Description

A difference settlement orthotic devices for underground pipe gallery construction
Technical Field
The utility model belongs to the building construction equipment field, and the utility model relates to a difference settlement orthotic devices for underground pipe gallery construction that says so belongs to.
Background
The existing underground comprehensive pipe gallery mainly adopts two modes: the first type is a cast-in-place pipe gallery, firstly, foundation pit enclosures are arranged on two sides of a foundation pit to be excavated, then, the foundation pit is excavated, finally, the two sides of the foundation pit are cast in situ to form a pipe gallery, and finally, soil is backfilled to cover the pipe gallery. The foundation pit enclosure is generally formed by connecting rigid sheet piles or cast-in-situ bored piles, and cannot be used as a part of the side wall of the pipe gallery due to poor strength and waterproof performance, the whole pipe gallery main body must be completely cast in situ (steel bar binding, formwork erecting, concrete pouring and maintenance and the like), and the defects of long construction period, high construction cost, inconvenience in application of advanced construction technology and the like exist. The other method is to use an underground continuous wall as a foundation pit enclosure, and although the underground continuous wall can be used as the side wall of a pipe gallery, the construction of the underground continuous wall needs to excavate earth in a large area, the construction period is long, and the cost is quite high. The second kind is whole prefabricated formula square culvert underground pipe gallery, and it exists volume and weight big, brings the manufacturing equipment and requires high, lifts by crane the difficulty, the transportation volume is big, shortcoming such as freight height, in addition, in the work progress of whole prefabricated formula square culvert underground pipe gallery, owing to there is the difference settlement, leads to the butt joint between the pipe gallery to appear the deviation, has influenced the construction effect.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a difference settlement orthotic devices for underground pipe gallery construction has improved construction quality.
The technical scheme of the utility model is that:
a differential settlement correction device for underground pipe gallery construction comprises a prefabricated underground pipe gallery body, the prefabricated underground pipe gallery body is internally provided with a reinforcing rib, the side wall of the prefabricated underground pipe gallery body is provided with a plurality of grouting hole groups along the length direction, the grouting hole group is provided with a plurality of grouting holes, at least three grouting holes are arranged, the grouting holes are arranged at the bottom of the prefabricated underground pipe gallery body, hanging rings are arranged on two sides of the prefabricated underground pipe gallery body, a supporting pier is arranged in the grouting hole in the middle, the support pier is vertically provided with a lifting screw rod, the lifting screw rod is provided with a lifting nut, the lifting nut is connected with the lifting screw rod through a bolt, the lifting nut is provided with a ram, the ram is provided with a through hole, the lifting screw penetrates through the through hole, and two ends of the lifting screw are connected with the lifting ring through a connecting chain.
Further, rings with this internal strengthening rib of prefabricated formula underground pipe gallery is connected, has improved the firm in connection nature of rings.
Furthermore, a supporting plate is arranged on the lifting nut, and the ram is arranged on the supporting plate, so that the supporting stability is improved.
Furthermore, the distance between the lifting rings on the two sides and the lifting screw is equal.
Furthermore, the lifting nut is provided with an operating handle, so that the operation is convenient.
During correction, the lifting rings are connected to two ends of the lifting screw, the lifting nut (lifting sleeve) is rotated through the operating handle, the lifting screw is lifted, the prefabricated underground pipe gallery body is driven to ascend, a certain gap is formed after the prefabricated underground pipe gallery body ascends, grouting is performed through the grouting holes, the gap is filled, and settlement correction is achieved; because the grout hole sets up at the multiunit along length direction along the lateral wall of prefabricated formula underground pipe gallery body, consequently can carry out the multiple spot grout to the bottom of prefabricated formula underground pipe gallery body, makes the grout more even unanimous, avoids only leading to the inner wall to form the space in one side grout, and influences construction quality.
The utility model has the advantages that: the construction quality is improved.
The present invention will be further explained with reference to the drawings and examples.
Drawings
Figure 1 is the embodiment of the utility model provides a difference settlement orthotic devices's that is used for underground pipe gallery to be under construction schematic diagram.
Detailed Description
