Problems solved by technology

At present, the commonly used support systems include pile-anchor support system and composite soil nail wall support system, especially the composite soil nail wall support system, which is widely used in engineering because of its low price. The support system of composite soil nail walls is mostly vertical micro piles, the force of the support structure is not reasonable, and the cost is relatively high
In the prior art, there is no construction method and equipment that can quickly construct inclined piles, so that they can be applied to the panels of composite soil nail walls

Abstract

The invention relates to a batter pile construction drilling machine and a construction method, and can rapidly carry out the construction of batter piles inclined at needed angles. The invention adopts the following technical scheme: in the batter pile construction drilling machine, a rig is arranged on a base assembly, one end of the rig is rotatably connected with the base, the other end of the rig is a free end, moreover, an adjusting cylinder which is used for adjusting the angle between the rig and the base is arranged between the rig and the base, the rig is provided with a slip slide way along the length direction, a slip is matched with the slip slide way, and is connected with a drill tool, and two sets of drive pairs which are used for driving the drill tool to move along the length direction of the rig are respectively arranged on both sides of the rig. The method for carrying out construction by utilizing the batter pile construction drilling machine includes the following steps: (1) the rig is adjusted according to a designed angle until a drill bit reaches a designed depth; (2) a concrete pump or a mortar pump is started, so that a pile hole is filled up with concrete or mortar; (3) profile steels or a reinforcement cage are inserted into the concrete or mortar, so that a pile is formed; (4) the drilling machine is moved to the next pile position, and according to the sequence of the method, the piles are formed.

Description

technical field [0001] The invention relates to a construction method using a slanted pile construction drilling rig, which can quickly complete the construction of slanted piles with required angles, and belongs to the field of engineering construction. Background technique [0002] At present, in the reconstruction of old urban areas in urban construction, due to many factors such as the requirements of civil air defense, parking requirements of municipal facilities, high land prices, and urban planning height restrictions, basements are usually designed for new construction, reconstruction and expansion projects. Due to the influence of underground space and the protection requirements for adjacent buildings and underground municipal pipelines, the construction of foundation pits in basements generally requires strict design and construction of foundation pit support. At present, the commonly used support systems include pile-anchor support system and composite soil nail ...
