Problems solved by technology
The first reinforced concrete support is mostly constructed with cast-in-place concrete. The construction process is complex and slow, and the concrete support is a temporary structure. It needs to be chiseled out later and cannot be recycled, resulting in a large amount of redundant waste construction waste, which wastes resources and pollutes the environment; When the soil condition is good, steel support can be used for the second support and below, but when the soil condition is poor, it is necessary to design multiple concrete supports, but the existing problems are the same as the first concrete support

The invention belongs to the technical field of foundation pit engineering, and particularly relates to a foundation pit engineering prefabricated concrete non-first supporting system and a construction method thereof. The system comprises prefabricated concrete supports, prefabricated concrete waist beams, and enclosure structures. The prefabricated concrete waist beams are arranged at the innersides of the enclosure structures and supported on steel corbels, and the steel corbels are fixedly connected with the enclosure structures. The two ends of the prefabricated concrete supports are connected with the prefabricated concrete waist beams at the two sides of the prefabricated concrete supports through connecting joints respectively. The prefabricated concrete waist beams at one sides of the prefabricated concrete supports abut against the enclosure structures, the prefabricated concrete waist beams at the other sides of the prefabricated concrete supports abut against the enclosurestructures through steel plate wedges, and a concrete grouting material is poured between the prefabricated concrete waist beams and the enclosure structures. According to the foundation pit engineering prefabricated concrete non-first supporting system and the construction method thereof, the construction error and the installation error can be adjusted, and the two ends of the prefabricated concrete supports abut against the enclosure structures, so that the safety of a foundation pit is guaranteed, the poured concrete grouting material is convenient to chisel away in the later period, andthe recycling of prefabricated concrete elements is realized.
Description
technical field [0001] The invention belongs to the technical field of foundation pit engineering, and in particular relates to a foundation pit engineering prefabricated concrete non-first support system and a construction method thereof. Background technique [0002] The supporting retaining structure is mainly composed of soil retaining components and supports, and the most common soil retaining components are bored piles and underground diaphragm walls. The supporting retaining structure has clear force, and the calculation method and engineering practice are relatively mature. It is suitable for deep foundation pits under various geological conditions. It is currently the most widely used and relatively reliable supporting structure. At present, the first support in the supporting retaining structure is mostly supported by reinforced concrete. The support and the crown beam form a whole, which has strong deformation resistance and can avoid the overall damage caused by ...
