Through pouring the two-shot grouting material of slight expansion between the opening that has V type annular in the inboard and the steel waterproof casing pipe that has the seal ring, make its three fully combine, can play better prevention of seepage, leak protection effect, can effectual extension this structure's life moreover.
Compared with the traditional construction method, the utility model, it is little to have the opening, consolidates the convenience, and the engineering volume is little, reduces the engineering volume more than 80%, makes its leak protection, seepage prevention rate improve 90%, reaches leak protection, prevention of seepage, increase of service life's purpose.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a micro-expansion secondary grouting material layer, 2. V-shaped ring grooves, 3. L-shaped reinforcing steel bars, 4. a hole, 5. water pool wall inner reinforcing steel bars, 6. a steel waterproof sleeve and 7. a water stop ring.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
referring to fig. 1, a construction method for reinforcing and preventing leakage by forming a hole in the side wall of an old pool comprises the following steps:
1) firstly, chiseling a hole on the side wall of the pool, wherein the radius of the hole is 65-75 mm larger than that of the steel waterproof sleeve 6;
2) chiseling concrete on the tank walls at two ends of the hole to enable the two ends of the hole to be annular and to leak out of the reinforcing steel bars 5 in the tank wall, wherein the leaking length of the reinforcing steel bars 5 in the tank wall is 180mm-200mm, and chiseling a plurality of V-shaped annular grooves 2 on the inner wall of the hole;
3) then inserting the steel waterproof sleeve 6 with the water stop ring 7 into the hole 4, and welding and fixing the L-shaped steel bar 3 with the steel bar 5 in the pool wall and the steel waterproof sleeve 6 respectively;
4) and (3) grouting the gap between the steel waterproof sleeve 6 and the inner wall of the hole at two ends of the hole by adopting pressure, and pouring the micro-expansion secondary grouting material.
The micro-expansion secondary grouting material is pressed and then embedded into the V-shaped ring groove 2 on the inner wall of the hole, so that a plurality of V-shaped anchoring structures surrounding along the circumferential direction are formed between the solidified micro-expansion secondary grouting material layer 1 and the original concrete of the hole, and the chiseled part around the hole is firmly blocked to form a tight water sealing structure.
The utility model provides a hole is opened to old pond lateral wall and is consolidated leak-proof construction structures, includes L shaped steel bar 3, steel waterproof sleeve 6, the secondary grout bed of material that slightly expands 1, steel waterproof sleeve 6 and L shaped steel bar 3 welded fastening, L shaped steel bar 3 and the pool wall in reinforcing bar 5 welded fastening it has the secondary grout bed of material that slightly expands 1 to fill between steel waterproof sleeve 6 and the pool wall entrance to a cave concrete, be equipped with V type annular 2 on the pool wall entrance to a cave concrete inner wall, slightly expand secondary grout bed of material 1 embedding V type annular 2.
And water stop rings 7 are arranged on two sides of the steel waterproof casing 6. The thickness of the steel waterproof sleeve 6 is not less than 1.5 times of the diameter of the steel bar. The steel waterproof sleeve 6 is welded and fixed with the reinforcing steel bars 5 in the pool wall through the L-shaped reinforcing steel bars 3, and the functions of reinforcing the pool wall and fixing the sleeve are achieved. And water stop rings 7 at two ends of the steel waterproof sleeve 6 are buckled outside the micro-expansion secondary grouting material layer 1 and are tightly combined and fixed with the condensed micro-expansion secondary grouting material layer 1 to form a water sealing layer and protect right angles of the end wall of the hole.
Example 1:
in order to reduce the engineering investment, an old water tank is required to be transformed by a deep treatment project for recycling waste water of a large-scale steel mill, holes need to be formed in the side wall of the old water tank, the wall thickness of the water tank is 500mm, and the diameter of a preset hole is 200mm (the inner diameter of a steel waterproof sleeve 6 is 200 mm). Firstly, a constructor opens a hole in the side wall of the old pool, and the radius of the opening of the hole is 70mm larger than that of the steel waterproof casing 6. And chiseling concrete on the tank walls at the two ends of the opening to enable the two ends of the opening to be annular, and leaking out the reinforcing steel bars 5 in the tank wall, wherein the leaking length of the reinforcing steel bars 5 in the tank wall is 180 mm. Then two V-shaped ring grooves 2 are chiseled on the inner wall of the opening. And then inserting the steel waterproof sleeve 6 with the water stop ring 7 into the hole, and respectively welding the L-shaped steel bars 3 with the water tank wall internal steel bars 5 and the steel waterproof sleeve 6 to integrally connect the steel waterproof sleeve 6 with the water tank wall internal steel bars 5. And finally, grouting the gap between the steel waterproof casing 6 and the hole opening by adopting pressure, and pouring the micro-expansion secondary grouting material. The utility model discloses the construction is simple, and the outward appearance forms a whole with the pond to ensure no seepage.
