About us
Site construction technology
Our installation instructions are commonly used. Any special requirements for installation of drainage ditches must be recognized and recognized by the relevant professional designers.1.according to the actual conditions of the installation, paving form, geological conditions, bearing grades and other specific requirements of the use of customers to choose the appropriate product type and installation location
2.adjacent surface (street, plane, etc.) should be higher than the installation height of the drainage ditch 3-5mm
3.the horizontal stress concrete area in the operation of the drainage ditch
4.when the application in the concrete arch stone section and the side surface paving, need to be embedded in the trench, or drainage ditch can effectively offset the stress
5.ensure that the drainage ditch is protected from mechanical damage during installation. For example, in the construction of vehicles must pass through the drainage ditch, should try to avoid the rolling ditch
6.grit chamber and similar falling water well is similar to the installation way of drainage ditch.
7.EN1433 mandatory provisions, can be used for the cover of the road surface level for the C250 level or above
expansion joint
When paving the way for the concrete pavement, be sure to set the same direction and the drainage ditch and vertical expansion joint. The expansion joint distance reference Haoding Huang Wei installation guide. And through the structure of the designer's approval.
If the expansion joint and the drainage ditch intersection, do not allow existing expansion joints were interrupted drainage ditch. The expansion joint is located at the junction of the two groove body, or the groove body is cut off and re sealed.
interim attachment
In the drainage ditch has been positioned and the construction has not been completed at the end of the exposure to the drain ditch At the top of the construction site is vulnerable to the destruction of traffic tools, should be avoided in the field of vehicle straight Ground roller. If the vehicle must pass through the drainage ditch, it is required to lay at least 0.9 meters wide on both sides of the ditch of the passage, do not recommend the use of active wood.
Sealing seam leakage prevention measures
If the drainage system is installed in the structure plate, the drainage ditch component can see the sealing glue in the combination part. Application of the sealant for sealing process. Sealant should be equipped with the same corrosion resistance of the drainage ditch material, but also can adapt to the movement and temperature changes from the floor. The working face in front of the sealant should be carefully treated.
Site installation procedure
1. trench excavation
The width of the ditch dug enough; at least 8cm (class A15) of the space can be used to be placed. Due to the load level and the ground of different pavement, corresponding to different size requirements. Specific reference specification can be installed Haoding Wei Huang construction and installation guide.
2. outlet arrangement
Construction is usually from the wells or other types of water intake start. When the initial position is determined, the water flow direction displayed on both sides of the channel is installed.
· Determine the position and form of the drain
· Fall well
· After determining the location and installation of the drainage ditch is correct, the connection with the municipal water wells
· According to the direction of water flow at the side of the ditch, the water inlet is arranged on both sides of the groove body, and the direction of the water flow is displayed on the side of the groove body.
3. ditch body installation
In the process of installation and concrete placement of the ditch to maintain the level and ensure the appropriate installation height. The foundation of concrete must be compacted.
A. concrete support
Attention should be avoided in the joint between the concrete and the ditch.
B. Vhbest special tools for special products
4. cover plate installation
In order to avoid the destruction of the lateral pressure in the construction of the trench wall, the cover plate should be placed in front of the ditch and the same size of the board to support the ditch.
Ensure that the drainage ditch is protected from mechanical damage during installation. For example, in the construction of vehicles must pass through the drainage ditch, should try to avoid the rolling ditch.
5. paving layer
In the laying of pavement layer adjacent the ditch body, pay attention to the lapping trench wall paving and compaction. And the completion of the pavement should be higher than the drainage ditch cover 3-5mm.
6. installation and maintenance
Prior to use need to pay attention to:
· Use water to wash the interior of the ditch.
· Clean cover plate, solid waste and waste in drains and drains
· Embedding the cover plate and fixing the system using the cover plate
system maintenance
In order to ensure that the system runs well, it is recommended to maintain the system on a regular basis.
Check contents include
1.remove cover
2.clean up the debris and debris inside the ditch, and wash the inside of the ditch with water
3.amendment of the interior of the trench and the seams
4.clean up garbage collection column and ensure that the water drain cleaning garbage.
5.drop the trash in the well.
6. re put the cover plate and fixed
