Abstract

The utility model relates to a plugging steel sleeve of a dewatering well under a basement floor, and belongs to dewatering well plugging devices in building construction. The plugging steel sleeve is characterized by mainly composed of a steel pipe, waterstop rings, a plugging cover plate, a support rod and a rope, wherein waterstop rings are respectively welded at upper and lower parts on the peripheral surface of the steel pipe; a hinge is welded on the left side at the bottom of the steel pipe and is hinged with the round plugging cover plate; an annular seal gasket is clung onto the upper surface of the plugging cover plate in a position relatively located at the wall of the steel pipe; an n-shaped nose buckle I is welded at the middle part on the upper surface of the plugging cover plate; the support rod is hinged and mounted in the nose buckle I; the right end section of the support rod takes the shape of a hook and corresponds to an n-shaped nose buckle II inserted in the right inner wall of the bottom end section of the steel pipe, so that the plugging cover plate is normally open; and the rope is tied on the support rod. After dewatering is finished, the plugging cover plate can be closed tightly through lifting the rope vigorously in an inclined direction, and micro-expansion concrete is poured in a hole, as a result, use and plugging of the dewatering well reserved dewatering hole are achieved successfully and the plugging quality is ensured.

Description

The shutoff steel sleeve of basement bottom board decline well

Technical field

The utility model belongs to building operations precipitation well plugging device, especially relates to a kind of shutoff steel sleeve of basement precipitation well.

Background technology

At present; City Building is provided with large-scale double-deck basement more and more; Most of basements need adopt the precipitation well to carry out precipitation; Guaranteeing the basement smooth construction, general cycle in precipitation need arrive basement construction and accomplish and backfilling of earthwork completion all around, for base plate be installed with the ater-casting then need precipitation to ater-casting to build completion after; The job site great majority adopt the top that extends on the basement bottom board on the well casing with the precipitation well to stay the precipitation hole at present; To guarantee that accomplishing continued in the basement bottom board construction utilizes the precipitation well to carry out precipitation; But there is following defective in the method: first: the well casing of precipitation well is the plain concrete of common intensity; Intensity is low and do not have the antiseep effect, finally can cause underground water to push up along oozing in the well casing to basement bottom board; Second: the shutoff of reserving the precipitation hole after precipitation is accomplished on the basement bottom board is easy to exist the hidden danger of percolating water.

Summary of the invention

The purpose of the utility model is the shutoff steel sleeve that proposes a kind of basement bottom board decline well; This shutoff steel sleeve is installed in the basement bottom board as the precipitation hole; Carry out the precipitation after basement bottom board is accomplished; Can this precipitation hole of easy, reliable, effective shutoff after precipitation is accomplished, improve the precipitation well is reserved the precipitation hole at the basement bottom board place quality and shutoff quality.

The purpose of the utility model realizes like this: a kind of shutoff steel sleeve of basement bottom board decline well (hereinafter to be referred as the shutoff steel sleeve); It is characterized in that: the shutoff steel sleeve of this basement bottom board decline well mainly is made up of steel pipe, seal ring, shutoff cover plate, support bar and stay cord; The seal ring that is welded respectively in the upper and lower of steel pipe outer peripheral face, the diameter of this steel pipe can be 150mm and length greater than the thickness 200mm of basement bottom board, the hinge (hinge) and hinged of being welded in the left side of the bottom of steel pipe is installed circular shutoff cover plate; This capping board diameter is greater than diameter of steel tube 40mm-60 mm; Gask-O-Seal is pasted at the position that is positioned at steel pipe walls in the upper surface correspondence of shutoff cover plate, and this sealing mat can be rubber pad, and the ∩ shape nose that is welded at the middle part of the upper surface of shutoff cover plate is buckled I; Hinged installation support bar in this nose button I; The right-hand member section of this support bar is hook-type and the corresponding ∩ shape nose that is inserted on the right inwall of steel pipe bottom section is buckled in the II, is in normal opening to guarantee the shutoff cover plate, on the hook-type section of this support bar, binds the stay cord that stretches out steel pipe; This stay cord can be wire rope, and this support bar can be processed with the reinforcing bar of Φ 6 mm.

Before building the basement floor concrete; The shutoff steel sleeve of this basement bottom board decline well position according to the precipitation well is installed in the basement bottom board as reserving the precipitation hole; And the center of circle of guaranteeing both overlaps, and shutoff this moment cover plate is in normal opening through they sup-port, builds the basement bottom board concrete then; In simultaneously the shutoff steel sleeve being cast in, and carry out precipitation through this reservation precipitation hole; After treating that precipitation stops; Remove the precipitation device in the underground precipitation well; Close the shutoff cover plate tight through the stay cord oblique lifting of exerting oneself; In reserving the precipitation hole, build slightly expanded concrete and maintenance then, finally complete successfully the precipitation well and reserve the use and the shutoff in precipitation hole and guaranteed the shutoff quality.

The shutoff steel sleeve of the basement bottom board decline well that the utility model proposed, not only rational in infrastructure, safe and reliable, and improved the service efficiency of basement precipitation well and the shutoff quality in reservation precipitation hole greatly, reduced construction cost.

Combine accompanying drawing and embodiment that the shutoff steel sleeve of the basement bottom board decline well that the utility model proposed is described further at present.

Description of drawings

Fig. 1 is the main cross-sectional schematic of the shutoff steel sleeve of the basement bottom board decline well that proposes of the utility model when using.

Among Fig. 1: 1, steel pipe 2, seal ring 3, shutoff cover plate 4, sealing mat 5, hinge 6, support bar 7, stay cord.

The specific embodiment

As can be seen from Figure 1: a kind of shutoff steel sleeve of basement bottom board decline well (hereinafter to be referred as the shutoff steel sleeve); It is characterized in that: the shutoff steel sleeve of this basement bottom board decline well mainly is made up of steel pipe 1, seal ring 2, shutoff cover plate 3, support bar 6 and stay cord 7; Seal ring 2 is welded respectively in the upper and lower of steel pipe 1 outer peripheral face; The diameter of this steel pipe 1 can be 150mm and length greater than the thickness 200mm of basement bottom board; The hinge (hinge) 5 and hinged of being welded in the left side of the bottom of steel pipe 1 is installed circular shutoff cover plate 3, and the diameter of this shutoff cover plate 3 is greater than diameter 40mm-60 mm of steel pipe 1, and Gask-O-Seal 4 is pasted at the position that is positioned at steel pipe walls in the upper surface correspondence of shutoff cover plate 3; This sealing mat 4 can be rubber pad; The ∩ shape nose that is welded at the middle part of the upper surface of shutoff cover plate 3 is buckled I, hinged installation support bar 6 in this nose button I, and the right-hand member section of this support bar 6 is hook-type and the corresponding ∩ shape nose that is inserted on the right inwall of steel pipe 1 bottom section is buckled in the II; To guarantee that shutoff cover plate 3 is in normal opening; On the hook-type section of this support bar 6, bind the stay cord 7 that stretches out steel pipe 1, this stay cord 7 can be wire rope, and this support bar 6 can be processed with the reinforcing bar of Φ 6 mm.
