The first method comprises the following steps: the concrete structure is internally provided with embedded parts, and the steel structure is welded and then subjected to anti-corrosion coating so as to achieve the anti-seepage effect. The design has the following technical defects: the workload of the operation is large, and the consumption of materials and resources is high; the operation period is long, and the technical requirements on operators are high; the work type requirement on operators is high; poor continuity between processes; is not beneficial to disassembly, assembly and maintenance, and has difficult quality guarantee. The method specifically comprises the following steps:
1) through the implementation of the scheme of welding and anti-corrosion measures, the structural strength is outstanding, but because the welding operation is easily influenced by factors such as the level of welding personnel, technical parameters of welding machines and tools, material performance, a welding method, a welding environment and the like, the defects of bubbles, slag inclusion and the like are inevitably generated, the occurrence of leakage is difficult to avoid, even if the leakage is found, the purpose is achieved through repeated work such as welding seam repair and the like, the workload is high, and the service quality guarantee period is short.
2) The manufacture and installation of the embedded part consume a large amount of steel and manpower.
3) Is not beneficial to the operation in the narrow space of the working face. At narrow and small positions of an operation surface, concrete pouring is prone to be not in place in concrete structure construction, vibration quality is difficult to guarantee, quality problems such as hollowing and the like are prone to occur when embedded parts are used, and meanwhile leakage can occur due to the defects of the hollowing.
4) Is not beneficial to field operation, especially the construction in the area with short power resource supply.
5) The anticorrosion painting operation of the technical scheme is in an open air environment, and is not beneficial to environmental protection.
6) Through welding operation, form rigid connection between messenger's steel construction and the concrete foundation, be unfavorable for secondary dismouting to overhaul the inspection, especially to the condition that there is stress in the horizontal direction, be difficult to overcome.
And the second method comprises the following steps: the concrete structure is internally provided with the embedded bolts, the rubber pad is arranged in the middle of the concrete structure, and the concrete structure is fastened with the steel structure through the bolts, so that the anti-seepage effect is achieved. The design has the following technical defects: the construction precision requirement is high, the consumed resources are more, the workload is large, and the cost is high. The method specifically comprises the following steps:
1) in the process of embedding the bolts, the requirement on the technical size is high, and the workload is large.
2) The steel structure body needs to be holed, and the interval size and the machining precision have high requirements.
3) In concrete construction, insurmountable accumulated error defects inevitably exist among the concrete surface flatness, the rubber pad flatness and the steel structure surface flatness, bolt fastening torque is different, the joint surface is difficult to guarantee to be seamless through bolt fastening, and the leakage probability is very high.
4) During installation, the punching operation time is long and the number of workers is large due to the fact that holes are formed in the punching operation time and lines are long.
Therefore, a new anti-seepage technology needs to be designed at present, so that on the premise of reaching the anti-seepage technical standard, green construction, environment protection, labor intensity reduction, engineering cost reduction, labor productivity improvement multiplied by times and social science and technology productivity improvement are promoted.

Detailed Description
In order to more clearly illustrate the invention, the invention is further described below in connection with preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
The invention takes two typical rigid materials of concrete and steel structure as examples to describe the design scheme and the installation method of the invention.
The first step is as follows: as shown in fig. 1 and 2, a concrete structure 2 is prepared, and a groove 1 is prepared on the upper surface of the concrete structure before the concrete structure is initially set, and the center line of the groove is positioned on the basis of a protective layer which does not affect the concrete structure 2.
The technical requirements of the groove are as follows: the appearance is neat and beautiful, the upper opening is not obviously protruded, and the section area of the groove is smaller than that of the sealing water stop strip. Namely, on the section perpendicular to the joint end surface of the first rigid structure and the second rigid structure, the size of the groove is smaller than that of the water stop sealing strip.
The second step is that: after the groove 1 is finished, the whole concrete structure 2 is covered and maintained by using a proper material, the concrete structure 2 can be disassembled after reaching the design strength, and the semi-finished product protection work for the groove 1 is well done in the whole process.
The third step: and (5) checking the flatness of the combined end face of the steel structure 4 to be in contact installation with the concrete structure 2, wherein the error is controlled within the range of the design requirement of the steel structure drawing.
The fourth step: as shown in fig. 3 and 4, the joint end face of the concrete structure 2, the groove 1 and the joint end face of the steel structure 4 are purged and cleaned, and then the water-stop sealing strip 3 is laid on the groove 1.
The fifth step: as shown in fig. 5, the hoisting of the steel structure is completed, the water-stop sealing strip 3 at the joint is detected, the deformation occurs, and all the work is completed.
After the installation, the water-stop sealing strip is tightly clamped in the concrete structure under the pressure of the steel structure, and the end surface of one side far away from the groove tightly contacts the combined end surface of the steel structure, so that the water-stop sealing strip deforms. If the section of the water-stop sealing strip is not deformed, the situation that the section is not tightly combined is indicated, the groove and the combined end face of the steel structure need to be checked and adjusted, and finally the water-stop sealing strip is tightly contacted with the concrete structure and the steel structure so as to achieve the effect of preventing water seepage.
Compared with the traditional mode, the work efficiency of the anti-seepage device is improved by 7 to 8 times, the economic cost of each anti-seepage length is reduced by at least 2000 yuan, and the anti-seepage device is very suitable for being applied in the field environment.
It will be readily understood by those skilled in the art that the concrete and steel structures may be other rigid structures. The combination mode can be other modes, the upper and lower combination mode is adopted in the preferred embodiment, and the sealing effect can be achieved only by utilizing the gravity of a steel structure; if the water-stop sealing strip is combined left and right or combined in other directions, an additional clamping device is needed to tightly press the combined end faces, so that the water-stop sealing strip is tightly pressed between the combined end faces to achieve the effect of preventing water seepage.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the invention and are not to be construed as limiting the embodiments of the present invention, and it will be apparent to those skilled in the art that other variations and modifications can be made on the basis of the above description.
