Soil lifting system and soil lifting method for building deep foundation pit construction in narrow area

Abstract

The invention discloses a soil lifting system and soil lifting method for building deep foundation pit construction in a narrow zone. A large closure plate is adopted on a first concrete support around a hole as a first closure plate for arrangement of soil lifting equipment and a soil heap platform. A steel headframe soil lifting crane is adopted in the vertical soil lifting equipment and comprises a steel headframe erected on the hole and electric blocks suspended on the steel headframe. The soil heap platform is arranged on the first closure plate around the hole and is an area defined by a retaining wall and a water retaining bank. The large closure plate is adopted on the first concrete support around the hole as the first closure plate, a conveying channel is provided for a conveying vehicle, a material storage yard is provided for subsequent construction of a main structure, and a field is provided for mounting of the soil heap platform and the steel headframe. A soil heap area is arranged on the first closure plate, and used for temporally piling up earthwork which cannot be conveyed out in time. The steel headframe soil lifting equipment is adopted, the limit of field reinforced concrete ramps is avoided, the soil outlet path is increased, the construction period is greatly shortened, and the method is especially suitable for narrow-field deep foundation pit construction.

Description

technical field [0001] The invention relates to the technical field of earthwork excavation construction, in particular to a soil lifting system and a soil lifting method for building deep foundation pit construction in a narrow area, which are applied in the construction of circular buildings with narrow construction spaces. Background technique [0002] At present, in the construction of deep foundation pits of ring buildings with narrow construction space, two problems are usually faced. On the one hand, due to the small site, large internal support area, small clear distance between supports, it is difficult to excavate the earthwork under the support, and it cannot be excavated according to the conventional method. On the other hand, due to the lack of material storage yards, earth moving vehicles have to drive to the bottom of the foundation pit to transport earth, which cannot be transported outside during morning and evening traffic peaks and rainy days, and the const...

Problems solved by technology

[0003] The purpose of the present invention is to provide a soil lifting system and soil lifting method for building deep foundation pit construction in narrow areas, so as to solve the problem of small site, large internal support area, small net distance between supports and earthwork under supports in the construction of narrow areas in the prior art. Excavation is difficult, there are few excavation paths, and the technical problems that earth excavation cannot be completed by grading in the conventional way, and due to the lack of material storage yards, earth-moving vehicles need to drive to the bottom of the foundation pit to transport earth, and cannot go outside during morning and evening traffic peaks and rainy days The construction progress was hindered during transportation, and the technical problems of greatly prolonging the construction period
