Method for eliminating floor'pot cover effect 'accumulated water

Abstract

The invention discloses a method for eliminating'pot cover effect 'accumulated water on a floor, which relates to the technical field of geotechnical engineering, and comprises the following steps: fully paving capillary water guide geotextile on an indoor concrete floor with a certain area, placing lime bags with proper sizes at the opposite angles of the capillary water guide geotextile, and forming holes capable of being opened and closed in the floor corresponding to the lime bags. The reason of'pot-cover effect 'water accumulation of the floor is that the upper floor prevents evaporation of'pot-cover effect' water on the concrete floor, so that surface accumulated water cannot be discharged, and a series of healthy environment problems are caused. Therefore, according to the method for eliminating the pot cover effect accumulated water of the floor, the accumulated water is dredged to the lime bag through the capillary water guide geotextile by utilizing the high suction force difference between the lime bag and the accumulated water on the ground, so that the problem of the pot cover effect accumulated water of the floor is solved.

Description

Technical Field

[0001] The invention relates to the technical field of geotechnical engineering, and in particular to a method for eliminating water accumulation caused by a "pot cover effect" on a floor. Background Art

[0002] The "pot lid effect" is a phenomenon in which water vapor in unsaturated soil or in the external atmosphere migrates from warm areas to cold areas under the drive of temperature gradient, and condenses into water or sublimates into ice under a closed cover layer, resulting in an increase in the moisture content of shallow soil (including the surface). In actual engineering analysis, the problem of ground water accumulation under the indoor floor of a building caused by the migration of water vapor due to the "pot lid effect" has a significant impact on people's living environment and physical and mental health. Timely elimination of indoor ground water accumulation is the key to preventing the deterioration of the indoor environment and ensuring the quality of the building.

[0003] In some areas, indoor floor decoration usually chooses to lay elevated wooden floors. However, after investigation, it was found that there is usually water accumulation and mold on the concrete floor under the floor, and this problem is relatively hidden and difficult to be discovered, which will affect people's living environment. After consulting the literature and analyzing it, the reason for the accumulation of water is that the hot and humid water vapor condenses into water when it contacts the relatively low temperature concrete floor. As time goes by, the water content of the ground continues to increase. At the same time, the closed floor hinders the evaporation of the accumulated water, making it impossible to drain the accumulated water on the ground. This is called the "pot lid effect" of the floor. Usually, the only way to solve this problem is to pry the floor open to eliminate the accumulated water and clean the floor. This construction method has the disadvantages of high cost and inconvenient operation.

[0004] Therefore, it is necessary to provide a method for eliminating the water accumulation of the "pot cover effect" on the floor to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a method for eliminating water accumulation due to the "pot cover effect" on the floor, which effectively utilizes the material properties of the lime bag, such as the extremely strong water absorption, and the capillary geotextile, such as the extremely strong hydrophobicity, to eliminate water accumulation due to the "pot cover effect" on the floor, and solve the problem of living health environment caused by water accumulation on the indoor floor.

[0006] To achieve the above object, the present invention provides a method for eliminating water accumulation due to the "pot cover effect" on the floor, comprising the following steps:

[0007] S1: Clean the local unit construction concrete floor and lay the capillary water-conducting geotextile on the floor;

[0008] S2: The size of the capillary geotextile is larger than the ground size. The capillary geotextile covers the junction of the ground and the wall, and the folding height is not less than 5 cm from the wall to the ground;

[0009] S3: A lime bag is set at the diagonal of the capillary geotextile, the lime bag is close to the capillary geotextile, and the folding height of the capillary geotextile at the diagonal of the lime bag is not less than the height of the lime bag; a high suction area is formed between the lime bag and the water on the concrete floor;

[0010] S4: Laying the floor on the capillary geotextile, with floor opening and closing holes corresponding to the positions of the lime bags opened on the floor, and the diameter of the floor opening and closing holes is the same as the maximum dimensions of the length, width and height of the lime bags;

[0011] S5: The cut floor is placed into the floor opening and closing hole, and the floor opening and closing hole is closed.

[0012] Preferably, the thickness of the capillary geotextile in step S1 is set to be no less than 0.3 cm.

[0013] Preferably, the length, width and height of the lime bag are set to 25 cm, 20 cm and 10 cm respectively, and the floor opening and closing hole is set to be circular.

[0014] Therefore, the present invention adopts the above-mentioned method for eliminating water accumulation in the "pot cover effect" of the floor, which has the following beneficial effects:

[0015] (1) The lime of the present invention is easy to obtain, and the lime bag can be easily replaced through the floor opening and closing hole after the water absorption capacity becomes weak.

[0016] (2) The capillary geotextile used in the present invention has good hydrophobic properties and does not occupy the effective use space of the building.

[0017] (3) The present invention utilizes the high suction difference between the lime bag and the ground water, and guides the accumulated water to the lime bag through the capillary geotextile, thereby eliminating the problem of water accumulation on the floor due to the "pot cover effect", with low construction cost and strong applicability.

[0032] Example

[0033] Construction was carried out on the local concrete floor of 3m×7m to remove the "pot cover effect" water accumulation;

[0034] Step S1, clean the local construction concrete floor 2 with a size of 3m×7m, ensure that the floor 2 is dry and free of foreign matter, and fully spread the capillary water-conducting geotextile 4 on the floor 2, and the thickness of the capillary water-conducting geotextile 4 is set to 0.3cm;

[0035] Step S2, use the special glue for capillary geotextile to smear the ground 2, keep the capillary geotextile 4 firmly attached to the ground 2, avoid wrinkles and damage, and keep the surface of the capillary geotextile 4 flat. The capillary geotextile 4 covers the junction between the ground 2 and the wall. When encountering a corner, the geotextile should be turned up by at least 5cm and firmly attached to the wall;

[0036] Step S3, placing lime bags 3 at one of the diagonals of the capillary geotextile 4 plane, and setting the folding height of the capillary geotextile 4 at the diagonals of the lime bags 3 to be not less than the height of the lime bags 3; the length of the lime bag 3 is set to 25 cm, the width is set to 20 cm, and the height is set to 10 cm. The bag wrapped with lime has the characteristics of water permeability and air permeability, the lime bag 3 is filled with dry lime, and the special glue for the capillary geotextile is used to make the lime bag 3 and the capillary geotextile 4 close together; a high suction area 5 is formed between the lime bag 3 and the water on the concrete floor, and the water on the concrete floor is absorbed by the lime in the lime bag 3 along the water flow direction 7.

[0037] Step S4, then laying the elevated floor 2 above the capillary geotextile 4, and operating in accordance with the specification during the laying process to prevent damage to the capillary geotextile 4, when the floor 2 is laid to the lime bag 3, a circular floor opening and closing hole 1 is left above the lime bag 3 corresponding to the floor 2;

[0038] Step S5: Use a cutting machine to open a circular floor opening and closing hole 1 with a diameter of 25 cm. The floor opening and closing hole 1 can be opened or closed as needed, so as to facilitate the replacement of the failed lime bag. The above operation steps can be flexibly arranged according to the actual room opening depth.

[0039] Therefore, the present invention adopts the above-mentioned method of eliminating the "pot cover effect" water accumulation on the floor, and cleverly utilizes the high suction difference between the lime material and the ground water accumulation and the extremely strong hydrophobic property of the capillary geotextile to achieve the effect of eliminating hidden water accumulation on the concrete floor.
