Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a building pool plastering construction and a full water test method therefor. Background Art

[0002] With the continuous development of society and the steady improvement of people's living standards, people's requirements for the quality of life are getting higher and higher. Buildings are closely related to all aspects of people's lives. Therefore, the demand for high-quality buildings in the construction market is increasing, and low-quality buildings are gradually being phased out by the market. In the actual construction process of building projects, there are many construction processes for concrete, and the construction process is relatively complex. However, as the basic material for project construction, whether the construction technology is professional will directly affect the quality of building projects. In the entire process of concrete construction, construction management personnel with relatively high technical levels are required to control the entire construction process in order to effectively improve some common problems existing in the concrete construction process, thereby ensuring the smooth construction of building concrete construction projects. At present, most of the construction methods for building pools are not standardized and the waterproof effect after construction is poor. In view of the above problems, a building pool plastering construction and a full water test method therefor are specifically proposed. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above existing deficiencies and provide a building pool plastering construction and a full water test method therefor.

[0006] S2, repairing and cleaning the base layer;

[0007] S3, filling putty and plastering the waterproof coating on the inner wall of the pool;

[0008] S4, detecting the full water condition of the pool;

[0009] S5, full water test detection of the pool: The specific operation steps of the full water test detection of the pool in step S5 are as follows:

[0010] S51, preparation matters before detection;

[0011] S52, filling water into the pool;

[0012] S53, observing the water level of the pool;

[0013] S54, measuring the evaporation amount of the pool;

[0014] S55, calculating the water seepage amount of the water level.

[0015] Preferably, the specific operation steps of troweling the ground base layer in step S1 are as follows:

[0016] For the first troweling, gently trowel the surface layer with a steel trowel to flatten the footprints.

[0017] For the second troweling, when the surface layer begins to set and there are footprints on the ground surface layer but it does not sink, use a steel trowel for the second troweling. At this time, pay attention not to miss any troweling and flatten the pits, sand holes and footprints on the surface layer.

[0018] For the third troweling, when there are slightly footprints on the ground surface layer and no trowel marks appear during troweling, use a steel trowel for the third troweling. At this time, apply a little more force during troweling to smooth and polish the trowel marks. The time for polishing should be controlled to be completed before final setting.

[0019] Preferably, the specific operation steps of base layer repair and cleaning in step S2 are as follows:

[0020] S21, Repair:

[0021] Hollow drum: All hollow drums in the base layer should be removed and the base layer should be redone.

[0022] Cracks: Repair small cracks with putty and polish them flat with cement sandpaper after drying; for large cracks, a waterproof layer can be made after cleaning and then fill with cement mortar.

[0023] Holes: Level the holes less than 3mm on the surface of the base layer with polymer cement putty, and repair the holes larger than 3mm with cement mortar.

[0024] S22, Cleaning:

[0025] Clean the mortar, dust, mildew, grease, etc. on the surface of the base layer.

[0026] Preferably, the specific operation steps of filling putty and painting the waterproof coating on the inner wall of the pool in step S3 are as follows:

[0027] Partially apply putty: Select putty with good quality. During construction, it is advisable to apply it thinly rather than thickly.

[0028] Grind flat: First use a grinding machine or coarse sandpaper for grinding during polishing, and then use fine sandpaper for grinding; in order not to affect the operation, grinding should be carried out after the base surface or putty is dry.

[0029] Apply putty: Apply putty with even force, master the inclination of the tool, and ensure that the putty is evenly filled.

[0030] For exterior wall coating construction, it is not advisable to apply putty in a large area, and the putty layer should not be too thick. The material used is polymer cement putty.

[0031] The paint is applied by first applying a primer coat and then two topcoat layers. The number of topcoat layers can be increased according to the project quality requirements. The painting construction is carried out from top to bottom, and each coat should be bounded by dividing lines, walls, and the intersections of internal and external corners.

