Problems solved by technology

Its disadvantages: when excavating the soil, the pile foundations are in an independent state and do not rely on each other, and the soil conditions around the pile foundations are very complicated, and some are very soft, which belongs to soft soil foundation
When the excavator enters the pile foundation site to excavate, due to the heavy weight of the excavator itself and the walking excavation, it is inevitable that the pipe pile will be displaced, damaged and damaged due to improper excavation.

Embodiment 1

[0011] Embodiment 1: with reference to attached Figure 1~3 . The fast excavation system is characterized in that it is made of upper rail 1, lower rail 3 and excavator 5, and the processing and manufacturing of upper rail 1 and layer rail 3 are prior art, so it will not be described here. Roller 2 is equipped with at the bottom of upper track 1, and the processing manufacture of this roller is prior art, does not describe here. The roller 2 is located on the lower track 3 and can move back and forth or left and right along the lower track 3. The lower track 3 is located at (fastened or installed on) the end face of the concrete pipe pile 4. The excavator 5 is the prior art, and its bottom is equipped with The roller 2 is also positioned on the upper track 1, and is intended to move back and forth or left and right along the upper track 1.

Embodiment 2

[0012] Embodiment 2: On the basis of Embodiment 1, the upper track 1 can be two or more tracks. If it is a track, the running wheels of its excavator 5 must be rollers that match the track. If the upper track If it is a slat, then the road wheels of the excavator 5 can be tires or crawlers. The lower floor track 3 can be two tracks or a plurality of tracks, and its upper floor track 1 runs on it by rollers.

Embodiment 3

[0013] Embodiment 3: on the basis of embodiment 1, with reference to appended image 3 . The excavation method of the fast excavation system, the lower track 3 is installed on the end face of the concrete pipe pile 4, the upper track is located on the lower track and is movable, (1) when the roller on the back of the upper track 1 moves back and forth along the lower track 3 or left At the same time, the upper track 1 drives the excavator 5 located therein to move back and forth or left and right synchronously. , The excavator 5 moves back and forth or left and right along the upper rail (or slat).

Abstract

The invention relates to a system for quick digging after completion of pile foundation and a digging method, and the system consists of an upper layer of a track, a lower layer of a track and a digging machine. The bottom of the upper layer of the track is provided with an idler wheel which is positioned on the lower layer of the track, the lower layer of the track is arranged on the pile foundation, and the bottom of the digging machine is provided with an idler wheel which is positioned on the upper layer of the track. The device has the advantages: 1. having novel, unique, simple and practical structural design; 2. avoiding the problems of derivation, breakage and damage of the pile foundation caused by directly applying the digging machine to a construction site of the pile foundation so as to fundamentally ensure safety in a process of digging of the pile foundation, ensure construction quality and make clear responsibility of construction dispute; and 3. having high digging efficiency and low cost to ensure construction period.

Description

technical field [0001] The invention relates to a soil excavation system and a soil excavation method after pile foundation is completed, and belongs to the field of construction engineering equipment manufacturing. Background technique [0002] After the existing pile foundation is completed, when excavation is required, the excavator is driven into the pile foundation construction site for digging. Its disadvantages: when excavating, the pile foundations are in an independent state and do not rely on each other, and the soil quality around the pile foundations is very complicated, and some are very soft, which belongs to soft soil foundation. When the shovel enters the pile foundation site to dig, because the weight of the shovel itself is very heavy, and the walking excavation, it is inevitable to cause deviation, breakage and damage of the pipe pile due to improper digging. Contents of the invention [0003] Design purpose: To avoid the deficiencies in the background ...
