3 advantages: Simple installation,South BostonPile bottom grouting pipe,South BostonLeading small conduit42, 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; four
South Boston.The bi-directional tensile plastic mesh false roof used in underground coal mine with mine grouting pipe is specially designed and manufactured for the false roof support of underground coal mining face and roadway wall support. It is made of several high molecular polymers and filled with other modifiers through heating, extrusion, molding, punching, shaping, coiling and other processes. Compared with metal textile mesh and plastic woven mesh, it has light weight, high strength, isotropy, and antistatic, It is a new type of mesh grouting pipe material for underground coal mine support engineering and civil engineering.
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.
. Special slings shall be used for lifting horizontal components such as laminated plates, and the stress of each lifting point shall be uniform to avoid fracture due to uneven stress of components. Grouting method is a method of injecting some curable grout into the cracks or pores of rock and soil foundation to improve its physical and mechanical properties. The purpose of grouting is to prevent seepage, stop leakage, reinforce and correct the deviation of buildings.The grouting mechanism includes filling grouting, seepage grouting, compaction grouting and split grouting. Grouting materials include granular slurry and chemical slurry. Granular slurry is mainly cement slurry. Chemical slurry includes silicate (water glass) and polymer slurry. Silicification method, alkali solution method, polymer chemical grouting method and cement grouting method.
The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed. Product advantages: Simple installation, complete set. No special installation equipment is required, and the cut-off length can be prepared on the construction site according to the actual requirements of the joint (it is recommended that the longest grouting outlet length should not exceed 6m). The grouting time can be arbitrarily selected.
Provide considerate service, solve customer problems, and realize one-stop procurement.
The reusable grouting pipe is used for waterproof sealing of concrete joints and can be used for multiple times of grouting.
The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted which is caused by the Chengdu grouting pipe manufacturer's failure to smooth (flatten) the grouting pipe along the horseshoe surface.
Injecting grout into the embedded grouting pipe can seal construction joints, cold joints pipe leakage and joints between the ground walls.
Word of mouth recommendation.The grout stop plug grouting method is generally used for Rock Fissure Grouting. The grouting pipe is provided with a grout stop plug, which can close the upper part of the grouting section. The main construction steps are as follows: the rotary drill is generally used for drilling the grouting hole. All grouting holes in the rock stratum are required to be cored for drilling, so as to find out the development and distribution of fractures in the rock stratum. The coring rate should reach 80-90% in hard rock stratum and 70% in broken rock stratum. The drilling cleaning fluid is mainly clean water. If the rock is broken and the hole collapses seriously, the mud slurry can also be used as the circulating fluid.
[Patent Description] fast cutting device in the hole of underground grouting pipe [technical field] [0001] the utility model relates to a device for cutting grouting pipe in a coal mine, in particular to a fast cutting device in the hole of underground grouting pipe.
● specification: inner diameter of disposable grouting pipe: 8mm; Outer diameter: 12mm; Inner diameter tolerance: ± 0.3mm; Length of each roll: 120m.
2 the particle size of cement clay paste clay is generally very small (less than 0.005mm), the specific surface area is large, and it has colloidal chemical characteristics when encountering water. The characteristic of clay minerals is that their atoms are arranged in layers, and different arrangements form different clay minerals, the most common being kaolinite,South BostonSelf propelled hollow grouting anchor manufacturer, and the transverse overlapping width shall not be less than 15cm. The former shall be placed on the latter according to the asphalt paving direction. After laying the glass fiber grouting pipe, fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of 30mm, 30mm and a thickness of 0.3mm. The fixed spacing can be determined according to the actual construction situation.
Reusable grouting pipe: it can be used for many times and the grouting is not limited by time.
South Boston.4 ultra fine cement slurry and cement grouting materials have been applied since 1838 in Thomson tunnel, it has been found that ordinary cement has a large particle size and limited permeability England. In practice, which can only penetrate into cracks and pores larger than 0.1 mm, while the grouting effect for micro cracks is poor. In order to improve the injectability of cement slurry in low permeability media, ultra-fine cement grouting materials have become a research hotspot at home and abroad. As early as the early 1970s, Japan took the lead in developing ultra-fine cement grouting materials, and the United States and Russia also successfully developed this product [3].
The grouting water ratio of grouting construction is 0.6:1 ~ 0.5:1 (i.e. the weight ratio of water and cement), and the principle of &dilute first and then dense& is adopted. Po45r early strength Portland cement is used as the cement. Before mixing the cement slurry, the quality of the cement shall be checked. If it is found that the cement is hardened and deteriorated or fails the test, it shall be discarded to prevent the quality of pile end grouting from being affected by the deteriorated cement. The grouting time should be 5-7 days and 15-18 days after the completion of single bearing platform pile construction.
If there is no leakage, grouting can be avoided; Common specifications ccll-y series grouting pipe: grouting once, non reusable ccll-d series grouting pipe: multiple grouting, grouting is not limited by time.It is applicable to waterproof joints of subway, tunnel and basement. If there is water leakage, grouting can be omitted. Grouting pipe is a kind of embedded grouting pipe system, cold joints, pipe seepage joints and gaps between ground walls in concrete. It is very suitable to install grouting pipes between the joints of new and old concrete. When water penetrates into the joint, the joint can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be made into durable seals by this method.
