Description

A production and construction method for backfilling caisson-type toilets

Technical field

The invention belongs to the field of backfilling of toilets, and specifically relates to a production and construction method for backfilling of caisson-type toilets.

Background technique

A caisson-type bathroom is a sunken bathroom, also called a lowered space. It means that during the main construction, the structural layer of the bathroom is partially or completely sunk from the corresponding floor to a certain height so that the horizontal drainage pipes of the bathroom are buried in it. Backfill with lightweight materials.

Common backfill methods include construction waste, slag, red brick overhead and ceramsite, but these methods all have shortcomings. Construction waste is a heavy material, and can weigh about two tons per cubic meter after absorbing water. It can easily cause the floor to be overloaded and crack. When construction waste is used for backfill, its sharp edges and corners can easily puncture the waterproof layer, causing water seepage and leakage. Difficult to repair. The slag contains a large amount of highly corrosive sulfide, which generates sulfuric acid-like compounds when exposed to water. Over time, it will corrode the upper and lower water pipes, bottom waterproofing and metal structural parts in the caisson, causing serious damage. It will corrode and age within a few years, leading to leakage in the bathroom. . Red bricks and prefabricated boards are elevated, and sewage is easy to accumulate in the space under the boards, which produces unpleasant odors over time. The space under the boards is warm in winter and cool in summer, making it a breeding ground for cockroaches and mosquitoes. In addition, scale is easy to form around the secondary drain outlet over time. Blockage, causing water to accumulate in the caisson, causing leakage in the bathroom. Ceramsite is a commonly used backfill material in mid-to-high-end decoration. However, if you follow the standard process: primary waterproofing, red brick partitioning, filling with ceramsite, laying steel bars, leveling, and secondary waterproofing, there are six steps in total, and the construction is complicated. The cost is high and time-consuming. If the standard process is not followed, the water pipes in the caisson cannot be fixed, which may easily lead to surface settlement, water leakage, odor and other defects, making maintenance difficult.

The primary sewer pipe and the secondary sewer pipe are connected to the main sewer pipe respectively, wherein the primary sewer pipe The water inlet is the toilet outlet or floor drain;.

Open a 0.2-0.7cm hole at one end of the main sewer pipe close to the reinforced concrete floor slab on the ground floor;

After plugging the holes with biodegradable plugs, pour the standard or high-density foamed cement into the pit of the caisson-type bathroom according to different room temperatures, and add the foamed cement before the foamed cement is completely solidified. The surface of the layer is pressed with a small round pipe to prepare a groove. The groove is the water inlet of the secondary drainage pipe. The degradable plug includes tuber fruits and vegetables. Before pouring the foamed cement, The pit surface of the caisson-type bathroom has been coated with waterproof material. The foamed cement is a mixture obtained by adding water, Group A, Group B, cement and Group C materials in sequence;

After the foamed cement is completely solidified, the small round pipe is removed and prepared for pressing. It is manually modified to meet the drainage requirements. Gravel that is level with the surface of the foamed cement layer is laid in the trench, and then ceramic tiles are laid on it.

In step 1), the standard version of Group A materials includes sodium lauryl sulfate, cellulose and Yuanming powder, Group B is calcium stearate, and Group C is an accelerating setting agent; the high-density version of Group A materials Including sodium lauryl sulfate, cellulose and zeolite powder, group B is calcium stearate, group C is light calcium.

Both the standard version and the high-density version are suitable for the national standards PO and PC32.5, 42.5 cement, m32.5, etc.

Calculated based on the finished product of foamed cement being 0.17 cubic meters, the proportion of the standard version of foamed cement is Group A: Group B: Group C: cement: water = 500g: 150g: 500g: 50kg: 48kg-50kg, where A The ratio of the group is sodium lauryl sulfate: cellulose: Yuanming powder = 80g: 20g: 400g.

Calculated based on the finished product of foamed cement being 0.17 cubic meters, the proportion of the high-density foamed cement is Group A: Group B: Group C: cement: water = 300g: 150g: 350g: 50kg: 48kg-50kg, where A The ratio of the group is sodium lauryl sulfate: cellulose: zeolite powder = 48g: 12g: 240g.

