TECHNICAL FIELD
[0001] The utility model relates to a splicing auxiliary device of socket type prefabricated multi-arc comprehensive pipe gallery. BACKGROUND
[0002] With the development of city and the increase of pipeline and the limitation of ground space, the underground space has to be developed, and the underground comprehensive pipe gallery becomes the main structure for placing various pipelines. The comprehensive pipe gallery mostly shuttles in the area where personnel and buildings are concentrated, and basically adopts the socket type prefabricated multi-arc comprehensive pipe gallery. The socket type prefabricated multi-arc comprehensive pipe gallery has the characteristics of fast assembly construction. The connection and installation of the socket type prefabricated multi-arc comprehensive pipe gallery is the key point for controlling the quality and progress of the comprehensive pipe gallery. The traditional assembly construction method is to use the crane and manual cooperation to insert and splice the socket of the single pipe gallery, which often causes the damage of the concrete at the socket end of the pipe gallery, resulting in the leakage of the splicing part of the pipe gallery and the consumption of the assembly time. If the supporting counter-pulling structure is used, the installation time is long and the supporting structure is easy to fall off. SUMMARY
[0003] The utility model aims at overcoming the defects of prior art and providing a splicing auxiliary device of socket type prefabricated multi-arc comprehensive pipe gallery, which is convenient to install and can guarantee the installation quality and speed of the pipe gallery.

[0007] Two counter-pulling steel wire ropes are wound around the inner end of a pair of bolts on the pipe gallery section to be spliced and the inner end of a corresponding pair of bolts on the spliced pipe gallery section;
[0008] Two hand-operated hoists are connected between the ends of the two counter-pulling steel wire ropes.
[0009] The splicing auxiliary device of the socket type prefabricated multi-arc comprehensive pipe gallery, wherein the steel sleeve is welded with the steel bar on the side wall of the pipe gallery section.
[0010] The splicing auxiliary device of the socket type prefabricated multi-arc comprehensive pipe gallery, wherein the inner end of the bolt is sequentially provided with a anti-dropping ring and a steel wire rope groove.
[0011] The splicing auxiliary device of the socket type prefabricated multi-arc comprehensive pipe gallery has the following characteristics: simple structure, convenient installation, no damage to the concrete of the socket end of the pipe gallery, lower requirements for the construction machinery and construction personnel on site, and guarantee of the splicing quality and speed of the pipe gallery, effective reduction of the construction period and construction difficulty of the pipe gallery project. BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 is the axial sectional view of the splicing auxiliary device of the socket type prefabricated multi-arc comprehensive pipe gallery of the utility model;
[0013] Figure 2 is Figure 1 the P-P view in DETAILED DESCRIPTION
[0014] The utility model will be further described below with reference to the drawings.
[0015] Please refer to Figure 1 and Figure 2 The splicing auxiliary device of the socket type prefabricated multi-arc comprehensive pipe gallery of the utility model comprises a pair of steel sleeves 2, two pairs of bolts 3, two opposite-pulling steel wire ropes 4 and two hand-operated hoists 5.
[0016] The pair of steel sleeves 2 is symmetrically horizontally pre-buried on the inner side of the middle part of the two side walls 10 of the pipe gallery section 1; before pouring the pipe gallery concrete, the steel sleeve 2 is welded and fixed with the pipe gallery reinforcement, and then the pipe gallery concrete is poured.
[0017] The length of the bolt 3 is greater than that of the steel sleeve 2, and the inner end of the bolt 3 is sequentially provided with a anti-dropping ring 31 and a steel wire rope embedding groove 32; the pair of bolts 3 are one-to-one correspondingly inserted into the pair of steel sleeves 2 on the pipe gallery section 1A to be spliced, and the other pair of bolts 3 are one-to-one correspondingly inserted into the pair of steel sleeves 2 on the pipe gallery section 1B that has been spliced.
[0018] The two opposite-pulling steel wire ropes 4 are one-to-one correspondingly wound between the steel wire rope embedding grooves 32 on the inner end of the pair of bolts 3 on the pipe gallery section 1A to be spliced and the steel wire rope embedding grooves 32 on the inner end of the corresponding pair of bolts 3 on the pipe gallery section 1B that has been spliced.
[0019] The two hand-operated hoists 5 are one-to-one correspondingly connected between the end of the two opposite-pulling steel wire ropes 4.
[0020] When the pipe gallery is spliced, the pipe gallery channel and foundation are excavated and laid first, and a concrete layer with a smooth surface is cast on the bottom surface of the pipe gallery channel. Then, the prefabricated pipe gallery section to be spliced 1A is transported to the installation point in the pipe gallery channel, the splicing auxiliary device of the utility model is installed between the pipe gallery section to be spliced 1A and the pipe gallery section already spliced 1B, then two hand-operated hoists 5 are pulled synchronously, two pairs of pulling steel wires 4 are reeled in one-to-one correspondence, the pipe gallery section to be spliced 1A is pulled to move in the direction opposite to the pipe gallery section already spliced 1B, until the spigot end or the socket end of the pipe gallery section to be spliced 1A is connected with the socket end or the spigot end of the pipe gallery section already spliced 1B, and finally the steel sleeve 2 is sealed by using waterproof mortar 6. The steel wire embedding groove 32 and the anti-disengagement ring 31 on the bolt 3 can prevent the pulling steel wire 4 from disengaging from the bolt 3 when the pipe gallery section to be spliced 1A is pulled, and ensure the continuity and safety of construction.
[0021] The above examples are only used to illustrate the utility model, and are not limited to the utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, all equivalent technical solutions should belong to the scope of the utility model, and should be limited by the claims.
