Description

TECHNICAL FIELD

[0001] The present application relates to a blast-proof transverse ventilation system and construction method suitable for a cave-type data center, and belongs to the technical field of cave-type data center construction. BACKGROUND

[0002] As a specific functional building for storing informatization data, the data center has relatively strict requirements on security protection, and some relatively important data centers require better structural blast-proof performance to ensure normal operation during the war. In order to meet the demand of the data center on the structural blast-proof performance, a cave-type data center placed in the mountain is proposed and gradually promoted in Guizhou area, and substantial progress has been made.

[0003] Since the cave-type data center is buried in the mountain, it needs to set up a ventilation and smoke exhaust system of a certain scale to ensure the ventilation demand during normal operation of the data center and the fire-fighting smoke exhaust demand in case of fire. The Tencent Qixing data center that has been operated and the People's Bank of China Guian data center that is under construction both use a vertical ventilation system of vertical shaft group, which can effectively meet the above ventilation and smoke exhaust demand of the data center, but the vertical shaft vertically penetrating the mountain directly connects the cave-type data center with the space on the top of the mountain, which in a certain sense reserves a structural channel for air attack, and thus weakens the blast-proof effect of the external mountain to a certain extent.

[0004] With the rapid development of high-precision guided weapons, there is a possibility that a bomb will directly reach the inside of the cave-type data center through the vertical shaft channel and then explode from inside to outside. In order to eliminate the above security risks and effectively guarantee the structural blast-proof performance of the cave-type data center, it is of great practical significance to study a blast-proof transverse ventilation system and construction method suitable for the cave-type data center.

During the construction of the support structure of the transverse ventilation main passage 1, reserve passage gaps for connecting vertical shaft 3, inclined downward sunken explosion-proof backup passage 1.6, and left and right side bifurcated air inlet and outlet 1.5.

[0076] 3.4, construction of integrated air supply system 6;

[0077] s4, after the construction of the main transverse exhaust air passage 1 is completed, the construction of the connecting shaft 3 is carried out according to the principle of hole jumping;

[0078] s5, after the construction of the data center chamber 4 and the connecting shaft 3 is completed, the construction of the Y-shaped connecting passage 5 is carried out in two batches in front and back by using left and right side jump trench construction process, and the construction of the obliquely downward sinking type explosion-proof standby passage 1.6 and the left and right side branch type air inlet and outlet 1.5 is carried out simultaneously;

[0079] s6, the installation work of the air door, fan and other equipment of the cave type data center is carried out, and the whole construction project is completed.

[0080] Specifically,

[0081] In step s1, the data center chamber 4 is numbered first, and the left side of the connecting passage 2 is numbered as Z1, Z2…; the right side of the connecting passage 2 is numbered as B1, B2…;

[0082] Then, the connecting shaft 3 is numbered, the connecting shaft 3 is arranged between the two rows of data center chambers 4, and the connecting shaft between Z1 (B1) and Z2 (B2) is numbered as SJ12, and the connecting shafts are numbered as SJ23, SJ34… in turn.

[0083] Then, the Y-shaped connecting passage 5 is numbered, and the connecting passage connected with SJ12 and located on the left side of the connecting passage 2 is numbered as ZLT12, and the connecting passage connected with SJ12 and located on the right side of the connecting passage 2 is numbered as YLT12, and the connecting passages are numbered in turn.

[0084] In step s2, the connecting passage 2 is constructed by using double-head tunneling method, and the lining gaps of the data center chamber 4 and the connecting shaft 3 are reserved during the construction of the supporting structure of the connecting passage 2.

[0085] During the construction of the supporting structure of the connecting passage 2, the reserved lining gaps of the data center chamber 4 and the connecting shaft 3 are constructed by using the method of lining first and digging later, which can be referred to the construction method in the application number 2023101157485 related to a tunnel intersection safety construction method and auxiliary construction device.

[0086] Synchronously, the construction of the outer end of the data center chamber 4 is started by using controlled blasting method in two batches, which can be like Figure 8As shown in the diagram, P1 represents the first construction batch and P2 represents the later construction batch. Specifically, the outer port entry construction of Z1, B2, Z3, B4, Z5... is carried out simultaneously according to the interval construction method. After Z1, B2, Z3, B4... have entered the tunnel for more than 50 meters, the outer port entry construction of B1, Z2, B3, Z4, B5... is carried out simultaneously. After that, all data center caverns 4 are constructed in parallel.

