Description

Technical Field
The invention relates to the technical field of underground engineering anti-floating, in particular to a pressure relief anti-floating system of an automatic gate valve of a basement.
Background
With more and more underground space buildings in engineering construction, when the underground water level is higher, a large buoyancy force can be generated, and the floating accident of the basement frequently occurs due to improper design, so that great loss is caused to the society.
The anti-floating measures which are commonly adopted at present comprise: the method comprises the steps of structural dead weight (balance weight) anti-floating, an uplift pile arranging method, an uplift anchor rod adding method, a water buoyancy releasing method and a basement peripheral bottom plate extending method, wherein the structural dead weight (balance weight) anti-floating is realized by increasing the weight of a basement bottom plate so as to play a role of anti-floating, and the method is suitable for the conditions that the difference between the structural dead weight and the buoyancy of underground water is not large and the water level of anti-floating and fortification is not high;
the uplift pile method is to utilize the frictional resistance between the pile side and the foundation soil to resist uplift, and the width of a crack needs to be controlled to be less than 0.2mm, however, the uplift pile can only play an uplift role under the condition of an emergent temporary water head, and the uplift pile mainly bears the pressure under other conditions, which is not favorable for controlling the settlement difference between a high-rise main building and a bottom-layer skirt house;
the method for additionally arranging the uplift anchor rod is characterized in that an anti-floating component, namely the anchor rod, is adopted to offset buoyancy generated by underground water to a basement structure, is usually used under the condition that bedrock (or bedrock buried depth is shallow) is arranged under a bottom plate, and a pneumatic down-the-hole hammer drilling machine is adopted to form a hole, so that the construction efficiency is high, the manufacturing cost is low, but the anchor rod has the problem of durability;
the method for releasing water buoyancy is to arrange a hydrostatic pressure release layer below a substrate, so that pressure water below the substrate is collected to a water collecting system (a water filter pipe network) through a water permeable system (a filter layer and a water guide layer) in the release layer, is guided to a water outlet system and then enters a special water tank or a water collecting well to be discharged, and partial water pressure is released. The water pressure releasing method has high requirements on the stability of related drainage equipment, and the long-term operation and maintenance cost in the later period is high;
the method for extending the peripheral bottom plate of the basement is to extend the bottom plate of the basement structure outwards to form a cantilever bottom plate, and the cantilever bottom plate supports the earthing soil to resist the buoyancy of the underground water.
The above measures generally comprehensively determine the design value of the anti-floating water level according to the underground water level condition, the rainfall condition and the like of the current period area, once the anti-floating water level is unreasonably set, the situation that the short-time water level lifting exceeds the expectation under the extreme weather condition cannot be met, and the structure is floated upwards or damaged due to the fact that the anti-floating force of the structure is insufficient to offset the abnormal buoyancy of underground water, so that secondary anti-floating design is often needed, the durability of the anti-floating structure is reduced, and the later maintenance investment is increased.

s3, obtaining the installation number N of the pressure relief pipes (2) according to the water yield data of the pressure relief pipes (2), the pressure relief influence radius of the pressure relief pipes (2) and the area of the anti-floating weak area;
s4, uniformly distributing N pressure relief pipes (2) in a plurality of monitoring wells (1);
s5, installing a water level meter, a pressure transmitter and a flow meter in each monitoring well (1);
s6, connecting each pressure relief pipe (2) with a corresponding gate valve (4);
s7, connecting the water level meter, the pressure transmitter and the flow meter in each monitoring well (1) to a water level monitoring unit (11);
s8, respectively connecting the water level monitoring unit (11) to the water level early warning unit (12) and the gate valve automatic control unit (13);
s9, connecting the gate valve automatic control unit (13) to each gate valve (4).
9. A construction method according to claim 8, characterized in that the water level gauge, the pressure transmitter and the flow meter are installed below the ground level in the monitoring well (1).
10. A construction method according to claim 8, characterized in that the water level gauge, the pressure transmitter and the flow meter are all connected to a water level monitoring unit (11) by means of a 4G router, and the gate valve automatic control unit (13) is connected to each gate valve (4) by means of a 4G router.