At different room temperatures, the standard version ratio is Group A: Group B: Group C: cement: water = 500g: 150g: 500g: 50kg: 48kg. Among them, the ratio of Group A is sodium lauryl sulfate: fiber. Element: Yuanming powder = 80g: 20g: 400g. The high-density version is used in the ratio of Group A: Group B: Group C: Cement: Water = 300g: 150g: 350g: 50kg: 48kg. Among them, the ratio of Group A is ten Sodium dialkyl sulfate: cellulose: zeolite powder = 48g: 12g: 240g. The properties of the obtained foamed cement are as shown in the following table:.

发泡水泥配比Foaming cement ratio	室温room temperature	加入水泥后温度temperature after adding cement	成品水泥性能Finished cement properties
标准版配比Standard version ratio	25℃25℃	42℃42℃	正常normal
标准版配比Standard version ratio	28℃28℃	45℃45℃	正常normal
标准版配比Standard version ratio	30℃30℃	49℃49℃	烧坏burn out
高密版配比High density version ratio	25℃25℃	35℃35℃	正常normal
高密版配比High density version ratio	30℃30℃	41℃41℃	正常normal

It can be seen that the high-density version will not cause the cement temperature to rise too high when mixing cement. If the temperature exceeds 45°C, the cement will be burned. Therefore, when the ambient temperature is lower than 28°C, use the standard version formula, otherwise, use the high-density version formula.

Under the same ambient temperature and using the high-density plate ratio of Group A: Group B: Group C: cement: water = 300g: 150g: 350g: 50kg: 48kg, using different Group A ratios, the foamed cement obtained The performance is shown in the table below:.

甲组配比Group A ratio	发泡水泥立方体抗压强度（MPa）Foamed cement cube compressive strength (MPa)	发泡水泥体积吸水率（%）Volume water absorption rate of foamed cement (%)	发泡水泥密度（kg/m ³） Foamed cement density (kg/m ³ )
十二烷基硫酸钠：纤维素：沸石粉=43g：12g：240gSodium lauryl sulfate: cellulose: zeolite powder = 43g: 12g: 240g	1.381.38	32.332.3	350350
十二烷基硫酸钠：纤维素：沸石粉=48g：12g：240gSodium lauryl sulfate: cellulose: zeolite powder = 48g: 12g: 240g	0.920.92	36.636.6	300300

It can be seen that when sodium lauryl sulfate: cellulose: zeolite powder = 48g: 12g: 240g, the number of bubbles is appropriate and the bubbles are closed. The compressive strength, volumetric water absorption and density of the obtained foamed cement are uniform. It can meet the backfill requirements of caisson bathrooms.

Please refer to Figure 1. The mixing device in step 1) includes a mixing chamber 1 and a feeding box 2; the mixing device includes a mixing chamber 1 and a feeding box 2; the main body of the mixing chamber 1 is cylindrical, and the mixing chamber 1 There is a feed port (not marked) and a discharge port, and a mixing rotor (not shown) is provided in the mixing chamber 1; the discharge port is connected to the packaging machine 10; the feed port is located at On the cylindrical warehouse wall, the feed inlet is a through hole with an inclined opening, and the inclination angle is 30-60°; the feed box 2 is a through pipe, and one end of the through pipe is provided with an extension tube wall extending outward. The extension part 3 of the through pipe is provided with a baffle 4 on the outer wall of the through pipe. The baffle 4 and the extension part 3 are located at the same end of the through pipe. When feeding materials into the mixing chamber 1, First, extend the side of the feed box 2 without the baffle 4 into the mixing chamber 1 from the feed opening, and finally the baffle 4 abuts the outside of the mixing chamber 1 . Among them, the baffle 4 can be connected to the warehouse wall through screws.

Group A materials are powder and are easy to raise dust. Furthermore, Group A materials can easily absorb moisture in the air. If too much moisture is absorbed, the material will clump and become insoluble in water, so Group A materials cannot be left exposed for a long time. Then when putting materials into the mixing bin 1, it is necessary to reduce the feed opening as much as possible.

