Our company specializes in plugging technology: "Polymer grouting grouting waterproof plugging technology." My company uses a professional waterproof anti-corrosion materials manufacturers and a number of national research institutions for many years developed techniques to a variety of imported chemical materials, according to the construction of water pressure is almost the size of the ratio of the viscosity of water into the same liquid, permeability, inject 0.1 mm slit in the concrete under pressure and very humid environment quickly gather. Setting time can be accurately controlled with the ratio within a few seconds or a few minutes in the water speed of pressure, rapid condensation of water flow and more cases. Good permeability, shrinkage after swelling with water, insoluble in water, kerosene, gasoline and other organic solvents, acid, alkali, bacteria erosion will also affect post from atmospheric conditions, there is a certain strength, elasticity and transformer, Shelf use more than a decade. Tensile strength, Construction had been plugging the crack mouth, and later appeared normal settlement or dislocation cracks also no leakage. The key is to waterproof plugging cracks leak handling, according to the degree of structural causes and effects of cracks occurring, etc., the company is a primary plugging operations qualified construction enterprises, the company has a number of well-trained rising block Drain operations technicians and other professional and technical personnel, all operating personnel certificates. The company does not take years of using scaffolding, aerial work non-stop to ensure the safety of construction, civil construction, for owners of units to cut costs. Companies in strict accordance with the technical requirements and specifications plugging construction drawings and feed, in strict accordance with the provisions of the Production Safety Law to regulate the construction and civil construction team, in terms of quality, safety and civil construction industry units to produce a satisfactory answer . Hangzhou Metro Line 1 ***** plugging the main structure of a construction plan, prepared on the basis of 1: site conditions and material properties, scope of application. 2: "building waterproof engineering point of order" DBJ15-19-97 3: "building construction and acceptance of" 4: "underground waterproof engineering technical specifications" GB50108-2001 5: "underground waterproof engineering Quality Acceptance" GB50208-2002 6 : ******** structural design drawings 7: design requirements and the relevant provisions of two Project Overview ******** Hangzhou Metro, Line transfer station at the same site, including the main structure of the station and five entrances, station total length of 161.75m, the standard segment of the total width of the station 36.6m. Wulin Square underground station at the southern end of the commercial development of structures affected by the underground storey development, line depth is large, the station floor depth of about 26.4m. Standard segment of three underground stations across five island platform structure, the effective width of the largest platform for 29.3m, overburden roof approximately 4.0m. Four five underground stations across both ends of the structure, roof casing approximately 1.5m. 1200mm thick envelope station using underground continuous wall, standard wall segments and end well deep 45.5m, standard segment, end fittings are made of cross-well plate joints, brushing crystalline waterproofing cement walls and lining the wall between successive underground walls lined with concrete walls and intensity level are C30, impermeability grade P10. In addition to the station roof has several leaks focus, the rest mainly sidewall construction joints, cracks and vertical sidewall leakage caused by surface Honeycomb. Third, the leakage cause analysis according to the status of water leakage into the following four cases for analysis. 1, Pock formation Honeycomb cellular leaking concrete directly related. The main reason is leakage or vibration during the construction period and occurred less vibration, this Honeycomb in a concrete structure, some independent existence, while others were coherent. Therefore, in the event of seepage, leakage performance when seepage into pieces, drain or into shares of leakage phenomenon. 2, when the old and new concrete joints (construction joints) water leakage in the original concrete structure continues to pour concrete, the original surface of the concrete foundation no cutting hair treatment or after cutting hair is not clean or not rinse, poured concrete mixture on the original concrete foundation. This will result in the formation between the old and new concrete joints together seepage, leakage gap. 3, since the stress cracks in the concrete water leakage of concrete since the stress cracks in the concrete wall is often easy to produce, it is usually in the form of up and down through the cracks in the concrete walls of the entire exhibit regularity cracks, general In a 3 ~ 5m. This kind of self-stress concrete cracks are caused due to the heat of hydration of cement concrete reaches a certain extent, the expansion stress of concrete began to disappear at a time when the concrete began to produce contraction. This shrinkage is uniform shrinkage, so in such conditions, cracks concrete wall exhibits regularity of cracks. 4. Deformation of concrete water leakage in the construction process water stop not securely installed, resulting in a shift when tamping water stop. Another is near the concrete drain water stop ramming or tamping not dense, causing leaks exist on both sides of the concrete Deformation holes. Fourth, plugging measures based on the situation analysis of the causes of water leakage, the above four cases are now single SL-999 high pressure liquid plugging perfusion machine Sl-668 single-component PU foam injection sealing structure, the its reinforcing structure, in order to achieve the stanch effect. Fifth, the main construction material and highly performance 1, Sl-668 single-component PU foam sealing agent performance parameter index 3, sealing the needle perfusion single-needle machine with high pressure, fixed on drilling at ease into the foam Six sealing agent materials, construction methods (a), grain filling stage of the process (b), the specific construction method 2, since the structure of stress cracks leak water (1), inclined to the left or right crack lowest at 5 cm - 10 cm Drilling to half the thickness of the deep structure, progressive uphill from the lower 20 cm - 30 cm distance between holes is appropriate, to the highest point and then drilled a needle buried seal, due to the general structure of the case does not crack Rules like, so pay special attention to the time required to cross the fracture surface drilling, injection will be effective. (2), after the completion of the high-pressure perfusion, you can remove the sealing needle, and then fill the hole with sealing compound. 2, the construction joint leakage (1), due to the construction joints at the lowest left or right tilt at 5 cm ~ 10 cm deep drilling to half the thickness of the structure, progressive uphill from the lower drilling distance of 20 cm - 30 cm appropriate, to the highest point of the drill is once again buried the needle seal, due to the general structure of the genus irregular cracks, so pay special attention when drilling, fracture surface shall be crossed, will have the effect of injection. (2), after the infusion is complete, you can remove the sealing needle, and then fill the hole with sealing compound. Culvert plugging waterproof construction
