TECHNICAL FIELD

[0001] The utility model belongs to the technical field of highway engineering, especially relates to a highway side slope expansion equipment. BACKGROUND

[0002] In highway construction and widening engineering, especially in rural low-grade highways, the demand for widening is increasing. However, these highways face many challenges during the widening process. On the one hand, due to land occupation restrictions and limited funds, the granite weathered rock mass that needs to be removed is usually thin, and the slope rate after trimming is steep, which increases the construction difficulty. On the other hand, the granite weathered rock mass is mainly composed of dense sand, although it is relatively easy to cut and remove with an intelligent drill, but the low-grade highway site is limited, and it is difficult for large excavation equipment equipped with an intelligent drill to enter the site for construction, and it is also difficult to maintain road traffic. Therefore, it is urgent to develop a light expansion equipment suitable for the thin layer of granite weathered layer section highway cutting slope, which can flexibly adjust to the excavation requirements of slopes with different slopes and heights, and realize accurate and stable excavation, and also meet the requirements of small land occupation area, maintaining road traffic during construction, and economic and suitable requirements.

With this arrangement, the telescopic support assembly can adjust the connection angle with the frame body according to the slope surface condition. When the slope rate is steep, the telescopic support assembly near the slope foot can be vertically arranged on one side of the slope foot, providing support force for the entire equipment, enhancing the stability of the equipment and improving the safety of the equipment.

[0007] Preferably, the telescopic support assembly comprises a support rod and a sleeve rod, the sleeve rod is internally provided with a receiving groove, one end of the support rod is connected to the lower part of the frame body, and the other end is slidably arranged in the receiving groove.
