Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and the following embodiments.

[0022] The first aspect of the embodiments of the present invention provides a construction method for a prefabricated caisson, such as Figure 1-Figure 6 As shown, the caisson is spliced ​​by a plurality of sections 1, and the section 1 is divided into a bottom section 11, a middle section 12 and an upper section 13, and the middle section 12 and the upper section 13 are provided with grouting The hole 7 is vertically provided with a plurality of metal bellows penetrating along the middle section 12 and the upper section 13, and a penetrating steel rod channel 2 is formed in the metal bellows. The construction method includes the following steps:

[0023] Step 1, caisson design, precast segment 1;

[0024] Among them, caisson design includes: calculating the length of caisson and each section and the design elevation of caisson according...

Abstract

The invention provides a prefabricated assembly type open caisson, and relates to the technical field of open caisson construction. 1. The open caisson is formed by splicing a plurality of sections inthe vertical direction; a plurality of metal corrugated pipes penetrating through the sections are arranged along the sections in the vertical direction, penetrating steel bar channels are formed inthe metal corrugated pipes, stretched threaded steel bars are arranged in the steel bar channels, and the positions of the steel bar channels of two adjacent sections correspond to each other one by one; a concave square opening is formed in the position, corresponding to the corresponding steel bar channel, of the upper end face of each section, the upper end of the threaded steel bar in each section extends into the corresponding square opening, a steel bar connector is arranged in each square opening, the threaded steel bars of every two adjacent sections are spliced through the corresponding steel bar connector, and a grouting hole extending into each steel bar channel is formed in the side face of the corresponding section. According to the prefabricated assembly open caisson providedby the embodiment of the invention, the threaded steel bars 3 between the adjacent sections are tensioned, so that the sections are tightly attached and the integrity is good.

Description

technical field [0001] The invention relates to the technical field of sinking construction, in particular to an assembled caisson. Background technique [0002] The fabricated caisson is a caisson structure that replaces the cast-in-place reinforced 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 leakage prevention. In order to solve the above technical problems, the embodiment of the present invention adopts the following technical solutions to achieve: [0004] The invention provides a prefabricated assembled caisson, the caisson is vertically spliced ​​by several segments, and the segments are divided into a bottom segment, a middle segment and an upper segment; The...
