Abstract
The utility model provides an oval airtight type fire -water pond manhole which characterized in that: flange nozzle stub, rubber seal, clamp bolt and ring flange blind plate including the elliptic type, the flange nozzle stub set up in the lower part of fire -water pond side, the department is equipped with rubber seal and ring flange blind plate at the flange nozzle stub mouth of pipe to it is sealed fixed through clamp bolt. The utility model discloses an optimize present fire -water pond manhole position and structure to reaching the manhole and satisfying under the prerequisite that fire -water pond overhaul to maintain, it is too big to reduce the invalid volume of improper messenger fire -water pond that sets up because of the fire -water pond manhole, reduce fire -water pond area, reduce the cost, make things convenient for personnel to get into fire -water pond and carry out in the future maintenance and maintenance.
Description
Technical field
The utility model relates to a kind of fire prevention field, is specifically related to a kind of oval hermetic type fire cistern manhole.
Background technology
Conventional fire cistern inspection manhole is generally arranged on the top (seeing shown in accompanying drawing 1-2) of fire cistern sidewall at present, is non-pressure fire cistern manhole. Under manhole operated by rotary motion structural beams, manhole size is generally diameter 800, considers the impact of superstructure beam, fire cistern top generally have 1500-2000mm cannot storage of water idle space, cause the feature that fire cistern floor space is large. And manhole is arranged on top, people enters in fire cistern, and stainless steel cat ladder is set inside and outside fire cistern, and people only has the manhole of 800mm to enter fire cistern by cat ladder from diameter, cumbersome, also easily goes out security incident.
Summary of the invention
The purpose of this utility model is to provide a kind of oval hermetic type fire cistern manhole, the utility model is that current fire cistern people hole site and structure are optimized, meeting under the prerequisite of fire cistern repair and maintenance to reach manhole, reduce because of the improper fire cistern Iinvalid volume that makes of fire cistern manhole setting excessive; Reduce fire cistern floor space, reduce cost, facilitate personnel to enter fire cistern and carry out maintenance and maintenance in the future.
The utility model is achieved in that
A kind of oval hermetic type fire cistern manhole, it is characterized in that: comprise disciform flange short tube, rubber seal, hold-down bolt and ring flange blind plate, described flange short tube is arranged on the bottom of fire cistern side, be provided with rubber seal and ring flange blind plate at flange short tube mouth of pipe place, and seal fixing by hold-down bolt.
The airtight pressure-bearing type fire cistern of ellipse of the present utility model manhole, is arranged on the bottom of fire cistern side, is ellipse, is airtight pressure-bearing type. Employing is arranged on the bottom of fire cistern side, and maintenance cat ladder need not be set, according to human body body feature, and manhole oval in shape, maintainer is easy enters repair and maintenance in fire cistern from fire cistern. Adopt airtight pressure-bearing type structure, the position of fire cistern manhole can be determined according to engineering actual conditions, need not consider the conditions such as water level, the fire cistern useful space is able to effective utilization, fire cistern top generally reserved 300mm water level superelevation just, than conventional 1500～2000mm cannot storage of water idle space saving a lot, pond floor space is greatly reduced, and reduces cost. When need to overhauling, fire cistern should want emptying fire cistern.
The utility model substantive distinguishing features and progress are:
The invention belongs to current fire cistern people hole site and form are optimized, meeting under the prerequisite of fire cistern repair and maintenance to reach manhole, reduce because of the improper fire cistern Iinvalid volume that makes of fire cistern manhole setting excessive. Reduce fire cistern floor space, reduce cost, facilitate personnel to enter maintenance and maintenance that fire cistern carries out.
