Road surface well builds the circumstance that passes through in the car of accumulate over a long period to fall, hard to avoid can produce cave in situation. Additional as a result of below it is blacktop face commonly, so of cave in fiercer and fiercer, to this problem, the ceaseless effort that covers professional through the well was invented eventually prevent new-styly sedimentation well lid, very good settlement the worry that well lid brings.

So prevent sedimentation how is well lid to prevent what well lid sinks? Prevent sedimentation the wide margin design that the well builds, the load pressure that makes come from upside is gone to dispersedly through pedestal law layer of road surface structure, make bear of susceptive of well body place reduces 0.8 above, protected Jing Gaizhou to surround road surface thereby, prevent to sedimentation.

Prevent sedimentation the characteristic that the well builds:

1, be united in wedlock cheek by jowl with road surface, cause seeper not easily.

2, avoid to be applied directly to well body pressure, reduce the possibility that sink greatly.

3, prevent the road surface side Jing Gaizhou effectively to appear turn over loose, disintegrate, mar wait for a phenomenon. In construction respect need not prefab and large concrete well annulus, construction is convenient and quick, one-time construction ends, can open liaison man. Need to cover the well prize to loosen and use simple and easy device only when maintenance perpendicular unplug tall, need not change well lid, workload is all.

Prevent sedimentation the design concept that the well builds:

Encircle the well the one part of road surface of regard as road, make one of body are changed, changed well lid and the link way that the well encircles, the well circle that makes the well is built and union of layer of road surface bitumen are a whole, changed the condition getting power of well circle, the travel load of near 0.8 above passes well circle to be absorbed by road surface directly, below exterior action, well group will be automatic as the road
