Description
Technical Field
The utility model belongs to the technical field of the design and the manufacturing of building engineering equipment, concretely relates to bury formula rubber waterstop steel sheet connecting piece in utility tunnel is used.
Background
The construction of the urban underground comprehensive pipe gallery is an important measure for innovating urban infrastructure, so that the repeated excavation of roads caused by pipeline burying or maintenance can be avoided, the direct corrosion of soil to pipelines is avoided, the service life of the pipelines is greatly prolonged, and the urban comprehensive bearing capacity is improved. However, the problem of water leakage is always a common quality problem which puzzles underground construction projects, the phenomenon that pipelines are soaked by water leakage for a long time is avoided, and the problem of good water resistance is one of the technical problems which must be considered in the construction of the comprehensive pipe gallery. The difficulty of waterproofing the utility tunnel is that the detailed structure is waterproof, and if the treatment is not good, the leakage phenomenon is very common. And therefore must be given sufficient attention. The waterproof treatment at the expansion joint determines the success or failure of the waterproof effect of the detailed structure of the expansion joint, and the connection of the rubber water stop belt is more important in the waterproof effect at the expansion joint. In the actual work progress, traditional adhesive cold joint method can't satisfy utility tunnel waterproof requirement, and the waterproof requirement can be satisfied to on-the-spot hot vulcanization method, nevertheless is all inconvenient for providing operation platform because of joint department, and the construction degree of difficulty is great.
Disclosure of Invention
An object of the utility model is to provide a bury formula rubber waterstop steel sheet connecting piece in, thereby this connecting piece can effectively solve expansion joint department waterproof problem and guarantee utility tunnel's construction quality, and then alleviates intensity of labour, also can fundamentally reduce hidden danger, reduces later stage operation maintenance cost, increase of service life.
The technical scheme of the utility model: the utility model provides a bury formula rubber waterstop steel sheet connecting piece in utility tunnel is used, includes upper and lower two-layer steel sheet, steel sheet thickness is less than or equal to 10mm and the bolt and the nut of fixed steel sheet upper and lower two-layer steel sheet between be equipped with bury formula rubber waterstop in the middle of be equipped with the waterproof layer, be equipped with the asphalt mastic layer between steel sheet and rubber waterstop.
Has the advantages that: the connecting piece is simple in principle and easy to implement and operate, operation and control are facilitated in the construction process of operating personnel, the construction period is shortened, the construction efficiency is improved, and the construction cost is reasonably saved.
Drawings
Fig. 1 is a schematic plan view of the present invention; FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1; fig. 3 is a sectional view taken along line B-B of fig. 1.
Detailed Description
The utility model provides a bury formula rubber waterstop steel sheet connecting piece in underground utility tunnel is used, as shown in attached figure 1 and attached figure 2 and attached figure 3, includes upper and lower two-layer steel sheet 1, and steel sheet 1 thickness is less than or equal to 10mm to and the bolt 2 and the nut 5 of fixed steel sheet upper and lower two-layer steel sheet 1 between be equipped with bury formula rubber waterstop 3 in the middle of 3, rubber waterstop be equipped with waterproof layer 4 between steel sheet 1 and rubber waterstop 3 and be equipped with pitch daub layer 6.
In the connecting piece, the steel plate can protect the rubber water stop joint from being broken due to factors such as settlement and deformation, the deformation caused by settlement is considered, the thickness of the steel plate is not more than 10mm, and the galvanized steel plate clamp is ensured to have certain deformation resistance elasticity. The self-adhesive water-proof coiled material (i.e. water-proof layer 4) with cross-laminated film is made up by using synthetic rubber, high-quality heavy-traffic asphalt, plasticizing agent, viscosity-increasing agent and anti-ageing agent as base material, using strong cross-laminated film as surface material and using anti-sticking isolating paper as isolating layer. The expansion joint has excellent elongation at break, and can adapt to settlement deformation at the expansion joint; the adhesive force is strong, the coiled material and the base layer have good adhesive property, the coiled material and the rubber waterstop are integrated after being bonded, the self-healing function is unique, and small holes can heal automatically.