[0032] Preferably, the specific operation steps for the detection of the full water condition of the pool in step S4 are as follows:

[0033] Detect that the compressive strength of the concrete of the pool structure, the impermeability grade, or the strength of the cement mortar of brick or stone masonry pools meets the design requirements;

[0034] Detect that the waterproof layer construction of the cast-in-place reinforced concrete pool, the external anti-corrosion layer construction of the pool, and the backfilling construction outside the pool meet the requirements;

[0035] Detect that the installation of the inlet, outlet, drain, overflow, and connecting pipes and the stuffing of the pipe openings passing through the wall are all completed;

[0036] Detect that the anti-floating stability of the pool meets the design requirements.

[0037] Preferably, the specific operation steps for the preparation before detection in step S51 are as follows:

[0038] Repair the defects of the pool concrete: The treatment of local honeycombing, pockmarks, holes, shrinkage cracks, temperature cracks and other defects is completed;

[0039] Inspect the pool structure: Check whether there are deformation cracks, cracking, and uneven settlement in the pool. If there are the above situations, it should be processed after being appraised by relevant departments such as the design department;

[0040] Check the temporary plugs and gate valves, and there should be no leakage;

[0041] Clean the sundries in the pool;

[0042] The water injected should be clean water, and the preparation work for the water injection and drainage pipeline system should be done well;

[0043] The ventilation holes and manhole covers on the top of the pool should be installed: The necessary safety protection facilities and lighting should meet the test requirements;

[0044] Install a water level observation scale on the inner wall of the pool, mark the highest water level of the pool, install a water level gauge, and also prepare an evaporation water tank for the open pool. The evaporation water tank is made of DN500 steel pipe, 300mm high, sealed with steel plate at the bottom, and a water level gauge is installed on the open mouth. The water tank should be inspected and there should be no leakage. The water tank should be fixed in the pool, and the water filling depth in the water tank is about 200mm. While measuring the water level in the pool, measure the water level in the water tank.

[0045] Preferably, the specific operation steps for the water injection of the pool in step S52 are as follows:

[0046] The water injection into the pool should be carried out in three times, with the water injection volume each time being 1 / 3 of the designed water depth. The rising speed of the water injection level should not exceed 2m / 24h, and the interval time between two adjacent water filling should be no less than 24h, so that the concrete can fully absorb water, which is beneficial to the healing of micro-cracks in the concrete;

[0047] After each water injection, it is advisable to measure the water level drop value for 24h. At the same time, the filling quality of the concrete of the external structure of the pool body and the through-wall pipes should be carefully checked;

[0048] If there is leakage on the concrete surface of the outer wall of the pool and the pipe filling, and the measured water seepage volume during the water level drop is relatively large, the water injection should be stopped. After inspection, analysis and treatment, the water injection can be continued;

[0049] Even if the water level drop (water leakage volume) meets the standard requirements, as long as there are signs of leakage on the outer surface of the pool wall, the concrete is considered not to meet the specification requirements.

[0050] Preferably, the specific operation steps of the water level observation of the pool in step S53 are as follows:

[0051] The water level during water injection is observed with a water level scale;

[0052] When measuring the water seepage volume after the water injection reaches the designed depth, a water level gauge should be used to measure the water level. The reading accuracy of the water level gauge is 0.1mm. The water level gauge is generally fixed on the square timber. For the capped pool, the square timber is generally fixed at the manhole, and for the open pool, it can be fixed with the embedded parts on the pool wall;

[0053] After 24h when the water level in the pool reaches the designed depth after water injection, start to measure the reading of the water level gauge;

[0054] The time interval between the final reading and the initial reading of the water level measurement should be no less than 24h;

[0055] The measurement time of the water level drop in the pool can be determined according to the actual situation. If there is no leakage on the appearance of the pool and the water seepage volume meets the standard, it can be measured for another day; if the previous water seepage volume exceeds the allowable water seepage volume standard, the water level drop can be continuously measured and the extended measurement time should be recorded. At the same time, find out the reason for the water level drop exceeding the standard until a reasonable solution is made.

[0056] Preferably, the specific operation steps of the evaporation measurement of the pool in step S54 are as follows:

[0057] For the full water test of the covered pool, the evaporation can be ignored;

[0058] For the full water test of the uncovered pool, while measuring the water level in the pool, measure the water level in the evaporation water tank.

