The open end of the fixing member 36 is fixed with a hinge seat 35, the end of the connecting pipe 34 is rotatably connected in the hinge seat 35, and the rotating connection between the connecting pipe 34 and the fixing member 36 is completed through the hinge seat 35.

In embodiment 3, as shown in fig. 4, unlike embodiment 1, eight connecting mechanisms 3 are provided, and specifically, the connecting mechanisms 3 are fixed on the outer side of the circular radiant tube 2 in a shape like a Chinese character 'mi'.
s1, selecting four linear radiant tubes 1, fixing the four linear radiant tubes 1 to form a square frame by using a right-angle connector 11, wherein one end angle of the square frame is arranged at a vertical well of the radiant well, and an area covered by the square frame corresponds to a space range area of the radiant well;
s2, selecting a circular radiant tube 2 with a proper radius, wherein the diameter of the circular radiant tube 2 is 10m, 20m, 30m, 40m or 50m, selecting four connecting mechanisms 3 to fix the circular radiant tube 2 in a square frame, specifically, fixing the four connecting mechanisms 3 on the outer side of the circular radiant tube 2 at equal intervals by using arc-shaped tubes 31, rotating the relative positions of the circular radiant tube 2 and the square frame to enable a sleeve 32 and a sleeve 33 of each connecting mechanism 3 to be arranged on a straight line where a diagonal of the square frame is located, and then adjusting the relative length of the sleeve 33 of the sleeve 32 to sequentially fix two fixing pieces 36 on the same connecting tube 34 on two adjacent linear radiant tubes 1 by adjusting the relative length of the sleeve 33 of the sleeve 32
The circle center of the circular radiant tube 2 corresponds to the center of the square frame, the circular radiant tube 2, the square frame and the connecting mechanism 3 form a layout base frame, and then the curtain is laid on the base frame, so that the layout can be completed.
Compared with a curtain and a non-curtain, the anti-floating decompression result is implemented under the arrangement scheme that the diameter of the circular radiant tube 2 is 10m, 20m, 30m, 40m or 50m, and is as follows:
by combining the comparison graph of the precipitation pressure reduction results of the circular radiant tube schemes with different radiuses at the bottom of the space under the non-curtain condition shown in the attached drawing 5 and the comparison graph of the precipitation pressure reduction results of the circular radiant tube schemes with different radiuses at the bottom of the space under the curtain condition shown in the attached drawing 6, the area influenced by a certain pressure water head value is firstly reduced and then increased along with the increase of the radius of the circular radiant tube 2. When the curtain is not used, the arrangement schemes of the circular radiant tubes 2 with different radiuses can be reduced to within the safe pressure intensity under the condition that the water pumping depth of the vertical shaft is reduced greatly and the water pumping depth of the vertical shaft is reduced by 8m and 9m, so that the pressure reduction requirement is met.
When the shaft is lowered to 7m, it is clear that the decompression target is achieved only when the radius of the circular radiant tube is 30 m. Meanwhile, by combining the change conditions of the influence areas of other pressure water head values under the condition of the depth reduction of different vertical shafts in the diagram, the area of the pressure water head at the bottom of the space, which is larger than a certain value, is the smallest when the radius of the circular radiant tube 2 is 30m, the pressure reduction effect is the best, and the pressure maximum value is the lowest.
When the curtain acts, the change rule still exists, but due to the waterproof pressure control effect of the curtain, under the condition that the three different vertical shafts are used for reducing the depth, the pressure reduction target can be achieved when the radius of the circular radiant tube is smaller, and under the condition that the pressure reduction requirement is met, the radius of the distributed circular radiant tube is 20m, the pressure reduction value is the largest, and the pressure reduction efficiency is the highest. Compared with the scheme without the curtain function, the radius of the circular radiant tube of the optimal decompression scheme is reduced, the length of the required radiant tube is reduced, and the pressurizing effect is better when the water insulation of the curtain and the drainage of the radiant tube act together.
The depth of the vertical shaft is reduced by 8m in combination with the graph of fig. 7, the radius of the circular radiant tube is 20m, the distribution pattern of the pressure head at the bottom of the precipitation space can be known, the arrangement position and the arrangement form of the radiant tube can be visually seen through the distribution situation of the pressure head, the pressure head value of the position where the radiant tube is arranged is small, the pressure head value of the area which is farther away from the radiant tube is gradually increased, the position which is closer to the vertical shaft is at the position of the southwest corner of the space, the response of the water level change is obvious, and therefore the local minimum pressure head value appears in the area.
