Abstract
The invention discloses a positioning limit loop used for preventing well lid settlement, and belongs to the field of municipal construction. The positioning limit loop comprises a cylindrical loop body (1) and a stepped table (2) arranged on the inner wall of the cylindrical loop body (1). The stepped table (2) is also cylindrical and 10-15 mm wide. The perpendicular distance between the top of the cylindrical loop body (1) and the top of the stepped table (2) is equal to the height of a well lid cylindrical extension section (4). When the positioning limit loop used for preventing well lid settlement is in use, the positioning limit loop is placed at the top of a pitshaft, then the cylindrical extension section in a well lid is placed on the stepped table serving as an adaption table of the cylindrical extension section, the well lid and the pitshaft are concentrically positioned, and well lid settlement can also be prevented. Since the perpendicular distance between the top of the cylindrical loop body and the top of the stepped table is equal to the height of the well lid cylindrical extension section, a lid body is right attached to a cylindrical loop body of the limit loop when the well lid is placed on the limit loop.
Description
Technical field
The present invention relates to municipal construction field, particularly to a kind of positioning limit circle of preventing well cover sedimentation.
Background technology
With the laying of town road and underground foundation facility, the quantity of inspection shaft also gets more and more.As shown in figure 5, well lid used by existing inspection shaft includes well lid lid 3 and the cylindric extension 4 being connected with well lid lid 3；And the external diameter of cylindrical shape extension 4 is less than the diameter of well lid lid 3.During use, sealing ring is set in the outside of cylindric extension 4, increases sealing.
But existing manhole shaft is straight-tube shape, there is no the hard point of cylindric extension it is impossible to stop well lid sedimentation.Pit shaft and well lid cannot ensure concentric, and location dimension is well over Criterion restriction.
Content of the invention
Transfinite to solve the problems, such as that prior art inspection shaft well lid is susceptible to location dimension, the invention provides a kind of positioning limit circle of preventing well cover sedimentation.
The technical scheme is that：
A kind of positioning limit circle of preventing well cover sedimentation, including cylindric circle body 1 and the faulting of slab ends 2 being arranged at described cylindrical shape circle body 1 inwall, described faulting of slab ends 2 is also cylindrical, and the width of described faulting of slab ends 2 is 10-15mm；Vertical dimension between described cylindrical shape circle body 1 top and faulting of slab ends 2 top is equal to the height of well lid cylindrical shape extension 4.
Preferably, described faulting of slab ends 2 is arranged at the bottom of described cylindrical shape circle body 1.
Preferably, described faulting of slab ends 2 is arranged at the middle part of described cylindrical shape circle body 1.
Preferably, the width of described faulting of slab ends 2 is 11-13mm.
Preferably, described cylindrical shape circle body 1 and faulting of slab ends 2 are made by armored concrete.
During the positioning limit circle being settled using the preventing well cover of the present invention, the positioning limit circle of the present invention is placed in the top of pit shaft, then the cylindric extension in well lid is positioned on faulting of slab ends 2, cylindric circle body 1 can make well lid accurate positioning, well lid center is made to be positioned in the range of Criterion restriction, faulting of slab ends 2, as cylindric extension adapting table, can stop well lid from settling.
Beneficial effects of the present invention are：
The positioning limit coil structures of the preventing well cover sedimentation of the present invention are simple, easy to use, dexterously make well lid and pit shaft concentric locating, and prevent well lid to settle, and are suitable to popularization and application.

Specific embodiment
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, the positioning limit circle of the preventing well cover sedimentation of the present invention includes cylindric circle body 1（The ring-shaped section and ring-shaped of cylindric circle body 1）.The inwall of cylindric circle body 1 bottom is fixedly installed faulting of slab ends 2, and faulting of slab ends 2 is also cylindrical（The section of faulting of slab ends 2 is in annular）, the width of faulting of slab ends 2 is 10-15mm（That is, the external diameter of faulting of slab ends 2 10-15mm bigger than the internal diameter of faulting of slab ends 2）；Vertical dimension between cylindric circle body 1 top and faulting of slab ends 2 top is equal to the height of well lid cylindrical shape extension 4.Cylindric circle body 1 and faulting of slab ends 2 are made by armored concrete.
Embodiment 2
As shown in Figure 1, Figure 2, Figure 4 shows, the positioning limit circle of the preventing well cover sedimentation of the present invention includes cylindric circle body 1（The ring-shaped section and ring-shaped of cylindric circle body 1）.The inwall at cylindric circle body 1 middle part is fixedly installed faulting of slab ends 2, and faulting of slab ends 2 is also cylindrical（The section of faulting of slab ends 2 is in annular）, the width of faulting of slab ends 2 is 11-13mm（That is, the external diameter of faulting of slab ends 2 11-13mm bigger than the internal diameter of faulting of slab ends 2）；Vertical dimension between cylindric circle body 1 top and faulting of slab ends 2 top is equal to the height of well lid cylindrical shape extension 4.Cylindric circle body 1 and faulting of slab ends 2 are made by armored concrete.
As shown in figure 5, well lid includes well lid lid 3 and the cylindric extension 4 being connected with well lid lid 3；And the external diameter of cylindrical shape extension 4 is less than the diameter of well lid lid 3.
During the positioning limit circle being settled using the preventing well cover of the present invention, first the positioning limit circle of the present invention is placed in the top of pit shaft and the spacing collar of the present invention and pit shaft be connected as a single entity, then the cylindric extension 4 in well lid is positioned on faulting of slab ends 2, faulting of slab ends 2 is as the adapting table of cylindric extension 4, well lid and pit shaft concentric locating can be made, and stop well lid from settling.Because the vertical dimension between cylindric circle body 1 top and faulting of slab ends 2 top is equal to the height of well lid cylindrical shape extension 4, when well lid is positioned on the spacing collar of the present invention, lid 3 is just fitted with the cylindric circle body 1 of spacing collar of the present invention.
