Description

Method for building closed space

Technical Field

Background

Human march into space requires a closed space. To travel in space for long periods of time, it is necessary to make the enclosure large enough, even to achieve a self-sufficient ecosystem. Therefore, a closed macro space needs to be built, and once gas leakage occurs in the space, the gas leakage can be found in time and maintained in time.

installing an upper-stage elevator shaft pillar member 16 by means of an elevator, aligning the upper-stage elevator shaft pillar member 16 with a connecting rod of a pillar reinforcement, placing the upper-stage pillar member, connecting and fixing the upper-stage elevator shaft pillar member 16 with an elevator shaft pillar member 16 below by using a pillar connecting piece 15, and then welding the adjacent part of the electric wire;

after the four elevator shaft strut members 16 at the same level are connected and fixed, strut reinforcements are inserted for reinforcement connection as described above;

next, installing a power-saving elevator shaft strut member 16, lifting the elevator, using the safety column of the elevator and the cross bar for assistance, continuously installing an elevator shaft strut member 16 which is a third section strut member of one elevator shaft strut, the installation method is the same as the previous method, welding the adjacent positions of the electric wires after installation, continuously lifting the elevator to a proper position, installing elevator shaft strut beam connecting members, connecting the top ends of four elevator shaft struts of one elevator shaft layer by using the elevator shaft strut beam connecting members and the cross beams, and then welding the adjacent positions of the electric wires, as shown in fig. 5 and 6; at the moment, the pillar reinforcement is detached respectively, the arm connecting rod is detached firstly, then the arm of the reinforcement is screwed off, then the connecting rod of the pillar reinforcement is taken out from the center of the elevator shaft pillar by using the connecting rod taking-out rod, and after the pillar reinforcement is detached, the pillar connecting piece 15 is installed on one side of the opposite surfaces of the two elevator shaft pillars to reinforce the elevator shaft pillars; attention is paid to the connection between the electric wires, and the two ends of each electric wire saving support with the electric wires are provided with protective devices which are taken down when being connected so as to prevent electric shock.

And after the four-corner elevator shaft on the same floor is built, the elevator shaft on the next floor is built. The specific construction mode is the same as that of one elevator shaft (only one elevator is placed in one elevator shaft), and the third elevator shaft is repeatedly built. In order to facilitate the capping of the third floor, the components of an elevator shaft with one floor height are prepared, the elevator shaft with one floor is added in an elevator shaft at one corner, and the column beam near the corner elevator shaft at the third floor is conveniently built. After the column beam near the corner elevator shaft is built, the fourth layer of elevator shaft components at the corner are removed, the fourth layer of elevator shaft is installed at the other corner, and the same operation is carried out by repeating the four corners. After the whole top column beam is built, the elevator shaft of the fourth floor is disassembled.

S5, building a layer of space pillars and beams:

the beam and the support column of one floor can be installed by utilizing the safety columns of the elevator shaft, the elevator and the elevator to build the long-arm crane.

S6, laying a second layer of floor tiles:

paving floor tiles of a second layer and above layers from the position near the elevator shaft, wherein the specific method is the same layer;

s7, building an outer wall of the first floor, arranging door openings on the partition walls of each room inside, and erecting a ladder step.

Building a wallboard 9 for mounting the outer wall, a leaking stoppage strip 10 and a connecting piece 11, mounting one end of the wallboard on the outer sides of the upper and lower cross beams when mounting the wallboard, and then fixing the connecting piece at the other end of the wallboard by using screws. Finally, the middle wall plate is installed, see fig. 7, after the installation of the outer wall on one side of the closed space is finished, the gap of the wall plate is plugged by the plugging strip, and the sealing performance, namely the closing performance of the space is ensured. The two-layer or three-layer external wall and partition wall of each layer are treated by the method

The door opening is arranged and the ladder step is erected according to the usual way, and the sealing performance of the door opening is only noticed, so that no air leakage place exists.

S8, building a column beam of a second layer;

s10, laying a third layer of floor tiles;

s11, building a third-layer column beam;

s13, laying a ceiling of the closed space;

the ceiling can be used for mounting floor tiles and can also be capped by using wall plates.

And S14, installing air extractors in the staircase front chamber 3, the first elevator room front chamber 401, the air storage chamber 6 and the second elevator room front chamber 402, conveniently extracting air and releasing air when entering and exiting the closed space, and avoiding air escaping from the closed space.

S15, mounting wind direction wallpaper 12 on the inner wall of the closed space, as shown in figure 8, when air leakage occurs, the wind direction fibers and the leakage stoppage rubber balls 13 of the wind direction wallpaper swing along the air flow direction, so that the air leakage position can be conveniently and quickly observed, and accurate remedial measures can be carried out.

S16, an air pressure detector is installed, the air pressure in the closed space can be monitored in real time, and when the air pressure is too high, too low or fluctuates greatly, an alarm is given out to remind the user to detect.

And S17, filling gas into the closed space through the door opening to enable the gas pressure to reach the specified requirement, and recording the pressure value at the moment.

And S18, after the air inflation is finished, if the air pressure is not reduced within the specified time, the function of the closed space is normal. If the air pressure is reduced, air leakage is shown, the wind direction wallpaper is observed, the air leakage position is conveniently found out, and the air leakage position is maintained.

