Abstract
The invention discloses a construction method for restoration of secondary hole excavation in a constructed roof for pipeline penetration. The constructed roof comprises a waterproof roll layer, an insulation board layer and a concrete layer which are arranged on a structural roof board from bottom to top. The construction method includes: excavating a penetrating pipeline hole in the constructed roof and inserting a pipeline into the pipeline hole; chiseling the constructed roof circumferentially by centering on the pipeline and chiseling till the waterproof roll layer is reached so as to form a chiseling area; brushing waterproof paint on the surface, exposed over the chiseling area, of the pipeline and the surface of the waterproof roll layer in the chiseling area; pouring concrete in the chiseling area and vibrating to allow the concrete to be compact. The construction method has the advantage that reaction sticky waterproof rolls are paved on the pipeline in the secondary hole and the waterproof roll layer in the chiseling area, and the concrete is poured in the chiseling area and vibrated to be compact, so that good waterproof effect can be achieved.
Description
Technical field
The present invention relates to building engineering field, the construction method that the poling that punches after referring in particular to a kind of roofing of having constructed is repaired.
Background technology
Construction works more of the prior art, due to the reason such as change of design scheme, cause having pipeline through the roofing of having constructed, must again must to punch after roofing, and to punch the process of repairing to its secondary.Because roof waterproof now, insulation and rigid layer have all been constructed, on shaping roofing floor, secondary punches and wears fire main, possesses great leakage hidden trouble.Further, roofing poling does not belong to identical material due to tube wall and concrete, and compatible poor, there is thermal stresses, and be very easy to cracking near the mouth of pipe, be roof waterproof technological difficulties always.
In order to improve the water resistance of roofing, in prior art, normal waterproof roll or the water-repellent paint of adopting carries out waterproofing work to Roof system.When adopting waterproof roll as roof waterproof construction, waterproof roll cannot receive head at this position coiled material, can only receive head by water-repellent paint or construction sealant, is the position easily occurring cracking under thermal stresses and aging action impact.When adopting water-repellent paint as roof waterproof construction; water-repellent paint construction is complete all to be protected by cement mortar, and general thickness of mortar coverage, at 20mm ~ 30mm, closes up at drain gully position mortar and more easily occurs problem of Cracking; even destroy original waterproofing course, cause seepage.
Therefore, in prior art, to and the roofing secondary that completes construction punch carry out poling the mouth of pipe near cracking, seepage and the repair process technical problem that become this area urgently to be resolved hurrily.
