Description
Technical field
The utility model belongs to the technical field of construction work slip casting, particularly relates to the grouting device that a kind of integrating tunnel section of jurisdiction reinforces poor strata.
Background technology
Along with the construction and development of China's subway engineering decades, in process of construction or in the circuit runed, the various diseases of often various degrees, drastically influence the safety of engineering construction quality and broad masses of the people.Wherein, owing to being in unfavorable geology (clay, mud) bottom subway tunnel, early stage synchronous grouting and secondary grouting after still can not meet Soft Soil Layer bearing capacity prerequisite under, for preventing Soft Soil Layer depression under the effect of long-term train vibration load, cause tunnel structure differential settlement, cause comfortableness by bus and safety, need formation to carry out soil stabilization according to designing requirement.Sleeve valve barrel grouting traditional is at present only limitted to from ground to surface drilling, slip casting, its construction technology has limitation, in subway tunnel poor strata strengthening construction, due to the existence of section of jurisdiction, need the reserved injected hole slip casting again of abolishing section of jurisdiction, consider that gap between section of jurisdiction and mini-valve tube uses sleeve shell material to meet execution conditions, need a kind of can by the grouting device of compact siro spinning technology section of jurisdiction preformed hole, and when can prevent slip casting, slurries flee hither and thither.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned Problems existing, provides the grouting device that a kind of integrating tunnel section of jurisdiction reinforces poor strata.
The utility model solves the problems of the technologies described above adopted technical scheme: the grouting device that a kind of integrating tunnel section of jurisdiction reinforces poor strata, it is characterized in that, comprise slip casting sleeve pipe, seal nipple, mini-valve tube and slip casting core pipe, described slip casting sleeve pipe is located in the injected hole of tunnel duct piece, and slip casting sleeve pipe is for establishing female hollow cylindrical structure; Described seal nipple is for being provided with externally threaded hollow cylindrical structure, and seal nipple inserts in described slip casting sleeve pipe and is connected with slip casting casing threads; The top of described mini-valve tube is connected with the bottom of described seal nipple; Described slip casting core pipe stretches into the internal cavities of described mini-valve tube from the internal cavities of described seal nipple.
By such scheme, the top of described mini-valve tube and the bottom interference fit of described seal nipple, the endoporus bottom of described seal nipple is provided with stage portion, and the top of described mini-valve tube is located by described stage portion.
By such scheme, the position that the top of described seal nipple contacts with described slip casting sleeve pipe is provided with sealing device, and the position that the bottom of seal nipple contacts with the top of described mini-valve tube is provided with sealing device.
By such scheme, described sealing device is rubber seal.
The beneficial effects of the utility model are: provide the grouting device that a kind of integrating tunnel section of jurisdiction reinforces poor strata, slip casting object can be reached by the seal nipple of compact siro spinning technology section of jurisdiction preformed hole, and slurries flee hither and thither when can prevent slip casting, reach after intensity until grouting serous fluid and can take out seal nipple recycling.

Fig. 2 is the structural representation of the utility model embodiment.
Wherein: 1. slip casting sleeve pipe, 2. seal nipple, 3. mini-valve tube, 4. slip casting core pipe, 5. tunnel duct piece, 6. rubber seal.
Detailed description of the invention
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1-2, the grouting device that a kind of integrating tunnel section of jurisdiction reinforces poor strata, comprise slip casting sleeve pipe 1, seal nipple 2, mini-valve tube 3 and slip casting core pipe 4, slip casting sleeve pipe is located in the reserved injected hole of tunnel duct piece 5, slip casting sleeve pipe 1 is for establishing female hollow cylindrical structure, seal nipple 2 is for being provided with externally threaded hollow cylindrical structure, and seal nipple inserts in slip casting sleeve pipe and is connected with slip casting casing threads; The top of mini-valve tube 3 and the bottom interference fit of seal nipple 2, the endoporus bottom of seal nipple is provided with stage portion, and the top of mini-valve tube is located by stage portion; The internal cavities that slip casting core pipe 4 stretches into mini-valve tube 3 from the internal cavities of seal nipple 2 carries out grouting operation; The position that the top of seal nipple 2 contacts with 1 slip casting sleeve pipe is provided with rubber seal 6, and the position that the bottom of seal nipple contacts with the top of mini-valve tube 3 is provided with rubber seal 6.
This grouting device is when grouting operation, first after soil layer is holed and injected sleeve shell material to the outer diameter face of tunnel duct piece 5 (drilling depth is tunnel duct piece outer diameter face down 2 meters), again mini-valve tube 3 is inserted the endoporus of seal nipple 2, rubber seal is utilized to carry out clearance seal, after linking together, the injected hole reserved by tunnel duct piece inserts soil layer until the silk tooth of seal nipple and slip casting sleeve pipe 1 carry out screw thread compact siro spinning technology, for preventing grout or grout leaking, apply mechanically rubber seal 6 at joint and the sleeve pipe place of being close to seal, then carry out slip casting by slip casting core pipe.