And S19, entering and exiting the closed space. When entering, firstly, air in the transition space is pumped into the air storage chamber, the entrance door of the closed space is opened, the transition space enters the transition space, the entrance door is closed, air in the storage chamber is released, when the air pressure in the two chambers is balanced, the door from the transition space to the storage chamber is opened to enter the storage chamber, and then the door from the storage chamber to the inner space is opened to enter the inner space. When the air flows from the inner space to the outside of the closed space, the air enters the transition space and is pumped into the storage chamber. And opening the access door of the transition space to the outside of the closed space. Since the enclosed space is disposed in outer space, there is a place where there is no air. If the simulated space is created on the ground, the air pressure inside the enclosed space will be much higher than the air pressure outside. For example, in the case of high altitude at an altitude of 6000 m, atmospheric pressure is 60% of the standard atmospheric pressure, and in this state, human movement is very difficult.

There is no air on the moon, and the air on the spark is very thin.

Maintenance of the enclosed space:

discovery of air leakage. When the barometer shows that the pressure drops, the state of the wind direction wallpaper needs to be checked. The wind direction fiber and the plugging rubber ball 13 are different from the air leakage position. The wall plate or the floor plate can be replaced. When the wall plate is replaced, air in the space where the wall plate is located needs to be extracted, and then the wall plate is replaced.

The doors of the elevator car and staircase front rooms must be provided as normally closed doors. When the outer wall of the elevator shaft leaks to cause the front door of the elevator shaft to be not opened, the front door of the elevator shaft can be accessed from the staircase on the other floor. The air of the staircase front room is pumped out to the staircase and then the door of the elevator car front room is opened. And searching the air leakage position for repairing. See in particular the above-mentioned outer wall repair. Replacement is also easy if damage occurs to the columns or beams of the elevator shaft.

Updating the closed space:

the material of the enclosed space ages over time and must be replaced with a new component. The space near the outer wall is first replaced with the columns and beams of the outer wall and then the wall panels of the outer wall.

When the column beam is replaced, the auxiliary strut is needed to support the column beam around the replaced position, the air in the local space where the column beam is located is pumped out, and then the column beam is replaced. When the wall plate is replaced, the wall plate is firstly detached, then the beam is detached, the beam is replaced, and finally the wall plate is installed. The wall-changing plate is relatively simple and will not be described here. In the case of column beam replacement, when it relates to the space between the upper and lower floors, the relevant beams of the relevant four rooms of the elevator shaft column joint are supported by auxiliary columns, the air in the relevant rooms is evacuated, then the wall plates and cross members connected to the elevator shaft column joint are removed, and the elevator shaft column joint is removed for replacement.

For the ground enclosed space, the replacement should be carried out layer by layer from bottom to top.

And (3) building a closed space in space.

The space has no gravity and no air. Once moving, the objects are not easy to stop, so that collision and separation between the objects must be highly regarded. An object will not return to its original position if no action is taken after it has left. All components must be connected during construction to prevent the components from being lost by being scattered into space.

Firstly, determining the operation orbit of the space enclosed space.

In a second step, a spatial bin is sent to the track. The space bin provides functions of energy, communication, storage and the like. Two spatial bins are sent if necessary. Two space bins are used as the starting condition for building the space city. The space cabin in charge of butt joint with ground goods transportation provides energy and communication for building a space city, and meanwhile, the space cabin is a passage for entering a working cabin, namely a working cabin, of a working and material storage cabin. The outer end of the working chamber has an outlet and the base of a pre-built elevator shaft, see fig. 9 and 10.

And thirdly, sending the construction robot and the components required by the closed space to the space bin. The supply of materials and equipment is then scheduled according to the construction schedule.

And fourthly, building two elevator shafts, as shown in figure 11.

And fifthly, constructing a zero space. See fig. 12 and 13.

The eight grids except the middle of the bottom surface of the first layer are all paved with floor tiles, the outer walls of the four sides of the first layer are closed, the outer walls of the two sides of the four corners of the second layer are closed, the floor tiles are paved when the tops of the four corner spaces are closed, and the tops of the two layers are shown in figure 14.

The number zero space is used for placing more assemblies and more devices, so that more cargoes can be conveniently conveyed, and the project building progress can be conveniently accelerated.

Sixth, the hoistway is constructed in five directions, see fig. 15 and 16.

And seventhly, constructing the bottom of the space city, wherein the bottom is divided into two layers or three layers, and the space city is the bottom of the space city enclosure structure, as shown in figure 17.

And eighthly, building a space city four-side enclosure structure from the bottom upwards, wherein each side is divided into two to three layers. See fig. 18, the cross section of the middle of the space city, with the center being the elevator shaft, like four-way extensions and elevator shafts, both enhances the robustness of the overall structure and provides the material requirements in the construction of the structure. Figure 19 is a side of a space city.

And ninthly, capping to finish the construction of the external structure of the space city.

Tenth, wind direction wallpaper is pasted on the inner side of the outer wall of the maintenance structure.

And step ten, detecting and maintaining air leakage.

The whole construction process is similar to the construction of a closed space on the ground. It should be noted that all objects must have connections and that a solution to unwrap is required when entanglement occurs between the connections.

If the construction of a space city is to be accelerated, multiple ports may be connected to accelerate the supply of materials, equipment, etc. See fig. 20-22.

The overall structure updating method of the space city is the same as the updating method of the ground closed space, the structure updating is easier than the ground due to the weak influence of the space gravity, and attention is needed to be paid to preventing air leakage and component escape.
