Construction method of double-side wall guide pit composite stepped large-section tunnel excavation support
ActiveCN109057801ARealize the constructionAchieve secondary liningUnderground chambersTunnel liningSafety riskBack pressure
The invention provides a construction method of a double-side wall guide pit composite stepped large-section tunnel excavation support, which comprises the following steps: when a guide pit is excavated, the cross section of the guide pit is partially overlapped with the tunnel section along the longitudinal direction of the tunnel, a side wall is arranged in the guide pit, and the side wall is attached to the outer contour of the tunnel section; before the tunnel main hole is excavated, the tunnel slag back pressure backfill is carried out the guide pit and the tunnel core part, and the corresponding guide pit support structure is removed synchronously according to the excavation progress of the main hole during the excavation process of the main hole. The construction method has the advantages that the lateral deformation and bottom bulge deformation of the tunnel are prevented, the lining quality at the later stage of the tunnel is ensured, and the safety risk in large span and large section tunnel construction can be effectively controlled.

Annular embedded arrangement foundation used for shallow cover layers or bare rock areas in water
PendingCN107059914ASolve a series of problems faced by the applicationSimple structureCaissonsDouble wallEngineering
The invention discloses an annular embedded arrangement foundation used for shallow cover layers or bare rock areas in water. The annular embedded arrangement foundation comprises base grooves located in water bottom base rock, prefabricated open caissons and rock-socketed concrete. The bottom ends of the prefabricated open caissons are located in the base grooves. The space between the prefabricated open caissons and the base grooves is filled with the rock-socketed concrete. The base grooves are annular grooves vertically extending downwards. The shape formed after each annular groove is cut along the horizontal cross section is matched with the shape formed after each prefabricated open caisson is cut along the horizontal cross section. The annular embedded arrangement foundation is simple in structure and convenient to operate and use, advantages and disadvantages of traditional foundations in water are sufficiently taken into consideration in the annular embedded arrangement foundation, and by means of the technical measures of forming the annular grooves in the water bottom base rock, adopting the prefabricated double-wall steel open caissons and conducting post-pouring on the rock-socketed concrete, a series of problems faced by application of large-diameter deep hole drilling cluster pile foundations and open caisson foundations in the shallow cover layers and the bare rock areas are solved.