Compared with the same decompression scheme under the condition of having or not having the curtain, when having the curtain effect, space bottom pressure head value is whole 1.5m less than when having not having the curtain, and the pressure head decline of radiant tube position is bigger, shows that the laying mode anti-floating decompression efficiency in this embodiment is higher under the curtain effect.
From the distribution condition of the pressure head, the phenomenon that the area larger than a certain pressure head value is firstly reduced and then increased and the pressure reduction effect is firstly obvious and then weakened along with the increase of the radius of the circular radiant tube can be explained. Because the circular radiant tubes are added in the inverted filter layer under the influence of the radiant tube precipitation radius, the circular radiant tubes and the inverted filter layer have the superposition of precipitation influence radii, when the radius is small, the influence radius of the middle circular radiant tube is also small, the influence radius of the outer radiant tube is limited, partial areas at the bottom of the space have relatively delayed response for water level change, and the pressure reduction effect is not good. Along with the increase of the radius of the middle circular radiant tube, the influence radiuses of the inner and outer circles of radiant tubes are mutually overlapped, the water level change response of the bottom of the space is rapid, the depth change value is also overlapped to a certain extent, and the effect of reducing the pressure is the best at the moment. When the radius of the inner circular radiant tube continues to increase, the influence range of the circular radiant tube is greatly overlapped with the influence range of the radiant tube in the outer green turning layer, the influence radius of the radiant tube cannot reach the inner area of the radiant tube, and the voltage reduction effect becomes worse.
Combining the influence of the precipitation pressure reduction on the seepage field by the circular radiation tube scheme with different radiuses at the bottom of the space under the condition of the curtain in the graph 8, the influence of the precipitation pressure reduction on the seepage field by the circular radiation tube scheme with different radiuses at the bottom of the space under the condition of the curtain in the graph 9, and the influence of the precipitation pressure reduction on the seepage field by the circular radiation tube scheme with the radius of 20m in the graph 10, the depth reduction distribution graph of the local water level of the precipitation with the radius of 20m in the graph is known, when the curtain is not used, the radius change of the circular radiation tube and the increase of the length of the radiation tube at the bottom of the space basically cannot influence the depth reduction distribution graph of the seepage field, because the region with the larger disturbance of the precipitation pressure reduction on the seepage field is mainly concentrated at the position where the radiation tube is arranged, the influence radius of the radiation tube is smaller, the water level disturbance caused by the radius increase of the circular radiation tube only relates to the bottom region of the space, and the farther position can also change due to the influence of the precipitation of the water level by the radiation well, but is substantially unresponsive to local changes in the radiant tube.
Under the condition of a curtain, the variation trend of the depth reduction influence area along with the radius of the circular radiant tube is basically consistent with that of a non-curtain, and the difference is that when the radius is 20m, the area of the underground water level variation larger than a certain value is obviously reduced, which shows that in a precipitation pressure reduction scheme with the radius of 20m, the variation value of the whole water level in the simulation area is not large, and meanwhile, the safe pressure-resistant water level can be met. Under the dual action stack of curtain and radiant tube, the anti superficial decompression effect of this scheme is the best, and economic investment is less to the influence in seepage field, convenient to popularize and use.
Embodiment 5, different from embodiment 4, when four connecting mechanisms 3 are selected, the relative positions of the circular radiant tube 2 and the square frame are rotated, so that the sleeve 32 and the sleeve 33 of the connecting mechanism 3 are arranged parallel or perpendicular to the linear radiant tube 1, and then the relative length of the sleeve 33 of the sleeve 32 is adjusted to fix the two fixing pieces 36 on the connecting tube 34 at the middle section of the adjacent linear radiant tube 1, and the connecting tube 34 is parallel to the adjacent linear radiant tube 1, thereby increasing the flexible and selective arrangement.
In embodiment 6, when different from embodiment 4, eight connection mechanisms 3 are selected, the eight connection mechanisms 3 are fixed on the outer side of the circular radiation tube 2 at equal intervals by using the arc-shaped tubes 31, then the relative positions of the circular radiation tube 2 and the square frame are rotated, so that the sleeves 32 and the sleeves 33 are arranged in a grid of the square frame in a shape like a Chinese character mi, and then the relative lengths of the sleeves 33 of the sleeves 32 are respectively adjusted, so that the fixing members 36 are respectively fixed on the linear radiation tubes 1, thereby increasing the arrangement stability.