[0059] Preferably, the specific calculation method of the water seepage volume in step S55 is as follows: The water seepage volume of the pool is calculated according to the following formula:

[0060] q = A1[(E1 - E2) - (e1 - e2)] / A2;

[0061] Where: q ---- seepage water volume (L / (m2·d));

[0062] A1 ---- water surface area of the pool (m2);

[0063] A2 ---- total wetted area of the pool (m2), that is, the wetted area of the pool bottom and the inner pool wall, and the partition wall is not counted;

[0064] E1 ---- initial reading of the water level gauge in the pool, that is, the initial reading (mm);

[0065] E2 ---- final reading of the water level gauge in the pool 24 hours after reading E1, that is, the final reading (mm);

[0066] e1 ---- reading of the water level gauge in the water tank when reading E1 (mm);

[0067] e2 ---- reading of the water level gauge in the water tank when reading E2 (mm).

For an open pool, an evaporation water tank is also required. The evaporation water tank is made of DN500 steel pipe, 300mm high, and sealed with a steel plate. A water level probe is installed on the open mouth. The water tank should be inspected for leakage. The water tank should be fixed in the pool, and the water depth in the water tank should be about 200mm. When measuring the water level in the pool, the water level in the water tank should be measured at the same time.

7. A construction pool painting construction and full water test method according to claim 1, characterized in that: The specific operation steps of the step S52 of injecting water into the pool are: Water should be injected into the pool three times, with the amount of water injected each time being 1 / 3 of the designed water depth. The water level rise rate should not exceed 2m / 24h. The interval between two adjacent water fillings should be no less than 24h, so that the concrete can fully absorb water and is conducive to the healing of concrete micro cracks. After each water injection, the water level drop value should be measured for 24 hours. At the same time, the filling quality of the concrete structure of the pool body and the wall-penetrating pipes should be carefully checked; If there is leakage on the concrete surface of the pool body and the pipe filling, and the water level drops and the measured water seepage is large, water injection should be stopped, and water injection can be continued after inspection, analysis and treatment; Even if the water level drop (leakage) meets the standard requirements, as long as there are signs of leakage on the surface of the pool wall, the concrete is considered to not meet the standard requirements.

8. A construction pool painting construction and full water test method according to claim 1, characterized in that: The specific operation steps of the water level observation in step S53 are as follows: The water level during water injection is observed using a level gauge; When water is injected to the designed depth for water seepage measurement, the water level should be measured with a water level probe. The reading accuracy of the water level probe is 0.1mm. The water level probe is usually fixed on the beam. The beam of the capped pool is usually fixed at the manhole. The open pool can be fixed with embedded parts on the pool wall. 24 hours after the water level in the pool is filled to the designed depth, start measuring the reading of the water level probe; The time interval between the final and initial readings of the water level should be no less than 24 hours; The time for measuring the water level drop in the pool can be determined according to the actual situation. If there is no leakage on the outside of the pool and the water seepage volume meets the standard, the measurement can be continued for one day; if the water seepage volume last time exceeds the allowable water seepage volume standard, the water level drop can be measured and recorded, and the extended measurement time can be recorded. At the same time, find out the reason why the water level drop exceeds the standard until a reasonable solution is found.

9. A construction pool painting construction and full water test method according to claim 1, characterized in that: The specific operation steps of step S54 for measuring the evaporation amount of the water pool are as follows: In the full water test of a covered pool, the evaporation can be ignored; The full water test of the uncovered water pool measures the water level in the evaporation water tank at the same time as the water level in the pool.

10. A construction pool painting construction and full water test method according to claim 1, characterized in that: The specific calculation method of the water level seepage calculation in step S55 is: the water seepage in the pool is calculated according to the following formula: q = A1[(E1-E2)-(e1-e2)] / A2; Where: q----water seepage (L / (m2.d)); A1----water surface area of ​​the pool (m2); A2----The total wetted area of ​​the pool (m2), i.e. the wetted area of ​​the pool bottom and inner pool wall, excluding partition walls; E1----The initial reading of the water level probe in the pool, i.e. the initial reading (mm); E2----The reading at the end of the water level measuring needle in the pool 24 hours after E1, i.e. the final reading (mm); e1----the reading of the water level probe in the water tank when measuring E1 (mm); e2----The reading of the water level measuring needle in the water tank when measuring E2 (mm).
