Abstract
This utility model relates to the slip casting bag buried pipeline basis of a kind of band pipe pillow, it is characterised in that: including pipe pillow and slip casting bag, described slip casting bag is connected to pipe occipital portion, and slip casting bag is provided with the grouting mouth for cement injection mortar in slip casting bag.This utility model simple in construction, can directly in-site installation, easy construction safety, the duration is short, can synchronization implementation on a large scale.
Description
Technical field
This utility model relates to outdoor buried pipe installation technology, the slip casting bag buried pipeline basis of a kind of band pipe pillow, belongs to urban operating mechanism technical field.
Background technology
In the installation practice carrying out outdoor buried pipeline, excessive and occur interface to destroy owing to producing bending stress in order to prevent pipeline operationally, and because part is made the rough sledding such as tube wall ruptures be occurred, so must there be good foundation support below pipeline by excessive supporting force.General selection concrete duct basis in engineering at present, it is to lay the thick plain concrete of certain thickness or blotter bottom the pipe trench meeting design bearing capacity requirement, after bed course intensity reaches installation requirement, assembling reinforcement on bed course, installation form, joints cement concrete makes flat base, and the flat base of precast concrete need to carry out maintenance, then form removal, fixes a drainpipe.
But above-mentioned Guan Ji is only applicable to the preferable region of foundation bearing capacity, and concrete duct foundation construction length curing cycle, wasting manpower and material resources.
A kind of piping infrastructure with the soft capsule of cement mortar is disclosed in the Chinese patent application of Publication No. CN202834383U, it is equipped with multiple by being perfused with the soft capsule of cement mortar of cement mortar in the soft capsule sealed between pipeline and soil layer, and the soft capsule of cement mortar supporting plate is arranged below.This patent application have employed grouting cement soft capsule as pipeline foundation, but the cement liquid not yet in the cement soft capsule not condensed, it being difficult to accomplish compacting, the security and stability of its structure also is difficult to ensure.And when pipe laying, owing to lacking fixing support.Elevation and the straight cis degree of pipeline are also difficult to control to.Additionally when constructing on a large scale, for avoiding theing cement solidifies in capsule, it is necessary to on-the-spot grouting backfill, limit its large-scale use space.The most above-mentioned drainage pipeline basis, on using, has still suffered from inconvenience and defect, it would be highly desirable to be further improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the slip casting bag buried pipeline basis of a kind of band pipe pillow, its simple in construction, can directly in-site installation, easy construction safety, the duration is short, can synchronization implementation on a large scale.
The technical scheme provided according to this utility model: the slip casting bag buried pipeline basis of a kind of band pipe pillow, it is characterized in that: include pipe pillow and slip casting bag, described slip casting bag is connected to pipe occipital portion, and slip casting bag is provided with the grouting mouth for cement injection mortar in slip casting bag.
As a further improvement on the present invention, the top of described pipe pillow is provided with the groove for disposing pipeline.
As a further improvement on the present invention, described groove is arc or V-arrangement.
As a further improvement on the present invention, described pipe pillow uses plain concrete to make, or is made up of armored concrete, or is made up of foamed light soil.
As a further improvement on the present invention, described slip casting bag is the airtight bag shaped structure being woven into by geotextiles.
This utility model compared with prior art, has the advantages that
1), pipe pillow, slip casting bag can factory the most prefabricated, field conduct is convenient, construction quality is controlled.
2), pipe pillow for rigid structure, pipeline can be directly supported；And pipe pillow is provided with groove, when pipe laying, convenient and swift, can well control elevation and the straight cis degree of pipeline, can reduce difficulty of construction accelerating construction progress.
3), by grouting mouth can at the scene with project progress at any time to slip casting bag slip casting, need not worry the impact that pipeline foundation is shaped by slip casting solidification, and slip casting arranges simplicity and is easy to get and can adapt to different construction site on a large scale, applied widely.
4), slip casting bag is had to encase due to cement mortar, certain pressure can be born, cement mortar will not solidify within a period of time simultaneously, so the soft capsule of described cement mortar and the mutual contact such as pipeline outer wall, following soil layer all can be highly uniform and tight, make various stress all effectively be disperseed, be applicable to the relatively low place of bearing capacity.
5), cement mortar has the protection of slip casting bag; will not run off; it is not afraid of the dipping of subsoil water and washes away yet; and the position of pipeline and elevation directly by pipe pillow control do not worry causing pipe joint flexural deformation in later stage trench backfill construction wrong; therefore can carry out trench backfill without slip casting solidification forming in slip casting bag by the time, be greatly improved construction speed.

Fig. 2 is the A-A face structural representation in Fig. 1.
Fig. 3 is the construction schematic diagram of this utility model embodiment.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the slip casting bag buried pipeline foundation main of the band pipe pillow in embodiment to be made up of pipe pillow 1 and slip casting bag 2, and described slip casting bag 2 is connected to pipe and rests the head on 1 sidepiece, and slip casting bag 2 is provided with the grouting mouth 3 for cement injection mortar in slip casting bag 2.
As shown in Fig. 1 ~ Fig. 3, in the present embodiment, the top of described pipe pillow 1 is provided with the groove 1a for disposing pipeline 4, in order to laminating pipeline 4 outer surface, it is simple to the installation of pipeline 4.Groove 1a in embodiment is arc, but in actual processing and manufacturing, described groove 1a can also be V-arrangement.
In the present embodiment, described pipe pillow 1 is made up of plain concrete, or is made up of armored concrete, or is made up of foamed light soil.Described slip casting bag 2 is the airtight bag shaped structure being woven into by geotextiles.
As it is shown on figure 3, Specific construction step of the present utility model is as follows:
(1), channel excavation puts in place；
(2) the design precalculated position, pipe pillow 1 being positioned in ground and absolute altitude；
(3), by pipeline 4 it is placed in the groove 1a of pipe pillow 1, owing to prefabricated pipe pillow 1 is rigid structure, therefore pipeline 4 can well be maintained position and the absolute altitude of setting, be unlikely to skew；
(4), by grouting mouth 3 to slip casting bag 2 slip casting；
(5), trench backfill is carried out；
(6), after installation, the cement mortar in slip casting bag 2 will cure hard, form complete concrete duct 4 basis, long-term stable support can be kept.
