Application objects of Drainage Board Drainage Storage Board Chen
The application scope of Drainage Board Drainage Storage Board can be roughly divided into several types
Garden Engineering Garage Roof Greening , roof garden, football field, golf course, bathing project
Municipal engineering road subgrade, subway tunnel
Construction engineering building foundation upper or lower floor, basement internal and external walls, roof anti-seepage and heat insulation layer, etc.< br/> Traffic engineering highways, railway subgrades, dams and slope protection layers
Construction conditions of geotechnical plastic drainage boards
The construction process of geotechnical plastic drainage boards is relatively complex, and the following is a brief introduction
Materials and Machinery
Plastic drainage board (Chen product specifications select the type and model according to the design requirements and construction technical conditions).
The main construction equipment for installing drainage boards (including guide frames, casings, vibrating hammers that drive the casings to sink, winches, drums for installing drainage boards, and windproof devices) can also be used. A crane pile driver can also be used to replace the working device with a simple plate inserter.
Industrial conditions
In the technical preparation before construction, determine the layout and construction of drainage holes according to the foundation design requirements and topographic and geological conditions. The order of inserting drainage boards.
The construction site and roads must meet the requirements for installing drainage boards, such as the entry and exit of construction personnel and machinery, the arrangement of temporary facilities (including water, electricity, communications, etc.).
According to construction After laying out the location of the drainage holes determined by the organization design, use bamboo sticks as marks to determine the location of the holes.
It has the operating conditions for blowing and filling.
The difference between drainage boards and drainage boards
The material can store water, but the board cannot. The water storage capacity of the centimeter-height drainage board per square meter is about kilograms.
The drainage effect of the sheet is good, and the drainage effect of the coil is slightly inferior. Assuming a large amount of rainwater, First of all, you must consider using sheet materials. In addition, roof garden sheets are often used.
Rolled materials can prevent root thorns, while old sheets cannot prevent root thorns. Rolled materials can also play a certain role in waterproofing. Rolled material construction It is fast, and one worker can lay about one square meter per day. The construction difficulty alone is more difficult than that of sheets. Sheet materials are simple to construct, just splice the materials together directly. But the construction alone is slow, and one worker can lay about one square meter per day. If roll materials are used , the material cost of the rolled material is slightly higher than that of the sheet material. Because when laying the rolled material, a supporting grid is needed to prevent the geotextile from being sunken and affecting the drainage effect when backfilling the soil. Today, Chen will talk about what Plastic drainage board, taken out of context, is a drainage board made of plastic. Drainage board is mainly used in engineering and soft soil engineering. There are water belt type, harmonica shape, and wave shape. The skeleton of the drainage board is made of plastic. , relatively light, and anti-corrosion. Some buildings are constructed on soft soil foundations for insert construction. They are mainly inserted on the foundation to set off the sand and clay to make the foundation flexible and consolidate the soft foundation, thus increasing the construction speed. For deep and heavy projects, When the soft soil foundation is reinforced by the drainage consolidation method, technical and economic considerations should be considered,
