 The sound pipe produced by our company strictly complies with the standards of the Ministry of Transportation: “Steel Thin- Wall Acoustic Tubing for Concrete Filling Piles and Requirements for Use†is the national standard implementation standard “ JT/T 705-2007 â€.
     The company can also produce pre-stressed plastic corrugated pipe in strict accordance with the Ministry of Communications industry standard "plastic corrugated pipe for prestressed concrete bridge" JT / T529-2004 technical requirements for production and inspection, and meet the national standard "thermoplastic pipe ring stiffness determination More".
One: Features
Convenient operation, excellent sealing, strong tensile strength, strong torque resistance, anti-vibration, no leakage, no deformation, no blocking.
II: Installation and Usage
Installation of the lowermost section of the rebar sounding pipe: Place the A- pipe (bottom pipe with plug) on ​​the floor to check that the seal is intact. Then insert the B- tube into the A- tube until it is inserted into the bottom of the A- tube. Then tighten the screw tightly. Solid can be. After the connection is completed, the sound tube is placed in the reinforcement cage and fastened to the main reinforcement of the reinforcement cage according to the specified size. For the part without the reinforcement cage, the sound measurement tube can be fixed or reinforced with three reinforcing bars using steel reinforcement brackets. The bundling distance must not be greater than two. Meter.
Three: Advantages
1. Convenience: Easy connection of spiral sound tube, no need for on-site welding of sound tube, spiral connection, spiral double buckle, seal apron, axial end seal, effective against looseness, anti-leakage, convenient Fast, safe, and cost-effective. It takes less than 1 minute to install each connector , which saves man-hours and does not require any technical support. No need for preparation outside the site, no equipment needed, quick and easy ( 5 times faster than traditional methods ), easy fixing in reinforced cages, no bad weather
Second, economical: In the deeper construction of bored holes in bridges, the borehole infusion inspection specification requires the use of acoustic transmission method to measure the quality of the pile foundation; in accordance with the design requirements, acoustic test tubes should be buried, and common piles of 120cm-180cm pile diameter should be buried . The base needs to be embedded with three pipes. The outer diameter of 50-60mm is generally required in the conventional design, and the thickness is about 3.Omm . The use of an additional casing on-site welding is used in the construction. The cost for this method is higher. The construction cost of the acoustic pipe produced by our company only accounts for about 60 % of the construction cost of the ordinary pipe , which greatly reduces the construction cost.
Quzhou Huishida Sound Measuring Tube Factory wishes you happy every day:
This morning, when General Kim Jung-un inspected the Korean Space Agency accompanied by foreign reporters, he announced: In 10 years, North Korean astronauts should land on the sun! An American reporter asked: How do you get up when the temperature of the sun is so high? The audience was silent. Everyone does not know how to answer this question. At this time, General Kim slowly said that we are going dark! The appalling applause of the North Koreans in the audience suddenly sounded ... The Obama who was watching live on TV, smirked and said to the colleagues around: " These two forces, and there was no sun when it was dark! " There was a thunderous applause within the White House!
Ammonium Phosphate, also known as triammonium phosphate, inorganic compound, molecular formula (NH4) 3PO4, is an ammonium salt of phosphoric acid, containing anhydrous substances and hydrates. Ammonium phosphate is a colorless crystal or gray white powder, sometimes particles, soluble in water. Ammonium phosphate contains nitrogen and phosphorus. It is a compound fertilizer.
When ammonium phosphate is used as fertilizer in agriculture, special attention should be paid to its thermal decomposition and alkali decomposition. In calcareous soils with pH greater than 7.5, decomposition and volatilization of ammonia are easy to occur, and water-soluble phosphorus is transformed into citric acid-soluble phosphorus. The main chemical reactions were:
CaCO3+ (NH4) 2HPO4 - 2NH3+CaHPO4+CO2+H2O
Ammonium phosphate is a kind of high concentration and quick-acting compound fertilizer. Its content of N+P2O5 is about 64%, which is soluble in water and has a high salt index. The salt indices of monoammonium phosphate and diammonium phosphate are 30 and 34, respectively. Therefore, special attention should be paid to not contacting seeds directly when planting fertilizer, and the fertilization point should not be too close to the young roots and buds when making base fertilizer, so as to avoid the burning of ammonia released from the molecule. Ammonium phosphate can be used as base fertilizer and topdressing fertilizer, but because its molecule contains more phosphorus nutrients than nitrogen, its N:P2O5 ratio of monoammonium phosphate is about 1:5 and diammonium phosphate is about 1:2.5. In order to make the phosphorus contained in it play a full role in the early stage of crop growth, it is generally suitable to be used as base fertilizer, for those soils with higher available phosphorus or for rice. For crops with relatively less phosphorus, even as base fertilizer, a certain amount of nitrogen fertilizer should be applied to adjust the proportion of N:P2O5 to an appropriate level. Ammonium phosphate can be mixed with most fertilizers, but it should be avoided to mix with alkaline fertilizers, because it can promote the decomposition of ammonium phosphate and release ammonia.
In addition, using ammonium phosphate as raw material, a variety of compound fertilizers can also be prepared. The main varieties are: (1) ammonium thiophosphate. If the grade of ammonium thiophosphate produced by 32% monoammonium phosphate and 59% Ammonium Sulfate is 16-20-0, the product has good physical properties, the critical moisture absorption point is 75.8%, higher than that of monoammonium phosphate; 2. ammonium nitrate. The grade of representative varieties is 25-25-0, 28-14-0 and so on, which are products neutralized by mixed acid of phosphoric acid and nitric acid and ammonia; and (3) ammonium uric phosphate. This is a kind of high concentration solid compound fertilizer, which has N-P and N-P-K types, such as 28-28-0 and 22-22-11 varieties. It is generally made of ammonium phosphate slurry or granulated powder products and spraying granulated urea. The product has good physical properties and is suitable for a variety of soils and crops.
