Benefits of technology

[0005]It is an object of the present invention to provide a method for levelling a basin frame, and a device especially designed for this method, which is easier and faster to perform than prior art methods.
[0009]The formwork ring may include a gasket fastened to the inner circumference of the flange. This gasket prevents casting mixture from penetrating between the formwork ring and basin frame.
[0010]Said skirt may be cylindrical. This may allow some movement between the formwork ring and the basin body.
[0011]Alternatively, the skirt may be conical. Such a design allows stacking of the formwork rings for easier transport.

Problems solved by technology

When establishing new roads, there may occur settlements in the road, the masses collapsing.
This will create a height difference between road and basin, and will also break up the asphalt bordering the basin.

Embodiment Construction

[0021]FIG. 1 shows a basin with a body 1 and top 2, which is installed in the ground. Above the ground 3 there is filled a layer of draining gravel 4. Onto the gravel 4 there is established a road with layers of asphalt 5 and substrate 6. A basin frame 7 with flange 8 and cover 9 is running through the upper layers 5 and 6. The basin frame is fastened to the upper layers, but is intended to slide freely inside the basin body 1, i.e. the basin frame is of the floating variety. This will not always work as intended, as mass will fill up to the basin frame and prevent the frame from sagging down. In case the road surface lifts, e.g. as a result of frost, a void will be formed, whereupon loads on the frame (from the traffic) will press it into the cavity and thus form unevenness between the road surface and basin frame. In this case, the basin frame has sunk and has to be elevated to come into a correct level relative to the road surface 10.

Abstract

A method is described for installing or renovating a basin in relation to a surface, wherein the basin includes at least a basin body (1) with top (2), frame (7) and cover (9), the method including lifting the basin frame from the basin body into a first position,then placing a formwork ring (11) around the basin top (2),lowering the basin frame into a second position wherein the frame is aligned on a level with said surface, the basin frame running through said formwork ring and into the basin body,injecting a casting mixture into a cavity formed between the surrounding ground and the basin frame.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a device for adjusting the elevation of a basin.BACKGROUND[0002]The expression basin includes ordinary basins for water, sewage and cables, as well as other shafts for servicing buried functions, and in particular basins that are arranged in a street, road or square, the location being covered by asphalt, concrete or pavement slabs. A basin often includes a concrete basin body which is buried in the ground and connected to pipes or tunnels. Onto the top of the basin there is ordinarily placed a basin frame holding the cover. The basin frame is made from cast iron and the frame or road is adapted to provide the top of the frame being on a level with the road. When establishing new roads, there may occur settlements in the road, the masses collapsing. The surface of the road may also elevate during winter due to frost in the upper layer, while the basin will stay put as it penetrates into the frost free subsurface. This will...
