Abstract
A reinforced foundation structure comprises a foundation pile structure and a pile plate structure arranged on the foundation pile structure. The pile plate structure comprises a plurality of pile plates. Each pile plate comprises a pile plate body and an end hidden beam arranged at the end of the pile plate body. Every two adjacent pile plates are arranged in a spaced mode to form an inter-pile-plate expansion joint. The foundation pile structure comprises a plurality of pile plate supporting foundation pile assemblies arranged below the pile plate bodies and a plurality of pile plate gap supporting foundation pile assemblies arranged below the inter-pile-plate expansion joints and the end hidden beams. Each pile plate supporting foundation pile assembly comprises a plurality of foundation piles and a plurality of pile caps correspondingly arranged at the top ends of the foundation piles. Each pile plate gap supporting foundation pile assembly comprises a cap beam and a plurality of foundation piles arranged below the cap beam, wherein the cap beam is arranged below the corresponding inter-pile-plate expansion joint and the corresponding end hidden beam. The foundation piles are rock socketed piles. The bottom ends of the foundation piles enter a strong weathered rock stratum or an intermediary weathered rock stratum. The depth of the foundation structure is increased, the strength of the foundation structure is improved, and the foundation structure is prevented from subsiding.
Description
Technical field
The present invention relates to a kind of reinforcement type foundation structure.
Background technology
Existing pile foundation reinforcement ground pattern, be mainly mini pile and reinforce, pile body diameter is not more than 300mm, generally presses composite foundation treatment, foundation soil and stake shared upper load.To the geological conditions above covering soft layer, overlaying bedrock, under load action, still a certain amount of sedimentation can occur, the engineering tight and very high to ground deformation requirements for some durations, is difficult to meet the demands.
Summary of the invention
The invention provides a kind of reinforcement type foundation structure, increase the degree of depth of foundation structure, strengthen the intensity of foundation structure, invariably based structures generation sedimentation.
In order to achieve the above object, the invention provides a kind of reinforcement type foundation structure, comprise foundation pile structure and be arranged on the structural pile slab structure of foundation pile;
Described pile slab structure comprises some plates, and described stake plate comprises a plate main body and is arranged on a dark beam in the termination of plate body end, and between adjacent studs plate, interval is arranged, and forms shrinkage joint between stake plate;
Described foundation pile structure comprises some stake plates be arranged on below a plate main body and supports foundation pile assembly and some stake plate gap support foundation pile assemblies be arranged between a plate below the dark beam in shrinkage joint and termination;
Described stake plate supports foundation pile assembly and comprises the pile cover that some foundation piles and some correspondences are arranged on foundation pile top;
Described stake plate gap supports foundation pile assembly and comprises and be arranged on bent cap between plate below the dark beam in shrinkage joint and termination and some foundation piles be arranged on below bent cap;
Described foundation pile is socketed pile, and foundation pile bottom enters strongly weathered sand-rock or middle weathered rock formation.
Described stake plate adopts the equal thickness steel concrete plate not having Vierendeel girder and secondary beam.
Described pile cover and foundation pile are rigidly connected, pile cover as the supporting seat of stake plate, supporting pile plate main body together with foundation pile.
The dark beam in termination of adjacent two blocks of stake plates is shelved on bent cap simultaneously, the dark beam in termination of foundation pile supporting pile plate body end together with bent cap.
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. 4, illustrate preferred embodiment of the present invention.
As shown in Figure 1 to 4, the invention provides a kind of reinforcement type foundation structure, comprise foundation pile structure and be 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.
Bottom due to foundation pile enters strongly weathered sand-rock or middle weathered rock formation, the bottom displacement of foundation pile is negligible, do not consider that at the bottom of cushion cap, load shared by foundation soil, the settling amount that the subsidiary stress that the following foundation soil of bottom plane of foundation pile is caused by foundation pile produces is negligible, the final settlement of pile foundation only needs to consider Pile shaft conpression, therefore sedimentation is substantially reduced, the present invention adopts pile cover further, bent cap and stake plate are reinforced foundation pile, invariably based structures generation sedimentation, to on cover soft layer, the geological conditions of overlaying bedrock, there are good applicability and economy.
Although content of the present invention has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
