Description

Gas shield dam installation anchoring system and method

Technical Field

The invention relates to an air shield dam installation anchoring system and method, and belongs to the technical field of water blocking and water conservancy facility construction.

Background

The dam is an important facility of modern water conservancy and plays an important role and income in various fields of the national civilization. From earth dams, concrete dams, steel dams (gates), rubber dams to today's air shield dams. The air shield dam inherits the essence of the traditional movable dam type, overcomes the bottleneck problem of the traditional movable dam type, and has the characteristics of simple structure and simple and rapid construction, installation, use and maintenance; the flood control and flood-fighting capacity is outstanding, and the operation is safe and reliable; the water passing height and the running state are continuously controllable; has stronger capabilities of cleaning sewage and discharging silt; the water retaining and passing capacity is higher; the charging and discharging time is short, and the operation management is simple; the service life is ultra-long, and the comprehensive benefit is high; the shock resistance is strong, and the adaptability to the foundation is high; the landscape effect is good, and the landscape device has the characteristics of ecology, environmental friendliness and the like.

The main anchor system of the air shield dam is characterized in that a rubber air bag and a steel shield plate are fixed on a river bed through a pressing plate by using a main anchor component to form a sealed capsule body, and the main anchor system is a key factor for judging whether the air shield dam can play a role in stably retaining water.

The structural form of the main anchor system is generally divided into two types: when the water retaining height is lower (such as below 2.5 meters), an air bag perforation mode is adopted; when the water retaining height is higher, an air bag non-perforation form is adopted.

In engineering construction, the pre-burying and anchoring of main anchor bolts are a very important link of the whole engineering, the success or failure of the installation of the air shield dam is directly influenced by the quality of an anchoring system and construction quality control, and the selection of the anchoring system and the construction method has great influence on the engineering quality and the construction period.

When the main anchor of the general engineering is a pre-embedded bolt, the bolt pressing plate is adopted to fix the position of the anchor bolt, and the theodolite is used for observation to ensure that the central line of the anchor bolt is on the same straight line. Measuring the height of the anchor bolt by using a leveling instrument, comparing with the design requirement to confirm no error, fixing a bolt pressure plate in the anchor groove by using a wood support, welding the embedded parts together by using a through long steel bar according to the design interval, and pouring anchor groove concrete after determining that the anchor bolt is not suitable to move after being stressed, wherein the pouring of the concrete is carried out in two stages in order to ensure the construction quality of the anchor bolt; when concrete is poured to a position 100mm away from the bottom of the anchoring groove in the first period, the central position, the elevation, the absolute position, the distance and the stability of the anchoring bolt are observed again, the anchoring bolt is reset in time after deviation is found, in the pouring process, a theodolite is erected at an anchoring line control point for on-site monitoring, displacement is found, and correction is carried out immediately; a phi 18 steel bar is welded on the lower part of the pressure plate to be used as a pressing rib, so that the anchoring pressure is increased; and after the second-stage concrete pouring, observing and correcting the concrete again before the initial setting of the concrete. When the dam baseboard concrete meets the standard requirement, the bolt pressing plate anchoring installation can be carried out according to the following steps; the pressing plates are aligned end to end, and are flatly padded by rubber sheets when the pressing plates are not flat; screwing the screw cap for multiple times when the screw cap is screwed, and screwing the screw cap again after the dam bag water filling test; when the nut is screwed, the bolts are screwed down one by one according to the set torque by using a torque wrench; the butt joint of the rolled pressing shaft (wood core or steel pipe) is staggered with the joint of the pressing plate, so that the phenomenon of local water leakage caused by soft joint is avoided.

1) during on-site construction, the accuracy of embedding the bolt is difficult to realize;

2) after the air shield dam is installed, air leakage or slow air leakage of the air bag often occurs;

3) concrete needs to be poured in two stages, construction is extremely complicated and complex, construction period is long, requirements on skill level and construction experience of constructors are high, and labor intensity is high;

4) the upper pressing plate of the air shield dam with a higher water head in a non-perforation anchoring mode is complex in shape, the main anchoring bolts and the main anchoring positioning construction and the installation of the air shield dam are more rigorous and complex, the requirement is high, the influence of human factors is great, and the labor intensity is high.
