A kind of reverse construction mechanical device

Abstract

The invention discloses a reverse building method construction mechanical device. The reverse building method construction mechanical device comprises a main tank and caterpillar bands, wherein an earth cutting idler wheel is arranged at one end of the main tank; a crushed earth collection device is arranged below the earth cutting idler wheel; an earth pumping and discharging device is arranged at the other end of the main tank; earth is discharged out through the earth pumping and discharging device; crushing tool edges are arranged at the bottom end and the front end of the crushed earth collection device; and a tank conveying device is arranged inside the crushed earth collection device. The reverse building method construction mechanical device has the characteristics of being small in size, flexible and efficient, and greatly reduces the construction difficulty; the added construction amount caused by underground height limitation can be avoided as much as possible; and reserved construction openings or the construction amount and construction expenses needed for reinforcing the reserved construction openings can be reduced as much as possible.

Description

technical field [0001] The invention relates to a novel construction machine design of reverse method. Background technique [0002] Reverse method: first construct the underground diaphragm wall or other supporting structures along the axis of the basement of the building or around it, and at the same time pour or lay down the intermediate supporting piles and columns at the relevant positions inside the building, as a way to bear the self-weight and construction of the upper structure before the bottom plate is sealed during the construction period. load support. Then construct the beam-slab floor structure on the first floor as the support of the underground diaphragm wall with high rigidity, and then excavate the earthwork and pour the underground structure of each layer layer by layer until the bottom plate is sealed. At the same time, since the floor structure of the ground floor has been completed, conditions have been created for the construction of the upper struct...

Problems solved by technology

[0011] ① Digging problem: Due to the height limit of the underground layer, small excavating machines are required or manual excavation is required

However, under normal circumstances, there is often a lack of small machinery, so we can only rely on large machinery and manpower to excavate the soil. Large machinery is inconvenient to use, and the efficiency of manpower excavation is not high. We can only make up for it with crowd tactics, which take up 24 hours. At the expense of labor costs

Excavation is carried out with the top closed, and there are a certain number of intermediate support columns and well point pipes for dewatering distributed in the foundation pit. There is still a lack of small, flexible and efficient small excavation machines, which makes excavation more difficult.

[0012] ②Underground floor height limitation: The support position of the reverse method is limited by the basement floor height, and the height cannot be adjusted. In case of a basement with a large floor height, it is sometimes necessary to set up temporary horizontal supports or increase the section and reinforcement of the enclosure wall

[0013] ③Reinforcement of construction openings: If the "closed reverse method" is adopted, one or two large construction openings need to be reserved at the floor for the transportation of earth and materials during downward construction to ensure construction The normal operation of the mouth must be reinforced afterwards, which requires a certain fee
