Abstract
The utility model discloses an underground cavern baseboard pre-buried injected hole. The underground cavern baseboard pre-buried injected hole is characterized in that the pre-buried injected hole comprises a cushion layer injected hole buried pipe which is arranged on a plain concrete cushion layer and a baseboard injected hole buried pipe which is arranged on the baseboard. An injected hole bottom sealing device is arranged at the bottom of the baseboard injected hole buried pipe which is connected with the cushion layer injected hole buried pipe. The underground cavern baseboard pre-buried injected hole has the advantages that during the period of the completion and operation of the underground cavern, the concrete is unnecessary to chisel out while the concrete is cast, and influences on an external waterproof layer are only limited in the aperture range of the injected hole. A casting pipe is capable of simply and directly entering the underground cavern baseboard and a soil body below the concrete cushion layer to carry out casting work.
Description
Technical field
The utility model is applicable to cut and cover tunneling cast-in-situ steel reinforced concrete underground chamber structure (comprising tunnel, subway station etc.) the pre-buried injected hole of base plate.
Technical background
After underground chamber builds up, later stage closely adopts the tunneling method to implement the underground chamber of relevant purposes as shield structure etc. in its underpart, need to consider formerly to build the reserved Grouting Pipe of underground chamber base plate, in case the later stage is implemented Cavity Construction, peripheral soil layer disturbance is affected first build underground chamber foundation soil and then impact first to build cavern stable.Reserve Grouting Pipe by base plate soil layer is carried out to a kind of method that consolidation grouting guarantees first to build the stable normal use of underground chamber.
When former method is met this type of situation, generally at the base plate built-in slip casting pipe, its mouth of pipe has a segment distance (thickness is 50 ~ 250mm approximately) apart from the base plate bottom surface, this scope is cast-in-situ concrete, causes later stage slip casting to cut a hole in advance and wears this section concrete of base plate, must produce certain impact to former underplate concrete, thickness is larger, affects greatlyr, cuts also more bothersome, as outer packaging waterproof layer is set, simultaneously wayward to the influence basin of waterproofing course.
The utility model content
The purpose of utility model is to provide a kind of underground chamber base plate pre-buried injected hole, when later stage slip casting, need not cut concrete, and externally the impact of packaging waterproof layer only limits to Grouting Pipe caliber scope simultaneously.
To achieve these goals, technical solutions of the utility model are: the pre-buried injected hole of a kind of underground chamber base plate, it is characterized in that: this pre-buried injected hole comprises the bed course injected hole pipe laying that is arranged on plain concrete cushion layer and is arranged on the floor grouting hole pipe laying of base plate, pipe laying bottom, described floor grouting hole is provided with the injected hole bottom closing device, and floor grouting hole pipe laying is connected with bed course injected hole pipe laying by this injected hole bottom closing device.Pipe laying top, described floor grouting hole is provided with the injected hole lid that binds.Pipe laying top, described floor grouting hole is provided with the top cover connector, and the described injected hole lid that binds comprises and also is provided with the watertight rubber ring between described top cover and top cover connector by the top cover be threaded with the top cover connector.Described injected hole bottom closing device comprises the flange ring be enclosed within outside pipe laying bottom, floor grouting hole, and pipe laying bottom in floor grouting hole is disposed with back cover steel sheet, dividing plate and bed course, and bed course is outside equipped with flange press ring, and flange press ring is connected with flange ring.Described flange ring has been arranged circumferentially several screws, and each screw all is welded with a bolt capping, and flange press ring and bolt capping are bolted.The outer aperture waterproofing course that pastes in injected hole bottom closing device bottom.
The utility model has the advantage of: owing to needn't cutting concrete, Grouting Pipe can simple and easyly directly be inserted easily the soil body under underground chamber base plate and concrete cushion and carry out the slip casting operation, not only can control the influence basin to concrete structure and waterproofing course, and remove from and cut the concrete construction operation, can reduce the operation duration of the whole grouting and reinforcing soil body, significantly reduce the Influence to operation of first building underground chamber to having come into operation.

Fig. 2 is that in Fig. 1, the B place is injected hole pipe laying bottom closing device sectional detail drawing (for expressing clearly, leaving the space malcompression between each member, material).
Fig. 3 is that in Fig. 1, the A place is the top view that the injected hole pipe laying binds and covers.
Fig. 4 is that the injected hole pipe laying binds and covers sectional drawing.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model is the pre-buried injected hole of a kind of underground chamber base plate, it is characterized in that: this pre-buried injected hole comprises the bed course injected hole pipe laying that is arranged on plain concrete cushion layer and is arranged on the floor grouting hole pipe laying of base plate, pipe laying bottom, described floor grouting hole is provided with the injected hole bottom closing device, and floor grouting hole pipe laying is connected with bed course injected hole pipe laying by this injected hole bottom closing device.
This pre-buried injected hole methods && steps of implementation is as follows.
1. in plain concrete cushion layer, position in accordance with regulations arranges bed course injected hole pipe laying 8(tubing and can adopt the engineering plasticity materials such as PVC, in pipe, can fill cohesive soil 17 or other material).
2. injected hole pipe laying assembly is installed on bed course injected hole pipe laying top, this pipe laying assembly is the auxiliary products that factory manufactures assembly, described injected hole pipe laying assembly comprises floor grouting hole pipe laying, and injected hole binds and covers and the injected hole bottom closing device, and its factory's manufacture and on-site assembly method step are as follows.
(1) factory manufactures
1) floor grouting hole pipe laying 9 and top cover connector 18 weld mutually;
2) the injected hole lid that binds is made by top cover 13(steel) and watertight rubber ring 14 form, top cover 13 installation that is threaded with top cover connector 18;
3) be connected to a flange ring 2 in the 9 bottom outside welds of floor grouting hole pipe laying, these flange ring 2 hoops are established several screws, and the top of each screw is welded with a bolt capping 1(and can adopts steel to make), the welding requirements sealing is not seeped water;
4) processing flange press ring 4(can adopt steel to make simultaneously), to be greater than steel pipe be floor grouting hole pipe laying 9 internal diameters to back cover steel sheet 3(diameter, is less than flange ring 2), dividing plate 5(can adopt the engineering plasticity materials such as PVC), beyond rubber ring flat-plate 12(flange press ring 4 effectively radial dimension should meet waterproofing materials paste require);
