Therefore, it is necessary to repair and protect the sea erosion column.
In recent years, the reinforcement technology of microorganism-induced calcium carbonate precipitation (MICP) has made up the limitation of traditional repair methods in engineering applications.

The microbial flora in the microbial slurry is extracted from the marine corrosion column, so that the microbial slurry is matched with the marine corrosion column to be repaired, the texture and color of the repaired marine corrosion column are basically the same as the original texture and color, and the original appearance of the marine corrosion column is maintained to the maximum extent. Reinforcing bar 3 uses with the cooperation of microorganism thick liquid, on the basis of mechanical hard joint, cooperates the microorganism to restore for the restoration mode of physics and chemistry combines together, further improves the performance of restoration material.
The microorganism mortar is also formed by using calcium carbonate crystals generated by microorganism induction and gelling by taking a granular substance as a framework. The microbial flora is extracted from the original marine corrosion column and applied to the repair and protection of the marine corrosion column, and has the advantages of strong bonding capability and strong controllability.
The microorganism slurry is the existing slurry, is basically a mixture of the microorganism liquid and the nutrient solution, sand and stone can be added into the slurry under the condition of requirement, the slurry added with the sand and stone has higher viscosity, and larger pores can be conveniently filled. Wherein, the amount of the added sand and stone can be set according to actual needs, and the sand and the microorganism slurry do not produce chemical reaction and belong to physical mixing.
Generally, the upper part of the sea erosion column collapses, the bottom part of the sea erosion column remains, the remaining part of the bottom part can be used as the base 1, a plurality of parts formed after the upper part collapses have different volumes, the part with the larger volume can be used as the main part 2, and the part with the smaller volume can be used as the secondary part.
In the screening and classification, the screening conditions not only include the volume of each part, but also comprehensively consider the hardness and the crack distribution of each part.
Since the sea-erosion columns are bulky and collapse is mostly due to breakage of the weak link, the sea-erosion columns collapse to form the base 1 and a main portion 2 in most cases. In the present embodiment, a description will be given taking one main portion 2 as an example.
In primary repair, comprising:
s11, a first mounting hole is formed in the base 1, and a second mounting hole is formed in the main part 2;
s12, after the reinforcing steel bar 3 penetrates through the first mounting hole, injecting microorganism slurry into the first mounting hole, so that the microorganism slurry permeates into the first mounting hole until the microorganism slurry is gelled and solidified, and fixing the reinforcing steel bar 3 and the base 1;
and S13, sleeving the main part 2 on the steel bar 3 through a second mounting hole.
In first mounting hole, the microorganism thick liquid surrounds reinforcing bar 3, forms the protection to reinforcing bar 3, prevents the first mounting hole of water infiltration, avoids 3 corrosion of reinforcing bar, increase of service life.
What above-mentioned adopt is that insert earlier reinforcing bar 3 and locate first mounting hole, insert the mode of second mounting hole with reinforcing bar 3 again, can also be, insert earlier reinforcing bar 3 and locate the second mounting hole, insert reinforcing bar 3 again in first mounting hole, for example: after the reinforcing steel bar 3 penetrates through the second mounting hole, injecting microbial slurry into the second mounting hole, so that the microbial slurry permeates into the second mounting hole until the microbial slurry is gelled and solidified, and fixing the reinforcing steel bar 3 and the main part 2; the reinforcing steel bar 3 is arranged in the first mounting hole in a penetrating mode, so that the main portion 2 is abutted to the base 1.
Between S12 and S13, further comprising:
s121, coating microorganism slurry on the fracture surface of the base 1 and/or coating microorganism slurry on the fracture surface of the main part 2;
in S13, when the main portion 2 is sleeved on the reinforcing steel bar 3, the fracture surface of the main portion 2 is attached to the fracture surface of the base 1, and after the microbial slurry is gelled and solidified, the main portion 2 is bonded to the base 1.
The fracture surfaces are bonded through microbial slurry, so that the contact area of the main part 2 and the base 1 is increased, and the repair is more stable.
In S11, when the first installation hole is formed in the base 1, the crack on the base 1 is avoided to ensure the structural strength, so that the reinforcing steel bar 3 may extend in the vertical direction or in an inclined direction, which is not limited herein. It will be appreciated that the number of rebars 3 may be chosen as a practical matter.
In order to prevent water from entering the second mounting hole, in this embodiment, the second mounting hole is a through hole, and after S13, the method further includes:

Although the second mounting hole is a through hole, the filling of the second mounting hole is completed after the microbial slurry is gelled and solidified due to the injection of the microbial slurry, and the structural strength is not affected.
The edge of the base 1 bordering the main portion 2 may be smoothed with a microbial slurry.
In first-level repairs, the fill includes a minor portion and a stone block. The secondary part is used as a filler, so that the rock of the sea corrosion column can be utilized more, and the texture and the original appearance are ensured; under the condition that the number of the concave positions and the cavities is large, block stone filling can be added to ensure the stability of repair. After the filler is filled to the position, the microbial grout is used for grouting, so that the filler is coagulated and gathered into a whole, and the structural strength is ensured.
The microorganism grouting technology is the prior art, namely microorganism slurry is poured into the position of a filler under the action of pressure, and the pressure can be provided by a pump. Grouting can be completed once or in multiple times to ensure that the microorganism slurry is fully permeated and solidified.
It will be appreciated that the recessed locations and cavities, which are unique to the marine pillar itself and which have some ornamental value, may not be filled.
In the second-stage repair, the position of the crack is grouted by microorganism slurry, so that the microorganism slurry permeates in the crack until the microorganism slurry is gelled and solidified. The filling of the crack can prevent water from permeating into the crack, and the structural strength and the service life of the sea corrosion column are improved.
The microbial grouting technology is the prior art and has the same principle as the microbial grouting, namely, under the action of pressure, microbial slurry is injected into a crack, and the pressure can be provided by a pump. The grouting can be completed once or in multiple times to ensure that the microorganism slurry is fully permeated and solidified.
In the final stage repair, the external surface of the sea erosion column is sprayed with microorganism slurry to form a microorganism film. The microbial film can prevent seawater from corroding the sea corrosion column, and the structural strength and the service life of the sea corrosion column are improved.
Before screening classification, the method comprises the following steps:
s01, acquiring three-dimensional data and fracture positions of a sea erosion column to be repaired, and establishing a three-dimensional model of the sea erosion column in a computer according to the three-dimensional data;
s02, simulating and repairing the three-dimensional model, and sketching the development trend of the fracture to obtain a fracture development position diagram.
By collecting data, the sea erosion column is more comprehensively known, and a targeted scheme is convenient to formulate.
In the second-level repair, the cracks on the sea erosion column are grouted according to the crack development position diagram. The crack filling machine has higher pertinence, so that the crack filling is quicker and the effect is better.
In S01, three-dimensional data and fracture positions of the marine corrosion column to be repaired are obtained through geological radar survey and sound wave detection. The three-dimensional data comprise the shape and the size of the sea corrosion column, and the setting position of the steel bar 3 can be determined according to the obtained three-dimensional data, so that the steel bar 3 can better support the sea corrosion column.
