Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a basement drainage board and drainage ditch. Background Technology

[0002] With the rapid development of the construction industry, underground space is being continuously exploited, leading to an increasing number of water leaks in underground engineering projects. These serious leaks not only affect people's normal use of basements, but also cause steel bar deformation or corrosion, seriously endangering building safety and requiring attention.

[0003] Based on existing technological findings:

[0004] Among the existing water seepage phenomena, the causes of leakage are varied. Some difficult leakage problems cannot be properly handled in a short time, which affects the normal progress of subsequent construction processes. After the subsequent construction processes are completed, the repair costs are high and it is difficult to completely cure the problem. Leakage of raft slabs in multi-story basements is common. It is necessary to carry out anti-leakage treatment on locations that are prone to leakage, such as post-pouring strips, dewatering wells, and embedded parts of lattice columns. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a basement drainage board and drainage ditch. The drainage board is pre-laid before basement floor construction. Based on the location of the sump, the basement is divided into several areas, and the drainage ditch locations are rationally arranged to ensure smooth drainage in each area. The full coverage of the drainage board on the basement floor serves to guide leakage later. A 75mm PVC pipe is cut into three sections and arranged in an arch shape. After installation, it is filled with mortar, and then high-strength expansion concrete is poured on top. This construction method can prevent the risk of leakage affecting the structural surface layer later, and serves to guide leakage. In case of leakage later, water flows along the drainage board to open and closed ditches, and then from the open and closed ditches to the sump. It is safe, reliable, simple to construct, and inexpensive.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a basement drainage board and drainage ditch, including a base plate, a wall panel fixed on the upper side of the base plate, and a basement floor poured on the upper side of the base plate, and further including: multiple drainage board bodies and a collection well, the multiple drainage board bodies being laid between the base plate and the basement floor; the collection well being located at one end of one of the drainage board bodies; multiple open drainage ditches and concealed drainage ditches are equally spaced and staggered on the inner side of the multiple drainage board bodies, PVC pipes are installed on the inner side of each of the multiple open drainage ditches, and the junctions of the multiple open drainage ditches and concealed drainage ditches are wrapped with mesh cloth.

[0007] In some embodiments, multiple PVC pipes at the junctions of the open drainage ditches and the concealed drainage ditch are disconnected, and grates are provided on the sides.

[0008] In some embodiments, multiple PVC pipes are each divided into three sections from a single piece, with two ends removed to form an arch.

[0009] In some embodiments, the junctions of the multiple hydrophobic plate bodies are fixed to the raft plate with steel nails.

[0010] In some embodiments, the junctions of the multiple drainage ditches are wrapped with mesh cloth and then filled with mortar.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] This invention involves pre-laying a drainage board before basement floor construction. Based on the location of the sump, the basement is divided into several areas, and the locations of the drainage ditches are rationally arranged to ensure smooth drainage in each area. The full coverage of the basement floor with the drainage board serves to guide leakage later. A 75mm PVC pipe is cut into three parts and arranged in an arch shape. After the arrangement is completed, it is filled with mortar, and high-strength expansion concrete is poured on top. This construction method can prevent the risk of leakage affecting the structural surface layer later and serves to guide leakage. In the event of leakage later, the water flows along the drainage board to open and closed ditches, and then from the open and closed ditches to the sump. It is safe, reliable, simple to construct, and inexpensive.

[0013] This solves the existing problem of leakage risk in the later stage of floor surface layer. Attached Figure Description

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved basement drainage board and drainage ditch. The technical solution of this utility model is as follows:

[0024] like Figures 1-5 As shown, a basement drainage board and drainage ditch includes a base slab 1, a wall panel 2 fixed to the upper side of the base slab 1, and a basement floor 3 poured on the upper side of the base slab 1. It also includes multiple drainage board bodies 4 and a collection well 5. The multiple drainage board bodies 4 are laid between the base slab 1 and the basement floor 3. By laying multiple drainage board bodies 4, it serves to divert future leaks. The collection well 5 is located at one end of one of the drainage board bodies 4. Multiple open drainage ditches 6 and closed drainage board ditches 7 are equally spaced and staggered on the inner sides of the multiple drainage board bodies 4. PVC pipes 8 are installed on the inner side of each open ditch 6, and the junction of multiple open ditch 6 and underground drainage board ditch 7 is wrapped with mesh cloth 9. By wrapping with mesh cloth 9, clogging of PVC pipes 8 is effectively avoided. If leakage occurs in the raft later, the leaked water will flow from the lower part of multiple drainage board bodies 4 to multiple open ditch 6, or from the lower part of multiple drainage board bodies 4 to multiple underground drainage board ditch 7, then to multiple open ditch 6, and finally to the collection well 5, so as to ensure that there is no water accumulation on the ground surface.

[0025] like Figure 5 As shown, in one embodiment, multiple PVC pipes 8 at the junction of multiple open drainage ditches 6 and underground drainage ditch 7 are disconnected, and grates 10 are provided on the side to prevent garbage from entering and clogging the underground pipes.

[0026] like Figure 3 As shown, in one embodiment, multiple PVC pipes 8 are each divided into three sections from a single piece, with both ends removed to form an arch shape, ensuring the drainage effect.

[0027] like Figure 1 As shown, in one embodiment, in order to ensure the installation effect of multiple hydrophobic plate bodies 4, the joint parts of the multiple hydrophobic plate bodies 4 are fixed to the raft plate with steel nails.

[0028] like Figure 4 As shown, in one embodiment, the junctions of multiple open drainage ditches 6 are wrapped with mesh cloth 9 and then filled with mortar.

[0029] The specific working method is as follows: Based on the location of the water collection well 5, design and draw the locations of multiple open drainage ditches 6 and concealed drainage ditch 7. Pre-cast and fix the multiple open drainage ditches 6 and concealed drainage ditch 7 according to the drawing locations. Except for the locations of the multiple open drainage ditches 6 and concealed drainage ditch 7, fully cover the remaining areas with drainage board bodies 4. Fix the joints to the raft slab with steel nails. Pour the basement floor 3. After the concrete reaches its strength, remove the formwork from the ditch. After removal, clean the debris from the ditch, taking care not to push the debris under the multiple drainage board bodies 4. Cut the 75mm PVC pipe 8 into three sections vertically, remove two sections and insert them into the ditch, forming an arch shape to drain accumulated water. Fill the top with mortar and pour the top... Concrete can be poured, using high-strength micro-expansion concrete. Multiple drainage board culverts 7 require buried pipes. The junctions are usually set along one direction and disconnected in the other. The junctions are wrapped with mesh cloth 9 and then filled with mortar to prevent blockage of PVC pipes 8. At the junctions of multiple water collection ditches 6 and drainage board culverts 7, the buried pipes in the culverts are disconnected, and grates 10 are installed on the sides to prevent garbage from entering and clogging the pipes. If leakage occurs in the raft slab later, the leaked water will flow from the lower part of the multiple drainage board bodies 4 to the multiple water collection ditches 6, or from the lower part of the multiple drainage board bodies 4 to the multiple drainage board culverts 7, then to the multiple water collection ditches 6, and finally to the collection well 5, to ensure that there is no water accumulation on the floor surface.

[0030] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
