 is lower than sewer 4, and when current process sand sediment trap, the silt in water is because natural gravity drops in desilting bucket.There is with fenced in desilting cage the effect that slows down current, make the silt in water more easily drop to desilting bucket.Sand sediment trap, with step 2, is installed desilting cage in order to hanging.Bridge type inspection well cover 3 is installed on sand sediment trap 1.Bridge type inspection well cover 3 is T-shaped with inspection shaft 1, and forward install on road surface.The two ends of bridge type inspection well cover exceed 5 centimetres, inspection shaft edge or more than.Be preferably in more than 10 centimetres.The two ends of bridge type inspection well cover are long, large with contact area of ground, and therefore dispersive pressure is effectively not easy depression.Desilting cage available metal or/and cement or/and timber separately or combination make.Sand sediment trap available metal uses on-the-spot installation or/and cement, or/and timber is made alone or in combination or prefabricated forming, is transported to.
Fig. 2, does not have fenced in desilting basket 6 with suspension ring 7 and desilting bucket 8.Suspension ring are for the lifting of desilting basket 6.Desilting bucket 8 can be put into recessed 5 li of desilting.The size of desilting bucket 8 and desilting are recessed 5 corresponding.Desilting bucket 8 peripheries can be with sealing ring, prevents that silt from entering desilting recessed 5 from the gap between desilting bucket 8 and desilting recessed 5.
Fig. 3, desilting cage 9 is with fence 10 and desilting bucket 8.Desilting bucket 8, with separator card 11, can separate with desilting cage, the convenient silt of removing in desilting bucket.Also desilting bucket can be unloaded and transports from desilting cage, change a desilting bucket.There is with fenced in desilting cage the effect that slows down current, make the silt in water more easily drop to desilting bucket.Space between fence can be used as suspension ring and uses.Desilting cage has bridge type inspection well cover 3 to be fixedly connected with it on top, can be also that known inspection well cover is fixedly connected with desilting cage.Because desilting cage entirety is very large, very heavy, inspection well cover is not easy stolen.The mouth limit of desilting cage can be greater than the mouth limit 21 of sand sediment trap, step 2 places in order to hanging at sand sediment trap 1.
Fig. 4, the similar hanging basket of desilting basket 13, with suspension ring 12 and desilting bucket 8.Suspension ring 12 are camber arch shape.Fig. 5 is the top view of Fig. 4.The difference of desilting cage and desilting basket is height.The height of desilting cage 6 is close with the inspection shaft degree of depth.Desilting basket 13 is very short, can only be placed on separately the recessed middle use of desilting.