Further, the discharge port is divided into a port 9 and b port 8, and the a port 9 is connected to the packaging machine 10; the mixing chamber 1 is also provided with a through hole (not labeled), and the The through hole is connected to the b port 8 through the pipe 6; an exhaust fan (not shown) is provided inside the pipe 6 near the through hole, and a removable fan is provided at the connection between the pipe 6 and the b port 8. The dehumidification box 7 contains dehumidifier. In the actual production process, because there are many mixed materials in the mixing bin 1, but the packaged quantities are small, the packaging time is longer. During this process, sodium lauryl sulfate easily absorbs water, agglomerates, and becomes insoluble in water. Thus it becomes ineffective when foaming. By setting up an exhaust fan, the air in the mixing chamber 1 is led to the dehumidification box 7 through the pipe 6. After being dehumidified by the dehumidification box 7, it returns to the mixing chamber 1. Then the humidity in the mixing chamber 1 is reduced to ensure the stability of sodium lauryl sulfate. quality. Among them, the dehumidifier in the dehumidification box 7 can be replaced at any time.

Specifically, a hygrometer is provided inside the pipe 6 near the through hole. The hygrometer is electrically connected to the exhaust fan. When the humidity tested by the hygrometer is higher than the first set value, the exhaust fan starts. When the humidity is lower than the second set value When , the exhaust fan is turned off, where the first set value is greater than the second set value. It should be noted that when the exhaust fan is started, no material is put into the mixing chamber 1, and the feed port is blocked with a plug to ensure the internal circulation of air in the mixing chamber 1. When materials are put into the mixing chamber 1, the plug is blocked at port b 8, so that the mixed material falls into the packaging machine 10 from port a 9.

Furthermore, the mixing device also includes a dust removal device 5 , which is connected with the mixing chamber 1 .

In step 2), the degradable plug is selected from tubers and fruits and vegetables.

Please refer to Figure 2. The grooves include a first water diversion ditch 16, a second water diversion ditch 15 and a water catchment tank 14. The first water diversion ditch 16 is formed by opening trenches from the four corners of the surface of the foamed cement layer to the water catchment tank 14. The second water diversion ditch 15 is formed by opening a ditch from the edge of the surface of the foamed cement layer to the first water diversion ditch 16 or the water collection tank 14. The water tank 14 is the water inlet of the secondary drainage pipe. Furthermore, the depths of the first water diversion ditch 16 and the second water diversion ditch 15 change from shallow to deep from the circumferential direction of the surface of the foamed cement layer toward the water collecting tank 14 . This facilitates rapid introduction of ceramic tile surface water into the sink 14. During the specific construction, before the foamed cement dries, a squat toilet membrane is placed in the foamed cement layer. After the foamed cement solidifies, the squat toilet membrane is taken out. There is a drainage pipe embedded in the position of the squat toilet membrane.

In this application, a tertiary drainage structure is used to ensure that the bathroom does not leak. Specifically, a waterproof layer is not coated between the foamed cement layer and the ceramic tiles. Part of the water on the surface of the bathroom tiles is discharged from the primary drainage pipe through the floor drain, and the other part is discharged from the primary drainage pipe through the floor drain. The ceramic tiles leak down to the foamed cement layer, and then reach the sink 14 along the water diversion ditch, and are discharged through the second drainage pipe. In the event that water leaks through the foamed cement layer to the bottom layer, the water will pass through the holes decomposed by the degradable plugs. It is discharged from the main sewer pipe to ensure that the bathroom does not leak.

The equipment used for stirring during backfill construction includes a mixing motor, a mixing barrel and a mixing assembly. The mixing barrel has a two-section structure, including an upper straight section and an inverted cone section at the bottom, where the straight section is a circular shape with an open top. The top opening of the barrel is fixed with a stirring motor through a motor mounting base, the inverted cone section is docked with the bottom of the straight barrel section, and a discharge pipe is provided at the bottom of the barrel of the inverted cone section; the stirring assembly includes a stirring shaft, A first stirring plate, a second stirring plate and a plurality of stirring blades.