[0087] In step s3, the principle of the pre-set construction procedure for the construction of the inner end of the data center cavern 4 is: to carry out the construction of only two caverns at a time, and the two caverns being constructed at the same time are not in the same or adjacent columns, and are not on the same side, so as to minimize mutual interference between construction. Then, the material transportation route and slag removal route of the two construction caverns are set according to the principle of proximity, that is, the working face near the entrance of the connecting channel 2 selects to transport materials and remove slag from the entrance, and the working face near the exit of the connecting channel 2 selects to transport materials and remove slag from the exit.

[0088] Specifically, after the construction of connecting passage 2 is completed, two construction teams will simultaneously carry out the inner end entry construction of data center cavern 4, as follows: Figure 8 As shown, construction team one will construct in the order of Z1, B2, Z3, B4, Z5… Construction team two will select suitable data center cavern 4 for construction based on the principle that it is not in the same or adjacent column as construction team one, and is not on the same side.

The caverns with 30-meter and 50-meter advances will be arranged alternately to stagger the breakthrough station numbers of data center cavern 4. Specifically, excavation will stop after 50 meters of advance at the inner end of Z1, B2, Z3, B4, Z5… and after 30 meters of advance at the inner end of B1, Z2, B3, Z4, B5…

[0089] Simultaneously, in step s3, the excavation of the outer end of the data center cavern 4 continues in an orderly manner according to the process design in step s2 until the data center cavern 4 is completely connected; and during the construction process, the longitudinal spacing between adjacent tunnel faces should be controlled at all times to be no less than 50 meters, and the data center cavern 4 in the next batch of construction should be connected only after the lining structure of the data center cavern 4 in the previous batch of construction has been poured and formed strength; when constructing the support structure of the data center cavern 4, a lining gap for the Y-shaped connection channel 5 should be reserved;

[0090] In the construction of the support structure of the data center cavern 4, the reserved lining gap of the Y-shaped connecting channel 5 is constructed by lining first and then excavating. For details, please refer to the construction method in the safe construction method and auxiliary construction device of a tunnel intersection involved in application number 2023101157485.

[0091] Synchronously, after the construction of the connecting channel 2 is completed, the ventilation channel 1.2 is constructed in a double-end tunneling manner. The support structure of the ventilation channel 1.2 is constructed with a reserved channel gap for connecting the shaft 3, the obliquely downward sinking explosion-proof standby channel 1.6, and the left and right bifurcated air inlet and outlet 1.5.

[0092] The channel gap of the ventilation channel 1.2 is constructed by the method of lining first and digging later. For details, reference can be made to the construction method in the application number 2023101157485, which relates to a tunnel intersection safety construction method and an auxiliary construction device.

[0093] Synchronously, after the construction of the connecting channel 2 is completed, the integrated air supply system 6 is constructed by a conventional method.

[0094] In step s4, after the construction of the transverse air exhaust main channel 1 is completed, the construction of the connecting shaft 3 is performed according to the principle of hole jumping. Specifically, SJ12, SJ34, … are constructed first, and then SJ23, SJ45, … are constructed. When the construction of the connecting shaft 3 reaches the position connected with the Y-shaped connecting channel 5, the lining gap of the Y-shaped connecting channel 5 is reserved.

[0095] In step s5, the construction of the Y-shaped connecting channel 5 is performed in two batches according to the left and right side hole jumping construction procedure. During the construction process, the construction of the next batch can be performed only after the lining structure of the previous batch channel is poured and forms strength.

[0096] Specifically, after the construction of the data center cavern 4 and the connecting shaft 3 is completed, ZLT12, YLT23, ZLT34, YLT45, … are constructed synchronously first, and then YLT12, ZLT23, YLT34, ZLT45, … are constructed synchronously after the above construction is completed.

[0097] Synchronously, after the construction of the data center cavern 4 and the connecting shaft 3 is completed, the construction of the left and right bifurcated air inlet and outlet 1.5 is performed from the outside of the mountain to the inside of the ventilation channel 1.2, and the construction of the obliquely downward sinking explosion-proof standby channel 1.6 is performed obliquely downward from the inside of the ventilation channel 1.2. The construction time of each intersection of the obliquely downward sinking explosion-proof standby channel 1.6 and the left and right bifurcated air inlet and outlet 1.5 with the ventilation channel 1.2 should be staggered, and the construction of the intersection of the later construction should be performed only after the lining structure of the intersection of the earlier construction is poured and forms strength.

