San JosePipe sPush the rock powder and sundries that have not been washed, remain at the bottom of the hole, or stick to the hole wall beyond the grouting range, so as to improve the bonding strength and impermeability of the slurry stone body and the fissure surface.
Grouting time can be arbitrarily selected; When grouting is carried out internally under the action of appropriate 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.
Saguenay .The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip, anchor plate, anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.
Flexibility: it is convenient to place at the corner without cutting and connecting.
.● specification: inner diameter of disposable grouting pipe: 8mm; Outer diameter: 12mm; Inner diameter tolerance: ± 0.3mm; Length of each roll: 120m.
(outer diameter - wall thickness) what is actually obtained is the average value of the inner and outer diameters of the circumference. If this value is multiplied by the circumference ratio (π = 141592, the circumference will be obtained. If the circumference is multiplied by the wall thickness, the area of a section will be obtained. If the area of this section is multiplied by 1 meter (1000mm), the weight of one meter length will be obtained.
Classified according to the movement mode of grout in the stratum Filling grouting: filling large cracks and caves with grout is called filling grouting.
The comparison between the embedded detection and the on-site detection of the grouting pipe is yzed as follows: The embedded detection pipe: The pile diameter of 0.6 ~ 0.8m should be buried with double pipes; Three pipes shall be buried with pile diameter of 0.8 ~ 0m; Four pipes shall be buried above the pile diameter of 0m. According to the specific situation of Chifeng bridge, three pipes can be buried in the pile foundation.
Causes of wrinkling: the blanking specification of pipe joint is too long.
The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way.
Where is good.Reusable grouting pipe: it can be used for many times, and the grouting is not limited by time.
When the a diameter of grouting connecting reinforcement is less than or equal to 16, the a diameter of connecting reinforcement is greater than
How to connect the grouting water stop needle and the grouting pipe after the grouting water stop needle and the grouting pipe are connected, a set of grouting system will be formed. As long as the small part of the grouting needle is inserted into the joint of the lotus petal grouting pipe, a closed and self-locking grouting system will be formed.
The grouting pipe has good air tightness, low gas permeability, strong sealing and no leakage.
Discount. Flexibility: it is convenient to place at the corner without cutting and connecting.
In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole, the resistance of Jiangsu acoustic pipe will appear in the process of application and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction,Saguenay Support advance small conduit, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application,Saguenay Hollow self-propelled anchor rod manufacturer,Saguenay 22hollow composite anchor manufacturer, because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period, and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, and there is a concave appearance on the adjacent side. This kind of wrinkle is mostly in the shape of sharp ridges, some of which are straight to the nozzle, and often occur symmetrically at both ends of the center line, in the shape of &eight&. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, and some occur on the outer arc surface.
The grouting pipe is a thermoplastic material, which can be processed and formed many times, which provides convenience for the hot-melt and electric fusion connection of the pipe.
Saguenay . Select appropriate transmission voltage and amplifier gain and keep them unchanged during retest.
● 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.
Push the rock powder and sundries that have not been washed remain at the bottom of the hole, or stick to the hole wall beyond the grouting range, so as to improve the bonding strength and impermeability of the slurry stone body and the fissure surface.
