Is it better to harden the square first and then make a drainage ditch, or to make a linear drainage

It is best to reserve the ditch first, dig the required size, generally use the finished drainage ditch now, and then put the ditch body, cover plate, and then pave.

First dig the foundation groove, lay the trench, then lay the cover plate, and finally pave the stone.

Linear drainage ditch is a common drainage facility that can effectively collect and discharge rainwater and prevent water from soaking on the ground, thus protecting the stability and safety of the ground. For squares that need to be drained, linear gutters are a very good option. But which is better, hardening the square and then making a gutter or a linear gutter first?

First of all, if you harden the square first and then make a drainage ditch, you can ensure the stability and flatness of the square. After the square is hardened, linear gutters can be designed and installed according to the actual situation to ensure the best drainage effect. In addition, this solution also avoids damage to the plaza when installing gutters, thus reducing repair and maintenance costs.

However, if you do a linear gutter first, you can solve the drainage problem more quickly. Linear gutters can be installed early in the construction of the plaza, thus avoiding the hassle and cost of drainage treatment at a later stage. In addition, linear gutters can also play a role in draining water early in the construction of the square, thus protecting the stability and safety of the square.

To sum up, whether it is hardening the square first and then making a drainage ditch or making a linear drainage ditch first, there are advantages and disadvantages. The specific choice of which solution needs to be judged and decided according to the actual situation. Either way, it is necessary to take into account factors such as drainage effect, cost, and construction difficulty to ensure the stability and safety of the square.

If you want to build a drainage reservoir, you can use a shovel to dig it deeper to facilitate the flow of water.

Linear finished gutter installation steps and precautions Our installation instructions are commonly used installation recommendations. Any special requirements regarding the installation of gutters must be approved and confirmed by the relevant professional designer. Line.

In the drainage ditch, it is really necessary to drain the water well, otherwise it will not be easy to repair it on the road, and it will cost a lot of money, and everyone must protect the reservoir.

For the construction method of linear drainage ditch, it is necessary to select the ground of one of his drainage ditches, and then put the drainage pipe on the row.

The construction of linear drainage ditch only needs to dig a trench, put the drainage ditch into it, cut it with arc, and then pave the stone after the cover plate, which is quite convenient. For more details, please feel free to consult.

He is actually very professional in this practice, so you must find a professional maintenance master.

You'd better find relevant norms to imitate this, because you can't deal with this problem yourself, but this is a national standard.

The construction method of this drainage ditch should be directly in accordance with his intentions, and the operation steps should be some bad life in Nanjing, this girl is very not.

The width and height of the gutter design is generally as follows:

The width is generally 50cm, and the depth is 40cm

The cross-sectional size of the open ditch is generally not less than 180mm wide and 150mm deep, and the bottom of the ditch should have a longitudinal slope of not less than 1%.

Gutter Design Requirements:

The design of drainage ditch is based on the engineering layout and engineering standards of the drainage system.

The depth and spacing of drainage ditches in the field, and the flow, water level, section size and engineering quantity of drainage ditches and buildings at all levels are analyzed and calculated. The spacing and cross-sectional dimensions of the drainage ditches in the field drainage network are determined by the drainage requirements and the requirements of machine tillage. The spacing of the ditch is generally 100-400 meters.

The depth of the ditch is generally about l meters. Generally, according to the groundwater burial depth h and construction conditions required by the crop, the depth of the drainage ditch is preliminarily determined, and then the corresponding drainage ditch spacing is determined. Due to the complex hydrogeological conditions of the drainage area, the depth and spacing of the drainage ditch need to be selected through the analysis of experimental data and successful experience in similar areas.

The design flow of drainage ditch is divided into two types: drainage flow and rehearsal flow. When calculating the design flow, the design drainage modulus for these two cases is first determined (see Drainage Modulus and Drainage Flow), and then multiplied by the confluence area corresponding to the drainage ditch section respectively, which is the drainage design flow and the drainage design flow.

In general, the drainage ditch should be installed in a place that does not affect the proposed or existing buildings, as well as the material accumulation, processing and transportation, and the walking of personnel. The drainage ditch should meet the objective requirements of collecting and discharging the accumulated water on site. The longitudinal slope of the drainage ditch should be determined according to the topography and the maximum drainage volume, and the general requirements should not be less than, not less than in flat areas, and can be reduced to in swampy areas.

If the open and dark box drainage ditch is used, because it is made on site, the drainage resistance is greater than that of the cylinder tile pipe or cement pipe. Therefore, the slope of longitudinal drainage should be increased by 20% compared with the above value.

When using natural drainage ditch, the slope slope should be determined according to the quality of the soil and the depth of the drainage ditch, and in general, it can be determined that only the rock slope can be properly steepened. In order to ensure that the soil at the bottom of the natural drainage ditch is not washed away by the water flow, a layer of gravel or pebbles with a minimum thickness of 40 60 mm can be laid at the bottom of the ditch. Any form of drainage ditch should be used at the location of its outlet should be set up in a low-lying place far away from buildings and structures, and at the same time, it should be noted that measures to prevent freezing should be taken at the outlet of the drainage ditch and hidden pipe.

When the terrain and geological conditions are complex, the drainage ditch may collapse due to landslides, at this time, the design, construction, supervision and geological survey units should be invited to jointly determine the drainage plan, and then organize the implementation of the drainage ditch according to the determined plan.

Features::

1. Linear drainage ditch is a modular system with different specification groups and can cope with the needs of various building drainage, because it is linear continuous drainage, the drainage volume is better than the ordinary point drainage effect, and there will be no local water accumulation;

2. The linear drainage ditch is made of resin concrete, which has the characteristics of light weight, anti-aging, anti-frost, strong corrosion resistance, strong load-bearing capacity, smooth surface and zero permeability;

3. The unique design of the unique "U" shape can effectively increase the drainage capacity and enhance the self-cleaning function;

4. The linear design gives people a very intuitive linear appearance, which is concise and unified, and the linear continuous water interception and drainage efficiency are extremely high;

If the same ground pavement material is used in the areas of different places, then the linear drainage ditch can be used on the drainage ditch to design a unique appearance, which can be used as the dividing line of different areas and the division of the space area, so as to strengthen the sense of place in the area.

If the same ground pavement material is used in the area of different places, then the linear drainage ditch can be used on the drainage ditch to design a unique shape, and it can be used as the dividing line of different areas to divide the spatial area, so as to strengthen the sense of place in the area. Linear gutters are an improvement and upgrade of traditional gutters, which is very practical.

The Linear Drainage Ditch System is mainly used to collect urban surface water and introduce it into the municipal pipe network system.

The main material of the drainage ditch is resin concrete HDPE, which replaces the traditional methods such as bricklaying cast-in-place concrete ditch.

According to the requirements of different use environments and load-bearing requirements, Changsi drainage ditch cover is divided into four materials: HDPE, stainless steel, galvanized steel and ductile iron.

The Resin Concrete HDPE Linear Drainage Trench System has high strength, corrosion resistance, aging resistance, and is easy to install, cost-effective, and environmentally friendly compared to traditional ditches**.
