Embodiment Construction

[0042] see Figure 1-4 As shown, those skilled in the art should understand that, in the disclosure of the present invention, the orientation or positional relationship indicated by the terms "upper", "lower", etc. are based on the orientation or positional relationship shown in the drawings, which are only for It is convenient to describe the present invention and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, so the above terms should not be construed as limiting the present invention.

[0043] It should be noted that during the construction process, the gravel layer was placed and the plain concrete was poured to prevent further subsidence. Since the concrete takes a long time to solidify, the plain concrete and the caisson are not integrated at this time, and the caisson has no effect on the soil at the bottom. If the pressure is high...

Abstract

The invention relates to a method for open caisson quick bottom sealing. The method includes the following steps that an open caisson is sunk to a working position; and a prefabricated bottom plate ismounted at the bottom of the open caisson. When the method of the embodiment is used, the prefabricated bottom plate is mounted at the bottom of the open caisson after the open caisson is sunk to theworking position, in the construction process, when the bottom of the open caisson is sealed, the bottom sealing process of the open caisson can be directly completed after the prefabricated plate ismounted in the open caisson, due to the fact that the bottom of the open caisson has soil, resistance to the prefabricated plate can be generated, thus preventing the whole open caisson from sinking,operation of the open caisson is completed, compared with the concrete sealing process, the bottom sealing speed is fast, water can be effectively prevented from entering the open caisson, at the same time, concrete does not need to be solidified in the well, collapse caused by the erosion of the concrete by groundwater is avoided, quality and safety of a project are ensured, at the same time, gravel layers do not need to be padded, and the construction cost is saved.

Description

technical field [0001] The invention relates to a method for controlling a caisson, in particular to a method for quickly sealing the bottom of a caisson. Background technique [0002] Building caissons in unfavorable formations is the most commonly used construction method. The construction method of caissons is to dig in the caissons while sinking under the cover of the caissons to sink the caissons to the working position. During well construction, sealing the bottom of the caisson is the key to the construction of the caisson, because when the caisson sinks to the construction site, there will be soil, water and other substances in the construction site, and the soil will be relatively loose, which will cause the caisson to continue to sink. In the existing way, after the caisson sinks to the construction position, the crushed stone layer is first cushioned, and then plain concrete is poured to suppress the groundwater. [0003] However, during the construction process,...
