How to deal with puddles on concrete pavement?

If there is a puddle on the concrete pavement, it is to take a shovel to lift it out or use a water pump to pump it out, and then you can hit the concrete when it is dry. Otherwise, no.

The concrete pavement has been rolled by many vehicles, there will be some potholes, and then it will accumulate water when it rains, and it must be filled in time, otherwise, it will penetrate downward, and then the range will become larger and larger.

There are puddles on the concrete pavement, in this case, the puddles should be carefully cleaned first, without leaving dust impurities, and then the low-lying area should be re-smoothed with cement.

If there are puddles on the concrete pavement, it is common to use the same proportion of concrete to rehabilitate the pavement.

The problems on the road surface and bridge deck are comprehensive and diverse, and it is also inevitable, and understanding the problems is the key to solving the disease. The key to the maintenance of pavement decks is to find the internal causes

1. Urban roads.

The drainage system is unreasonable, and the maintenance is not in place for a long time. For cement concrete roads such as pavements and bridge decks, the first problem to consider is to solve the problem of drainage. If the drainage system is not always handled well, a large amount of stagnant water cannot be discharged inside the road surface, which will inevitably cause water seepage on the road surface and subsidence of the roadbed.

Many roads are caused by rain and sprinkler trucks, causing the roadbed to sink and water to the outside. As a result, there were large-scale collapses and fractures, and then the problems were serious.

Second, the original pavement bridge deck design is unreasonable. Cement concrete roads are mostly paved with cement, stone, sand and other materials. But if there is no thoughtful consideration at the beginning of the design, coupled with the reason of the mix ratio during construction, the material above is not strong and nothing to make up, so whether it is the roadbed treatment when the new road is repaired, or the disease problem due to the road surface in the later stage, the repair material can only be used for surface work, and the roadbed will be twice the result with half the effort, sometimes the load pressure of the vehicle after the water immersion occurs, and soon the pavement bridge deck will form mud, causing the bottom of the roadbed plate to be hollowed out, resulting in uneven local stress on the road, causing road surface damage.

Third, the construction problem, in many cases, because of the problem of construction operation, some construction teams have not done road repair construction, before this, the construction workers have never been in contact with this project, no work experience. On the surface, it is qualified, and the people and materials that can be used are not qualified, which is a problem caused by human factors, and we still take the interests of the country as the advance condition when selecting the construction team.

If the concrete floor is uneven and there is water accumulation, the following methods can be considered:

Topping: Concrete is added to uneven ground to make it level.

Drainage: Install drainage pipes or gutters to divert water down the drain.

If the unevenness of the concrete floor is severe, a full reconstruction may be required. Before choosing a treatment method, it is advisable to consult a professional or have an experienced contractor evaluate it.

Pour another layer of concrete with concrete,Artificially looking for slopes, pure laughterFind the low place high, and the water will flow naturally to the lower place.

Finish. But the bottom must be cleaned, if it is not burned, it will leave the shell, and there will be water in the cracks. Ascending.

Pro, the uneven water collapse of the concrete ground is treated as follows: 1. After the concrete pavement potholes rain, there will be rainwater accumulation in the pavement potholes, we can use the pumping machine to pump out the water at the pavement puddles, or use the cutting machine to cut the seams on the pavement, bury the drainage pipe to lead the stagnant water to the nearby rainwater and so on. 2. After the concrete pavement is cleaned up, we need to repair the potholes on the pavement.

We first cleaned up the damaged concrete blocks, leaves and other debris in the potholes on the pavement. Then according to the product instructions, the concrete repair material is configured and stirred evenly. The concrete repair timber is then poured into the pit and compacted and smoothed with a tool such as a spatula.

After the concrete mass is repaired, we also need to carry out sprinkler maintenance, and finally we use a grinder to polish the pavement repair.

According to the Code for the Design of Outdoor Drainage

The municipal drainage department defines the water accumulation point as: when the rainfall exceeds 50 mm in 24 hours, the meteorological department Wu Yu issued a blue warning for heavy rain.

The depth of water accumulation on the road is up to 15 cm, the water receding time is up to 1 hour, and the water accumulation area is greater than 50 square meters.

Mild water accumulation: The average depth of water accumulation in the road section is equal to 15 cm, the water accumulation time is up to 1 hour, and the water accumulation area is greater than 50 square meters and less than or equal to 300 square meters.

Sewage pumping stations and pressure pipes.

In the pipeline system, it is often necessary to lift the sewage at the low place upward, which suddenly needs to set up a pumping station, which is located in the middle of the pipeline system and is called the middle pumping station, and the pumping station located at the end of the pipeline system is called the terminal pumping station. When the sewage needs to be transported by pressure after the pumping station, a pressure pipeline should be installed.

Sewage treatment plants.

Urban sewage treatment plant is an important part of urban construction and an indispensable public facility for urban production and people's life.

The task of the treatment plant is to conscientiously implement the policy of serving production and people's lives.

Municipal Sewage Drainage System:

Municipal sewage drainage systems are usually used to collect and drain domestic sewage.

for the main drainage system.

1) Indoor drainage system and equipment. Indoor sanitary appliances (such as toilets, sewage pools, washbasins, etc.) and drainage equipment in the production workshop play a role in collecting sewage and wastewater, and they are the beginning of the entire drainage system. Domestic sewage and industrial wastewater flow into the sewage pipe system of the block (factory, neighborhood or courtyard) through the indoor sewage pipe system such as water seal pipes, branch pipes, risers, main pipes and outlet pipes laid indoors.

2) Outdoor sewage drainage system. The outdoor sewage drainage system mainly includes the block sewage drainage system and the street sewage drainage system.

Dear, hello, I am happy to serve you, the answer is as follows: How to deal with the water on the concrete floor? If the land area is treated with water trenching, the concrete floor is treated with a cutting machine and the potato surface is treated with a cutting machine from the brick joint. The best thing to do is to do it all over again.

Fill the road section, the higher ground can be opened to make a rapid flow channel drainage. If it is at the lowest point and there is no place to drain the water, the only way to do this is to add a rainwater inlet and bury a drainage pipe to direct the water out, or to the rainwater well near the section of the attached bench.

The concrete floor is uneven and there is water that needs to be smoothed, and the concrete cannot be rained before the concrete is finally set. The main reason is that rainwater erosion leads to the loss of cement, fly ash and other cementitious materials inside the concrete.

The main phenomenon is the sand on the outside of the concrete. After the concrete is poured, it should be covered with a waterproof tarpaulin. It is not only the appearance quality that affects the concrete, but also the thickness of the concrete structure.

A two-meter ruler is used to take carpet measurements. That is, at least the same position is measured in the direction of the crossing, if there is a gap of more than 3 mm or even 5 mm under the ruler. This indicates that the ground is uneven. It has exceeded the requirements for the paving of wooden floors.

It depends on what you want to achieve, to what extent it is uneven, and to what level you want to achieve, generally it is to do leveling or grinding!

If the land area is treated with water trenching, the concrete floor is treated with a cutting machine and grooved, and the floor tile floor is treated with a cutting machine from the brick joint. The best thing to do is to do it all over again.

Fill the road section, the higher ground can be opened to make a rapid flow channel drainage. If it is at the lowest point and there is no place to drain the water, the only way to do this is to add a stormwater inlet and bury a drainage pipe to divert the water or to a nearby rainwater well.

The ground is first chiseled, and then a layer of 1:2 glued mortar is smeared.
