Abstract
The utility model discloses an anti-displacement inspection well which comprises a well seat, a wall chamber, a shaft and a well lid, wherein the well chamber is wrapped with a backfill layer; the shaft is arranged at the upper part of the well chamber and buckled with the well lid; an anti-displacement concrete well ring is arranged between the well lid and the shaft in a cast-in-situ manner and covered with an asphalt concrete surface layer located on the same plane with the pavement; the anti-displacement concrete well ring is wrapped with a cement stabilization gravel ring; and cold rolling threaded steel bars which are tightly close to the outer edge of the well lid are embedded into the anti-displacement concrete well ring and uniformly distributed according to a central angle. The anti-displacement inspection well is simple in structure, and the construction speed is high; and the integrity of the inspection well ring is guaranteed.
Description
Technical field
The utility model belongs to underground foundation facility technology field, is specifically related to anti-displacement manhole.
Background technology
Along with the increasing of various places to urban infrastructure dynamics of investment, urban road length and quality have all gone up a new step, but on urban road, the manhole of all kinds of pipe networks has been buried much hidden danger to highway construction quality, if process bad, no matter be major trunk roads or subsidiary road, road time of coming into operation is not long, just find that well face sinks, walling crib is asphalt surface course cracking, breakage around, cause the phenomenons such as crib and road surface elevation difference be excessive, both affect the smooth degree on road surface and attractive in appearance, also had a strong impact on comfort level and the safety of driving.For not only effective but also economic addressing the above problem, incorporation engineering practical experience has designed anti-displacement manhole walling crib.
Utility model content
The utility model is intended to overcome the defect of prior art, and anti-displacement manhole is provided, and this apparatus structure is simple, and workman easily grasps and operates, and speed of application is fast; Ensure the globality between walling crib rigidity ruggedized construction and semi-rigid type base, flexible cladding structure.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Anti-displacement manhole, comprise well seat, well chamber, pit shaft, well lid, well outside is enclosed with backfill layer, top, well chamber is provided with pit shaft, on pit shaft, be snapped with well lid, between well lid and pit shaft, be cast with anti-displacement concrete walling crib, anti-displacement concrete walling crib top is coated with road surface in conplane asphalt concrete pavement, anti-displacement concrete walling crib outside is enclosed with cement Stability Gravel circle, in anti-displacement concrete walling crib, be embedded with the tightly cold-rolled threaded reinforcing steel near well lid outer rim, cold-rolled threaded reinforcing steel is evenly arranged by central angle.
Further, cement Stability Gravel circle width is 50CM outside pit shaft.
Further, cold-rolled threaded reinforcing steel quantity is at least the cold-rolled threaded reinforcing steel of 3 Φ 22.
Further, cold-rolled threaded reinforcing steel length is greater than walling crib height, the long 22-25CM of cold-rolled threaded reinforcing steel.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is simple in structure, and workman easily grasps and operates, and speed of application is fast; Ensure the globality between walling crib rigidity ruggedized construction and semi-rigid type base, flexible cladding structure, settlement prevention; Can meet the requirement of the each side such as safety, quality and function; There is good Social benefit and economic benefit.
Brief description of the drawings
Fig. 1 is the top view of the anti-displacement manhole of the present invention walling crib;
Fig. 2 is the front view of the anti-displacement manhole of the present invention walling crib;
Fig. 3 is the schematic diagram of the anti-displacement manhole of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, anti-displacement manhole, comprise well seat, well bore 8, pit shaft 7, well lid 1, well bore 8 outsides are enclosed with backfill layer, well bore 8 tops are provided with pit shaft 7, on pit shaft 7, be snapped with well lid 1, be cast with anti-displacement concrete walling crib 2 between well lid 1 and pit shaft 7, anti-displacement concrete walling crib is the anti-displacement concrete walling crib of label C25.Anti-displacement C25 concrete walling crib top is coated with road surface 6 in conplane asphalt concrete pavement 5, and anti-displacement C25 concrete walling crib outside is enclosed with changes the cement Stability Gravel circle 4 of filling out, and cement Stability Gravel circle width is 50CM outside pit shaft.In anti-displacement C25 concrete walling crib, be embedded with tightly 3 Φ, 22 cold-rolled threaded reinforcing steels 3 near well lid outer rim, cold-rolled threaded reinforcing steel is evenly arranged by central angle.Cold-rolled threaded reinforcing steel length is greater than walling crib height, long 22-25CM.
Technological principle changes and fills out 4% cement Stability Gravel that 50cm is wide, the degree of depth is more than or equal to 100cm around newly-built manhole shaft, builds the C25 concrete of width 36cm, height 20cm under well lid.Preferably, anti-displacement concrete inspection well walling crib is buried the cold-rolled threaded reinforcing steel of three Φ 22 underground, and length 22-25cm, by 120
0central angle is arranged.
The utility model is simply popular, and workman easily grasps and operates, and speed of application is fast; Ensure the globality between walling crib rigidity ruggedized construction and semi-rigid type base, flexible cladding structure, settlement prevention; Can meet the requirement of the each side such as safety, quality and function; There is good Social benefit and economic benefit.
The foregoing is only explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
