TRANSPORT PACKAGING

1 - binding; 2 - place slinging

						Package weight, kg

Since these designs are the most widened, then, obviously, they are characterized by a large number of advantages, among them:

The stinks of the building show the grandeur of the venture.
The vaga is great to attach to the fact that it is impossible to open the lid in a slippery way and it won’t be seen under the hour of transport transfer.
They rejoice at a democratic price.
Do not know the evocative infusions.
High frost resistance.
Trivaliy term of exploitation.
They can be of a different size and different vaga, depending on them, they are different tasks. Important and easy installation. Easy vikoristovuyutsya in park areas, squares, on sidewalks, on summer cottages for closing septic tanks and drainage wells. Heavy, at their own pace, are installed on the highways, autobahns, and middle and intensive traffic. Can vikoristovuvatisya and on industrial objects, and automobile highways, and thermal, and gas barriers.
The ribbed surface of the lid helps to increase the strength of the structure.

What is worth the shortcomings, then we are ahead of the vaga. Vіn spriyaє zahistu kolodyazіv, but at the same time it is possible to move outbuildings, їhnє pіdnyattya. Also, such installations are suitable for villains, so that you can give a chavun.

Chavunny hatch DERZHSTANDARD 3634 99 appointments for installation on observation wells of underground communications. The variety of views is connected with the minds of exploitation, resistance to navantage and safety technology. The preparation of raw materials, together with the material, is regulated by the established international standards.

Tipi zahisnih lukіv and їх recognition

Access to the review of underground communications, such as sewerage, cable, pipe systems, secures the sewer hatch of the observation well.

The main recognition of the roofs is the security of the safety of pedestrians, cars, and also the defense of the protection of the poor and the sight of the land that is under the ground.

The standard for chavunni caps for viewing wells is broken down on the basis of light powers to marking, design, testing and control of the viability of virobs. Hatches are made to meet GOST 3634 99 "Hatches for observation wells and doshchepriymach storm water wells".

Fallow in the minds of the installation of the vanity, they are divided into different types of hatches. The stench is due not only to the ease of installation and operation, but also to the aesthetic design of the structure, the savings of technical parameters, and regardless of the minds of the victorious.

Nadvazhkі zahisnі konstruktsії dіamet yakh stanovit 550 mm, vаga 155 kg, rated 600 kN, are installed in the docks and airfields.

Heavy main hatches with a weight of about 140 kg are mounted on the mains, vitreous weight up to 400 kN. On motor roads with intensive traffic, a 120 kg mass and a nominal load parameter of 250 kN are installed.

The middle ranges, which show the load up to 125 kN, are installed near the living areas and roads with intermediary transport loads. Installation of light sewer hatches, the weight of which can be 65 kg, is carried out on sidewalks, pishohidnyh zones, lawns.

Hatches for wells are made in accordance with the established standard behind hardened armchairs. The forks are not to blame for the defects that are added to the fiber.

The design was given the presence of at least one opening, which ensures the possibility of opening the lid. It is to blame at once for flying to the supporting surface and freely entering the body.

To characterize chavun hatches of circular wells, then for them there are 2 main parameters - the outer diameter and the inner diameter of the opening.

All overall dimensions are prescribed in GOST 363499, but in practice one can know the chavun caps of the round wells with a diameter of 380-810 mm. Rozmіr povnogo vіdkrittya become 450-550 mm.

The lid of the zahisnoy design can be square in shape. The minimum length of the side can be 300 mm and it can be increased by 50 mm with leather trim. The optimal size of such a design is 800 mm.

Technical characteristics

The chavun hatches are obov'yazkovo equipped with an elastic gasket between the upper and lower parts of the structure. The material, from which one prepares the stocks for surveying wells, may conform to the sovereign standard.

Hatch covers, cases are made from gray chavun brand SCH20. At the time of consumption, it is allowed to replace the material with a different brand, for the sake of maximum efficiency.

On the outer part of the structure of the manholes, the plant-virobnik should be marked, and on the inside - the date of preparation. If you have a copy of your passport, you will receive data about the test, the warranty term of operation, the date of acceptance by technical control.

The skin batch is subjected to re-testing for mechanical properties and testing to the influx of mechanical advances.

The term of exploitation of chavunny hatches should be no less than 80 years, and the profitability, which is shown, is up to 90 tons. The stench is up to temperature drops. The only shortfall of chavunnyh constructions is high varity.

Oblashtuvannya technological well due to the need for regular maintenance and in-line repair of various types of highways. That is why such constructions are superfluous and will ensure access to underground communications.

Installation and operation

Strongly closed manhole covers do not guarantee complete safety and protection from falling into the opening of various objects. Head meta, for which, when preparing vicorist, an important material, tse zapobigannya vpadkovy falls.

Chavunna krishka to finish off the important thing, so for її perevaga that usunennya it is necessary to apply a strong force. Chavun is resistant to the influx of atmospheric minds, corrosion, mites, does not crack under the influx of navantage.

There is more access to the inspection window, in the middle of which are the nodes of the separate and locking equipment, as well as the mechanisms for control and management of the systems that secure the hatch cover.

Open the well of guilty obov'yazkovo zakrivatisya, shchab їх could not vіdkrit vіpadkovі unilateral navantazhennya but tsіkavi passers.

If the installation of the hatch is required to be done on the garden space, then the main evidence must be reported during the installation of the supporting part of the structure. Open the support tower, which is necessary for the yoke armored structure.

The lid of the sewer well is guilty of hanging over the surface at a different location on the lawn. When installing on the prozhdzhiy part, it is necessary to ensure the minimum damage to the area, where the cover will be installed, to ensure the water drain.

Ease of installation is closely related to the current rules of operation. The lid of the krinitsa is guilty of being especially guarded, especially as it is crushed with a chavun. Great vaga virobu can cause injury.

It is necessary to air the window, and all work is allowed to be carried out only for obvious reasons for individual protection.

Behind the locker's bazhannya to the mental designation of the hatch, the name of the engineering fence (marking on the roof) can be introduced:

At- Vodoprovid;
D- Doshchova sewerage;
G, PG- fire hydrant, fire hydrant underground;
T/C- heat flow;
Before- pobutova and sewage cleaning;
HS- gas barrier;
GTS- a telephone box;
MR- main gas pipeline;
T- Telephone (telephone line);
