Detailed Description
The following detailed description of the present invention is provided to facilitate further understanding of the invention.
The utility model provides a piping lane open cut foundation ditch lateral wall crosses retaining structure of branch pipeline ditch, encloses purlin 1, slip casting anchor pipe 2 and reinforcing bar net piece 3 including shaped steel. In detail:
shaped steel encloses 1 foundation ditch trend of purlin and transversely separates the setting, and slip casting anchor pipe 2 passes shaped steel and encloses 1 of purlin and insert the soil body 4, and reinforcing bar net piece 3 sets up on the foundation ditch lateral wall.
Further, the profile steel purlin 1 is connected with the drilling piles at two sides of the branch pipe trench. The shaped steel encloses purlin 1 and separates the setting, and the interval between upper and lower adjacent shaped steel encloses purlin 1 is 1.5 m. The length of the grouting anchor pipe 2 is 6-8m, and a plurality of grout overflow holes are formed in the pipe wall. The reinforcing mesh 3 is a reinforcing mesh of phi 6@100 x 100.
A pipe gallery open cut foundation pit side wall soil retaining method crossing branch pipe ditches comprises the following steps:
(1) firstly, completing construction of main pipe gallery foundation pit bored pile enclosure structures on two sides of an existing branch pipe trench, constructing pile top crown beams 6, and integrally connecting the crown beams 6 on the upper part of the branch pipe trench;
(2) excavating main line pipe gallery foundation pits at the branch pipe ditch in layers, wherein the excavation depth is 1.5m each time, arranging 1 transverse section steel surrounding purlin 1, and reliably connecting the transverse section steel surrounding purlin 1 with drilled piles 5 at two sides of the branch pipe ditch; a grouting anchor pipe 2 is driven into the side wall of the foundation pit, a plurality of grout overflow holes are formed in the pipe wall of the grouting anchor pipe 2, a reinforcing mesh 3 is hung after grouting is injected into the grouting anchor pipe 2, and concrete is sprayed;
(3) and repeating the steps to excavate to the pit bottom.
Preferably, the grouting anchor pipe in the step (2) is a phi 42 grouting anchor pipe with the length of 6-8 m. The slurry overflow hole is a phi 8 slurry overflow hole, and the grouting pressure is 0.5 MPa. The reinforcing mesh is phi 6@100 multiplied by 100. The concrete is C20 concrete.
