It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, a method for reinforcing the concrete integral structure with high density according to the present invention will now be described. The high-density reinforcing method for the concrete integral structure comprises the following steps:

fixing a plurality of reinforcing sheets along the specific direction of the structure to be reinforced, laying the protective film on the structure to be reinforced, and sealing edges of the protective film to ensure that a closed pouring cavity is defined between the protective film and the structure to be reinforced.

Through materials such as a plurality of location nails and adhesive linkage in this application, repaired and treated the reinforced structure, improved and treated the reinforced structure and resisted the ability of assaulting and warping, easy and simple to handle and respond well.

When a traditional structure to be reinforced is reinforced, firstly, the surface of the structure to be reinforced needs to be treated, the treatment comprises grooving and ash removal, and the surface of the structure to be reinforced needs to be kept wet before reinforcing materials are injected, so that the purpose of ensuring that the structure to be reinforced and the reinforcing materials have enough connecting force is achieved. However, even if the surface of the structure to be reinforced is covered with the same material as the structure to be reinforced, the situation that the connecting force is not strong still exists at the connecting position due to the difference of curing time, and even if the surface of the structure to be reinforced is processed, the structural strength of the surface is reduced due to the fact that the surface is corroded by the external environment for a long time, and dust which is not cleaned in time exists in the structure to be reinforced, so that the adhesion of the subsequent reinforcing material is influenced.

Can impress the bonding material in treating gap and the tiny pit in the reinforced structure through a plurality of fastening areas in this application, compare in the way among the prior art, the adhesive linkage of formation and treat that the joining force between the reinforced structure is great, consequently be difficult for leading to the adhesive linkage and treating the pine of reinforced structure and taking off.

and fixing the reinforcing pieces transversely and longitudinally along the structure to be reinforced by the reinforcing pieces, and adjusting the positions of the reinforcing pieces to enable the outer end parts of the reinforcing pieces positioned on the same side of the structure to be reinforced to be positioned in the same plane.

The reinforcing pieces need to be fixed according to a certain arrangement sequence, the reinforcing pieces are finally fixed in the adhesive layer, the protective film needs to be laid on the outer side of the reinforcing pieces after the reinforcing pieces are fixed, the outer end portions of the reinforcing pieces can be directly abutted to the protective film, and therefore the regularity of the shape of the final adhesive layer is guaranteed through the reinforcing pieces.

When the structure to be reinforced is a prism, the outer ends of the reinforcing pieces positioned on the same side of the prism are positioned in the same plane.

In some embodiments of the high-density reinforcing method for the concrete overall structure provided by the application, covering the protective film on the structure to be reinforced, and performing edge sealing treatment on the protective film to enable a closed pouring cavity to be defined between the protective film and the structure to be reinforced comprises:

and covering the protective film on the outer side of the structure to be reinforced to enable the protective film to form a protective sleeve wrapping the structure to be reinforced.

And fixing a sealing strip at the open end of the protective sleeve to form a pouring cavity at the inner side of the protective sleeve.

Because need ligature fastening band on the protective film, a plurality of fastening bands just can impress the binder in the defect of treating the reinforced structure through tightening up the pouring chamber, consequently need protective film itself to have certain thickness. The protective film is typically a rectangular roll, provided with two side edges, a top edge and a first bottom edge. In order to form a closed casting cavity, it is therefore necessary to butt the two sides, in which case the protective film is a protective sleeve with an upper opening and a lower opening. When the structure to be reinforced is an approximate cylindrical surface, the top end and the bottom end of the protective sleeve are respectively sleeved with the sealing strips, and the protective sleeve is pressed on the structure to be reinforced through the sealing strips. The both ends of sealing strip are connected with the retaining member, thereby tighten up the shutoff lag through rotating the retaining member messenger sealing strip.

When treating that reinforced structure is prismatic, the sealing strip need be with the help of bolt, screw or penetrating nail etc. this moment, thereby realize the shutoff to the lag through fixing the sealing strip on treating reinforced structure. It should be noted that, the leakproofness of pouring cavity is the key of guaranteeing that the binder can get into gap and pit, therefore usually can carry out the pressure testing in advance to pouring cavity when the practical application, just pour the binder on guaranteeing sealed basis.

After the sealing performance of the pouring cavity is ensured, a bonding material is required to be injected into the pouring cavity, and the bonding material can be liquid mixed by epoxy resin, a curing agent and a diluent according to a certain proportion. In the process of pouring the bonding material and after the plurality of fastening belts are bound, the protective film is required to be heated all the time, so that the flowability of the bonding material is ensured.

In order to fill the entire casting cavity with adhesive, it is therefore necessary to perform the injection from a casting opening at the bottom of the protective film, the exhaust opening being open during the injection. It should be noted that, a plurality of holes are formed on the reinforcing sheet, and the adhesive needs to completely enter the holes during actual casting, so that it can be ensured that the reinforcing sheet and the adhesive layer have sufficient connecting force after the adhesive is cured.

When the area of the structure to be reinforced is large, in order to reduce resistance when the bonding material is injected, the exhaust port can be communicated with the vacuum pump, and the mobility of the bonding material is improved through the vacuum pump.

However, a bulge of the protective film is formed between two adjacent fastening strips, which can affect the subsequent spraying of the protective material, resulting in a lower thickness of the protective material at the bulge. In order to avoid the above problem, when the structure to be reinforced is a cylindrical surface, the extrusion plate may be an arc plate, and the arc plate may be formed by splicing two semicircular arc plates. When the structure to be reinforced is prismatic, the extrusion plate may be made of a rectangular plate, and a plurality of rectangular plates are spliced with each other.

By providing a pressing plate between the fastening strips and the protective film, the flatness of the finally formed adhesive layer is ensured by means of the inner side of the pressing plate.

In some embodiments of the method for high-density reinforcement of concrete monolithic structures provided in the present application, before spraying the protective material on the bonding layer, the method further comprises:

and hanging the reinforcing net on the plurality of positioning nails, and butting the side edges of the reinforcing net to enable the reinforcing net to form a reinforcing sleeve sleeved on the bonding layer.

The bottom of location nail is bored into and is treated the reinforced structure in, and the top of location nail is located the outside of adhesive linkage, need to the outside spraying protective material of adhesive linkage, and protective material is as outer material, and its self structural strength is the key of guaranteeing that reinforced structure is stable to treat innermost after the adhesive linkage. The protective layer can be formed after the protective material is solidified, and in order to improve the structural strength of the protective layer, a reinforcing net is fixed at the top ends of the positioning nails before the protective material is sprayed. The sprayed protective material will enter the reinforcing mesh and eventually form an integral structure with the reinforcing mesh.

Only drill into the pilot pin after the adhesive linkage solidification in this application, the adhesive linkage has with treat that reinforced structure is connected, because the existence of adhesive linkage has consequently improved and has treated the ability that reinforced structure resists the deformation to treat reinforced structure secondary crack scheduling problem when having avoided driling. And just drill hole after the adhesive linkage solidification, can avoid treating the destruction of reinforced structure because reasons such as vibration during drilling, guaranteed integrality.
