Abstract
The utility model discloses a foundation pit supporting structure, comprising an underground diaphragm wall, an anchoring pile and a beam column. One end of the beam column is arranged at the top of the anchoring pile, and the other end of the beam column is arranged on a top beam of the underground diaphragm wall. The anchoring pile is arranged at the outer side of the underground diaphragm wall. According to the foundation pit supporting structure disclosed by the utility model, a combined structure of the underground diaphragm wall, the anchoring pile and the beam column is adopted, so that an inner supporting and anchoring rod is prevented from being arranged. The foundation pit supporting structure is applicable to various geological conditions. Therefore, the flexural rigidity of the underground diaphragm wall can be improved; the capability of resisting soil body lateral pressure, which is increased according to a foundation pit digging depth, is enhanced; the displacement is reduced; and the construction cost is decreased. Meanwhile, the dipping depth can be increased and the possibility of occurring overturning damage is reduced.
Description
Technical field
The utility model relates to a kind of foundation pit supporting construction.
Background technology
Diaphragm wall is a foundation pit supporting construction system of building deep foundation engineering and underground structure.It is big that it has wall rigidity, and intensity is high, can keep off soil, load-bearing, intercept water impervious and advantage such as good endurance, distortion be little, can be used for constructing under the various complex site conditions.Support form at present commonly used have cantilevered, with soil bolt combined type, inner supporting type, contrary sequence method formula etc.But big and excavation is not deeply at some foundation ditch areas, suitable engineering of establishing anchor pole or interior support supporting, adopts conventional supporting and protection structure comparatively improper.
The utility model content
The utility model technical issues that need to address provide a kind of foundation pit supporting construction, and its influence to the building of periphery and soil layer construction is less, also can not influence soil excavation and main structure construction, is suitable for multiple geological conditions.
The utility model solves the technical scheme that its technical problem adopted:
A kind of foundation pit supporting construction comprises diaphragm wall, anchoring pile and beam column, and said beam column one end is located at the stake top of anchoring pile, and the other end is located at the Guan Liang of diaphragm wall.
As the improvement of technique scheme, described anchoring pile is in the diaphragm wall outside.
The beneficial effect of the utility model: the utility model foundation pit supporting construction, adopt diaphragm wall, anchoring pile and beam column fabricated structure, support and anchor pole in avoiding to a great extent being provided with; Be applicable to multiple geological conditions; Can improve the bending rigidity of diaphragm wall, strengthen the soil body lateral pressure ability that opposing increases because of the excavation of foundation pit degree of depth, reduce displacement; Reduce construction costs, can increase cutting depth simultaneously and the possibility of destroying of toppling is reduced.
Description of drawings
Fig. 1 is the sectional drawing of the utility model foundation pit supporting construction;
Fig. 2 is the plan view of the utility model foundation pit supporting construction.
The specific embodiment
See figures.1.and.2, the utility model foundation pit supporting construction comprises diaphragm wall 1, anchoring pile 2 and beam column 3, below be one of form of construction work of this foundation pit supporting construction preferred embodiment:
1, according to site condition, underground diaphragm wall 1 and anchoring pile 2 composite retaining structure structures are carried out calculation Design, around foundation ditch according to construction drawing construction diaphragm wall 1;
2, the construction anchoring pile 2 in precalculated position, diaphragm wall 1 outside;
3, construction beam column 3 between diaphragm wall 1 and anchoring pile 2, an end of beam column is connected with the hat beam 11 of diaphragm wall 1, and the other end is connected with the stake top 22 of anchoring pile 2;
4, diaphragm wall and anchoring pile composite retaining structure structure construction are accomplished, and the earthwork gets into excavation of foundation pit and carries out next step construction working.
What the utility model also will be stressed a bit is that the above-mentioned anchoring pile of mentioning 2 is not limited to prefabricated anchoring pile, also is not limited to existing system anchoring pile.
Certainly; The utility model is not limited to above-mentioned embodiment; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
