Abstract: The present invention discloses a construction treatment method for reinforcing deep peat soil 
foundation, by laying grouting holes along the deep peat soil foundation, laying a plurality of 
shallow holes for inserting short grouting pipes and a plurality of deep holes for inserting long 
grouting pipes, injecting grout into the short grouting pipes to form a composite foundation 
reinforcement platform, injecting grout into the long grouting pipes to form a composite pile 
foundation, while laying reinforcing holes along the deep peat soil foundation, laying a 
plurality of shallow holes for inserting short reinforcing bars and a plurality of deep holes for 
inserting long reinforcing bars, and using a pipe insertion machine to insert reinforcing bars 
into the shallow holes for reinforcing bars and the deep holes for reinforcing bars to form a 
composite pile foundation. The reinforcement pile foundation is formed by inserting 
reinforcing bars into the shallow holes and deep holes with long reinforcing bars, and 
reinforcing pile foundation is strengthened by using composite pile foundation and reinforcing 
pile foundation to enhance the compressive strength of soil body and significantly improve the 
bearing capacity of deep peat soil foundation.

S1001: survey the surrounding area of deep peat soil foundation, obtain 
the nature of the area where the foundation is located, determine the 
ground reinforcement or underground reinforcement, determine the area 
of deep peat soil foundation, and prepare reinforcement materials and 
tools according to the area of deep peat soil foundation; 
S1002: remove the surface vegetation ofthe deep peat soil foundation, 
then lay bamboo basketry as a working cushion, cover the working 
cushion with soil layer, and tamp the soil layer as the working base of 
tamping machine and intubation inachine, and at the same time, use 
landfill and tamp fine stone layer to lay the -shaped road within the 
scope of the deep peat soil foundation 
S1003: grouting holes are arranged along the deep peat soil foundation, 
and a plurality of shallow grouting holes with short grouting pipes and 
deep grouting holes withlong grouting pipes are arranged: Grouting is 
carried out into the short grouting pipes to form a composite foundation 
reinforcement platform, and grouting is carried out into the long grouting 
pipes to form a composite pile foundation 
S1004: laying steel bar holes along the deep peat soil foundation, laying a 
plurality of shallow steel bar holes with short steel bars and deep steel bar 
holes with long steel bars, and implanting steel bars into the shallow steel 
bar holes and deep steel bar holes by adopting an intubation machine to 
form a reinforcing pilefoundation; 
31005: under the action of gravity, the deep peat soil foundation is 
compacted by a tampMg machine, and the soil pores of the deep peat soil 
foundation are compressed; finally, a sand cushion layer is laid on the 
surface of the deep peat soil foundation, and the deep peat soil foundation 
is reinforced after the compaction is continued.
