Abstract

The invention provides a construction method of a prefabricated assembly type open caisson, and relates to the technical field of open caisson construction. The open caisson is formed by splicing multiple sections. The construction method comprises the following steps of 1, designing the open caisson and prefabricating sections; 2, leveling a field, mounting a bottom section at the open caisson position determined in advance, and excavating soil below at the position of the open caisson; 3, mounting a middle section or an upper section in an aligning manner, and anchoring temporarily; 4, continuing to excavate the soil below until a next section is higher than the ground by a preset distance; 5, repeating the step 3 and the step 4 until the mounting of all the sections is finished; 6, grouting and performing anchor sealing in a steel bar channel; and 7, continuing to excavate the soil below, and enabling the open caisson to sink until the open caisson sinks to the design elevation. Theconstruction method is high in construction speed and reliable in construction quality, reduces the pollution to the surrounding environment, includes temporary anchoring and permanent anchoring in the splicing process of the sections, enhances the open caisson integrity, and is high in safety performance.

Description

technical field [0001] The invention relates to the technical field of caisson construction, in particular to a construction method for a prefabricated assembled caisson. Background technique [0002] The prefabricated caisson is a caisson structure that replaces the cast-in-place concrete caisson. At present, most of the prefabricated caissons are connected by bolts, which often weakens the integrity of the prefabricated caisson structure and is prone to leakage. Contents of the invention [0003] In view of the above technical problems, the present invention aims to provide a prefabricated caisson with good sealing effect and anti-leakage and its construction method. In order to solve the above technical problems, the embodiment of the present invention adopts the following technical solutions to achieve: [0004] The first aspect of the present invention provides a construction method for a prefabricated caisson. The caisson is formed by splicing a plurality of segmen...
