Example 1

Various embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Fig. 1 and 2 depict generally the construction of a waterproof jacket support for an underground utility tunnel. Specifically, fig. 1 is a schematic structural view of a waterproof jacket bracket for an underground pipe gallery according to an embodiment of the present utility model. Fig. 2 is a schematic structural view of a waterproof jacket holder for an underground utility tunnel carrying a waterproof jacket.

As shown in fig. 1 and 2, the present utility model provides a waterproof casing support for an underground pipe gallery, comprising a support frame 1 and two or more spacers 4 disposed within the support frame 1; the partition pieces 4 are respectively arranged in the support frame 1 in a transverse array and a vertical array, and the adjacent partition pieces 4 form a containing space for bearing the waterproof sleeve 3; the embedding direction of the waterproof sleeve 3 is consistent with the extending direction of the underground pipe gallery. The frame system can integrate the densely arranged waterproof embedded sleeves, greatly reduce the embedded time and save the construction cost. The waterproof embedded sleeve can be effectively fixed, and deviation caused by disturbance in subsequent concrete pouring is prevented; the distance between the pipes can be accurately controlled, construction errors are reduced, the leakage possibility of the waterproof embedded sleeve is reduced, and the embedded forming effect is ensured.

In a specific embodiment, the support frame 1 includes at least two rows of accommodating spaces and at least two columns of accommodating spaces. The distance between vertically arranged adjacent spacers 4 is 80-120 mm larger than the outer diameter of the waterproof jacket 3, the optimal distance being 100mm. That is, in order to achieve the effect of effectively fixing the waterproof jacket and saving the installation space, a lattice-shaped accommodation space is formed in the support frame 1. The partition piece adopts a transverse and vertical staggered net structure, and the vertical waterproof sleeve embedding direction is at least provided with two channels, so that the needed embedded sleeve is effectively fixed. The lateral and longitudinal spacing of the spacers should be arranged according to the diameter of the desired buried sleeve and the spacing between tubes.

As an improvement of the embodiment, the underground pipe gallery is long, a single waterproof sleeve support cannot achieve the expected supporting effect, and a plurality of waterproof sleeve supports are required to be arranged in an array in the embedding direction of the waterproof sleeve supports; in order to further increase the stability of the waterproof sleeve support, a water stop screw 2 for connecting adjacent support frames 1 is provided on the support frames 1. The frame system is effectively fixed with the template system by using a water stop screw. Specifically, as the arrangement of the frame affects the volume rate related to the arrangement of the structures in the wall, the thickness of the protective layer of the frame is required to be 50mm larger than that of the reinforcing steel bar protective layer of the wall, so that the frame is positioned in the wall rib and does not collide with the reinforcing steel bars. The screws at the position at the template reinforcing stage are required to be fixed by double nuts, and the compaction of the detail vibration is ensured in the concrete pouring process.

In a specific implementation, the supporting frame 1 is an angle steel member, and the partition 4 is a galvanized round steel member. The frame material is selected from national standard galvanized angle steel 50 x 5, the frames are effectively welded, and phi 10 galvanized round steel welding brackets are adopted in the angle steel frames. Specifically, the supporting frame 1 of the effective fixed set pre-embedded waterproof pre-embedded tool is welded into a box structure by adopting 50 x 5 galvanized angle steel; the phi 10 galvanized round steel is used as a separating piece 4 and welded into a net structure according to the diameter of the embedded waterproof sleeve 3; the round steel net frame formed by the partition pieces is welded on the front side and the back side of the supporting frame 1 and is welded on the inner side of the angle steel; the water stop screw rods 2 are welded on the outer side of the angle steel frame serving as the supporting frame 1, and the water stop screw bolts on each angle steel on the front side and the back side of the angle steel frame are arranged at least twice at intervals of 300 mm; in actual manufacturing, the galvanized round steel is welded with transverse steel bars firstly, and after the pre-embedded waterproof sleeve 3 is placed in the pre-embedded position, the galvanized round steel is welded with vertical steel bars and the sleeve is clamped; after all pre-buried manufacturing is completed, the components of the utility model can be lifted and placed by a lifting appliance; the novel construction is simple and convenient, the construction time is greatly shortened, and the labor cost is reduced.

As a modification of the present embodiment, in order to further increase the service life of the waterproof jacket, a shock-absorbing layer is interposed between the partition 4 and the waterproof jacket 3. Therefore, the waterproof layer can be protected, and the waterproof sleeve can be prevented from rolling in the accommodating space.

In summary, the waterproof sleeve support for the underground pipe gallery provided by the utility model comprises the waterproof sleeve support plates which are arranged continuously and used for the underground pipe gallery; the waterproof sleeve support plate for the underground pipe gallery comprises a concrete slab body 1 and a connecting unit 2 which is arranged on the concrete slab body 1 and is used for connecting hoisting equipment; the connection unit 2 includes a through hole provided on the concrete slab body 1 and a hook provided in the through hole. The frame system can integrate the densely arranged waterproof embedded sleeves, so that the embedded time is greatly reduced, and the construction cost is saved; the waterproof embedded sleeve can be effectively fixed, and deviation caused by disturbance in subsequent concrete pouring is prevented; the space between the pipes can be accurately controlled, the construction error is reduced, the leakage possibility of the waterproof embedded sleeve is reduced, and the embedded forming effect is ensured; and has the characteristics of reasonable structure, low cost and simple construction.
