Abstract
The invention discloses an anti-floating pressure-relief drainage system comprising a bedrock layer, a base board and a ground water permeable layer. The ground water permeable layer is located above the bedrock layer. The system further comprises a pressure-relief well communicated with the ground water permeable layer and a draining device used for draining underground water in the wall and relieving the pressure, and the pressure-relief well is located on the outer side of the base board. Since the pressure-relief well is mounted outside the base board, the situation of floating produced by a system body can be acquired by observing the level changes in the pressure-relief well; when the level in the pressure-relief well is higher than that of floating that the base board is capable of bearing, the underground water in the pressure-relief well can be drained timely through the draining device, the situations that the water difference between the building underground structure bottom and the side wall is large and an anti-floating device is in failure in the life cycle are avoided effectively, the anti-floating stability of the underground structure is retained, the situation of underground structure deformation, cracking and water penetrating caused by water pressure difference are avoided effectively, the normal service life of the underground structure is guaranteed.

Detailed description of the invention
Core of the present invention is to provide a kind of draining pressure release anti-floating system, and this draining pressure release anti-floating system can effectively avoid anti-floating system to lose efficacy in its life cycle, thereby affects the situation in the application life of underground structure.
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with drawings and embodiments, the present invention is described in further detail.
Please refer to Fig. 1 to Fig. 2, in a kind of detailed description of the invention, draining pressure release anti-floating system provided by the invention comprises horizon d 4, foundation slab 6, ground pervious layer 5, fill stratum 3 outside basement, relief well 1 and exhaust device, outside basement, fill stratum 3 and ground pervious layer 5 are positioned at horizon d 4 tops side by side, ground pervious layer 5 is between horizon d 4 and foundation slab 6, relief well 1 communicates with ground pervious layer 5, concrete, relief well 1 can be positioned at fill stratum 3 outside basement, exhaust device is for pump drainage, the interior underground water of relief well 1, relief well 1 is positioned at foundation slab outside, concrete, relief well 1 can be cuboid relief well, for convenient construction relief well, the preferred relief well 1 of the present invention is cylindrical relief well.Ground pervious layer 5 can be made up of rubble, for fear of the situation of attenuation in the long-time use procedure of ground pervious layer 5, the preferred ground pervious layer 5 of the present invention is gravel layer, because gravel layer quality is hard, smooth in appearance, can more effectively avoid the situation of being out of shape because of the impact of underground water.
Can judge draining pressure release anti-floating system internal buoyancy situation by the height of water level of observing in relief well 1, when the water level in relief well 1 is during higher than predetermined buoyancy water level, when predetermined buoyancy water level is the buoyancy that draining pressure release anti-floating system bears in safe range, the water level at place, needs by evacuation system, the underground water in relief well 1 to be extracted out in time.
Known by foregoing description, in draining pressure release anti-floating system provided by the invention, because foundation slab 6 outsides are provided with relief well 1, can learn by observing the interior SEA LEVEL VARIATION situation of relief well 1 stressing conditions of draining pressure release anti-floating system.The ground pervious layer 5 that the present invention utilizes the site topography gradient and foundation slab 6 bottoms to arrange forms water passage, thereby has reduced the head difference between foundation slab 6 and outer wall of underground structure 3; By the relief well 1 communicating with ground pervious layer in foundation slab 6 periphery settings, effectively avoid the larger situation of building underground structure both sides head difference, and then the stability of maintenance underground structure, effectively avoid the situation such as underground structure cracking, infiltration causing because of differential water pressures, guaranteed the normal service life of underground structure.On the other hand, the present invention carries out pump drainage to underground water as required by relief well 1 is set, and can save the cost that anti-floating system is set, and the situation of avoiding anti-floating system to lose efficacy in its life cycle has ensured the normal service life of underground structure.Avoid uncontrollable factor in traditional anti-floating system mechanism, prevention and control flexibly, easy construction, cost is lower.
Further, this draining pressure release anti-floating system also comprises the water level monitoring system for monitoring relief well 1 interior groundwater level.In the time that water level monitoring system measures the interior water level of relief well 1 higher than the predetermined buoyancy water level of water level, water level monitoring system is reported to the police, need in time the underground water in relief well 1 to be extracted out by exhaust device, in the time that relief well 1 water level returns to predetermined buoyancy water level, stop pump drainage work.By monitoring system is set, the monitoring efficiency of can effectively flooding, avoid personal monitoring not in time and discontinuity, can monitor better the situation of change of groundwater table, be more conducive to carry out in time draining pressure release work.
In order to carry out timely and effectively the pump drainage work of underground water, this draining pressure release anti-floating system comprises multiple relief wells 1,1 of multiple relief well are all positioned at foundation slab 6 outsides, by being set, can in time the underground water higher than predetermined floating water bit line be extracted out by multiple relief wells 1, effectively avoid the larger situation of building underground structure both sides head difference, and then the stability of maintenance underground structure, effectively avoid the situation such as underground structure cracking, infiltration causing because of differential water pressures, guaranteed the normal service life of underground structure.
For even pump drainage is higher than the underground water of preset water level, distance in this draining pressure release anti-floating system between adjacent two relief wells 1 equates, effectively avoid the underground structure unbalance stress causing because the pump drainage water yield is inhomogeneous, the impact of avoiding secondary stress to cause underground structure.
The present invention is preferred, and the bottom of relief well 1 is positioned at the upper surface of horizon d 4, is more conducive to the ponding effect of easing stress of relief well.
On the basis of above-mentioned each scheme, the upper surface of main structure body top board 2 is descended on the top of relief well 1 above Ground, because the upper surface of main structure body top board 2 is descended on the top of relief well 1 above Ground, has effectively avoided the impact of surface water on relief well periphery soil layer.
