Abstract
The utility model discloses a kind of building foundation pit prestressed anchor fixing structure, include diaphragm wall, be anchored at the presstressed reinforcing steel that outside foundation ditch, in soil layer and one end is fixedly connected with diaphragm wall, described diaphragm wall wall is installed with pedestal, pedestal is provided with bearing plate, bearing plate is provided with the ground tackle be connected with presstressed reinforcing steel end; The described presstressed reinforcing steel other end is connected with anchoring body, described anchoring body comprises the anchoring cone solid, cylindrical anchors solid and the columniform end anchor solid that connect successively, described end anchorage body is positioned at presstressed reinforcing steel one end away from diaphragm wall, described anchoring cone solid opposed end anchoring body is near diaphragm wall, and the bottom surface of anchoring cone solid is towards diaphragm wall.This anchor structure is by the frictional force of cylindrical anchors solid and soil layer, and anchoring cone solid, end anchor solid match with the pressure between soil layer, thus form pulling force between diaphragm wall and soil layer, make diaphragm wall obtain stable supporting.
Description
Technical field
The utility model belongs to building foundation pit supporting field, is specifically related to a kind of anchor structure of building foundation pit.
Background technology
Soil bolt is a kind of tension member imbedded in soil layer, one end of anchor pole is connected with the diaphragm wall of foundation ditch, and the other end is anchored in soil layer, usually to its Shi Hanzhang, to bear the pulling force produced by soil pressure, water pressure, in order to safeguard the stability of diaphragm wall.One end that usual anchor pole is arranged in soil layer is connected with the anchoring body of columniform concrete structure, and for the soil layer that such as clay one class is weaker, common anchor pole is difficult to meet the demands.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of prestressed anchor fixing structure being suitable for carrying out the diaphragm wall that foundation ditch periphery is soft soil layer anchoring support.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of building foundation pit prestressed anchor fixing structure, include diaphragm wall, be anchored at the presstressed reinforcing steel that outside foundation ditch, in soil layer and one end is fixedly connected with diaphragm wall, described diaphragm wall wall is installed with pedestal, pedestal is provided with bearing plate, bearing plate is provided with the ground tackle be connected with presstressed reinforcing steel end; The other end that described presstressed reinforcing steel is positioned at soil layer is connected with anchoring body, described anchoring body comprises the anchoring cone solid, cylindrical anchors solid and the columniform end anchor solid that connect successively, described end anchorage body is positioned at presstressed reinforcing steel one end away from diaphragm wall, described anchoring cone solid opposed end anchoring body is near diaphragm wall, and the bottom surface of anchoring cone solid is towards diaphragm wall.
Preferably: described presstressed reinforcing steel periphery is positioned at soil layer and the part differing from anchoring body forms secondary builds portion.
Preferably: the length of described cylindrical anchors solid is more than 2 times or 2 times of end anchorage body length; The diameter of described anchoring cone solid bottom surface is less than the diameter of end anchor solid; Form the angle of 65-75 ° between described presstressed reinforcing steel and diaphragm wall, described diaphragm wall to soil layer lopsidedness outside foundation ditch, and forms the angle of 5-10 degree between diaphragm wall and vertical direction.
Compared with prior art, the beneficial effects of the utility model are: this anchor structure passes through the frictional force of cylindrical anchors solid and soil layer, and anchoring cone solid, end anchor solid match with the pressure between soil layer, thus pulling force is formed between diaphragm wall and soil layer, make diaphragm wall obtain stable supporting; The part of described soil layer between anchoring cone solid and end anchor solid, owing to being subject to the pressure of end anchor solid, makes it density higher, and the frictional force between original work anchoring body strengthens greatly.The described secondary portion that builds uses concreting to form after anchor construction completes, and guarantees that the presstressed reinforcing steel of cable wire or reinforcing bar material is corroded.Described diaphragm wall is to soil layer lopsidedness outside foundation ditch, and coordinate the presstressed reinforcing steel of the angle forming with it 65-75 °, compare vertical diaphragm wall and the presstressed reinforcing steel of horizontal arrangement, supporting intensity improves more than 20%.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to Fig. 1, a kind of building foundation pit prestressed anchor fixing structure described in the present embodiment, include diaphragm wall 4, be anchored at the presstressed reinforcing steel 5 that outside foundation ditch, in soil layer and one end is fixedly connected with diaphragm wall, described diaphragm wall wall is installed with pedestal 3, pedestal is provided with bearing plate 2, bearing plate is provided with the ground tackle 1 be connected with presstressed reinforcing steel end; The other end that described presstressed reinforcing steel is positioned at soil layer is connected with anchoring body, described anchoring body comprises the anchoring cone solid 7, cylindrical anchors solid 8 and the columniform end anchor solid 9 that connect successively, described end anchorage body is positioned at presstressed reinforcing steel one end away from diaphragm wall, described anchoring cone solid opposed end anchoring body is near diaphragm wall, and the bottom surface of anchoring cone solid is towards diaphragm wall.
Described presstressed reinforcing steel periphery is positioned at soil layer and the part differing from anchoring body forms secondary builds portion 6.
The length of described cylindrical anchors solid is more than 2 times or 2 times of end anchorage body length; The diameter of described anchoring cone solid bottom surface is less than the diameter of end anchor solid; Form the angle of 70 ° between described presstressed reinforcing steel and diaphragm wall, described diaphragm wall to soil layer lopsidedness outside foundation ditch, and forms the angle of 8 degree between diaphragm wall and vertical direction.
This anchor structure is by the frictional force of cylindrical anchors solid and soil layer, and anchoring cone solid, end anchor solid match with the pressure between soil layer, thus form pulling force between diaphragm wall and soil layer, make diaphragm wall obtain stable supporting; The part of described soil layer between anchoring cone solid and end anchor solid, owing to being subject to the pressure of end anchor solid, makes it density higher, and the frictional force between original work anchoring body strengthens greatly.The described secondary portion that builds uses concreting to form after anchor construction completes, and guarantees that the presstressed reinforcing steel of cable wire or reinforcing bar material is corroded.Described diaphragm wall is to soil layer lopsidedness outside foundation ditch, and coordinate the presstressed reinforcing steel of the angle forming with it 70 °, compare vertical diaphragm wall and the presstressed reinforcing steel of horizontal arrangement, supporting intensity improves more than 20%.
