Die block cradle supporting method for concrete engineering limited by tide

Abstract

The invention discloses a method for supporting a bottom mold hanging basket of a concrete project restricted by tides, which comprises the following steps: 1) determining the load-bearing part, the suspension part and the bottom mold support of the hanging basket according to the load of the upper cast-in-place cap The thickness and width of the steel plate to be used; 2) According to the pile body to support the hanging basket, the steel hanging basket is prefabricated. ; 3) Place the hanging basket on the top of the pile, and use the anchor bar of the cast-in-situ pile to cut off the load-bearing part; 4) Place a supporting steel beam on the supporting part, and then lay wooden corrugated on it as a bottom form. The present invention solves the very difficult problem of supporting the bottom formwork of the cap platform due to the influence of the water level by setting the hanging basket, which can not only effectively avoid the influence of the water level, but also reduce the risk of operation safety and ensure the construction quality and construction progress. It has wide application and promotion value in wharf reconstruction projects.

Description

technical field [0001] The invention relates to a construction method of a wharf reconstruction project. Background technique [0002] With the rapid development of the country's economic construction, the problem of insufficient infrastructure capacity in the national industry and shipping industry has become increasingly prominent, seriously hindering the pace of high-speed and sustainable economic development. In the infrastructure of my country's coastal port areas, there are generally problems such as low load-bearing capacity of the wharf surface and insufficient dredging of the harbor basin, which make it difficult to dock large ships. resistance. Although it is possible to invest in the construction of a new wharf to alleviate the contradiction of this demand, there are many unfavorable factors: capital problems (huge investment); construction cycle problems (from project approval, demonstration, to design, construction period is very long); environmental factors ( ...

AI Technical Summary

Problems solved by technology

[0004] However, in these new technologies and new processes, the bottom form support technology and process method for the bottom surface of the cast-in-place cap below the water surface are relatively simple, and the general method is to weld the "corbel" underwater on the pile body of the existing pile. Or as a "hoop" method, as the load-bearing support part of the cap bottom form, such as figure 1 shown

Since the corbel welding part 4 is located at the bottom of the I-beam 3 below the cap bottom elevation 2, the safety risk of underwater operation is high, the construction efficiency is low, and it is easy to cause accidents such as electric shock and falling into the sea, which often cause construction damage. It is very difficult to increase the owner's capital investment
