[0004] Conventional narrow foundation pit asphalt concrete core wall construction method: transport asphalt mixture and transition material by means of chute, hanging tank, and manual cart. Although the operation is simple, the construction speed is slow, and the temperature loss during the transportation of asphalt mixture is serious. The quality and safety of the asphalt concrete core wall cannot be effectively controlled

Embodiment Construction
[0026] The present invention is described in further detail below by embodiment, and embodiment is only used for illustrating the present invention, does not limit the scope of the present invention.
[0027] see Figure 1-7 A construction method for asphalt concrete core wall of a narrow foundation pit is shown, which is characterized in that it includes the following steps: setting water retaining sills 2 on the left and right banks of the core wall, setting sump 1 and water retaining stalk 3 upstream and downstream, setting Aggregation pit 6 for accumulating transition material; then use backhoe 8 to ride the base of the core wall and pave transition material from the right bank to the left bank. Ride the transition material to the right bank to pave the asphalt mixture;
[0028] 1) On the left and right banks of the base of the core wall, sandbags, mortar and block stones are used to set the water retaining sill 2. The water retaining sill 2 is 1.2m high and 7.5m long. Th...

The invention belongs to the field of asphalt concrete core wall construction of narrow foundation pits, and in particular relates to a construction method of asphalt concrete core walls of narrow foundation pits. It includes the following steps: setting water retaining sills on the left and right banks of the core wall, setting sump pits and water retaining stalks upstream and downstream, and setting aggregate pits for accumulating transitional materials at the upstream and downstream positions; Pave the transition material to the left bank, and use the loader to ride the transition material from the left bank to the right bank to pave the asphalt mixture. The invention effectively solves the problems of complex construction procedures, ensures the construction quality and safety, improves the construction speed of the asphalt concrete core wall, shortens the construction period, meets the construction period requirements of the asphalt concrete core wall, and realizes asphalt in narrow areas. Mechanized construction of concrete paving.
Description
technical field [0001] The invention belongs to the field of asphalt concrete core wall construction of narrow foundation pits, and in particular relates to a construction method of asphalt concrete core walls of narrow foundation pits. Background technique [0002] With the development of my country's hydropower industry, asphalt concrete core walls are widely used. Asphalt concrete core walls can adapt to various complex climatic conditions and have good anti-seepage effects. [0003] The construction of asphalt concrete core wall needs to consider the transportation equipment of asphalt mixture and transition material. For narrow foundation pits, the construction of asphalt concrete core walls is more limited by the water, pollution, transportation of mixture and transition materials during construction, and the safety of the foundation pit slope. [0004] Conventional asphalt concrete core wall construction methods for narrow foundation pits: transport asphalt mixture a...
