Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit construction, in particular to a slope protection pile and anchor rod connection structure. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to make the earth slope stable. The slope size is determined according to relevant construction regulations. If the excavation is deeper and there are buildings nearby, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored cast-in-place pile interlocking methods to prevent the outer soil layer from collapsing.

[0003] The construction of slope protection piles and anchor rods is a common support method for foundation pits. The connection between anchor rods and slope protection piles is basically a pad nut connection. The inclined anchor rods and the vertical slope protection piles pass through pads and nuts, which will cause a gap between the pads and the slope protection piles. Therefore, we designed a connection structure between slope protection piles and anchor rods, using adjustable wedge blocks between the pads and the slope protection piles. After the nuts are tightened, the adjustable wedge blocks are moved up to make the connection between the anchor rods and the slope protection piles more secure. Utility Model Content
