Description

With the deep water seal floor drainage of bell and spigot

Technical field

The utility model belong to civil air defense constructions and installations plumbing device arts, particularly a kind of easy construction, water seal deeply, the highly little deep water seal floor drainage with bell and spigot.

Background technology

Existing floor drain, generally include floor drain and leak body 1, bell jar 2, floor drain grate 3 and outlet 4, its outlet 4 is one section of short tube, short tube is suitable for reading leaks body bottom connection with floor drain, short tube protrudes from Lou bottom body downwards, for socket joint in the connected gutter mouth of pipe, as shown in Figure 1.

For ensureing the water seal effect of water-seal floor drain, the water seal depth of relevant national standard mandatory requirement water-seal floor drain reaches more than 50mm; Or adopt the shallow water of about 10mm envelope separately to add trap to meet the requirement of gutter draining seal.The advantage of shallow water seal floor drain is that floor drain itself is highly little, height with floor leveling layer or face brick layer thickness suitable.When ground patch block, drainage outlet is inserted on the pre-buried good gutter mouth of pipe, easy construction.

The position such as gas defence passage, simple decontamination room, wash and disinfectant house that civil air defense constructions and installations oral area arrives without shock wave, is row's decontamination wastewater, needs to arrange floor drain.But these positions use light water seal floor drain or other straight through floor drains to there is its particularity: due to the requirement of gas defence, ground not patch block, floor drain needs pre-buried; Trap is connect under needing as adopted common shallow water seal floor drain; Existing floor drain, without bell and spigot, needs to adopt drain cast iron pipe to connect.

The design and construction method that current national people's air defense relevant design specification and standard collective drawings adopt adopts common shallow water envelope floor drain, under connect trap, use drain cast iron pipe.Its major defect is: (1) country progressively eliminates drain cast iron pipe, unit in charge of construction's hand-to-mouth buying iron drain-pipe material and accessory difficulty; (2) be different from the open piping of surface structures, its trap is because being embedded in reinforced concrete floor, and the inspection hole of trap cannot play a role, and foreign material are difficult to dredging after trap blocking; (3) people's air defense base arrangement reinforcing bar density is high, and common trap is walked crosswise and taken up room greatly, is unfavorable for construction; (4) after adjunction trap, cause floor drain upper surface large to the vertical height of dewatering horizontal tube, sometimes need to thicken base plate thickness and could meet pipeline laying requirement, add Civil Cost.

As replaced light water seal floor drain with blastproof strainer, then cost is high, water seal is very shallow, use inconvenience.

In a word, the existing water-seal floor drain Problems existing for civil air defense constructions and installations oral area is:

1, due to without bell and spigot, the iron drain-pipe material that is difficult to purchase and accessory is needed to be attached thereto, construction inconvenience;

2, for meeting water seal requirement, make on floor drain large along the vertical height to dewatering horizontal tube after floor drain adjunction trap, pipeline laying is difficult, and cost is high.

Summary of the invention

The purpose of this utility model is to provide a kind of deep water seal floor drainage with bell and spigot, and easy construction, water seal is dark, overall height is little.

The technical solution realizing the utility model object is: a kind of deep water seal floor drainage with bell and spigot, comprise floor drain and leak body and outlet, described outlet is bilayer sleeve, it comprises highly identical inner and outer tubes, the end opening that lower edge and the floor drain of described outer tube leak body is tightly connected, the upper edge of described outer tube is tightly connected with the upper edge of interior pipe, and the gap drainage pipeline between described outer tube and interior pipe inserts from described outlet bottom, is socketed in outside interior pipe, within outer tube.

The utility model compared with prior art, its remarkable advantage:

1, with the common floor drain ratio of use, can be connected easily with without the steel pipe of bell and spigot, plastic pipe, easy construction, leakproof;

2, high water seal depth can ensure sealing effectiveness;

3, impurity deposits in floor drain water seal, depositing, more easily dredging than being embedded in reinforced concrete floor in trap.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is the structural representation of existing water-seal floor drain.

Fig. 2 is the structural representation of the utility model with the deep water seal floor drainage of bell and spigot.

Fig. 3 is the structural representation after floor drain bell jar is inverted.

The scheme of installation of Fig. 4 to be the utility model with the deep water seal floor drainage of bell and spigot be cast in people's air defense base plate.

In figure, 1 floor drain leaks body, 2 bell jars, 3 floor drain grates, 4 bell and spigots, pipe in 41,42 outer tubes, 5 sealing rings, 6 gutters, 7 reinforced concrete floors.

Detailed description of the invention

As shown in Figure 2, the utility model is with the deep water seal floor drainage of bell and spigot, comprise floor drain and leak body 1, floor drain grate 3 and outlet 4, described outlet 4 is bilayer sleeve, it comprises highly identical interior pipe 41 and outer tube 42, the end opening that lower edge and the floor drain of described outer tube 42 leak body 1 is tightly connected, the upper edge of described outer tube 42 is tightly connected with the upper edge of interior pipe 41, gap drainage pipeline between described outer tube 42 and interior pipe 41 inserts from described outlet 4 bottom, is socketed in outside interior pipe 41, within outer tube 42.

Sealing ring 5 is provided with in gap between described outer tube 42 and interior pipe 41.Sealing ring 5 can adopt rubber or other flexible material.

The utility model floor drain outfall establishes concave bell and spigot, can conveniently be connected with the pipeline without bell and spigot such as coating steel pipe, plastic pipe.When drainage pipe 6 end face connected is smooth, gutter termination is inserted the connection that can complete floor drain and gutter in bell and spigot.

Bell and spigot built-in rubber sealing ring, interface, may without draining seepage without the need to packing envelope, binding material; High water seal depth, utilizes separately the water seal of floor drain just can meet the requirement of civil air defense constructions and installations to floor drain gas defence sealing, can not establish trap.

Floor drain can adopt thin-wall stainless steel material, meets the requirement of underground wet environment to floor drain corrosion resistance.

Floor drain grate and floor drain leak body upper oral part can be adopted and be screwed, to reduce in every day use floor drain grate by the possibility of stealing.

The utility model and use common floor drain ratio, can be connected, easy construction, leakproof easily with without the steel pipe of bell and spigot, plastic pipe; High water seal depth can ensure sealing effectiveness; The impurity of deposition in dredging water seal, more more convenient than the depositing contaminants in trap in dredging reinforced concrete floor.
