What to do when the gutter on the building meets the raft board

The building gutter is a very important part of the building, which can effectively remove the rainwater and sewage inside the building, and ensure the dryness and hygiene of the building. However, during the construction of the gutter on the building, rafts are sometimes encountered, which requires us to take some measures to solve them.

First of all, we need to understand what a raft is. A raft is a waterproofing material used in the basement or below the basement of a building to prevent groundwater infiltration. The raft is usually installed in the basement or below ground level in the basement, close to the location of the gutter, so it is easy to encounter the raft when constructing the gutter.

When encountering a raft, we need to take the following measures:

1.Adjust the position of the gutter. If the location of the gutter is close to the position of the raft, we can consider adjusting the position of the gutter slightly to avoid colliding with the raft.

2.Make special gutters. If the position of the gutter cannot be adjusted, we can consider making a special gutter with a thicker bottom of the gutter to be able to pass through the raft.

3.Install a waterproof layer. At the point where the gutter meets the raft, we need to install a layer of waterproofing material to prevent water from seeping through the gaps in the raft and into the gutter.

4.Strengthen the support of the gutter. Due to the presence of rafts, the support of the drainage ditch may be affected, so we need to strengthen the support of the drainage ditch to ensure the stability and safety of the drainage ditch.

In short, when the gutter meets the raft board on the building, we need to take corresponding measures according to the specific situation to ensure the normal use and safety of the gutter.

The raft gluten is disconnected at the gutter to make way for the gutter, but there will be a reinforcing nodal treatment diagram at the disconnection.

Is it a temporary gutter or a structural gutter?

The raft foundation should be marked with a sump. for the sump is to be sunk; The gutter may not be on the raft foundation drawing, you can see the architectural drawing; Find the location of the sump from the building drawing, and then check it on the structural drawing, and the location of the sump is also on the drainage drawing.

The construction drawings mainly represent the layout, direction and installation requirements of various equipment, pipelines and lines. Equipment construction drawings are divided into water supply and drainage construction drawings (water construction), heating construction drawings (heating construction), ventilation and air conditioning construction drawings (general construction), electrical construction drawings (electric construction), etc. Equipment construction drawings generally include floor plans, system drawings and detailed drawings.
