Embodiment 1

[0046] see Figure 1 to Figure 7 , this embodiment discloses a suspended excavation device for two-way synchronous reverse construction, including: a transport box 5 for loading waste, a long-distance horizontal transport device and a suspended crane. The long-distance horizontal transport device can transport the transport box 5 to a designated loading point to unload waste and transport the empty transport box 5 back. The suspended crane is hung below the bottom of the structural floor beam of the first floor above the ground and straddled above the unearthed reserved hole on the ground floor. The suspended crane can place the transport box 5 on the structural floor of each underground floor. vertically lift in the unearthed reserved hole, and can move the transport box 5 horizontally, so that the transport box 5 is placed on the long-distance horizontal transport device or lifted away from the long-distance horizontal transport device.

Embodiment 2

[0057] read on Figure 1 to Figure 7 , this embodiment discloses the construction method of the suspended excavation device used for bidirectional synchronous reverse construction as described in Embodiment 1, including the following steps:

[0058] Step 1: Start construction on the basement roof B0 as the ground floor. After the concrete is cured to the strength requirements, start the two-way construction of the structural floor B1 of the first floor in the basement downwards and the structural floor F1 of the first floor above the ground upwards. The same position on the floor of the multi-storey structure corresponds to setting a reserved hole for excavation.

[0059] Step 2: After the structural floor F1 of the first floor above the ground is maintained until the strength meets the requirements, the suspension bracket 4 is installed at the bottom of the structural floor beam of the first floor above the ground above the reserved opening, and the suspension bracket 4 is co...

Abstract

The invention provides a hanging type unearthing device for bidirectional synchronous reversed construction and a construction method. A conveying box, filled with wastes produced by basement construction, is lifted out of the ground and transferred onto a long-distance horizontal conveying device through a hanging type crane and then is conveyed to an appointed loading position by utilizing the long-distance horizontal conveying device, the wastes in the conveying box are unloaded into a conveying vehicle by utilizing other cranes, and the empty conveying box is put onto the long-distance horizontal conveying device again, then conveyed back through the long-distance horizontal conveying device and finally conveyed to a basement through the hanging type crane for repeated use. With the adoption of the hanging type unearthing device and the construction method, the cleaning and conveying efficiencies of underground engineering wastes can be effectively improved, the investment of large machines near an unearthing reserved hole in an underground structure is effectively reduced, the construction cost is lowered, and the influence of underground waste cleaning and conveying construction on upper part structure construction can also be greatly lowered.

Description

technical field [0001] The invention belongs to the field of civil construction, and in particular relates to a suspended excavation device and a construction method for two-way synchronous reverse construction. Background technique [0002] In traditional deep foundation pit engineering, the earthwork is cleared and transported by excavators, the temporary concrete support, and the staging wall are cleaned and transported by cranes. This method is suitable for working conditions with open construction operations. However, at present, the development scale of the foundation pit engineering in the central area of ​​the city is getting deeper and larger. In order to control the deformation of the foundation pit, the method of separate pit construction is often adopted. Due to the removal of temporary supports and phased walls, a large amount of solid waste will be brought , In addition, there are a large number of deep foundation pits that are constructed by the reverse method...
