Abstract
The invention discloses a method and a structure for adding a partition in a prior pool. A structural slot is arranged at the joint between the prior pool and the added partition, and the slot wall of the structural slot is roughened; the width of the structural slot is larger than the thickness of the added partition, which is added with an extended section multiplied by 2, so that reinforcing steel bars in the prior pool are exposed; new reinforcing steel bars are woven as strengthening reinforcing steel bars for the added partition and strengthening slabs at the joint between the added partition and the prior pool; and a mold then casts concrete to mold the added partition and the strengthening slabs in one step. The method is simple and practical, and the structure can be safely and reliably used. The strength of the joint between the partition and the prior pool can be enhanced, and leakage at the joint between the new concrete and the oil concrete can be prevented.
Description
Technical field
The present invention relates to a kind of concrete basin improvement project, particularly a kind of in prior pool the method and the structure of adding partition.
Background technology
In the process of modernizing and expanding the existing factory, need two ponds to store different liquid, but can not build in addition by place or other condition restriction, and transform in original pond, increasing dividing plate.The pond of transforming is a reinforced concrete structure, owing to work under certain water pressure, there is strict antiseep requirement in the pond.According to purpose engineering practice in the past, once adopted the reinforcement cover of rejecting at the bottom of original pool wall and the pond with the adding partition junction, will newly add on the reinforcing bar that reinforcing bar directly is welded in former pond, again the method for fluid concrete.But said method can not improve the bearing capacity of dividing plate to hydraulic pressure, after use a period of time, produces microcrack in the new-old concrete junction, makes liquid produce seepage, and effect is undesirable.In case very fast meeting makes the crack more and more wideer under hydraulic action after the generation seepage, it is serious to leak, and finally damages, and can't use.
Summary of the invention
The objective of the invention is: a kind of simple and practical and safe in utilization, the reliably method and the structure of adding partition in prior pool are provided, to increase the intensity of dividing plate and junction, former pond, prevent to produce seepage, thereby overcome the deficiencies in the prior art in the junction of new-old concrete.
Technical scheme of the present invention: of the present invention a kind of in prior pool the method for adding partition be to have the structure groove in the junction of former pond and adding partition, the cell wall hacking of structure groove; Structure groove width＞adding partition thickness+2 * extension makes the reinforcing bar in the former pond expose out; Reinforced steel with new reinforcing bar establishment adding partition and adding partition and former pond binding site stiffener; Molding is with an adding partition and a stiffener cast molding of concrete then.
Above-mentioned in prior pool in the method for adding partition, the thickness of described adding partition is not less than former pond wall thickness.
Aforesaid in prior pool in the method for adding partition, described stiffener comprises the end stiffener of adding partition and former tank floor junction and the side stiffener of adding partition and sidewall junction, former pond; The thickness of end stiffener and side stiffener is not less than former pond wall thickness.
Aforesaid in prior pool in the method for adding partition, described reinforced steel adopts the HRB335 grade reinforcing steel, and bar diameter is not less than 12mm, and spacing is not more than 200mm.
Aforesaid in prior pool in the method for adding partition, described concrete grade is than the high one-level of the used concrete strength in former pond, and is not less than C25, and impervious absolute altitude is not less than S8.
Aforesaid in prior pool in the method for adding partition, described extension is the length that end stiffener or side stiffener exceed the adding partition both sides, and extension length is not less than 500mm.
According to method of the present invention implement of the present invention a kind of in prior pool the structure of adding partition be: it comprises former pond; Be provided with adding partition in former pond, the adding partition two ends are provided with the side stiffener; The adding partition base plate is provided with end stiffener; The side stiffener is connected with base plate with the sidewall in former pond respectively with end stiffener.
Above-mentioned in the structure of adding partition, have engagement groove on the former pond of described side stiffener and end stiffener and junction, former pond in prior pool, the width of engagement groove is greater than the width of side stiffener or end stiffener.
Aforesaidly in prior pool, in the structure of adding partition, be provided with reinforced steel in described adding partition, side stiffener and the end stiffener, the former pond reinforcing bar welding on reinforced steel and the former pond.
Owing to adopted technique scheme, the present invention is provided with stiffener in the junction in adding partition and former pond, and the junction in stiffener and former pond has engagement groove, the cell wall hacking of structure groove; To strengthen the combination of new-old concrete.The reinforced steel in the stiffener and the former pond reinforcing bar in pond, engagement groove Central Plains weld together, and have increased bonding strength.Because stiffener is trapped in the engagement groove, and structure groove width＞adding partition thickness+2 * extension, the permeation pathway that has prolonged water greatly effectively stops the phenomenon that occurs seepage at binding site.So the present invention compared with prior art, the present invention can effectively increase the intensity of dividing plate and junction, former pond, prevents to produce seepage in the junction of new-old concrete; In addition, method of the present invention is simple and practical, and safe in utilization, reliable.
