Abstract
The utility model relates to the technical field of long distance pipeline top pipe construction, and particularly relates to a steel pipe cap used for a top pipe in a silty sand district. The steel pipe cap is added in the front of a reinforced concrete sleeve, a top ring is added in the front of the reinforced concrete sleeve in the steel pipe cap, three-point, six-point, nine-point, twelve- point positions of the top ring are respectively provided with a lifting jack support and lifting jacks are arranged through the lifting jack supports; lifting jack pads are arranged among the lifting jacks and the top ring, the two sides of each lifting jack are provided with top ring stiffening plates, and one side of each lifting jack support is fixedly provided with a support stiffening plate; and the front of the steel pipe cap is added with six steel grating baffles. The steel pipe cap provided by the utility model realizes that the resisting force is reduced in silty sand top pipe construction, the landslide is prevented, the construction schedule is improved, and the top pipe traversing construction quality is improved; and the shortages that the existing silty sand highway top pipe construction is easy to cause a road surface to sink is overcome.
Description
Technical field:
The utility model relates to a kind of long distance pipeline pipe jacking construction technique field, and particularly a kind of silty sand location push pipe is used the steel pipe cap.
Background technique:
Grand celebration-Jinxi crude oil pipeline engineering the 4th bid section, the 5th bid section are positioned at area, Tieling, Liaoning Province, and wherein 6 of high-grade highways are passed through in Kaiyuan City, Tieling, comprise that the S303 provincial highway passes through 2 times; G102 national highway 2 times passes through Shen Si expressway, Kazakhstan, Shen expressway each 1 time, and the soil property major part is a silty sand; Soil property is soft, becomes arch property relatively poor, and it is excessive that artificial soil digging causes the space in sleeve pipe the place ahead in jacking construction; Cause the road surface to sink easily, serious appearance road surface subsides.
The model utility content:
The technical problem that the utility model will solve provides a kind of silty sand location push pipe and uses the steel pipe cap, and this steel pipe cap has realized in the silty sand jacking construction, reducing resistance, anti-landslide, has improved construction speed, improves push pipe crossing construction quality.Overcome the deficiency that existing silty sand highway jacking construction causes the road surface to sink easily.
The technological scheme that the utility model is taked is: a kind of silty sand location push pipe is used the steel pipe cap, comprises steel pipe cap and reinforced concrete sleeve; Before reinforced concrete sleeve, add the steel pipe cap; Add apical ring before the reinforced concrete sleeve in the steel pipe cap; 3 points, 6 points, 9 points, 12 positions at apical ring are provided with the jack support respectively and through the jack support jack are installed, and are provided with jack pad between jack and the apical ring, and the apical ring stiffening plate is equipped with in the jack both sides; Jack supports a side and is fixed with the support reinforcing plate, and steel pipe cap the place ahead is equipped with 6 road steel grating baffle plates.
Steel pipe cap external diameter is 1850mm, and internal diameter is 1810mm, and length is 1600mm, and thickness is 20mm.Apical ring thickness is 100mm.The steel grating barrier width is 300mm.
The beneficial effect of the utility model is: the utility model has been owing to adopted the mode of jacking steel pipe cap construction, thus greatly reduce the push pipe operation resistance, improve construction speed; Because jacking construction soil digging operation is carried out in the steel pipe cap all the time, and has increased the steel grating baffle plate, thereby has effectively avoided the silty sand earth fall to fall, and has reduced and has passed through risk; Owing to increased by 4 jack, thereby had the function of adjustment axis and centre deviation, improved and passed through quality, guarantee to pass through successfully; Owing between reinforced concrete sleeve and steel pipe cap, increase apical ring, thereby make between reinforced concrete sleeve and the steel pipe cap and take face contact, avoided a little contacting and caused the concrete sleeve damage.In addition, the utility model can reuse, and has the advantage of saving construction period and construction cost, having increased economic benefit.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment:
Like Fig. 1, shown in Figure 2, a kind of silty sand location push pipe is used the steel pipe cap, comprises steel pipe cap 1 and reinforced concrete sleeve 9; Before reinforced concrete sleeve 9, add steel pipe cap 1, steel pipe cap 1 external diameter is 1850mm, and internal diameter is 1810mm; Length is 1600mm; Thickness is 20mm, and operator construct in steel pipe cap 1 always, avoids highway the phenomenon of caving in to occur; Every jacking 300mm carries out once-through operation, finishes until push pipe; Add apical ring 2 before the reinforced concrete sleeve 9 in steel pipe cap 1, apical ring 2 thickness are 100mm, guarantee between reinforced concrete sleeve 9 and the pipe cap to avoid appearance point to contact for face contact, cause reinforced concrete sleeve 9 local pressures to damage; 3 points, 6 points, 9 points, 12 positions at apical ring 2 are provided with jack support 6 respectively and support 6 through jack jack 4 is installed, and are convenient to adjust the jacking direction of sleeve pipe; Be provided with jack pad 3 between jack 4 and the apical ring 2; Apical ring stiffening plate 5 is equipped with in jack 4 both sides; Jack supports 6 one sides and is fixed with support reinforcing plate 7, and steel pipe cap 1 the place ahead is equipped with 6 road steel grating baffle plates, 8 retaining soil, and steel grating baffle plate 8 width are 300mm; Avoid the 1 the place ahead sand landing of steel pipe cap, cause highway to subside.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technological scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
