Description
Technical Field
The utility model relates to a sleeve pipe construction technical field in the push pipe specifically is a supplementary installation device and supplementary installation external member that is used for sleeve pipe construction in the push pipe.
Background
The pipe jacking construction technology is a common technology in modern pipeline construction. The underground pipeline can be laid without damaging the surface layer. Can reduce the excavation, reduce the degree of destroying soil layer integrality, more can realize laying of pipeline in the underground on city ground traffic or river mountain region surface, reduce the construction degree of difficulty to a certain extent, shorten the engineering time. In pipe-jacking construction, a pipe-jacking machine is usually used to jack a pipe-jacking of concrete, steel, etc. into the soil to form a pipeline channel, and then the pipeline channel formed by the pipe-jacking is filled with a sand bag, sand, etc. cushion layers, or a steel plate track is laid, and then a required casing pipe is pushed into the pipeline channel to complete the installation of the pipeline. Such prior art techniques have limitations. Firstly, sand or steel plates and the like are paved in the whole top pipe, so that the economic cost is high, the consumed time is long, and the required manpower is large. Secondly, after the cushion layer or the track is laid, the sleeve needs to be placed on the cushion layer or the track and then pushed or pulled, and direct friction is generated between the sleeve and the cushion layer or the track. If the sleeve is provided with the rust-proof layer or the heat-insulating layer, the outer layer of the sleeve is very easy to be damaged by friction with a cushion layer or a track in the pushing and pulling process, and the use performance of the sleeve after the sleeve is arranged is further influenced.
CN213776627U discloses a transportation trolley for construction of a jacking pipe and an inner sleeve, which is novel in structure and can adjust the distance between two sets of arc-shaped support plates. The bearing steel wheel rolls in the jacking pipe, so that friction force can be reduced, the corrosion-resistant layer outside the sleeve is prevented from being damaged, and butt welding of the sleeve is facilitated. It is connected between arc backup pad and the sleeve pipe body through the welded mode, has reduced the inboard friction of sleeve pipe and push pipe, has increased the protection to the sleeve pipe. The arc backup pad no longer dismantles after the welding installation, belongs to one shot forming, and the cost is low, and the practicality is strong, reduces the potential safety hazard, improves the efficiency of construction simultaneously, and the bearing steel wheel can contact with the inboard bottom of push pipe, can regard as the important component part of the anti-floating measure of the inboard and sleeve pipe outside concrete filling of later stage push pipe. But it does not allow the elevation of the bushing to be adjusted in the vertical direction but only to a fixed height. When the fixed height is not equal to the height required for butt welding of the sleeve, butt welding of the sleeve is adversely affected.
CN213206756U discloses a device for installation of push pipe inner sleeve, which is simple in structure, saves materials, and the used materials are convenient to process. The elevation of the sleeve can be adjusted, and after the adjustment, the elevation of the sleeve can be kept fixed in the mounting process of the sleeve. The sleeve pipe can slide back and forth in the jacking pipe, and the support stability of the whole arc-shaped support can be ensured. The manufacturing cost is low, the operation is convenient, and the practicability is strong. However, the means for adjusting the elevation of the structure are also means for supporting the weight of the supported casing, which are movable means with adjustable height and are small in number and liable to be damaged in the case of large loads. And the position and the angle of the pulley are fixed, so that the pulley cannot adapt to the bearing angle and the position required by different pipe diameters, and the pulley is easy to abrade the same position of the jacking pipe for a long time in the transportation process, so that the jacking pipe is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above-mentioned defect that exists among the prior art, provide a sound construction, can adjust supporting height, and simple to operate simple structure can be used to the bearing including the supplementary installation device and the supplementary installation external member of the interior sleeve pipe construction of being used for of all kinds of pipe fittings such as steel pipe or insulating tube in the push pipe.
The utility model provides an supplementary installation device and supplementary installation external member that is used for interior sleeve pipe construction of push pipe adopts following technical scheme:
the utility model provides an supplementary installation device for sleeve pipe construction in push pipe, includes arc steel sheet and two sets of sliding assembly, sliding assembly installs in the outside of arc steel sheet, sliding assembly include the base plate with set up in the gyro wheel of base plate bottom, the bar hole that is used for installing sliding assembly is offered to both sides on the arc steel sheet, the screw has been seted up on the base plate, through passing between sliding assembly's the base plate and the arc steel sheet bar hole can be dismantled with the heightening bolt of screw and be connected.
By adopting the technical scheme, compared with the prior art, the method has the following advantages:
through changing the fixed position of the height-adjusting bolt, the device can be adjusted to the elevation of the supported pipe fitting.
The height-adjustable bolts are fixed at different positions through selecting the strip-shaped holes, so that the position of the sliding assembly on the arc-shaped steel plate can be adjusted to a certain degree, the size of an included angle of the sliding assembly relative to the circle center of the arc-shaped steel plate is adjusted, and the supporting angle is adjusted.
When the number of the sleeves conveyed into the jacking pipe is large and the weight is heavy, the supporting angles of different sleeves are adjusted, so that the phenomenon that the jacking pipe is damaged due to the fact that the rollers frequently abrade the same position in the jacking pipe when the sleeves are conveyed in the jacking pipe is avoided.
According to the sleeves with different pipe diameters, the supporting position of the sliding assembly is adjusted, so that the device achieves the best supporting effect on the pipe fittings. For example, when the pipe diameter of the sleeve is smaller, the distance between the two groups of sliding assemblies is properly reduced, the supporting angle is reduced, and vice versa when the pipe diameter is larger.
Optionally, the number of the screw holes in the base plate is consistent with the number of the strip-shaped holes in one side of the arc-shaped steel plate, and the number of the screw holes is three to five.
When the screw was selected three to five, both can guarantee to increase the quantity of bolt in order to prevent that base plate or arc steel sheet from taking place to destroy because of stress concentration through increasing, can avoid the screw to set up too much again and destroy the intensity of steel sheet itself.