[0098] Specifically, the inclined downward sinking explosion-proof standby passage 1.6 is first constructed in the ventilation passage 1.2, and the left and right bifurcated air inlet and outlet 1.5 are simultaneously constructed from the outside of the mountain; after the intersection section of the inclined downward sinking explosion-proof standby passage 1.6 is lined and poured and has strength, the construction of the intersection of the left (or right) bifurcated air inlet and outlet 1.5 is performed according to the construction progress; after the lining and pouring of the intersection of the left (or right) bifurcated air inlet and outlet 1.5 is completed and has strength, the construction of the intersection of the other side is performed.

[0099] In step s6, the installation of the air door, fan and other equipment of the cave-type data center is performed by a conventional method, and the entire construction project is completed.

[0100] The specific operation process of the intelligent linkage air door is as follows:

[0101] The initial state of the multi-air-door linkage horizontal ventilation system: the upper air door 3.1 and the lower air door 3.2 of the shaft, the outer air door 4.1 and the inner air door 4.2 of the cave, the left connecting port air door 5.1 and the right connecting port air door 5.2 are all in the closed state; except that the jet fan 7.2 arranged at the arch of the connecting passage 2 is regularly opened as needed, the jet fan 7.1 arranged at the arch of the horizontal exhaust main passage and the axial flow fan 7.3 arranged at the upper end of the connecting shaft 3 are both in the closed state; at this time, the air flow of each data center cave 4 is in a mutually independent state.

[0102] When the normal operation state needs to be performed for air replacement construction of a certain data center cave 4 (taking the Z3 data center cave as an example): starting from the initial state of the multi-air-door linkage horizontal ventilation system, the right connecting port air door 5.2 of the Y-shaped connecting passage ZLT23 is opened, and then the upper air door 3.1 of the connecting shaft SJ23 is opened, and then the axial flow fan 7.3 in the connecting shaft SJ23 and the jet fan 7.1 at the arch of the horizontal exhaust main passage 1 are opened for air extraction construction, and the integrated air supply system 6 is switched to the fresh air supply subsystem 6.1, and then new air is sent to the Z3 data center cave 4 through the buried air supply pipeline 6.4; the replacement of the air inside the Z3 data center cave 4 is completed by the side extraction and side supply. The air replacement construction of other data center caves 4 can be performed by reference; after the air replacement construction is completed, the multi-air-door linkage horizontal ventilation system is switched to the initial state.

[0103] In the case of fire, the smoke exhaust construction of a certain data center chamber 4 is carried out (take Z3 data center chamber as an example): starting from the initial state of the multi-vent linkage horizontal ventilation system, open the right side connecting port vent 5.2 of the Y-shaped connecting channel ZLT23 and the left side connecting port vent 5.1 of the Y-shaped connecting channel ZLT34, and then open the shaft upwind vent 3.1 of the connecting shaft SJ23 and the connecting shaft SJ34, and then open the axial flow fan 7.3 in the connecting shaft SJ23 and the connecting shaft SJ34 and the jet fan 7.1 in the arch part of the horizontal exhaust main channel 1 for exhaust construction, and switch the integrated air supply system 6 to the fire-retardant gas supply subsystem 6.2, and then send the fire-retardant gas to the Z3 data center chamber 4 through the embedded gas pipeline 6.4; through the form of exhaust and supply, the gas in the Z3 data center chamber 4 is quickly replaced, and the purpose of rapid smoke exhaust and flooding fire extinguishing is achieved. The smoke exhaust construction of other data center chambers 4 can be carried out by reference; after the air change construction is completed, the multi-vent linkage horizontal ventilation system is switched to the initial state.

[0104] When the connecting channel 2 needs to be segmented for smoke exhaust (take the example of opening the connecting shaft SJ23 for segmented ventilation): starting from the initial state of the multi-vent linkage horizontal ventilation system, open the shaft upwind vent 3.1 and the shaft downwind vent 3.2 of the connecting shaft SJ23, and then open the axial flow fan 7.3 in the connecting shaft SJ23 and the jet fan 7.1 in the arch part of the horizontal exhaust main channel 1 for segmented exhaust construction. After the exhaust construction is completed, the multi-vent linkage horizontal ventilation system is switched to the initial state.

[0105] The above is only a preferred embodiment of the present application, and is not a limitation on the present application. Any simple modification, equivalent change and modification of the above embodiment without departing from the technical solution content of the present application, according to the technical essence of the present application, still belongs to the scope of the technical solution of the present application.
