Description

Taper type locking manhole for preventing noise and departure

The present invention relates to a taper-type locking manhole for preventing noise and separation, wherein a taper is formed on the manhole cover member and the cover support member and is coupled to a tapered locking structure, thereby preventing noise and separation of the manhole cover member and inflow from the outside. It is about a tapered locking manhole for preventing noise and separation to prevent accumulation of water.

Manholes are installed on roads or sidewalks for the management of underground facilities, and are divided into bases and covers, and are cast-molded. Most manhole covers are designed to remain closed against the manhole support by their own weight.

In general manhole products, the angle at which the manhole cover and the manhole support are combined (closed) is vertical, and the manhole cover and the manhole support are designed to have a certain distance. In this structure, when a vehicle passes over the manhole cover at high speed, noise is generated due to the impact, or in severe cases, the manhole cover may be separated from the manhole support.

In order to solve this, the present applicant applied for Korean Patent No. 10-1453835'Tapered manhole preventing noise and separation', and disclosed a technology for preventing the above noise and separation by providing a taper type manhole. There is a bar. However, between the manhole cover and the manhole support, inflows such as dust, garbage, soil, and sand from the outside may accumulate and accumulate, or the manhole cover and the manhole support may be corroded together with the inflow, thereby opening the manhole cover. Difficulties that do not open well may occur when playing.

This may be a problem that occurs because a gap between the manhole cover and the manhole support, that is, a large tolerance in design, is allowed. Although it is highly possible to solve the above problems by precision casting or precision machining, there is a limit to the manufacturing cost of manhole machining, so it can be seen that an allowable tolerance is necessary.

In addition, in order to solve the above problem, a method of fixing the manhole cover and the manhole support with a locking device has been proposed, but this may cause a gap due to an impact and the locking device may be released. There is a risk of causing a major accident by damaging the wheel of the car.

Korean Patent Laid-Open Patent No. 10-2002-0081946 (published on October 30, 2002) Korean Patent Registration No. 10-1037330 (Registration Date: 2011. 05. 20. Registration) Korean Patent Registration No. 10-1453835 (Registration date: 2014. 10. 16. Registration)
