  2. Diamond grinding of pavement - Wikipedia

    en.wikipedia.org/wiki/Diamond_grinding_of_pavement

    Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt concrete pavements. Most often utilized on concrete pavement, diamond grinding is typically performed in conjunction with other concrete pavement preservation (CPP) techniques such as road slab stabilization, full- and partial-depth repair, dowel bar retrofit ...

  3. Concrete pavement restoration - Wikipedia

    en.wikipedia.org/wiki/Concrete_Pavement_Restoration

    A recent study was conducted that shows that diamond grinding is an effective means of extending the service life of concrete by imparting a smooth pavement surface with desirable surface texture. The process can also be used to address faulting at joints or cracks, roughness, polished concrete surfaces exhibiting inadequate macrotexture, wheel ...

  4. Pressure sewer - Wikipedia

    en.wikipedia.org/wiki/Pressure_sewer

    In a typical set-up, a receiving well is provided close to the properties being served so that all sewage can gravitate to the well. An electric macerator pump (also called a grinder pump) pumps the finely macerated sewage through a narrow diameter continuous plastic pipe which discharges into the nearest gravity sewer or treatment plant.

  5. Pavement milling - Wikipedia

    en.wikipedia.org/wiki/Pavement_milling

    Micro milling is also known as carbide grinding. It is a lower cost alternative to diamond grinding of pavement. [2] Micro milling uses a specialty drum with three to four times as many cutting teeth than a standard milling drum. [12] Micro milling can be used either as the final surface [13] or as a treatment before applying a thin overlay. [12]

    The concrete floor of the manhole has channels to minimize accumulation of solids. Interior of a large sanitary sewer viewed from an access manhole chamber. In the developed world, sewers are pipes from buildings to one or more levels of larger underground trunk mains, which transport the sewage to sewage treatment facilities.

    To install this, the doghouse manhole is lowered to have the two openings to slide over the existing pipe. The concrete is poured in to form the base with slopes from the precast concrete wall down to the half point of the existing pipe. This forms a half bench for the manhole base. The top half of that existing pipe is cut open to form a channel.

    Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain, [1] surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...

  9. Grinder pump - Wikipedia

    en.wikipedia.org/wiki/Grinder_pump

    Grinder pumps can be installed in the basement or in the yard. If installed in the yard, the holding tank must be buried deep enough that the pump and sewage pipes are below the frost line. A grinder pump is different from a sump pump or effluent pump. There are two types of grinder pumps, semi-positive displacement (SPD) and centrifugal.
