Embodiment Construction

[0029] Attached below Figure 1-3 The present invention is described further:

[0030] Take the basement four floors as an example:

[0031] The general column grid size of the project is 8 meters x 16 meters, and the building size is 140 meters x 70 meters. According to the calculation of construction period and total earthwork, it is divided into 3 sections, each section is about 50 meters long, and a set of independent conveyor belt systems are set up.

[0032] see figure 1 As shown, the earthwork vertical transportation method of reverse method construction of the present invention, it adopts the sectioned belt type conveyor belt as the tool of earthwork vertical transportation, installs the conveyor belt through the technical reserved hole on each floor, and the earthwork is directly connected to the road by the conveyor belt. On the dump truck, the specific construction steps are as follows:

[0033] Step 1: First, carry out the construction of site maintenance struc...

Abstract

The invention relates to a device and a method for vertically transporting earthwork by a reverse construction method, which belong to the field of civil construction. In the device, segmental belt-type conveyor belts are adopted as earthwork transporting tools in a deep foundation pit; the conveyor belts pass through reserved holes of floor slabs on each floor; and the earthwork is transported to a dump truck obliquely from the bottom to the top by the conveyor belts. The device is formed by connecting independently segmented and obliquely arranged belt-type conveyor belts end to end; and each floor is provided with at least one conveyor belt which consists of an electric motor, a conveyor belt rack, an unloading tank, a scraping plate, a roller wheel, a roller wheel shaft bracket, a belt, a feeding funnel and an emergency brake device. The device and the method for vertically transporting the earthwork by the reverse construction method can effectively increase the earth volume in single vertical transport, effectively improve excavation efficiency, reduce excavation machines, reduce excavation cost, and simultaneously, reduce the influence of the construction of underground excavation on the simultaneous construction of an upper structure to the minimum.

Description

technical field [0001] The invention relates to a device and a method for earthwork transportation of deep foundation pits in construction engineering. Background technique [0002] At present, in the reverse construction of deep foundation pits, the key to restricting the construction period is the speed of earthwork transportation. Most of the top-down projects use long-arm excavators, crawler grab shovels or gantry cranes to excavate directly from the excavation hole. Since the long-arm excavator or crawler grab shovel near the excavation hole needs to be rotated when lifting and loading soil, it needs a large operating space, and large machinery and vehicles need to go up the floor. The above excavation methods are mainly suitable for the excavation of basements with podiums, or semi-inverted projects. [0003] When the land occupied by the above-ground part is almost the same as that of the underground part, due to the limitation of the height of the first floor, the ...
