Abstract
The utility model relates to a manhole with a washer, which is composed of a manhole body, an elastic washer and a manhole cover, wherein, the washer can be designed to be reverse staircase type circular and annular. A bracing ring corresponding to the washer is arranged at the inner side of a manhole wall, and is used for bracing the washer, and the edge of the back side of the manhole cover is arranged at a convex ring. In this way, the integral washer is arranged in the manhole wall, and is braced by the bracing ring. The manhole cover is covered on the washer, and the convex ring of the back side is arranged at the inner side of the washer. The manhole which is used can not generate impact sound when a vehicle runs on the manhole, and wheels impact the manhole cover. Accordingly, the noise pollution is reduced.
Description
The utility model relates to a kind of inspection shaft that has packing ring.
Inspection shaft is a manhole, is the device that underground utilities etc. must be equipped with when being provided with.Common inspection shaft is made up of the borehole wall (well bore) and well lid two parts.These inspection shafts often are placed in the middle of the road.Because long vehicle ', the other road surface of inspection shaft changes, and the vehicle wheel can cover at inspection shaft in direct punching press.Well lid is suitable for reading with well bore to be that rigidity contacts, so when the vehicle wheel is stamped into well lid, the very big bump sound can take place, causes city noise pollution, influences the environment peace and quiet.
The purpose of this utility model is to design a kind of inspection shaft that can not send the sound when the punching press of vehicle wheel.
The inspection shaft of the utility model design is made up of the borehole wall (well bore), packing ring, well lid.Wherein, packing ring is arranged between the suitable for reading and well lid of the borehole wall, and its size is suitable for reading and well lid coupling with the borehole wall, as shown in drawings.Packing ring adopts rubber-like material, for example vulcanie.
Inspection shaft packing ring in the utility model can be designed to various ways.For example, gasket design becomes inverted steps formula garden annular (seeing accompanying drawing).Corresponding with it, in borehole wall lower inside suitable for reading appropriate location a bracing ring is set, be used for supporting bead.Well lid reverse side proximal edge place is provided with a bulge loop (seeing accompanying drawing), and this bulge loop can be seated at the inboard of garden ring washer, and the edge of well lid contacts with the packing ring of well head.
The inspection shaft that has elastic washer when the punching press of vehicle wheel is on it, because the effect of elastic washer just can not clashed into the sound, has reduced noise pollution.
Further specifically describe the utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structure sectional side elevation of the present utility model.
Number in the figure: 1 is the borehole wall (well bore), and 2 is packing ring, and 3 is well lid, and 4 is the bracing ring of borehole wall inboard, and 5 is the bulge loop of well lid downside, and 6 is roadbed.
Embodiment, as shown in drawings, the internal diameter of supposing inspection shaft wall (1) is 70cm, then the diameter of well lid (3) diameter and packing ring (2) also is 70cm.Packing ring (2) adopts vulcanie, is designed to inverted steps formula garden annular, and its interior diameter is 60cm, and the first rank thickness of falling from power is 1.5cm, and width is 3cm, and the second rank thickness of falling from power is 2cm, and width is 2cm.Be complementary with packing ring (2), at the borehole wall (1) lower inside 4cm suitable for reading place a bracing ring (4) is set, its width is 3cm, consistent with the first step width of packing ring (2), its internal diameter is 64cm, and consistent with the external diameter of the 2nd step of packing ring (2), the thickness of bracing ring is generally 3.5cm, be used for supporting bead, and can bear extraneous pressure.Bracing ring (4) is fixing with the borehole wall (1) welding.Well lid (3) thickness is 2.5cm, and its reverse side isolated edge 5cm place is provided with bulge loop (5), and ring is 3.5cm highly, and thickness is generally 1cm and gets final product.Like this, the external diameter of bulge loop (5) is 60cm, just in time it is seated at the inboard of packing ring, so that with the well lid permanent position.During installation, the well bore that will be welded with bracing ring earlier places suitable position, and staged garden ring washer is positioned on the borehole wall bracing ring suitable for reading, and at this moment, first step downside of packing ring is put forth effort on the bracing ring, and second step is seated at the bracing ring inboard.Then, well lid is covered on packing ring, at this moment, the bulge loop of well lid reverse side is seated at the inboard of packing ring.
Claims (2)
1. an inspection shaft that has packing ring is made up of the borehole wall, packing ring, well lid, it is characterized in that, packing ring is arranged between the suitable for reading and well lid of the borehole wall, and its size is suitable for reading and well lid coupling with the borehole wall.
2. according to the described inspection shaft that has packing ring of claim 1, it is characterized in that gasket design becomes inverted steps formula garden annular, corresponding with it, be provided with a bracing ring that is used for supporting bead in borehole wall lower inside suitable for reading appropriate location, well lid reverse side proximal edge place is provided with a bulge loop that can be seated at the packing ring inboard.
