Description
Technical Field
The utility model relates to the technical field of excavation supporting construction of underground infrastructure, in particular to a grooving machine power head mechanism.
Background
The construction of infrastructure such as civil engineering, water conservancy, mines, municipal works and the like in China achieves remarkable achievement. In the processes of underground space development and utilization, mineral resource exploitation and the like, when complex geological conditions are faced, slope support or foundation pit support measures are often required to be adopted so as to ensure the safety and stability of the underground engineering construction process and the surrounding environment in the process. With the development of geotechnical engineering technology, machinery, civil engineering materials and the like, side slope support and foundation pit support technology are effectively developed, and correspondingly support structure systems such as soil nailing walls, composite soil nailing walls, underground continuous walls, row pile supports, pile anchor supports and the like which take traditional building materials such as sand stone, cement, steel bars, concrete and the like as structural main bodies are developed. Meanwhile, in order to control the influence of underground water on the supporting structure and the underground engineering construction, a waterproof curtain is considered to be arranged in a supporting system or a dewatering measure is taken into consideration. Especially under the circumstances that the groundwater level is higher, the side wall soil layer is softer and is easy to disturb, foundation pit support must consider to take groundwater treatment measures such as precipitation or stagnant water. By adopting a reasonable soil-retaining and water-stopping mode, the safety of surrounding buildings, structures and underground pipelines can be ensured, and in more cases, the creep of the soil body of the side wall induces accidents such as surrounding earth surface cracks, uneven settlement of the buildings and the like. The current inter-pile waterproof curtain adopts cement-soil technical measures such as a stirring pile, a high-pressure jet grouting pile, a TRD construction method pile, a biting pile and the like, and after the depth of the waterproof curtain is increased, although corresponding engineering measures are adopted, leakage risks caused by defects still exist, and in addition, the waterproof curtain can be cracked due to excavation deformation of a foundation pit. However, from the essence of the foundation pit support, the foundation pit support is taken as a measure for protecting the construction of the underground main body structure and the surrounding environment, and temporary support, reinforcement and protection and groundwater control are adopted, and the deeper the foundation pit is, the more complex the surrounding environment is, the higher the construction cost of the foundation pit engineering is, more importantly, the service life of the foundation pit is generally not more than 2 years, and the foundation pit is abandoned or dismantled after the construction of the underground main body structure is finished, so that the construction cost of the foundation pit engineering is very expensive compared with that of the main body engineering. Even if a few foundation pits at present adopt the design of integrating the supporting structure and the underground main body structure, under the condition, the construction efficiency of the subsequent foundation engineering is reduced, the labor cost is greatly increased, the potential risk of leakage of the subsequent construction joint is very high, and the treatment of weak parts and verticality deviation of the subsequent underground continuous wall caused by the construction process and concrete pouring is very difficult.
Therefore, a flexible composite assembled recoverable foundation pit supporting structure process (refer to patents such as CN201710396002.0, CN201710396035.5 and CN201811095721. X) is invented on the basis of various comprehensive schemes by a team beginning with Wang Fuming institutions, the defects of the existing process are overcome, the construction speed can be greatly improved, the cost is saved, supporting piles are required to be continuously arranged at preset positions, slotted holes are reserved among the piles to connect adjacent supporting piles, and then a retaining water stop plate is installed in the slotted holes, and finally backfilling is carried out.
The main construction operation difficulty of the technology is that the digging of the embedded holes of the support piles and the digging of the slotted holes among the piles are completed by using the existing drilling machine, while the traditional grooving equipment is designed aiming at the original construction technology, has low construction efficiency when being applied to the new technology, and limits the popularization and application of the new technology.
The utility model designs a cutter head structure of a grooving machine driven by double shafts, adopts a double-drill rod driving structure, drives 6 cutter heads to rotate and undercut, can effectively crush an underground soil layer, stably undercut, and greatly improves grooving efficiency and quality, and a traditional cutter head mechanism can only drive one drill rod, so the utility model designs a novel cutter head mechanism capable of simultaneously driving two drill rods.
