Pre-buried anchor rod connecting structure penetrating through pre-built building and construction method thereof

Abstract

The invention discloses a pre-buried anchor rod connecting structure penetrating through a pre-built building and a construction method thereof. The connecting structure comprises a pre-built mattress layer connected to the lower portion of a pre-built foundation, a foundation reinforcing pile connected to the interior of a soil body below the pre-built mattress layer, a top beam connected to the top of a supporting pile, an anchor rod free section connected to the interior of the top beam and the interior of the pre-built mattress layer in a penetrating mode in advance, an anchor rod connected to the tail end of the anchor rod free section and connected to the lower portion of the existing ground, and a cement grouting body connected to the periphery of the anchor rod in a sleeving mode. According to the pre-buried anchor rod connecting structure penetrating through the pre-built building and the construction method thereof, through arrangement of the cement grouting body, a foundation is provided for anchoring advantageously; the anchor rod obliquely extends downwards, and thus anchoring force can be provided in the maximum range; through arrangement of the anchor rod free section, the early-stage anchoring effect can be ensured; and through arrangement of an anchoring conversion piece and an elastic pipe, stress transmission, transition and protection of anchoring of the anchor rod are facilitated. According to the pre-buried anchor rod connecting structure penetrating through the pre-built building and the construction method thereof, construction of the pre-built building is not affected, and the influence of too much construction period and construction cost on a later-period adjacent foundation pit excavation project is avoided.

Description

technical field [0001] The invention belongs to the technical field of bolt construction, and in particular relates to a pre-embedded bolt connection structure passing through pre-built buildings and a construction method thereof. Background technique [0002] At present, with the rapid development of urban construction, urban land is becoming more and more scarce. In order to fully improve the utilization rate of underground space, the underground part of high-rise buildings is also increasing, and the foundation pits are also getting bigger and deeper. Bolt technology is an efficient and economical rock-soil reinforcement technology, which has been widely used in deep foundation pit engineering of buildings. However, in actual building construction, when the foundation pit is excavated after the building is built first, if the foundation pit adopts technologies such as supporting piles and geographic treatment, it is not conducive to the layout of anchor rods; using other ...
