PREPARATION FOR THE INSTALLATION[\/vc_custom_heading][vc_empty_space empty_h=&#8221;1&#8243;][vc_column_text]Technical evaluation of the sewer<\/p>\n<p>Before the rehabilitation the pipe is jet-cleaned with a sewer cleaning machine placed on a truck. After that the pipeline is inspected with a remote-controlled camera. The analysis of the video from the sewer inspection forms the basis to create a detailed computer report on the technical condition of the pipe. On the basis of report data the sewer is classified depending on its technical condition.<\/p>\n<p>SELECTING THE REHABILITATION METHOD<\/p>\n<p>Depending on how the sewer is damaged or destroyed and its classification to a specific group, depending on its technical condition an appropriate rehabilitation method is selected. After the evaluation of the sewer\u2019s technical condition one should analyze geodetic data, groundwater level with respect to the base of the sewer, road traffic exposure, and other parameters that have influence on the selection of parameters of the liner that is to be used.<\/p>\n<p>Storage and transportation to the construction site<\/p>\n<p>The liner is delivered in bags or bulk to a stacking yard (warehouse) and from there it is delivered to the construction site in appropriate batches.[\/vc_column_text][vc_custom_heading text_size=&#8221;h4&#8243; text_weight=&#8221;300&#8243; text_color=&#8221;accent&#8221;]4. LINER INSTALLATION[\/vc_custom_heading][vc_empty_space empty_h=&#8221;1&#8243;][vc_column_text]The order of works of placing the appropriate layer of chemical resistant mineral surface is as follows:<\/p>\n<p>Sewer cleaning from any existing small and large debris using a jetting truck (10-20 MPa) and manual cleaning of rubble and stones.<br \/>\nHigh-velocity water jetting (70-100 MPa) of the walls and ceiling of the sewer to dislodge any corroded loose sewer structure fragments and remove fats and other fixed foreign matter.<br \/>\nPreparing the walls and ceiling for the application of the mineral layer \u2013 removal of dripstone, leaks and unevenness using additional materials (quick-curing mortars, tack coats and injection grouts).<br \/>\nSpraying a mineral layer onto the wet surface of the sewer using a screw pump. In the case of brick sewers two layers are sprayed. The first layer is to fill the joints between the bricks and identify any missed minor leaks which must be removed before the application of the second layer. The optimal layer thickness is 10 mm, and if multiple layers are applied the thickness must not exceed 25 mm.<br \/>\nDrying the sewer by putting by-passes and connections. A by-pass can be made inside the sewer and then the flow is driven entirely by gravity, or outside using sewage pumps of a capacity of up to 1,200 m3\/h.<br \/>\nCleaning sewer floor using a jetting truck.<br \/>\nHydrojetting or wet sandblasting the sewer floor.<br \/>\nPreparing sewer floor for the application of a mineral layer using additional materials.<br \/>\nSpraying a mineral layer or applying it by hand (egg-shaped sewers).<br \/>\nBy-pass removal and minor corrections after removing external by-pass.<br \/>\nThe sewer is usable after ca. 8 hours from the final application of the layer.<br \/>\n[\/vc_column_text][vc_custom_heading text_size=&#8221;h4&#8243; text_weight=&#8221;300&#8243; text_color=&#8221;accent&#8221;]5.
