Description
Technical Field
The utility model belongs to the technical field of hydraulic structure, a under water wall reaming or trompil technique is related to, specifically is a novel reinforced structure is reformed transform in under water wall reaming or trompil.
Background
The underwater wall reaming or hole-opening reconstruction and reinforcement is common in the reconstruction of wading buildings such as pumping stations, power station plants and the like in China, and the important difficulty in reconstruction is how to prevent seepage because the underwater wall reaming or hole-opening reconstruction and reinforcement is positioned underwater. At present, the outer surface of an underwater wall of most factory buildings is directly connected with a forebay, and the operation condition is long-term underwater operation; the inner surface is a wall surface of a plant operation layer and is under a water-free working condition. The common seepage-proofing mode is to fill expanded concrete between the sleeve and the hole wall, the reinforcing mode is influenced by construction quality and material quality, water seepage channels are easily formed at joints of the expanded concrete, a raw water lower wall body and the sleeve, water seepage and other problems often occur, and the effect is not ideal.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem that the infiltration appears in under water wall reaming or trompil transformation, the utility model discloses a novel reinforced structure is reformed transform in under water wall reaming or trompil reaches the technical effect of comprehensive shutoff under water wall through the structure that changes reaming or the whole seepage prevention shutoff of trompil back-pored pipe.
The utility model discloses a technical scheme be, a novel reinforced structure is reformed transform to wall reaming or trompil under water, including the sleeve pipe of suit in the pipeline periphery and the wall body under water, the sleeve pipe with be provided with the concrete filling layer between the wall body under water, the nearly water top layer of wall body under water be provided with the concrete coating, concrete filling layer and concrete coating intercommunication, form the structure that shape of cross section is "L" type.
The concrete coating and the underwater wall body are fixed by means of expansion bolts.
The thickness of the concrete coating is 150-250 mm.
And a hemp cut asphalt interlayer is arranged between the pipeline and the sleeve.
And the areas enclosed by the two end surfaces of the hemp cut asphalt interlayer, the inner surface of the sleeve and the outer surface of the pipeline are subjected to pointing by asbestos cement.
The utility model has the advantages that:
the concrete coating is arranged on the near-water surface layer of the underwater wall body and is integrated with the concrete filling layer around the sleeve, so that the possibility that a water seepage channel is formed at the joint of the original underwater wall body and the new concrete filling layer is eliminated. Meanwhile, the whole formed by the concrete coating and the concrete filling layer is fixed with the original underwater wall body through the expansion bolts, so that the expansion concrete filling is more stable and firm than the expansion concrete filling only around the sleeve, and the expansion concrete filling device is simple, easy to operate, reliable and economical.
The possibility of forming a water seepage channel between the pipeline and the sleeve can be eliminated by filling the hemp-cut asphalt interlayer, and the inner surface and the outer surface are subjected to asbestos cement pointing and plastering, so that the strength and the corrosion resistance can be effectively improved, the durability and the reliability are improved, and the possibility of water seepage between the pipeline and the sleeve is greatly reduced.
The present invention will be described in detail with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the attached drawing, 1 is an underwater wall, 2 is a concrete coating, 3 is a reinforcing steel bar, 4 is an expansion bolt, 5 is a sleeve, 6 is a pipeline, 7 is asbestos cement, 8 is a hemp cut asphalt interlayer, and 9 is a concrete filling layer.
Detailed Description
As shown in figure 1, the novel underwater wall reaming or hole-opening transformation reinforcing structure comprises a sleeve 5 sleeved on the periphery of a pipeline 6 and an underwater wall 1, theoretically, the penetration amount is in direct proportion to a water head and in inverse proportion to the penetration path length, a concrete coating 2 is additionally arranged on a near-water surface layer and forms a whole with a concrete filling layer 9 around the sleeve 5, and the penetration length is greatly increased compared with the case that the concrete filling is only carried out around the sleeve 5. Therefore, a concrete filling layer 9 is arranged between the sleeve 5 and the underwater wall 1, and a concrete coating layer 2 is arranged on the surface layer of the underwater wall 1 close to water. The concrete filling layer 9 is communicated with the concrete coating layer 2 to form a structure with an L-shaped cross section, so that the water seepage amount around the pipe is greatly reduced, and the problem of water seepage after the underwater wall is reinforced is effectively solved.
For a more secure connection, the concrete cladding 2 is fixed to the underwater wall 1 by means of expansion bolts 4. And a hemp cut asphalt interlayer 8 is arranged between the pipeline 6 and the sleeve 5. And the areas enclosed by the two end surfaces of the hemp cut asphalt interlayer 8, the inner surface of the sleeve 5 and the outer surface of the pipeline 6 are caulked by asbestos cement 7.
The possibility of forming a water seepage channel between the pipeline 6 and the sleeve 5 can be eliminated by the gunny-knife asphalt filling, and the inner surface and the outer surface are subjected to asbestos cement 7 pointing and plastering, so that the strength and the corrosion resistance can be effectively improved, the durability and the reliability are improved, and the possibility of water seepage between the pipeline 6 and the sleeve 5 is greatly reduced.
