Described step S2 comprises following steps:
Step S2.1, some foundation piles to be driven underground according to the position determined, to make the bottom of foundation pile enter strongly weathered sand-rock or middle weathered rock formation;
Step S2.2, bent cap to be bearing on some foundation piles of being located along the same line.
Described step S3 comprises following steps:
Step S3.1, some foundation piles to be driven underground, to make the bottom of foundation pile enter strongly weathered sand-rock or middle weathered rock formation;
Step S3.2, pile cover is fixedly connected on the top of foundation pile.
In described step S4, stake plate body abutment is on pile cover, and the dark beam support in termination of the stake plate body end of adjacent studs plate is on bent cap.
Described stake plate adopts the equal thickness steel concrete plate not having Vierendeel girder and secondary beam.
The present invention increases the degree of depth of foundation structure, strengthens the intensity of foundation structure, invariably based structures generation sedimentation, to the geological conditions above covering soft layer, overlaying bedrock, has good applicability and economy.

Detailed description of the invention
Following according to Fig. 1 ~ Fig. 5, illustrate preferred embodiment of the present invention.
The invention provides a kind of construction method of reinforcement type ground, for building reinforcement type foundation structure.
As shown in Fig. 2 ~ Fig. 5, described reinforcement type foundation structure comprises foundation pile structure and is arranged on the structural pile slab structure of foundation pile.
Described pile slab structure comprises some plates 2, described stake plate 2 comprises a plate main body 202 and is arranged on a dark beam 201 in the termination of plate main body 202 end, between adjacent studs plate 2, interval is arranged, form shrinkage joint 3 between stake plate, described stake plate 2 adopts the equal thickness steel concrete plate not having Vierendeel girder and secondary beam.
Described foundation pile structure comprises a plate and supports foundation pile assembly and stake plate gap support foundation pile assembly.
Described stake plate supports foundation pile assembly and is positioned at below a plate main body 202, and described stake plate gap supports foundation pile assembly and to be positioned between a plate below shrinkage joint 3.
Described stake plate supports foundation pile assembly and comprises the pile cover 102 that some foundation piles 101 and some correspondences are arranged on foundation pile 101 top, described foundation pile 101 is socketed pile, foundation pile 101 bottom enters strongly weathered sand-rock or middle weathered rock formation, described pile cover 102 is rigidly connected with foundation pile 101, pile cover 102 as the supporting seat of stake plate 2, supporting pile plate main body 202 together with foundation pile 101.
Described stake plate gap supports foundation pile assembly and comprises and be arranged on bent cap 103 between plate below the dark beam in shrinkage joint 3 and termination 201 and some foundation piles 101 be arranged on below bent cap 103, described foundation pile 101 is socketed pile, foundation pile 101 bottom enters strongly weathered sand-rock or middle weathered rock formation, the dark beam 201 in termination of adjacent two blocks of stake plates 2 is shelved on bent cap 103 simultaneously, the dark beam 201 in termination of foundation pile 101 supporting pile plate main body 202 end together with bent cap 103.As shown in Figure 1, the construction method of described reinforcement type ground comprises following steps:
Step S1, construction location according to the size determination foundation pile structure of pile slab structure;
According to the size at shrinkage joint between the stake plate needing between the size of pile slab structure king-pile plate and adjacent studs plate to reserve, determine that foundation pile structure king-pile plate gap supports the position of foundation pile assembly and stake plate support foundation pile assembly, guarantee that a plate gap supports a foundation pile assembly and to be positioned between a plate below shrinkage joint, guarantee that a plate supports a foundation pile assembly and is positioned at below a plate main body;
Step S2, according to the position determined, foundation pile assembly is supported to stake plate gap and constructs;
Step S3, according to the position determined, foundation pile assembly is supported to stake plate and constructs;
Step S4, stake plate is bearing in a plate gap and supports foundation pile assembly and stake plate supports on foundation pile assembly.
Described step S2 comprises following steps:
Step S2.1, some foundation piles to be driven underground according to the position determined, to make the bottom of foundation pile enter strongly weathered sand-rock or middle weathered rock formation;
Step S2.2, bent cap to be bearing on some foundation piles of being located along the same line.
Described step S3 comprises following steps:
Step S3.1, some foundation piles to be driven underground, to make the bottom of foundation pile enter strongly weathered sand-rock or middle weathered rock formation;
