San JosePipe sThe concrete shall be evenly distributed, and the vibration shall be &fast inserting and slow pulling& and slightly pumping up and down to make the concrete vibrate evenly. The vibration shall be carried out in sequence to avoid over vibration and missing vibration until the concrete surface is horizontal, no significant subsidence, no bubbles and no mortar on the surface. During vibration, the vibrating handle shall not touch the side formwork, grouting pipe, pipeline embedded parts, etc.
● advantages: Simple installation, complete set; The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (it is recommended that the longest grouting outlet length should not exceed 6m); No special installation equipment is required; Grouting time can be arbitrarily selected; When grouting is carried out internally under proper pressure, the grouting pipe fluid can keep filling the whole pipe evenly; The system allows grouting under relatively low pressure; The grouting pressure is 0.2-0.4mpa.
London. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.
1 water glass grouting material water glass slurry is made of water glass as the main agent, and gelling agent is added to make it react chemically and generate a large amount of silicon gel to set and harden. Water glass paste has wide sources, low cost, low viscosity and good injectability.
.Ceramic process 1: make and process gypsum molds according to the requirements of a certain place.
In addition no environmental pollution, the water corrosion test results of the grouting material simulating the fresh water erosion environment show that the strength of the stone body of the grouting material does not lose under the condition of water corrosion for 180 days, while the strength loss of the cement water glass grouting material reaches 50%, which shows that the water corrosion resistance durability of the water glass industrial waste two liquid grouting material is better than that of the cement water glass two liquid grouting material [7].
Verify the water permeability of the rock stratum according to the measured water absorption of the borehole to determine the grouting pressure and flow, and determine the grouting slurry and its initial concentration.
The system allows grouting at relatively low pressure.
The grouting pipe is a patented product. Compared with similar products in the market,LondonLeading small catheter, it has higher tensile resistance and better sealing performance.
After the sodium hydroxide solution is poured in, the calcium chloride solution is poured in, which is called the two liquid method. Alkali solution method has the advantages of simple construction equipment, low reinforcement cost, and elimination of collapsibility of loess.
How much is it.3CaO·SiO2+nH2O→2CaO·SiO2·（n－H2O+Ca（OH）2,
The single liquid silicification method is applicable to reinforce collapsible loess with permeability coefficient of 0.1 ~ 0m/d and silty fine sand with permeability coefficient of 0.3 ~ 0m/d.
A 6-10m long orifice pipe is generally installed at the opening of the grouting hole to prevent possible hole collapse, and to play a guiding role in drilling. During grouting, it is used to install an orifice closing device to prevent grout leakage.
Grouting repair can be carried out with good repair effect. No recurrence and low cost.
reform. The grouting pipe is a thermoplastic material, which can be processed and formed many times,LondonAdvance support of small conduit, which provides convenience for the hot-melt and electric fusion connection of the pipe.
Sometimes the grouting pipe is overlaid on the two sides of the horseshoe surface. Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of grouting pipe?
The inner core of the grouting pipe is rigid, which can ensure that it will not be crushed under the concrete pressure. The non-woven filter cloth layer outside the framework only allows water and grouting fluid to pass through, and other materials such as cement slurry in concrete are blocked outside the grouting pipe to fully ensure the smooth use of the whole section of the grouting pipe. The flexibility of the product is very high, the grouting can keep filling the whole pipe evenly. The system allows grouting at relatively low pressure. The installation of grouting pipes will not affect the characteristics of the building itself. The installation or grouting process will not harm the concrete. Permanent sealing can be ensured after grouting. If there is no leakage, grouting can be omitted. The key construction process flow of grouting pipe installation is as follows: table formwork processing,LondonAdvance small conduit for tunnel, installation - grouting pipe processing - spring reinforcement framework, mesh binding - grouting pipe and installation of embedded reserved side formwork installation - process acceptance - concrete pouring - concrete curing - 10000 m3 data thickness to ensure the integrity of the table formwork, the steel plate joint weld shall be uniform.
London.Inner diameter of repetitive grouting pipe: 8mm; Outer diameter: 20mm Inner diameter tolerance: ± 0.3mm; Length of each roll: 90m.
The advantages of the grouting pipe are as follows: The embedded grouting pipe can be injected with water by on-site pressure to confirm the water tightness of the joint. Grouting is required only when the joint leaks water.
Full section slurry discharge (4 slurry discharge holes) is uniform and smooth.
