Description
Technical Field
The invention relates to a paving method of an outdoor hardening site, in particular to a paving method for reducing rainwater runoff of the outdoor hardening site.
Background
The outdoor hardening field of the small building room in the city, the outdoor public square and the like are the main fields for providing outdoor activities and exercising body of people. However, water accumulation in the sections is serious every time of heavy rain, and the phenomenon of waterlogging in building districts and outdoor public squares is common. The reason is that the indoor and outdoor hardened sites of the building districts occupy a certain proportion, the runoff coefficient is large, and the water-discharging capacity of a rainwater pipe network is exceeded quickly in the heavy rainfall period, so that the runoff time generated on the ground surface is short in the heavy rainfall period, and the waterlogging of the building districts is caused.
Disclosure of Invention
The invention aims to provide a paving method for reducing rainwater runoff in an outdoor hardened field, which can reduce rainwater runoff superposition in rainstorm seasons and relieve urban waterlogging.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention relates to a paving method for reducing rainwater runoff of an outdoor hardened field, which comprises the following steps:
step 1, excavating a foundation in an outdoor site needing hardening according to a set depth, and tamping the foundation to form a plain soil foundation;
Optionally, in step 1, the set excavation depth principle is: the excavation depth is less than the various pipeline burying depths of the lower part of the outdoor hardening site, so that the normal use of various pipelines is not influenced in the construction process, and the excavation construction is simpler.
Optionally, in step 2, the thickness of the laid plain concrete cushion layer is more than or equal to 100mm, so as to prevent the buttress from settling.
Optionally, in the step 4, a gap reserved between adjacent reinforced concrete tongue-and-groove building blocks is 10 mm; the joint caulking by the fine stones can offset the influence of expansion with heat and contraction with cold, and can play a role of water passing in rainy season.
The advantages of the invention are embodied in the following aspects:
1. in rainstorm seasons, rainwater falling on an outdoor hardening site is converged into an overhead space at the lower part of the concrete rabbet building block through the water holes; it can be seen that the rainfall of tens of millimeters or hundreds of millimeters can be completely consumed on the spot without being discharged outside.
2. When the hardened site outside the existing building small room is reformed, the influence on the daily life of residents is very limited. From the beginning of paying off and excavating, foundation treatment (tamping) at the lower part of the buttress, buttress building, tongue-and-groove block paving and the like, the construction process is very simple, and the construction speed is high. Even if the individual tongue-and-groove paving building blocks are uneven due to construction reasons or buttress settlement, the maintenance is easier.
3. Compared with common pavement bricks, water permeable bricks and stone pavements on the street, the rabbet building block is relatively heavy in weight, and four corners of the rabbet building block are supported by the brick-built buttresses, so that the phenomena of loosening, breaking and the like which are common in the pavement of the street are not easy to occur.
4. When the outdoor hardening site area is large, the construction can be carried out in batches, and the recovery can be carried out while the construction is carried out.
5. The excavation depth is shallow, and various pipelines at the lower part of the hardening site outside the small building room cannot be influenced.
6. When the building blocks are paved, a gap of 10mm is reserved, the influence of expansion with heat and contraction with cold can be offset, meanwhile, the gap is embedded by fine stones, and the effect of water passing can be achieved in rainy seasons.
7. After the device is used for some years, some tongue-and-groove building blocks can be lifted, the silting condition of the lower part is checked, and necessary cleaning and maintenance are carried out according to the needs. Compared with the existing permeable asphalt, permeable concrete and permeable brick ground, the method can recover the rainwater runoff control function through the cleaning and maintenance mode.
8. In summer, in order to prevent the breeding of mosquitoes and flies, a plurality of drugs for killing mosquitoes and flies can be regularly sprayed downwards through the water through holes on the rabbet building blocks.
9. The rainwater runoff reducing and rapid reconstruction method is suitable for rapid reconstruction of rainwater runoff reduction of hardened sites outside existing building districts, and has certain practical significance for newly built building districts, schools, hospitals and other sites.
10. The height of the brick buttress can be combined with the actual situation of the area, and the area with small rainfall capacity is lower than a certain point; in areas with large rainfall, the height is higher than a certain point; according to the actual situation, the conditions are adjusted according to the local conditions.
11. When the tongue-and-groove building blocks are prefabricated, corresponding surface patterns can be designed when a mould is manufactured according to use requirements, and a flexible landscape effect can be created after paving.

As shown in figure 1, the paving method for reducing the rainwater runoff of the outdoor hardened field adopts the reinforced concrete rabbet building block 1 to pave, and the reinforced concrete rabbet building block 1 can be prefabricated in a factory or on the spot, and is recommended to be prefabricated in the factory, so that the paving method is favorable for ensuring the quality. The specification of the tongue-and-groove building block can be set to various specifications such as 500mm multiplied by 1000mm, 1000mm multiplied by 1000mm, 100mm multiplied by 1500mm, 1500mm multiplied by 2000mm, 2000mm multiplied by 2000mm and the like; the condition of the grade and the reinforcing bars of the concrete can be determined by calculation according to the use characteristics of the outdoor hardening field. In order to meet the requirement of water passing, when the rabbet building block is prefabricated, water passing holes 2 with the diameter of 20, 25 or 30 are reserved on the rabbet building block, and the number of the water passing holes 2 is determined according to a rainfall test in local rainstorm seasons.
The paving steps are as follows:
step 1, after paying off an outdoor field needing hardening, excavating a foundation according to a set depth;
beneficially or exemplarily, the excavation depth is smaller than the burying depth of various pipelines at the lower part of an outdoor site needing hardening, so that the normal use of various pipelines is not influenced in the construction process, and the excavation construction is simpler; then, tamping the excavated foundation to form a plain soil foundation 3;
and 2, paving a plain concrete cushion layer 4 with the thickness of more than or equal to 100mm on the plain soil foundation 3 at the preset buttress position to prevent the buttress from settling. Then, building a buttress 5 on the plain concrete cushion layer 4;
advantageously or exemplarily, the buttress 5 is a brick-laid buttress, the buttress height H can be selected to be 120mm, 180mm or 240mm, etc., but must meet the modulus requirements of the brick; the selection of the height H of the buttress mainly considers that the requirement of water storage capacity is met, a certain overhead space is built at the lower part of a hardening surface layer, and the reduction of rainwater runoff in a rainstorm period is inevitably facilitated;
