Abstract
The utility model provides one repeatedly slip casing by pressure pipe, comprise outer tube and interior pipe, described outer tube is distributed with once grouting hole, described interior pipe is provided with some secondary grouting passages, described secondary grouting expanding channels inner pipe wall and outer tube wall, described secondary grouting passage outer tube wall one end is provided with unidirectional grouting valve; Described internal tube is provided with adjustable vane, and described adjustable vane is the same with the length of interior pipe, and interior pipe is divided into independently three spaces.This patent designs mainly for the Grouting Pipe of advance support during underground construction shallow buried covered excavation, carries out the stronger repeatedly slip casing by pressure of specific aim to the pre-reinforcement soil body, improves the effect of leading pre-supporting.Major advantage is: construction material is all prefabricated units, is as good as, constructs very convenient with ordinary steel floral tube jacking construction; Can repeatedly any direction; Slip casting is full; Overlap joint good leak-proof effect; Advanced pre-reinforcement quality is guaranteed.
Description
Technical field
The utility model relates to construction engineering technical field, is specifically related to one repeatedly slip casing by pressure pipe.
Background technology
Along with the development of China's modernization, infrastructure scale is increasing, and building region is day by day wide, often will in soft stratum the engineering such as railway construction, highway tunnel and urban subway.On the other hand, the underground engineering construction of modern city more and more causes the safety effects of existing building, pipeline and road to be paid attention to widely, and the safety of surface settlement distortion and existing building, pipeline and road is as modern most important Consideration and Con trolling index.Build in this case, just first must carry out pre-reinforcement to work plane front along tunnel contour line, and then excavate, to ensure construction safety.The method of pre-reinforcement is existing a lot, as static pressure grouting, work plane grouting with small pipe, steel pipe shed pre-support, precutting trough, horizontal jet grouting injection etc.
Engineering construction main material only has several, as: shaped steel, concrete, reinforcing bar, cement, steel pipe.Steel pipe and cement are the materials that advanced pre-reinforcement is comparatively commonly used, because its price is low, the cycle is short, efficiency advantages of higher, apply comparatively extensive in engineering construction, due to shortcomings such as slip casting effect is poor, overlap joint leakproof is not good, difficult quality guarantee, engineering construction is made to there is larger potential safety hazard, the larger distance limiting excavation driving.
Summary of the invention
This patent carries out improvement and bring new ideas for above shortcoming to slip casting steel pipe, on the basis of conventional steel slip casting, provide one repeatedly slip casing by pressure pipe, which increasing can the slip casing by pressure of repeatedly any direction, slip casting is formed full in pre-reinforcement soil layer, overlap joint good leak-proof effect, and the advance support that quality can ensure, also can need according to design and select slip casting direction and slip casting number of times targetedly, effective control surface settlement, ensure the safe handling closing on existing building, good effect is played to the smooth construction of construction of underground structure, there is good future in engineering applications.
The technical scheme that the utility model adopts is as follows: one is slip casing by pressure pipe repeatedly, comprise outer tube and interior pipe, described outer tube is distributed with once grouting hole, described interior pipe is provided with some secondary grouting passages, described secondary grouting expanding channels inner pipe wall and outer tube wall, described secondary grouting passage outer tube wall one end is provided with unidirectional grouting valve; Described internal tube is provided with adjustable vane, and described adjustable vane is the same with the length of interior pipe, and interior pipe is divided into independently three spaces.
Preferably, once grouting hole is evenly arranged ringwise.
The beneficial effects of the utility model comprise:
This patent designs mainly for the Grouting Pipe of advance support during underground construction shallow buried covered excavation, by pre-processed RT many slip casing by pressure pipes, carries out the stronger repeatedly slip casing by pressure of specific aim to the pre-reinforcement soil body, improves the effect of leading pre-supporting.Major advantage is: 1, construction material is all prefabricated units, is as good as, constructs very convenient with ordinary steel floral tube jacking construction; 2, can repeatedly any direction; 3, slip casting is full; 4, good leak-proof effect is overlapped; 5, advanced pre-reinforcement quality is guaranteed.

Fig. 2 is the tube wall schematic diagram of a kind of repeatedly slip casing by pressure of the utility model pipe.
In figure: 1, outer tube, 2, interior pipe, 3, once grouting hole, 4, secondary grouting passage, 5, unidirectional grouting valve, 6, adjustable vane, 7, grouting and reinforcing region.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
One is slip casing by pressure pipe repeatedly, as shown in Figure 1, 2, comprise outer tube 1 and interior pipe 2, described outer tube 1 is distributed with once grouting hole 3, described interior pipe 2 is provided with some secondary grouting passages 4, described secondary grouting passage 4 connects inner pipe wall and outer tube wall, and described secondary grouting passage 4 outer tube wall one end is provided with unidirectional grouting valve 5; Described interior pipe 2 inside is provided with adjustable vane 6, and described adjustable vane 6 is the same with the length of interior pipe 2, and interior pipe is divided into independently three spaces.
Once grouting hole 3 is evenly arranged ringwise.
Above-mentioned embodiment is preferred embodiment of the present utility model; be not for limiting enforcement of the present utility model and interest field; all equivalences made according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model claim.
