Abstract

The block comprises empty pipes and several chambers. The lowest chamber (4) is used for water and is filled with insulating material. The energy supply block is installed in a supply trench with a sand covering (5). The first chamber (6) is used for post and electricity, with the second chamber (7) being used for gas, and a free pipe for a further utility. A third chamber (8) is used for water piping, and an intermediate insert (9) or separating plate separates the individual elements in the block.

Description

Traditional way

When supplying houses, a pipe trench is usually first with a Depth from 1.40 m to 1.60 m and a width of 0.80 m (according to UVV with Formwork) to lay the water pipe. Then the trench becomes partial backfilled. The gas line can then be laid; the excavation is after Laying back filled. Electricity and postal lines are usually on one another route next door. In the property is the same and several times dug up different places to relocate all the necessary divisions. This repeated excavations on different routes set a multiple Measure the utilities ahead. The trenches in the same place can usually do not remain open until the installation is complete because others This would hinder and endanger construction companies. It is in the construction industry impossible that all companies have their pipes and tubes on the same day Laying lines (mutual disability, scheduling difficulties, etc.).

Through repeated measurements, excavation and a larger excavation volume there are much higher costs!

Description of the power supply block

An energy supply block is used to supply energy to civil engineering houses. This energy supply block can be used from the property boundary. In one block, all divisions (post office, electricity, water and gas) become one House run. There is still room for a further supplier, as this is his product (e.g. Cable television) through an integrated conduit in the block. Of the Energy supply block is installed together with the water laying. He can also be relocated by sewer construction, however this should be done by responsible site manager. This means measuring once and a dig for all utilities in the property that are outside the Property.

All lines can be replaced without digging in the property (e.g. at Defects). They are loosened in the house and pulled outside (with gas inside). The block is laid with a cover of 0.65 m and has a depth of 0.55 m, which means an excavation of 1.25 m with a sand sole of 0.05 m. The width of 0.30 m requires a pipe trench width of 0.40 m to 0.50 m, which with a Pounder can be compacted or washed in. The one below The water pipe is insulated, making excavation of 1.25 m sufficient. By this shallow depth means that no formwork is necessary. The length of the blocks should be at 5.0 m so that they remain easily transportable. The block can be on any  required dimension can be easily cut to size. The cut ends then you only have to use a special one that is already on the market Sealant be sprayed waterproof. The empty pipes will face the house sealed gas and watertight.

There are different ways to connect several blocks together: e.g. U-pieces, half shells, rubber sleeves, flexible hoses, etc. The water is connected with insulated shells. Angles are also possible by two blocks can be connected with flexible pipes or blocks with one finished Angle of 30 °, 45 ° and 90 ° can be used.

The remaining free interior of the block is made with recycled materials, Styrofoam, sealing foam or similar that can be cut and flame retardant (e.g. for Cable fire) Material filled out.

The casing (outer body) of the block is made of plastic just like that Intermediate plates in the power supply block. The empty pipes for electricity and post are PVC pipes with a diameter of 0.075 m (75 mm), for the gas pipe is as Empty pipe requires a PVC pipe with a diameter of 0.085 m (85 mm) and for the water pipe as an empty pipe is a PVC pipe with a diameter of 0.110 m (110 mm) provided. An additional PVC pipe with a diameter of 0.075 m (75 mm) is also installed for another supplier.

The three divisions into which the power supply block is divided are: corresponding colors marked from the outside (electricity, post green, gas = yellow and water = blue). All utilities are in the block from damage protected later construction and excavation work. In addition, a route line with the inscription "Attention energy supply block!" attached over the block. Fire protection (already on the market) is planned in the wall entries. The Materials of the pipelines to be laid are mostly made of PE pipes for water Gas PE-HD and steel and for post and electricity cable lines. But it can also other materials are used. When winding steel pipes is one further excavation pit necessary. The dimensions of water and gas can be different (Nominal size) DN 25 to DN 65 can be introduced into the block. Superstructures of the block with z. B. garage, carport, greenhouse or similar is possible, since the lines are easily exchangeable from outside at any time and none Development must be demolished. Even when crossing streets for house connections the power supply block can be used; the road only needs to be dug up once and the suppliers can subsequently dig into the Insert block. The power supply block could also be larger Dimensions are produced, with larger lines then being carried out could become (e.g. large companies or similar).

Advantages of the power supply block

• - All supply lines in one block
• - Short construction times for all sectors
• - Due to the spacing of the cables in the block there is no "up and in front of the house shut down "the supplier needed
• - The property is used in a space-saving manner (all are 0.30 m wide Pension providers)
• - All supply carriers are in the plastic-encased block Damage protected (dredging work!)  
• - Easy and quick installation of the supply carriers
• - The customer receives a cost-effective package with all utilities
• - One-time measurement and excavation of the pipe trench route in the property (inexpensive!)
• - No formwork according to UVV at a depth of 1.25 m (inexpensive!)
• - The lines are also in the power supply block when filling and Compacting protected
• - manageability of the few material parts; better protected against theft
• - Since the block can also be manufactured with angled angles of 30 °, 45 ° and 90 ° assembly (turning left and right) is easier.

The invention is explained on the basis of several drawings:

The plastic block ( 1 ) with the PVC empty pipes ( 2 ) is shown in the drawings (figures). The first two chambers ( 3 ) are filled with polystyrene, recycling material, assembly foam or the like. The lowest chamber ( 4 ) for water is filled with insulating material. The energy supply block is provided with a sand covering ( 5 ) in the supply trench. The first chamber ( 6 ) contains mail and electricity; in the second chamber ( 7 ) gas and an empty conduit for another supplier; the third chamber ( 8 ) contains the pipe for the water supply. The intermediate inserts ( 9 ) (dividing plates) separate the individual divisions in the block. In a house 20 m from the property boundary, four energy supply blocks ( 10 ) are laid. All energy sources ( 11 ) can be brought in from the outside from the property boundary ( 15 ) (water ( 12 ), gas ( 13 ), post and electricity ( 14 )). It can also be used with angled power supply blocks ( 16 ) z. B. with 30 °, 45 ° and 90 °.

Claims (1)

Common division of property on the property to supply houses. Civil engineering work for gas, water, electricity and post connections is already underway partly in a common pipe trench (dimensions: 0.80 m wide, 1.40 m-1.60 m deep). The problem is that from a depth of 1.25 m according to UVV the Pipe trench must be boarded up (higher costs!) And that several Construction site appointments are necessary to achieve the joint laying (coordinate the respective divisions and providers in the same period and in a trench extremely difficult). In between, the ditch is partially restored filled with a handicap of the construction site operation and an increased accident risk to exclude. The possibility of laying empty pipes requires an even bigger one Pipe trenching for all sectors. So far there have been longer assembly times and a longer one Machine use necessary for a joint division relocation, characterized, that all sectors (gas, water, post and electricity) in one power supply block can be relocated. The dimensions of the plastic block (width 0.30 cm, height 0.55 m, Length 5.0 m) and the excavation depth of only 1.25 m (water pipe is in the block isolated) enable cheaper and easier handling: it must no longer be peeled and there is no repeated measuring and digging necessary in the property. Thanks to the empty pipes integrated in the block, the Supply providers gradually from outside the property line at any time Insert your carrier pipe (or pull it out for repair work). Thanks to the unique low excavation, short assembly time and short The power supply block offers optimal conditions for machine use a cost-effective solution for the customer in the future Europe-wide energy market to be able to offer a compact energy package in a block system for civil engineering.
